Continuously Monitor your Fire Installations Against the Risk of Leaking

To prevent fires, regulations require installation of a fixed fire protection system and annual maintenance by a licensed servicing company to check its condition. Following from the above it is now possible to go above and beyond the regulation requirement of annual maintenance which may not be sufficient to cover the remaining periods when the vessel is out at sea alone. The idea of continuous monitoring of fire suppression systems has been made possible and is done by non-invasive ultrasonic liquid level monitoring of the contents within the fire suppression cylinders. This ensures the quantity of agent required to extinguish a fire is always at its designed concentration to guarantee an efficacious fire protection in the event of a fire breaking out in the vessel.

Liquid level monitoring is done using compact, low-cost ultrasonic sensors that are linked to a central control module that broadcasts the liquid level information over WSN allowing dissemination of information to the appropriate parties. The ultrasonic sensors are attached to the walls of the cylinders and propagates ultrasound pulses which travel across the cylinder and returns to its starting position. As the ultrasound pulses travel across the cylinder, the contents within the cylinder will absorb the signal energy in proportions relative to their phases. This ensures that the difference in returned signal above and below the liquid level is always sufficiently large, allowing the liquid level to be identified each time. By fixing the sensor onto the cylinder permanently, any changes in the contents’ level will be identified immediately. Research conducted in the labs have proven accuracies up to 0.1 mm when tested with the commonly known fire suppressing agent cylinders. This proprietary system by Coltraco Ultrasonics is the Permalevel® Multiplex and is capable of using the latest advancement in IoT to collect and disseminate sensor information and forwards them onto the control panel situated on the vessel’s bridge to be integrated as part of the vessel’s overall monitoring system.

Features of Permalevel® Mutliplex

This continuous fire suppression monitoring system is considered to be an accurate and reliable measuring system with integration of ultrasonic leak detector. Here, we have provided you with the major features of Permalevel® Multiplex:

  • Status of each channel shown by LEDs: A set of red and green LED lights specify the status of every cylinder which facilitate a team for maintenance which are responsible to check for the cylinders in case any leakages are absorbed.
  • Multiple Alarm Levels: 2 -40mA Relay Alarms are actually connected to all the channels whereas it permits local alarms to organize for each cylinder individually.
  • Uninterruptable Power Supply (UPS): It acts as a backup system which helps in providing power by using AA 1.5V batteries in case the failure occurs of the main power.
  • Optional Text/Email Alerts: This helps in convenient and instantaneous form of data communication.
  • Strong Magnets: These are beneficial to stick the sensors in place along with extra space for adhesive and a strap which ensures the risk of accidentally removing of sensors.
  • Data logging Ability: The software keeps logs of system errors, system activity and alarm triggers for every month. Due to the storage of these logs as simple texts files, they can be easily and conveniently viewed from outside and inside of the software. This is really helpful and advantageous for insurance companies due to the permanent and correct record of the functioning system accurately.
  • Compatible with Multiple Cylinder Types: Tuning of every channel is individually possible. Moreover, it is done because every cylinder can be different from the last one in weight, size, and pressure and agent type.
  • Sensors: Dedicated sensors are available with each monitoring point which is connected to the particular cylinder for monitoring purposes.
  • Remote Real Time Monitoring Screen: It gives off the information about the current condition of the cylinders in regards to the last contact have been made.

How can fire threaten the aluminium industry?

When aluminium is burned, it creates a very intense fire. The industry directly creates more than 155,000 jobs and is adding more yearly. With growing numbers of employees in the aluminium industry, their safety and well being has long been a commitment. There is a need for comprehensive fire safety measures, specifically the fixed fire extinguishing systems in aluminium production and fabrication, in casthouses, foundries, recycling and reclamation plants.

The Permalevel® MULTIPLEX which is designed for permanent contents verification. The continuous monitoring system utilises ultrasound technology to detect the level of contents non-invasively and transmits the level information from the wired sensors to the main unit which is then processed and reported to the building’s BMS or local control panel wirelessly through TCP/IP. This is to ensure that fire suppression systems are always stored at their designed concentration and that no accidental discharge has occurred, which could affect the effectiveness of the overall fire protection system in the event of a fire. The neglect of continuous monitoring - of the fundamental protection provided by the gaseous extinguishing systems - is to the peril of the lives of occupants of the premises and at the risk of causing financial and reputational loss to the facility comprising the critical infrastructure.

The system developed utilises the Internet of Things (IoT) to achieve its full potential of visualising the monitored contents worldwide. IoT enables a worldwide transmission of data starting from sensor to sensor to the microprocessors and to the facilities manager or maintenance team. Instead of waiting for annual checks, owners and building managers can now identify any changes to their installed fire suppression system contents in real time and dispatch their servicing or maintenance team as soon as notification is received about a change happening to the installed system. This is now entirely possible through the reliance on recent IoT developments.

Improve Onboard Safety Management System with Portalevel® MAX Marine

Fires on board ships can be devastating, to crew, vessel and cargo. Fire safety standards on board cannot afford to slip. Part of this issue is to do with the maintenance of gaseous fire extinguishing installations which may be a result of the holes in the regulations. With the recent difficulties that the shipping industry is facing, Coltraco understand that need for practical cost efficient solutions to safety issues.  However, maintaining high standards of fire safety practice does not have to be expensive or time consuming, Coltraco strive to provide easy and long lasting solutions that are suitable to varying budgets. There is a call to respond to regulations with a rigorous attitude, to go above and beyond, to provide security of life and infrastructure. Installations must be maintained so that they can provide the protection that they are intended for. This is a call for awareness of the problem and action to be taken now.

Fire at sea: the proof is in the stats

At sea, fire poses one the of biggest threat to ships. Sailing alone and at sea throughout the year, and without the ability to call upon the emergency services as a land-based asset might. The danger is shown in the statistics. A study published by the Finnish Transport Safety Agency showed that almost 800 fires happened in European waters between 2004 – 2014, 10% of these were classed as serious. Further to this, circa 200 of these incidents required external support to deal with the fire. In some of these cases the fire suppression installations may not have been at their full capacity, which lead to the uncontrollable fires.

Devastating effects of fire & water ingress

A clear of example of where actuation has failed to provide safety to the vessel is MSC Flaminia. In July 2012, the container ship was exposed to an uncontrollable fire which tragically lead to three fatalities and two severely injured crew members, as well as dire damage to the ship structure and its cargo. In this example, the actuation of the CO2 system failed when it actuated without instruction in the engine room, although the discharge was intended for cargo hold 4, which turned off the auxiliary boiler and auxiliary fan for the main engine. This led to an out of control fire which required three salvage tugs to deal with the effects of the explosions and fire. However, the extent of the fire meant that the salvage teams could not enter the vessel for 4 days. Cargo areas 3-7 in the ship were significantly damaged and the ships structure was weakened, requiring replacement. Under the pressures, the hatch covers lost their integrity and bulkheads were severely damaged which led to water ingress in all the cargo.

What about you?

Could you afford for this crippling financial, physical and reputational damage to happen to your crew and vessel? The correct answer for any ship owner, ship manager and P&I club is “No.” Chances must not be taken when lives are at risk, and when a vessel is at sea, this is all the time. We call this the “ungoverned space”. Simply put, the ungoverned space is the area where either the regulations or the protecting systems of the critical infrastructure are not effectively providing consistent and reliable safety. This life-threatening issue must be dealt with, with specific regard to loss of contents in fixed fire extinguishing systems and need for improvements to room integrity testing.

Cutting through to what you need to know

Gaseous extinguishing installations are difficult systems. There are few who understand them in all their complexity. Vessels extinguishing installations are its essential defence against the risk of fire at sea. The main factor that needs to be understood is that they must be able to actuate, or release their gas, in the event of a fire. Surely an extinguishing instillation should extinguish? This may seem like an obvious point, but on further investigation the difficulties with this statement arise. What if the extinguishing instillation cannot actuate fully because there isn’t enough gas within the cylinder? Gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use, shown in the regulations that demand their upkeep e.g. IMO SOLAS FSS Ch5. 2.1.1.3:

“Means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the container”

Often this is misunderstood, this code specifically states that the crew must test their extinguishing installations in between the periodic inspection, maintenance and certification. Only having the annual inspection by accredited marine servicing companies is not enough – the crew must take responsibility for its own fire protection.  However, what must be noted is that the crew are often not trained or certified to shut-down, dismantle, weigh and re-install the gaseous cylinders.

