Some customer examples are V Ships, BP Shipping, Wallem Ship Management, P&O and Moller Maersk. Coltraco aim to deliver the Safeship®: to improve safety of crew, cargo and vessels at sea. This is Coltraco’s mission: using the FLEETSAFE® range of innovative, intuitive technology to improve safety. Sinking is the number one cause of loss of ships at sea and fire is the number two. We support you to mitigate these risks through technology: inspecting watertight integrity of the holds, doors and MCTs and inspecting the ships’ fixed fire suppression system.

Saving maritime companies time, risk and money: an accurate, reliable and easy to use package, for any crew members to use. With this package the hatch-covers, doors, MCTs, compartments, pipework, hulls, bulkheads, rotating machinery, pumps, sprinkler systems and gaseous extinguishing installations are protected. The product range is based on integrity, from design, through to life-time support, and is accurate, reliable and easy to use for any crew members. Coltraco Ultrasonics are proud to awards for Safety at Sea and Innovation for the products in the FLEETSAFE® range.


Fires onboard ships are not rare events. In fact, fire remains the 2nd principal reason for loss of ships at sea. When at sea, the crew are required to become fire fighters in a fire event, yet this is not their primary role onboard. Ships tend to use fixed CO2 fire suppression systems because it is effective, and CO2 is a cheap agent. Therefore, often fire safety is treated as a tick-box exercise.

The danger of CO2 loss is highlighted by Carl Stephen Patrick Hunter, CEO of Coltraco Ultrasonics who has 30 years’ experience in the shipping and offshore industry: “We estimate that 20% of ships are sailing with a loss of CO2, due to high pressurisation leakage or accidental discharge. This inevitably means that the design concentration of the CO2 will be insufficient to control fire.”

If the gaseous extinguishing systems are partially empty, due to leakage or discharge, they will not be available in the event of a fire. This a risk that no shipping company can afford, both with the cost of life and cost of vessel loss.

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.

Invest in Safety

Investing in effective, integrated fire protection systems, and in training the crew to inspect these systems is worthwhile:

  • Once CO2 fire suppression systems are installed, it is mandatory to test the systems at least once a year by a certified marine servicing company
    What is less known is that the regulations also demand that the vessels must have “means shall be provided for the crew to safely check the quantity of the fire extinguishing medium in the containers” in between regulatory checks – IMO SOLAS FSS 2.1.1.3.
  • The reason for this is that CO2 is stored under high pressure. This means the agent can leak out the cylinder or accidentally discharge. If it leaks there may be insufficient agent to put out a fire event (scientifically speaking this means “below their design concentration”). So it is important to test the cylinders to ascertain the correct fill of CO2.
  • Traditionally this has been ascertained by manual weighing which requires the system to be switched off, and thus not protecting the ship for the duration of inspection, then each cylinder has to be dismantled from the manifold, requiring two people to carry the cylinder (45KG CO2 fill usually) onto a weigh scale then returned and recoupled etc which can 15 minutes.
  • Considering the average ship may have 600 cylinders, and a ship may only be in port for 4 hours, the need for speed is paramount to conduct rigorous inspection of each cylinder.
  • Today you can use portable ultrasonic liquid level indicators, the Portalevel® MAX Marine to check the fill level of agent takes one person and just 30 second*. If weight is still the preferred result, a calculator can convert the level to weight in 30 seconds by an intuitive tablet app the Portasteele® CALCULATOR.

To ensure the CO2 system contains the correct amount of CO2 to deliver the design concentration that will be needed to extinguish the fire event if it occurs, ships need to test their CO2 systems for contents in-between the annual certification checks by marine servicing companies.

Why Choose the Portalevel® MAX MARINE?

Due to the quicker and easier method of servicing a cylinder with this device, and results which can be easily repeated for reliability and accuracy, Portalevel® MAX Marine allows vessels to be in full compliance with the FSS code in-between the annual certification intervals because the crew will be happy to conduct contents checking themselves at sea.

Portalevel® MAX Marine ensures inadequately filled cylinders can be easily and safely detected, minimising risk to the crew, asset and vessel in the event of a fire, by ensuring the integrity of the fire suppression system

Decreasing the time to regularly and effectively test cylinder agent weights, will reduce the inconvenience and costly man hours required for testing. The reduction of man hours reduces the cost in the long term to a vessel operation, even compared to a low rate marine servicing company. As such, there is more time to perform more frequent checks without the dangers of physically weighing cylinders, such as accidental explosive discharge, strain related injuries to crew and the fire danger to a vessel during testing because the system is disarmed.

Safer, Faster and Cheaper

With the Portalevel® MAX MARINE, ultrasonic liquid level indicator, engineers can check the contents of CO2 safer, faster and cheaper. With the ability to test cylinders in situ and in just 30 seconds, the Portalevel® MAX saves time so more inspections can be carried out. Using the Portalevel® MAX MARINE saves labour costs and removes the risk of injuries, ensuring vessel safety in an affordable manner.

The Portalevel® MAX MARINE allows the crew to be in charge of checking the CO2 systems, as many times as needed: ensuring that the systems will be working when they are needed.

  • ABS Type Approved Portalevel® MAX MARINE is designed primarily for the vessels’ crew to inspect large fire suppression systems of up to 600 cylinders.
  • Coltraco’s innovative method 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 laboriously weighing.

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. Shipping must continue in its mission to improve safety of life at sea, for the crew’s protection. It’s time to conduct your risk assessment and start maintaining your gaseous extinguishing systems. Choose the quickest, easiest and effective way to maintain your fire systems: The Portalevel® MAX Marine.