Adding to this, the details of their leakage within the regulations which is troubling. ISO 14520-1 clearly states that:

If a container shows a loss of agent quantity or a loss of pressure (adjusted for temperature) of more than 5 %, it shall be refilled or replaced

Given that the gaseous systems are designed specifically to the individual need of the vessel then a 5% loss of agent may mean that they would not fully extinguish the fire. In a recent article by the Maritime Executive, Captain Madden urged crews to routinely and properly inspect and test fixed firefighting systems; “too often they are found with… concerns about leakage”. The only way to determine a cylinder is free from leakage is to check its contents. But if the crew cannot weigh their own cylinders, because they are not certified to do so, then how is it possible?

CO2 UK Marine Equipment Directive (MED) UK/EU legislation with US Coast Guard Mutual Recognition 7.3.2.6:

Means should be provided to verify the liquid level in all the cylinders, either by weighing the cylinders or by using a suitable liquid level detector.”

Case Study: Carnival Cruises sought Coltraco Ultrasonics’ expertise

“Ships sink; fires happen”. Addressing these two main causes of vessel loss are critical, especially when all owners and managers are seeking to reduce risk, cut costs and surge on safety. Carnival Cruises chose to protect their fleet by improving fire safety. One aspect of this is that they chose Coltraco Ultrasonics to be their supplier for the Portalevel® MAX Marine which tests the CO2 fire installations onboard for leaks in content.

FIRETEST SOLUTIONS TO DELIVER THE SAFESITE IN WIND TURBINES

With some turbines at almost 200m in height, they are effectively outside the range of the fire emergency services; and when it comes to turbines at sea, human intervention in the event of fire is virtually impossible. It is for this reason that the NFPA 850 Recommended Practices suggest guidelines and AHJs and other fire inspectorates, consultants, associations, the insurance companies and the OEMs themselves all have a role in play in developing good codes of conduct.

Wind turbines require an active fire protection system, which includes but is not limited to detection (of flames, heat, gas, and smoke), alerting personnel and rescue services, and activating systems for fire suppression or extinguishing. Due to the height and location of wind turbines, classic firefighting methods come up against their limits and therefore fire extinguishing systems that use gases such as carbon dioxide, inert gases or clean agents such as FM-200® and Novec™1230, which are especially appropriate for dealing with fires in electrical systems because they extinguish the fire quickly whilst not damaging the electrical systems or the compartment in which they are being discharged.

However, it is important to note that such fire extinguishing systems require maintenance to ensure they are fully operational and ready in event of a fire. ISO 14520-1:2015(E) assumes that these systems accidentally discharge and leak. 6.2.4.2 Contents indication: “Means shall be provided to indicate that each container is correctly charged.” Followed by “9.2.1.3 The storage container contents shall be checked at least every six months as follows. a) Liquefied gases: for halocarbon agents, if a container shows a loss of agent in quantity of more than 5 % or a loss of pressure (adjusted for temperature) of more than 10 %, it shall be refilled or replaced.”

Section 10.5.3.2.2. of the NFPA 850 states that the Maintenance and inspection of total flooding gaseous agent systems and interlocked equipment are critical. All systems at some time maybe called upon to operate in an emergency situation and may help in saving life and property. It is for this reason that knowledge must be had that the system can operate to its full potential.

Focused on continued advancement of safety technology, Coltraco have now developed the Permalevel® Multiplex, a fixed fire suppression monitoring system, designed for continuous contents verification. Permalevel® is designed to ensure that fire suppression systems are always fully operational and that no accidental discharge has occurred, which could affect the effectiveness of the overall fire protection system in the event of a fire. With guaranteed systems operations, adaptability for purpose, 24/7 remote access to the systems status, an uninterruptible power supply (UPS) and remote real-time monitoring, the Permalevel® offers the efficiency that is needed in a wind turbine. For regular inspection, the Portalevel® MAX is a handheld ultrasonic liquid level indicator, which can service a cylinder in 30 seconds (in contrast to 15 minutes by traditional manual weighing) with accuracy of up to 1.5mm off the true liquid level. Portalevel® MAX builds on Coltraco Ultrasonics’ 30 years’ experience in designing, manufacturing and supporting ultrasonic liquid level indicating equipment, in 108 Countries and numerous market sectors and environments. The development program was born out of the desire to further improve on Coltraco’s existing 8 designs and taking on board feedback and opinions of our customers.

Coltraco Ultrasonics provide smart Firetest® solutions which enable wind turbine owners and operators to improve their fire safety management and reduce the risks to human life, business continuity caused by any downtime and thus minimise risk to reputation by delivering a Safesite®.

How does the Portalevel® MAX enables its users to become industry leaders?

Incidences of fire on ships have been increasingly reported. In 2016, a couple who were travelling on the Estrella Amazonica tragically lost their lives after an uncontrolled fire broke out due to a lack of appropriate equipment and a failure to follow safety protocols. It’s this failure to ensure the safety of passengers which the Carnival Cruise line chose to mitigate by selecting Coltraco’s Portalevel® MAX.

Gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use, shown in the regulations that demand their upkeep e.g. IMO SOLAS FSS Ch5. 2.1.1.3. The systems are pressurised approximately 24-29 bars, higher than a standard cup of water which is 1bar. It’s accepted that these systems are not passive but dynamic, thus requiring monitoring. The traditional method requires turning the system off, dismantling and manually weighing each cylinder on industrial scales. Routine maintenance is liable to be overlooked because the crew is unqualified to test or insufficient attention is given by the owner of the system. It’s neglected to the peril of the lives of occupants of the ship and at the risk of crippling financial and reputational loss to the cruiseliner.

Innovative methods of inspecting leaking cylinders with ultrasonics, enables identification in under 30 seconds using Portalevel® with one person, instead of the traditional 15 minutes, with two people labouriously weighing. Using ultrasonic technology - to pinpoint the liquid level of suppressant agent in the cylinders of the extinguishing system- testing is quicker and easier.

The MAX Marine is designed primarily for maritime applications where either third party service companies or the vessels’ crew themselves inspect large fire suppression systems of up to 600 cylinders. The ease of operation in comparison to weighing, increases the ability of more regular and frequent checks, improving fire safety management onboard. Portalevel® MAX enables its users to go above and beyond minimal regulations compliance, thus becoming industry leaders.

Coltraco finds success in supplying the global shipping network with the assistance of international partners and ODAs, who provide local support to customers. Coltraco strive towards creating innovative and effective equipment to provide a level of safety that goes beyond regulations. Coltraco designs, manufactures and supports a world-leading range with a technological basis in ultrasonics.

How do you ensure the Safeship®?

Gaseous extinguishing systems protect important infrastructure against special hazards, fundamental for the safeguarding of critical facilities. A ship’s gaseous extinguishing system typically comprises between 200 and 600 cylinders each containing 45KG of CO2 under high 720 psi/ 49 bar pressure. (Other suppressant clean agents such as FM-200® and Novec™1230 are becoming more widely used.) One of the highest probabilities of discharge occurs during their maintenance. Some marine service companies estimate that 20% of a ship’s CO2 cylinders have discharged or partially leaked their contents at some point in their lifetime. Taking CO2 systems through as an example, although random checks may be suitable in some sectors, it is worth remembering that because the normal design concentration of CO2 of 34-72 v/v % is above the nearly immediate acute lethality level, these systems have an extremely narrow safety margin. As these systems work through oxygen dilution rather than the chemical disruption of the catalytic combustion chain (which is the case with other clean agents), insufficient oxygen levels during an accidental discharge may allow a situation to spiral out of hand. Yet although this poses high levels of risk to the service companies and the crew, because gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use and this is shown in the regulations that demand their upkeep.

The implementation of regulations through Safeship technologies ensure that the gaseous extinguishing systems are functional in the event of a fire. The regulations that currently govern gaseous extinguishing systems are the IMO SOLAS Fire Safety Systems (FSS) Code and the BS EN ISO 14520 standards.

IMO SOLAS & FSS Code Chapter 2.1.1.3 - “Means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers.”

Clean agent fire-fighting systems are guided by BS EN ISO 14520 Gaseous Fire Extinguishing Systems. BS EN ISO 14520 -1:2015(E) assumes that the execution of its standards is entrusted to people qualified and experienced in the specification, design, installation, commissioning, testing, approval, inspection, operation and maintenance of systems and equipment, and who can be expected to exercise a duty of care to avoid unnecessary release of extinguishant.

ISO 14520-1:2015(E) specifically states in 6.2.4.2 Contents Indication that - Means shall be provided to indicate that each container is correctly charged and in 9.2.1.1 At least annually, or more frequently as required by the authority, all systems shall be thoroughly inspected and tested for proper operation by competent personnel.

In ISO 14520-1:2015(E) 9.2.1.3 - The storage container contents shall be checked at least every six months as follows: a) Liquefied gases: for halocarbon agents, if a container shows a loss of agent in quantity of more than 5 % or a loss of pressure (adjusted for temperature) of more than 10 %, it shall be refilled or replaced. b) Non-liquefied gases: for inert gas agents, pressure is an indication of agent quantity. If a container shows a loss of agent quantity or a loss of pressure (adjusted for temperature) of more than 5 %, it shall be refilled or replaced.

The crew have a responsibility to implement the regulations via regular testing, which enabled through smart ultrasonic technology and IoT, should be done continuously to avoid negligence and unnecessary risk. Misunderstanding exists across parts of shipping industry regarding the application of a part of the IMO SOLAS FSS Code: the need for crew to test the contents of their CO2, FM-200® & NOVEC™ 1230 Gaseous Extinguishing Systems in between the periodic inspection, maintenance and certification intervals. These periodic inspections are conducted annually or biennially, and only by an Accredited Service Agent i.e. an external Marine Servicing Company. The reason IMO requires crew to test for contents in-between these is that the “ship sails alone” and “there is no such thing as a small fire at sea”; it must act as its own emergency fire service, differing to a land based asset. In order to create a Safeship® the crew must be in full understanding of the status their safety systems at all times and not just at the times of the inspections – achieved by continuous monitoring.

Gaseous extinguishing systems must be able to actuate, or release their gas, in the event of a fire. Given that the gaseous systems are designed specifically to the individual need of the vessel, and it is known that they leak, then a 5% loss of agent may mean that they would not fully extinguish the fire. These are pressurised systems, so the point of monthly checking for contents is to identify loss of contents through leakage or accidental discharge before they fall below their capacity to extinguish (technically described as: delivering their design concentration). Only having the annual inspection by accredited marine servicing companies is not enough – the crew must take responsibility for its own fire protection and inspecting the gaseous extinguishing systems. But what if there is leakage in between these monthly checks? With fewer, even lower-skilled crew and a greater dependence on autonomous machinery, the dependence on fire systems being checked from shore, let alone on the ship in person, will only become greater. Manual weighing is not only laborious, but also dangerous to the crew conducting the servicing. New technology allows ship owners and crews to help them both the spirit and letter of the regulation and thus know that their vessel is protected in the event of a fire.

Smart technology provides the crew and ship owners with ease of inspection and understanding their extinguishing systems. However, the crew will not be able to refill the gaseous extinguishing system, and instead must rely on notifying the marine servicing company when they arrive at a port, despite the fact that they may only be at the port for a very short amount of time. Due to time pressures, the risk of not being able to find a contractor in time to fill the cylinders in the event of leakage is one that could jeopardise the safety of the entire ship when it is time to set sail. Furthermore, it is well known that vessels are kept at the dock for a minimum amount of time, which reduces time for repairs and thus efficiency without compromise of safety is key. Continuously monitoring the cylinders with ultrasonic sensors that utilises IoT can avoid this, because the network contribution. Using IoT enables the advance notification of the crew and shore based services whilst at sea. Therefore, preparations to address the issues can be made prior to docking to ensure the issues are resolved given the minimum time they have. By having the ability to understand the contents’ level of their gaseous extinguishing systems whilst at sea, the crew are also able to comply and exceed the IMO SOLAS FSS and ISO 14520 regulations, whilst ensuring the Safeship®.

What is the future of watertight integrity testing?

As the main cause of vessel loss is sinking, the maintenance, testing and monitoring of watertight hatches, doors and multiple cable transits on vessels is essential. A watertight hatch cover is designed to prevent the passage of water in either direction under a head of water for which the surrounding structure is designed.  Many mariners may think hatches are robust, monolithic structures, thereby failing to appreciate the small tolerances on panel alignment and gasket compression. It is better to think of hatches as complex, finely-made structures, to be handled with care. All types of seals, experience dynamic stresses as part of their operational lifetime. For example, 4mm wear on the steel-to-steel contact is sufficient to damage rubber sealing gaskets beyond repair; 5mm sag along the cross-joint can cause a large gap between the compression bar and gasket. The importance of continually maintaining seal integrity should take a more prominent position in ship maintenance scheduling.

The existing regulations that state the need to ensue watertight integrity, are also part of the IMO SOLAS Code.

IMO SOLAS Reg II-1/13-1.1 – Openings in Watertight Bulkheads and Internal Decks in Cargo Ships - “Where penetrations of watertight bulkheads and internal decks are necessary for access, piping, ventilation, electrical cables, etc., arrangements are to be made to maintain the watertight integrity.”  

IMO SOLAS Reg II-1/21.3 – Periodical Operation and Inspection of Watertight Doors, etc., in Passenger Ships - “The watertight doors and all mechanisms and indicators connected therewith[sic] shall be periodically inspected at sea at least once a week.”

The future of watertight integrity testing is with continuous monitoring. A lack of proper servicing of seals can lead to deterioration which endanger the lives of the crew, vessel and cargo.  The large issue here is that ships are only tested before and after one or perhaps several journeys; yet a leak could occur at any point in between testing and continue unnoticed until the next inspection. A vessel generates its leak sites due to load states, sea states, wind states, and dynamic movement. The severity is amplified within a vessel structure constantly changing by varying sea, wind, load states, cargo types and dynamic stresses. There is a great deal of bending and deformation that naturally occurs in ships during travel. It was found that a comprehensive, autonomous continuous monitoring system for the watertight integrity of a ship’s cargo hatches, weathertight doors and other seals is possible to be developed. One that is capable of automatically detecting emerging leak sites, alerting officers and crew of the location and severity of the leak site and logging all data for future review. The developments in continuous monitoring technology being undertaken by Coltraco Ultrasonics will drive the industry towards ensuring that watertight integrity is never left to chance.

At sea, fire poses one of the biggest threats to ships

Could a cruise or ferry company afford to have a crippling financial, physical and damage to its reputation caused by a fire that could put the passengers, crew and vessel in danger? The correct answer for everybody involved is “No.”

Fires on board ships can be devastating, to passengers, crew and vessel thus fire safety standards on board is something a passenger-carrying vessel cannot afford to slip. Part of safety standards on board a cruise ship is the maintenance of gaseous fire extinguishing installations, which may be compromised by the holes in the regulations.

It is understood that a need for practical cost-efficient solutions to safety issues is paramount. However, maintaining high standards of fire safety practice does not have to be expensive or time consuming, according to fire safety expert Coltraco Ultrasonics. You need to check out the range of monitoring devices such as ultrasonic level indicator.

Coltraco Ultrasonics to provide easy and long lasting solutions that are suitable for varying budgets. Regulations should be responded to with a rigorous attitude, to go above and beyond the rules in order to provide security of life and infrastructure. For example, installations must be maintained so that they can provide the protection that they are intended for.

Reviewing on this factor of safety equipment; “this is a call to the industry to be aware of the problem and the action to be taken.” At sea, fire poses one of the biggest threats to ships. Sailing alone and at sea throughout the year and without the ability to call upon the emergency services, as a land-based asset might, the danger is shown in the statistics.

Although serious fires on cruise ships are ferries are very rare, a recent study published by the Finnish Transport Safety Agency showed that almost 800 fires occurred in European waters between 2004-2014 on all types of vessels. Of these some 10% of these were classed as serious. Further to this, around 200 of these incidents required external support to help deal with the fire. In some of these cases, the fire suppression installations may not have been at their full capacity, which led to uncontrollable fires, Coltraco said.

Test your fire suppression systems – before its too late

The easy to use Portalevel® MAX uses ultrasonic technology to pinpoint the liquid level of suppressant agent in the cylinders of the extinguishing system which makes testing quicker and easier. Liquid level identification takes just 30 seconds, needing only one person. (Compared to traditional manual weighing taking two people an average of 15 minutes per cylinder.) Combined with the Portalevel® MAX, the Portasteele® CALCULATOR is the first of its kind app, that converts the liquid level height of C02, NOVEC™ 1230 and FM-200® found my Portalevel® MAX into the agent weight/mass. Crucially, these results can be recorded and downloaded for value added service reports.

Smart Technology delivers the Safesite

To create the Safesite®, more faciliites are moving to increasing sensor remote monitoring 24/7, 365. Fire alarms are largely linked up but there is a gap in the fire extinguishing systems which actually suppress the fire event. Now is the time to introduce smart technology. Permalevel® MULTIPLEX is designed for just this reason to protect aluminium facilities and their personnel.

Using smart ultrasonic technology, Permalevel® MULTIPLEX continuously monitors fixed fire extinguishing systems for leaking agents, 24/7, 365 days a year. With guaranteed systems operations, adaptability for purpose, 24/7 remote access to the systems status, an interruptible power supply and remote real-time monitoring, Permalevel® MULTIPLEX offers the efficiency that is now a requirement for encompassing protection.

What is the Smart Ship to Coltraco Ultrasonics?

Through ongoing technology advancements, ship owners can protect their crew, vessels and cargo with smart Safeship® technologies. We can better achieve the Smart Ship, implement existing regulations, and strengthen new ones, by introducing more sensor monitoring technologies which will be linked by IoT. The application of the IoT and ultrasound allows the Smart Ship to be achieved here and now whilst research and development presents future opportunities. Continuous monitoring solutions benefit the crew: by being easy to operate, quick, accurate and better than traditional monitoring techniques, means the likelihood of their use and thus protection is much higher. Whilst regulations can sometimes be said to drive up costs in the short term, their longer-term impact is designed to save time, costs and improve the industry. Owners, managers and operators in particular must strive towards the Safeship®: holistic protection of their fleet.

The Smart Ship can be a Safe Ship by implementing new technology such as that developed by Coltraco Ultrasonics. The neglect of continuous monitoring of the fundamental protection provided by the gaseous extinguishing systems and watertight integrity imperils the lives of ship’s crews and occupants and at the risk of crippling financial and reputational loss to the tanker owner. Continuously monitoring gaseous extinguishing systems and watertight integrity with the aid of IoT raises awareness of the safety critical need to implement and exceed regulations, through continuous inspection.

Coltraco Ultrasonics understand that through the developments and current emphasis on IoT we are closer to reaching the Smart Ship which is bringing greater awareness for the shipping industry to improve. Due to this, future regulations could be strengthened by the inclusion of constant monitoring and IoT developments to allow for the better implementation of the Smart Ship which will be a Safe Ship. IoT and big data offer great benefits to enable implementation and potential change in the regulations.

Ultrasonic Leak Sensors can Assist in find holes and leaks for Cargo Safety

Spilling vessels are the most serious hazard to the economy as whatever else. A vehicle vessel can pass on items worth billions of dollars on a singular trip. Imagine the incident that would happen if a vehicle transport passing on each one of these stock transforms or sinks. Whatever may be the reason of the fiasco, the cause would be none other than the proximity of holes in the vessel's body. Since the pontoon's solitary medium of travel is the ocean, the most anomalous measure of stickiness on the docks and when the vessel is cruising can realize rusting paying little heed to the way that a touch of its iron body is revealed.

There is no ending to rust and openings in a watercraft's body, especially a vehicle vessel's body. As the colossal and overpowering stock are stacked and purged in the payload holds, the scratching and thumping causes engravings and chips off the pontoon's cautious paint. Once the body or the paint is hurt in any way, the advancement of rust gets the chance to be beyond question and from now on, a hole. Since there is no stopping to it, there is a way to deal with guard a watercraft from further mischief and that is filling the openings when they appear. Holes must be filled once they are found by the technique for hatch cover maintenance and watertight integrity testing with ultrasound.

Crevices can appear in most of the astounding spots inside a watercraft's body. Finding them can be amazingly troublesome and it can be incomprehensible with no strong instruments. The fundamental mechanical assembly that is really valuable in finding the openings in the vessel's body and brood spreads is the ultrasonic contraption which is flexible and astoundingly exact in its working.

The generator which makes the ultrasonic waves is kept inside the watercraft's payload holds or whatever other piece of the body to be striven for openings and breaks. As it starts making the beat, the ultrasonic waves escape from the spilling regions and the openings and are

gotten by the authority. From now on the territory of the hole is immediately found.

The most ideal approach to save the economy from being choked in the seas and to save the ocean business from getting a loathsome name is the reliable watertight compartment doors testing of each watercraft. As these tests are coordinated all the time by the pontoon's staff, it's completely unimaginable a break can go undetected and make threat the watercraft's security as it sails out on the immeasurable seas and oceans of the world.

Portalevel® MAX builds on Coltraco Ultrasonics’ 30 years’ experience in designing, manufacturing and supporting ultrasonic liquid level indicating equipment, in 108 Countries and numerous market sectors and environments. The development program was born out of the desire to further improve on Coltraco’s existing 8 designs and taking on board feedback and opinions of our customers.

Coltraco Ultrasonics provide smart Firetest® solutions which enable wind turbine owners and operators to improve their fire safety management and reduce the risks to human life, business continuity caused by any downtime and thus minimise risk to reputation by delivering a Safesite®.

What is the Portasteele® Calculator?

The assumptions in the installation and maintenance of gaseous extinguishing systems is that they are highly pressurised but risk leaking and discharging. ISO 14520-1:2015 aim to identify their leak identification at an interval of at least every 6 months.  Traditional methods of weighing are laborious and dangerous, taking 15 minutes and two people to weigh a cylinder. To combat this, Coltraco Ultrasonics developed the Portalevel® MAX, an 8th generation ultrasonic liquid level indicator, for identifying the contents of CO2, FM200, NOVEC 1230, FE-13, FE-25 & FE-36, Halon and a variety of similar liquid gaseous fire suppression agents, in just 30 seconds. However these liquid level readings were not weight measurements which is required and does not take into account the effects of temperature.

The Portasteele® CALCULATOR is an advanced calculator application, that converts the liquid level height of C02, NOVEC™ 1230 and FM-200® liquefied gaseous extinguishant agent readings taken on an Portalevel® MAX into the agent weight/mass.  The PortasteeleÒ CALCULATOR is the first in the world to provide agent weight readings without physically weighing the fire suppression cylinders to comply with fire safety regulations. This is a safer, more efficient and cost saving method to service fire cylinders. The PortasteeleÒ CALCULATOR is based on a stand-alone 7” tablet computer which makes calculations in real time and logs the results, allowing the software to be used immediately in the field.

By replacing the use of manual calculation and formulae, Portasteele® CALCULATOR makes the whole process of fire suppression system servicing simple and effective. The technological innovation ensures an entirely user friendly and industry leading device.
The Portasteele® is the first in the world to provide agent weight readings without physically weighing the fire suppression cylinders to comply with fire safety regulations. Coltraco Ultrasonics are the only company able to identify clean agent weight from liquid level readings – allowing a servicing company to go above and beyond regulations.

Coltraco Ultrasonics are the only company in the world who can provide true contents indication through the Portasteele® CALCULATOR. The calculation provided takes into account all environmental factors without requiring an overwhelming excess of information from the user and can provide highly accurate results across the broad range of cylinder types available in the fire protection sector. The Portasteele® CALCULATOR is the only device of its kind on the market. The Portasteele® CALCULATOR accurately converts the liquid level into agent weight and takes into account temperature variation by compensating for it using density changes. The final result is weight, which is unaffected by temperature – something that cannot be achieved by a liquid level indicator alone.

2.1 WHAT ARE GASEOUS EXTINGUISHING SYSTEMS AND WHY DO THEY LEAK?

To address the issue of fire in ships, which is one of the top reasons for vessel loss, the authors of this paper applied their expertise to an important problem in gaseous extinguishing systems: they leak. Gaseous extinguishing systems protect important infrastructure against special hazards, fundamental for the safeguarding of critical facilities. A ship’s gaseous extinguishing system typically comprises between 200 and 600 cylinders each containing 45KG of CO2 under high 720 psi/ 49 bar pressure. (Other suppressant clean agents such as FM-200® and Novec™1230 are becoming more widely used.) One of the highest probabilities of discharge occurs during their maintenance. Some marine service companies estimate that 20% of a ship’s CO2 cylinders have discharged or partially leaked their contents at some point in their lifetime. Taking CO2 systems through as an example, although random checks may be suitable in some sectors, it is worth remembering that because the normal design concentration of CO2 of 34-72 v/v % is above the nearly immediate acute lethality level, these systems have an extremely narrow safety margin. As these systems work through oxygen dilution rather than the chemical disruption of the catalytic combustion chain (which is the case with other clean agents), insufficient oxygen levels during an accidental discharge may allow a situation to spiral out of hand. Yet although this poses high levels of risk to the service companies and the crew, because gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use and this is shown in the regulations that demand their upkeep.

2.2 WHAT ARE THE REGULATIONS THAT GOVERN GASEOUS EXTINGUISHING SYSTEMS?

The implementation of regulations through Safeship technologies ensure that the gaseous extinguishing systems are functional in the event of a fire. The regulations that currently govern gaseous extinguishing systems are the IMO SOLAS Fire Safety Systems (FSS) Code and the BS EN ISO 14520 standards.

IMO SOLAS & FSS Code Chapter 2.1.1.3 - “Means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers.”

Clean agent fire-fighting systems are guided by BS EN ISO 14520 Gaseous Fire Extinguishing Systems. BS EN ISO 14520 -1:2015(E) assumes that the execution of its standards is entrusted to people qualified and experienced in the specification, design, installation, commissioning, testing, approval, inspection, operation and maintenance of systems and equipment, and who can be expected to exercise a duty of care to avoid unnecessary release of extinguishant.

ISO 14520-1:2015(E) specifically states in 6.2.4.2 Contents Indication that - Means shall be provided to indicate that each container is correctly charged and in 9.2.1.1 At least annually, or more frequently as required by the authority, all systems shall be thoroughly inspected and tested for proper operation by competent personnel.

In ISO 14520-1:2015(E) 9.2.1.3 - The storage container contents shall be checked at least every six months as follows: a) Liquefied gases: for halocarbon agents, if a container shows a loss of agent in quantity of more than 5 % or a loss of pressure (adjusted for temperature) of more than 10 %, it shall be refilled or replaced. b) Non-liquefied gases: for inert gas agents, pressure is an indication of agent quantity. If a container shows a loss of agent quantity or a loss of pressure (adjusted for temperature) of more than 5 %, it shall be refilled or replaced.

How can ultrasonic technology assist safety in the mining industry?

Fires and explosions pose a constant threat to the safety of miners and to the productive capacity of mines. Mine fires and explosions traditionally have ranked among the most devastating industrial disasters. The prevention and control of fire and explosion in mines is fundamental. On a mine site, fire hazards may occur in and around process plants, underground conveyors, static and mobile plants, draglines, workshops, substations, monitored control rooms and switch rooms. All mines have highly expensive and mission critical equipment that typically operate day and night under extreme hostile conditions, in vast, remote and difficult to access environments, especially on underground equipment. In many cases non-gaseous and gaseous fire suppression systems are the preferred systems installed to protect the high value assets, safeguard operators and processes so as to guarantee business continuity. However, it can be argued that the competitive nature of the free market places great pressure on the fire industry to deliver systems which minimally comply with, rather than exceed, the regulations. Too often fire protection is seen as a cost - not a vital investment for business continuity. High value assets such as critical mining infrastructure, may have catastrophic results in the event of downtime or shutdown due to fire. The risk far exceeds the risk of choosing minimal compliance, instead of advanced real-time monitoring systems. The cost or damage to reputational integrity as a result of this downtime far exceeds the cost of integrating a real-time monitoring system.

CASE STUDY: ultrasonic technology offers quick, safe & reliable solutions

The importance of ultrasonic technology to the mining industry has been demonstrated by its use thus far. NRG Energy have been using the Portalevel™ Max since 2015 at the Morgan Town Generation Plant in Morgantown, Charles County in Maryland, US. The Morgan Town Plant is a coal powered power station based in Maryland. NRG own the USA’s largest and more diverse power generation competitive portfolio. NRG are dedicated to smart and reliable energy sourcing, and emission reductions although coal is a significant part of the electricity generation. The Portalevel™ Max is an example of the technologically advanced techniques that the company are implementing to lead the way in safe and sustainable coal sourcing. After witnessing fire service experts undertaking ultrasonic liquid level indication in just minutes, they were keen to change from their previous method of weighing. As a safety critical asset, the Morgan Town Plant saw the necessity in investing into their fire safety. This was the same as at the Vales Point Power Station at Delta, Australia. The power station is at the southern end of lake Macquarie. This power station was built in the 1960’s as a four-unit station, but now operates two 660 MW generating units. The Power Station is owned and operated by Power International, with the capacity of around 1,320 megawatts, providing 24 hours electricity. In 2013 they bought Coltraco Ultrasonics’ Portagauge® 3 thickness gauge for testing normal structure and stainless steel.

How to inspect liquefied gaseous systems with ease and speed

Utilising ultrasound technology, Coltraco Ultrasonics have been manufacturing a range of ultrasonic portable liquid level indicators known as the Portalevel®. The Portalevel® MAX is the latest generation of the Portalevel® line and is designed to provide enhanced speed, operation and performance, especially for high intensity testing requirements and works brilliantly for testing cylinder contents of fixed fire extinguishing systems like CO2, NOVEC™ 1230, FM-200™ and other clean agents. The device has UL, RINA and ABS Type Approval, building further on their history of over 27 years manufacturing this equipment and showcasing the commitment to the marine and shipping industry. The Coltraco Safesite™ technology suite includes Portalevel ® MAX; a “world leading handheld ultrasonic liquid level indicator for testing most common extinguishing agents”; the Portasteele™ Calculator tablet based app converting the liquid level into agent weight/mass with ease, simplicity and ability to log the results; and the Permalevel ® Multiplex for 24/7, 365 autonomous, continuous monitoring of fire suppression systems, with remote relay, remote diagnostics and alarm capability to alert in case of agent leak/discharge.

What is the Portascanner® 520?

The Portascanner® 520 is an Ultrasonic Room Integrity Tester which accurately and efficiently complements door fan testing. The simple system locates a leak site via visual and audible readings and identifying its extent with a definitive numerical result. The 520 can test leaks as small as 0.06mm.

The Portascanner® 520 is the most accurate unit of its type, locating a leak site via visual ad audible readings and suppling a definitive numerical results. The unit can test leaks as small as 0.06mm, which is unparalleled accuracy compared to the puffer test technology which is a purely visual inspection. The smoke puffer tests also involves evacuating a building or room whereas the Portascanner® 520 is completely clean and damage free. The advantages of being able to accurately detect the exact leak locations and size are self-evident when considered alongside the importance of reaching Peak Pressure for clean agent fire suppression to be effective. In a case where there is too much leakage in a room (and thus insufficient Hold Time), the Portascanner® is an unrivalled ideal for the rapid and accurate identification of these sites so that they can be sealed. It is the first of its kind, intuitive to use, non-invasive, and consequently, is of immediate use to the Fire Industry.

It is lightweight, fast and easy to use, allowing leak site detection to increase its operational efficiency and speed to a degree that has never been seen thus far in the Fire Industry. This method increases safety, by allowing the user unparalleled leak detection. This leads to the user having superior control of the agent hold time and peak pressure, effectively guaranteeing the identification and extent of leak sites. The unit is also lightweight and hand-held, weighing only 419 grams. The unit can also be used as a pre-surveying inspection tool, prior to bringing in full door fan test equipment.

Benefits of the Portasonic®

There are a number of issues to be considered in regard to maintenance such as corrosion, flow rate and obstructions that may adversely affect the effectiveness of a fire sprinkler system.  The NFPA has a concern that corrosion can cause a sprinkler system to fail due to blockages and failed sprinkler heads. Trapped water from hydrostatic testing, combined with humid air supplied constantly by the air compressor creates the perfect conditions for corrosion. The NFPA states that 73% of dry systems have significant corrosion issues. According to the NFPA, corrosion can cause inhole leaks, temporary shutdowns, loss of property and personal injury if the sprinklers fail to release. With some systems between 30-40 years old, weakening and corrosion is a major issue. One of the problems that can come from a lack of maintenance and corrosion are nozzle blockages. Nozzle blockages are a serious safety risk because they have serious impact on the functionality of the system which thus increases the risk of an uncontrollable fire. The HSE have reported that no matter what material the pipework is constructed in, the impact will still occur. When tested with the Hazen-Williams formula, steels performance can drop by over 50% for pipes that were in service between 4 and 40 years.  One method of flow measurement is wet testing, where water is sprayed through to prove its compliance, yet this can cause deposits, contamination and blockages. An example of a pipe with VdS Class III corrosion; Considerable corrosion and deposits the complete pipe array or parts of it must be replaced, is shown below.

Portasonic® is easy to use and is proven to reduce maintenance time and costs. It can also be used for testing fire hydrants. Sprinkler heads are spaced, so that if one or more operate there is always sufficient flow of water. The flow is calculated so that there is always enough to control a fire taking into account the size and construction of the building and the goods stored in it or its use. Accurate flow data provides the chance to make energy saving measures by fine tuning the systems. The Portasonic can measure this through self-adapting proprietary signal quality tracking, allowing the device to automatically optimally adapt to the pipe material and flow profile in both directions.

This ultrasonic flow meter Ideal for the measurement of flows in clean, non-aerated fluids such as water, water/ glycol and oils in full pipes from ½” to 180” (12 to 4570 mm) diameter can be measured and the ultrasonic signal penetrates all common metal and plastic pipe materials.

Key Features of Ultrasonic Flow Meter

  • Accurate flow measurement from outside of a pipe with clamp-on sensor
  • Measures, totalizes and transmits flow in both directions
  • Simple set-up and ease of operation with digital processing
  • Larges display with user-friendly calibration menu

Why must we continuously monitor gaseous suppression systems?

Continuous monitoring is no longer an option; it is essential for the protection against special hazards in critical infrastructure. Clean agents are designed to operate in limited spaces where there is a need for speed of suppression given the asset risk and where the space is occupied by people. They deliver the infrastructural resilience our advanced society requires. The assumptions in the installation, commissioning and maintenance of gaseous extinguishing systems is that they are highly pressurised but risk leaking and discharging. ISO 14520 specifically guides our industry as to these risks; In 9.2.1.3 The storage container contents shall be checked at least every six months as follows. : a) Liquefied gases: for halocarbon agents, if a container shows a loss of agent in quantity of more than 5 % or a loss of pressure (adjusted for temperature) of more than 10 %, it shall be refilled or replaced. b) Non-liquefied gases: for inert gas agents, pressure is an indication of agent quantity. If a container shows a loss of agent quantity or a loss of pressure (adjusted for temperature) of more than 5 %, it shall be refilled or replaced. Therefore, at a standards level it is known that gaseous systems can become ineffective through accidental discharge and leakage and thus they do not serve to protect the critical infrastructure in such a case. To know the contents, you need to monitor it, and checking it every 6 months is not monitoring it.

Should we not just constantly monitor all of them and be in full compliance to the regulations and the risks that are so clearly described in our own core standards? If it is known and accepted that these are dynamic systems that are prone to leaking, but they are expected to deliver resilience and protection, then why are they left unattended for 6 months of the year? We would not do the same to an alarm system without monitoring it 24/7, so why are we not monitoring gaseous extinguishing systems? Let us apply 21st century science to a 100 year old issue and be done with it. A dynamic system needs monitoring. The neglect of continuous monitoring of the fundamental protection provided by the gaseous extinguishing systems is to the peril of the lives of occupants of the premises and at the risk of crippling financial loss to the facility comprising the critical infrastructure. To ensure that dynamic gaseous systems are protecting critical infrastructure in a safe and diligent manner, 6 monthly monitoring and maintenance is no longer enough. There is a call for continuous monitoring and this is something that cannot wait any more.

Room Integrity and Compartmentation

Room Integrity is often an overlooked aspect of a clean agent installation whereby it is required that the concentration of the clean agent meets the sufficient “Hold Time” when discharged in a room in order to properly extinguish fires. Achieving this “Hold Time” is largely dependent on the overall leakage in the room otherwise referred to as the “Equivalent Leakage Area” or ELA in the industry. The most common and widely accepted way of determining whether the enclosure achieves the sufficient “Hold Time” for the agent is by carrying a Door Fan Test (DFT). This involves pressurising and depressurising the enclosure to check if it achieves the pass rate and if the enclosure fails the test, the presence of leaks are the common contributors to this failure. The industry introduces various methods to identify these leaks which are then patched up before the DFT is being conducted again. What is an often-neglected fact is that as a buildings age or their internal use is changed, leak sites will begin to develop. If the gas cannot be held in the confined space on discharge during a fire event, the probability of its suppression diminishes in proportion to the size of the leak sites. Clean agents are designed to operate in limited spaces where there is a need for speed of suppression given the asset risk and where the space is occupied by people. They must be easily maintained in-situ, non-flammable and non-toxic. They must comply with ISO 14520 and NFPA 2001 standards demanding fast discharge in 10 seconds and fire extinguishing within 30 seconds, delivering confidence to the operator that it delivers “best fire safety practise”.

Despite DFT being a reliable method to determine the “hold time”, methods to locate the leak sites themselves are inaccurate such as the use of smoke pencils or draught testing using the back of a hand. The limitations of the DFT often lie in the fact that the leakage areas are only identified during installation of the clean agent system and make no acknowledgement to the fact that additional leak sites may develop throughout the lifetime of a building.

In the event of fire, a pencil sized hole between compartments size 6m x 6m x 3m would take just 4 minutes before a person would not be able to see their hand due to smoke. If this compartment was a fire escape, there could be a severe threat to life if people cannot escape. Thus it is clear to see why the maintenance of the integrity of the compartments is essential to genuinely aid the safety to human life. As building age or their internal use is changed leak sites develop and the threat to people becomes high Coltraco Ultrasonics have provided a smart solution for quick and easy assurance of compartmentation and leak detection. The proprietary device known as the Portascanner® 520 ultrasonic leak detector uses ultrasonic technology to not only pinpoint precise leak locations, but to determine their leak apertures as small as 0.06mm with a tolerance of +/-0.02mm, and is by far the most mathematically proven accurate device for this function.

“Ships sink; fires happen”

Addressing these two main causes of vessel loss are critical, especially when all owners and managers are seeking to reduce risk, cut costs, surge on safety and protect seafarer welfare. Gaseous extinguishing systems are highly pressurised, the risk of leaking and discharging is accepted as part of their use, shown in the regulations that demand their upkeep e.g. IMO SOLAS FSS Ch5. 2.1.1.3. The systems are pressurised approximately 24-29 bars, higher than a standard cup of water which is 1bar. It’s accepted that these systems are not passive but dynamic, thus requiring monitoring. The traditional method requires turning the system off, dismantling and manually weighing each cylinder on industrial scales. Routine maintenance is liable to be overlooked because the crew is unqualified to test or insufficient attention is given by the owner of the system. It’s neglected to the peril of the lives of occupants of the ship and at the risk of crippling financial and reputational loss to the owners.

The Portalevel® MAX Marine is designed primarily for maritime applications where either third party service companies or the vessels’ crew themselves, inspect large fire suppression systems of up to 600 cylinders. Innovative methods of inspecting leaking cylinders with ultrasonics, enables identification in under 30 seconds using Portalevel® MAX Marine with one person, instead of the traditional 15 minutes, with two people labouriously shutting down the system, dismantling the cylinders and weighing them. Using ultrasonic technology - to pinpoint the liquid level of suppressant agent in the cylinders of the extinguishing system - testing is quicker and easier. The ease of operation in comparison to weighing, increases the ability of more regular and frequent checks, improving fire safety management onboard. Portalevel® MAX enables its users to go above and beyond minimal regulations compliance, thus becoming industry leaders. Combined with the Portasteele® Calculator, the weight can be found in just 30 seconds more. It is an advanced calculator application, that converts the liquid level height of C02, NOVEC™ 1230 or FM-200® liquefied gaseous extinguishant agent readings taken on the Portalevel® into the agent weight/mass. There is no other similar alternative to weighing available on the market. Furthermore, the Portasteele® can convert an expected agent weight back to the required liquid level allowing users to anticipate where the level should be. This method also enables recording and downloading of the data, adding value to servicing reports and improving the safety management system for a auditable data trail.

Provide consistent and reliable safety by working with Coltraco Ultrasonics

Too often in the fire industry it feels like the certification is driving the maintenance, with its insurance consequence for the asset owner and service revenue for the contractor, rather than maintenance [for safety sake] driving its consequential certification. The ‘ungoverned space’ is the area in the fire industry where either the regulations or the protecting systems of the critical infrastructure are not effectively providing consistent and reliable safety.

People expect, and rightfully so, that in the event of a fire the extinguishing systems would be in full working order to do just that – extinguish. Given that the gaseous systems are designed specifically to the individual need of that room, building e.t.c, then a leak sites in the room could meant that the comparted area couldn’t withhold the fire. The likelihood of the gaseous system effectively extinguishing the fire gets lower and lower as the protected area becomes larger than the size that the extinguishing system was designed for. This is not a game of chance. The lives of people depend upon it.

Although many in the fire industry work towards meeting better standards, in their experience, Coltraco have numerous concerning anecdotes of non-compliance: systems portrayed and installed by contractors as NOVEC™ 1230 but filled with sand or water… room integrity testing with questionable results and with the room integrity remaining un-monitored after testing.

Technology now exists to improve the reliability of fire suppression systems that affects the safety of all who inhabits the building it protects in an event of fire. Regulations which often govern the quality of fire safety systems installed should hence reflect the latest advancement of technological innovations in its industry in order to uphold fire safety to its highest standards.

Testing the liquefied gaseous extinguishing systems (commonly CO2, sometimes FM-200® or Novec®1230) and also the room integrity into which they are situated, will create a holistic approach to solving the problem of the Ungoverned Space. In order to comply with regulations outlined in the NFPA 2001 and the ISO 14520, regular room integrity tests have to be performed on rooms wanting to install Clean Agent Fire Suppression Systems, in order to ensure the continued effectiveness of non-sprinkler fire suppression

Why understand and maintain fixed fire extinguishing systems?

The catastrophic consequences of fires on board Ro-Ro ships in the last decade, particularly on-board the “Norman Atlantic” in December 2013 and the “Sorrento” in April 2015, have pushed this issue into the limelight. They have encouraged studies from internationally acclaimed bodies such as the International Union of Marine Insurers (IUMI) and DNV GL. These studies confirm that the risk of fire is twice as great on Ro-Ro boats than on many other cargo and passenger vessels. Fire remains the number one cause for port state control detaining ships.  Consequently, the maintenance and proper understanding of a vessel’s fixed fire extinguishing (FFE) systems is critical. These boats, as with any vessel at sea, must act as their own fire-rescue system and be able to tackle on-ship fires in a safe, efficient and self-contained manner. As such, proper understanding and maintenance of FFE are of crucial importance, not just for cargo security and reduced insurance claims, but most fundamentally to protect human life through safe-ship practice.

The FFE systems on-board Ro-Ro vessels typically include CO2 gas cylinders for fire suppression. These large gas cylinders are stored under pressure, and consequently are subject to risk of leakage or accidental discharge; any small change in pressure of a gas cylinder can result in pressure falling below the point at which fire suppression would be effective. Currently, to ensure the effectiveness of these systems and abide by legal requirements, periodic inspections are conducted annually or biennially by an Accredited Service Agent i.e. an external Marine Servicing Company. However, the IMO SOLAS FSS Code also requires inspection of cylinders in between these periodical tests by the vessel’s own onboard crew.

Typical methods for on-ship regular cylinder inspection primarily consists of trained professionals weighing the chosen cylinder, to assess if there has been weight loss due to gas leakage. However, although this method is widely used, it is ultimately unsafe practice, requiring constant handling of tanks in a delicate, high-pressure state, usually at 720psi or approx.50 bar. To tackle this issue, technological advances have been made to create portable ultrasonic liquid level indicators which serve as liquid gaseous inspection equipment. Coltraco Ultrasonics is one such company providing safe, simple, non-invasive monitoring equipment that facilitates regular inspection of FFE gaseous systems. Through use of Ultrasonic Technology, these products are able to accurately and quickly assess the liquid level of CO2 or clean agent (commonly FM-200® or NOVEC™ 1230) suppression systems, in order to identify leakage or accidental discharge.

Benefits of the Portascanner® WATERTIGHT

Failure of the hatch-covers can cause damage to the cargo, loss of vessel stability and ultimately, loss of the vessel. Hatches must meet the SOLAS Convention, the Load Line Convention, classification society rules and IMO and ILO Guidelines. Watertight (WT) hatch covers prevent water ingress and cargo damage, preventing the possible loss of stability. Watertight integrity can also prevent seawater spray, which combined with air, may cause significant corrosion of the vessel structure and consequentially a reduction in strength. Therefore, hatches are fitted to ships to maintain watertight integrity and protect the crew, ship and cargo. In the forward 25% of the vessel, watertight integrity is particularly important as this is where sea loads are at their highest.

Most classification societies and P&I Clubs now recommend ultrasound which can be done in any weather states and when the ship is loaded. For example, UK P&I Club, Loss Prevention Department published updated information from the Carefully to Carry Commitment in 2002 about “testing weather-tight integrity of dry cargo vessels’ hatchcovers” identifying the ultrasonic test as best practice. IACS requires anyone carrying out a survey to be qualified but unlike most manufacturers, Coltraco manufactures Portascanner® WATERTIGHT, whose readings cannot include ambient noise. It is always recommended to conduct one test when the hold is empty and another when loading is completed, as this can reveal leaks caused by hogging or sagging. Ultrasonic leak detectors must be class type approved. The Portascanner® Watertight hatch cover testercheck the leaks and watertight integrity of hatch covers, accurately.

How does the Portascaner® Watertight work?

  • Connect the Rod and Headphones to the Receiver and place the Generator into the compartment to be tested.
  • Fix the Generator by the magnet to any metallic surface not far from the seal being inspected.
  •  Switch the Generator ‘Onʼ and all the readings will dramatically increase.
  • Leaving the cover of the seal being tested open and check around the seal to ensure a strong signal is being received at all points.
  • The compartment is then closed and the inspection of the seal begins.
  • If there is a leak or area of weak seal compression readings will increase.
  • By moving the Sensor to where the signal is strongest, the operator can identify the exact location and extent of any leak site and steps can be taken to fix this issue.

What is the Safeship® initiative?

Coltraco Ultrasonics implemented the Safeship® initiative, to promote protecting critical infrastructure at sea. The two main causes of vessel loss are sinking and fire. A lack of proper servicing of watertight and weathertight seals can lead to deterioration which can endanger the ship, cargo and lives of the crew through flooding and the potential of capsizing. Secondly, bad industry practice is unacceptable when fire risk may have catastrophic results due to risk to life, downtime in operation due to ship safety and repair work and incalculable reputational damage. The crew, cargo and vessel must be protected when at sea because it is it’s own fire brigade without accessibility to typical emergency services.

As a result, Coltraco designed the FLEETSAFE™: a package of innovative safety tools to combat the above and comply with regulations

  • an ultrasonic watertight integrity tester
  • an ultrasonic thickness gauge
  • a bearing indicator
  • an ultrasonic liquid level indicator
  • a calculator which converts liquid level readings to weight.

With this package the hatch-covers, doors, MCTs, compartments, pipework, hulls, bulkheads, rotating machinery, pumps, sprinkler systems and gaseous extinguishing installations are protected. The package is based on integrity, from design, through to life-time support, and is accurate, reliable and easy to use for any crew members.

To promote the Safeship® Coltraco Ultrasonics have been raising safety awareness and gaining recognition by winning and being nominated for several awards. In 2017 Coltraco won the Seatrade Cruise Award for Supplier of the Year and was nominated for the IHS Markit Safety at Sea Award 2017. Coltraco were also invited to speak at 16 conferences in 2017 to raise safety awareness and to educate, including at the International Maritime Organization, Royal Institution of Naval Architects Smart Ships Conference, IMPA London, Marine Maintenance World Expo and Pacific Sydney. Coltraco Ultrasonics speak at these events to raise their goal of holistic ship safety, in the form of the Safeship®.

The Safeship® initiative has also achieved recognition through engagement in association work such as the Society of Maritime Industries, at the House of Commons in Parliament, Maritime London and the International Maritime Industries Forum seminars and the UK Chamber of Shipping’s Safety Culture Working Group.
Through initiating the Safeship® Coltraco have contributed to safety at sea by building the FLEETSAFE™ capability that can be used easily and safely by the crew and in routine maintenance of the vessel Safety Management System (SMS). This can be in-between the statutory annual maintenance and certification intervals provided by shore-based contractors.

Increase Your Efficiency and Safety With The Portalevel® Max INDUSTRIAL

The desire to live longer and healthier is a pillar of modern life. Hence the demand for healthcare data, advanced therapies and ever quicker reacting cures in the pharmaceutical industry is so high. The UK is at the forefront of the global pharma sector. Health is a crucially important social and economic asset, and in the past 60 years, innovation and technology have driven huge improvements in global health. With the advances in knowledge comes the advances in manufacturing, with pharmaceutical companies manufacturing six times the average company in the UK. The scale of demand and the free market forces the manufacturing process to become smarter. One way to increase efficiencies is to improve the safety and maintenance of plants. Coltraco Ultrasonics are proud to be assisting British companies in the production of life changing medicine.

A British pharmaceutical company - one of the largest in the world - approached Coltraco for an innovative solution to aid their manufacturing process. Coltraco received a request from one of their manufacturing plants in Ireland, which produces active ingredients that are used in drugs to treat cancer, Parkinsons and Depression. At this plant, a mix of ammonia and water is delivered to the site in Intermediate Bulk Containers (IBCs): reusable storage tanks which commonly carry circa 1,040 litres. This ammonia is required at the pharmaceutical plant to breakdown manufacturing by-products before they are then safely incinerated.

Previously, the company had been monitoring the ammonia contents through a physical dip stick measurement on the tank, because of a lack of confidence in the internal IBC monitoring systems. However, the fumes given off by ammonia are irritating and corrosive, and can cause burning to the nose, throat and respiratory tract which poses a severe health risk for the engineers. Opening the top valve for the physical dip stick measurement also creates risk of contamination to the ammonia. For this reason, the pharmaceutical company asked Coltraco to deliver a new way to non-invasively monitor the contents within the IBCs.

A Coltraco Engineer visited the site to conduct technology suitability trials. A survey of several of the IBCs was conducted, and it was noted that some of the containers were partially full or fully empty. From this, the Engineer determined the general range for a full and empty state across 7 of the IBCs (as shown in the table below). Trials conducted by the Engineer indicated that Coltraco has the real opportunity to provide a solution for this application. Because of the flexibility and adaptability of Coltraco Ultrasonics’ current technological range, an indication was given that there was the capability to deliver a lasting and efficient solution to this problem.
Ultrasonics was the solution chosen by Coltraco, who are experts in this technology stream, to be a non-invasive, robust, easy to use avoiding the risk of harm to the site engineers. Coltraco’s equipment is designed to improve safety and best practice, ensuring the equipment used by crew/technicians/engineers to conduct such inspections is accurate and calibrated is a necessary one. For this reason, Coltraco calibrated their Intrinsically Safe Platform to application specific purposes. This was set to – 0 = LIQUID 100 + = Air. The Intrinsically Safe Platform was designed to operate in specific environment where the presence of potentially dangerous gases can be experienced.

The solution offered unparalleled accuracy and clarity of indication: the Portalevel Max Industrial. It provides fast operation with 30 second servicing, is accurate up to the true liquid level of 1.5mm and is Zone 1 ATEX Certified and UL Approved.  The unit requires no input from the on-site engineer apart from the simple application of the sensor to the vessel wall. This protects the operator from the health and safety problems that were presented through manual monitoring, as well as increasing efficiency.

The delivery of a solution to the pharmaceutical company allowed the operators of the plant to safely, quickly and accurately monitor the contents within the ammonia vessels. These vessels are integral to the operation of the plant as a whole. This unit is also cost efficient, reducing the amount of partially empty ammonia cylinders returned before emptying, increasing efficiency, and saving the organisation money over time. The Portalevel Intrinsically Safe builds on Coltraco Ultrasonics’ 30 years’ experience in designing, manufacturing and supporting ultrasonic liquid level indicating (ULLI) equipment, operating in 109 Countries and numerous market sectors and environments. The development program was born out of the desire to further improve Coltraco’s existing 9 Portalevel® ULLI designs and taking on board feedback and opinions of their customers.

Protecting your crew and vessel: using ultrasonics to create a Safeship®

The New Zealand Transport Accident Investigation Commission (TAIC) have recently investigated the cause of the 2016 PeeJay V fire and sinking. PeeJay V was a passenger vessel, which at the time of the incident had 53 passengers on board. As a result of the fire and sinking one person suffered smoke inhalation and there was a total loss of the vessel.

The TAIC have concluded that a lack of understanding of the CO2 fixed fire-fighting system contributed to the sinking of the PeeJayV. One of the significant issues was “the CO2 fixed fire-fighting system installed in the engine room could not be fully effective in extinguishing the fire because the space it was protecting could not be fully closed down” and this was partly as a result of the builder and operators of the vessel did not fully appreciate the principles of how the CO2 fixed fire-fighting system operated”.

The TAIC recommended “crew must be fully familiar with and trained in the use of fire-fighting systems on board, otherwise the systems might not be of any use in fighting a fire” which is a key part of the IMO SOLAS Fire Safety Systems (FSS) Ch5. 2.1.1.3: “Means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the container”. The loss of the PeeJayV has exemplified why it is crucial for the compartmentation of the area protected by fixed fire fighting systems and the liquid level of the gaseous extinguishant  to be regularly and easily tested by the crew.

A lack of understanding and servicing of fixed fire fighting installations can endanger the lives of the crew, vessel and cargo in the event of a fire.  One British manufacturer whose mission is to deliver the Safeship® to prevent PeeJay V  type incidents occurring again is Coltraco Ultrasonics. They are committed to improving safety for people, assets and vessels at sea. They focus on benefitting the crew; designing innovative ultrasonic solutions which the crew will be happy to use by being easy to operate, quick, accurate and a better method to traditional techniques. Thus increasing the likelihood of tests being regularly conducted, in line with regulations and even going above and beyond for more frequent testing. By so doing, the crew will be creating a safer ship.

Ultrasonics is proven to be the quickest, easiest and most efficient method to holistically test compartmentation and liquid level inside fixed fire-fighting installations. The Portascanner® 520 is designed to allow the crew to non-destructively conduct regular compartmentation maintenance, with industry leading accuracy. Accompanying this to holistically test the fixed fire-fighting system is the award winning Portalevel® MAX Marine which uses ultrasound to enable identification in under 30 seconds with one person, instead of the traditional 15 minutes, with two people laboriously weighing. Combined with the MAX Marine, The Portasteele® Calculator is an advanced calculator application, that converts the liquid level height of C02, NOVEC™ 1230 and FM-200® liquefied gaseous extinguishant agent readings taken on an ultrasonic non-destructive liquid level indicator device into the agent weight/mass

Fires in wind turbines, nuclear plants, ships… where next?

The risk of fire is prevalent across all safety critical and high value assets. People’s lives are endangered, infrastructure damaged and companies’ reputations decimated if the fire fighting systems do not extinguish the fire. A quick news round up of 3 fire incidences highlights the need for better maintenance, inspection and continuous monitoring of both the fixed fire extinguishing system and the room integrity.

1.Looking back to wind turbine fire in shadow of Saga nuclear plant, Japan

A 60-meter-high wind turbine near a nuclear power plant in northern Kyushu, Japan caught fire on 21st August 2017, posing difficulties for fire-fighting efforts from the danger of falling parts.

A fire department spokesperson said firefighters were unable to shoot water at the flames due to the fear of falling debris.

An official of Tokyo-based JFE Engineering Corp. said the wind turbine is operated by one of its affiliated companies. JFE Engineering said the cause of the fire is under investigation.

The Kushizaki plant in the city’s Chinzeimachikushi district is located about 700 to 800 meters from the Kyushu Electric Power Co.'s Genkai nuclear power plant in Genkai in the same prefecture across the sea.

2.Ineffective Firefighting System and no Room Integrity results in evacuation and total loss of vessel

New Zealand's Transport Accident Investigation Commission has released its report into the tourist vessel PeeJay V which caught fire and sank because the main firefighting system was ineffective and staff did not fully understand how it should work. 

On January 18, 2016, the PeeJay V was on an all-day excursion from Whakatāne out to White Island with 53 passengers and seven crew on board. The PeeJay V was near the end of the journey and approaching the Whakatāne Harbour entrance when fire broke out in the engine room.

The crew released the fixed CO2 fire extinguisher into the engine room, which suppressed the fire for a short time. However, the fire quickly escalated, forcing the skipper to order everyone to abandon the vessel. [sic] The PeeJay V burnt to the waterline and sank. One crew member suffered from smoke inhalation, but otherwise nobody else was seriously injured.[sic]

The Commission also found that the CO2 fire suppression system, which was supposed to work by displacing the air in the engine room with CO2, was not effective in suppressing the fire. This was because air was able to enter the engine room through several openings, including a cable duct that had no means of being closed.[sic]

Three main safety issues identified during the inquiry were:

  • Maritime Rules did not require the PeeJay V to have fire detection or automatic fire alarms installed even though it could carry up to 90 passengers and operate up to 12 nautical miles from the coast.
  • The CO2 fixed fire-fighting system installed in the engine room could not be fully effective in extinguishing the fire because the space it was protecting could not be fully closed down.
  • The builder and operators of the vessel did not fully appreciate the principles of how the CO2 fixed fire-fighting system operated.

Maritime rules did not require the PeeJay V to have fire detection or automatic fire alarms installed even though she could carry up to 90 passengers and operate up to 12 nautical miles from the coast. Maritime New Zealand has agreed to review the maritime rules about fire alarms and remote extinguishers in vessels of this type with enclosed engine spaces. It will also encourage people who design, install and use CO2 fixed fire-fighting systems to fully document and understand how these systems work.
