Watertight Integrity Monitoring
We have developed the Portascanner® WATERTIGHT PRO. The Portascanner® WATERTIGHT PRO is an ultrasonic instrument used for the location and quantification of leak-sites in watertight compartment Multiple Cable Transit Areas and Watertight Compartment Doors at sea, but more importantly and uniquely, we have designed the instrument with the capability to calculate the water flow rate through them in the event of compartment flooding, to enhance and advance Damage Control and Safety & Survivability in warships and submarines. We developed this with the purpose of contributing to the internal “damage control battle” of Naval warships to save the ship at the damage moment.
The key advantages of the Portascanner® Watertight PRO are:
It is designed to be used to identify, measure, and remedy potential leak-sites in and around the personnel-carrying vehicle compartment, crew compartments, and the engine compartment. This platform can measure the leak area during inspection and calculate the total flow rates of water which would ingress under different water pressures and sea states. This allows a unique ability to quantify the risk to specific areas in a structure.
These are liable to slow seepage or accidental discharge; if the contents do not exist, the design concentration cannot be developed to extinguish a ship or submarine fire and challenging to test at sea where they are most-necessary. Liquified Fixed Gaseous Extinguishing Systems, such as Halon, CO2, FM-200™ & NOVEC™ 1230, are gases stored at very high pressures, making them liable to slow seepage and accidental discharge; if the contents fall below their ability to deliver the design concentration required, the remaining extinguishing gas will not extinguish the fire event. IMO SOLAS II/21.3 state that the crew must have the means to, “periodically test the watertight doors and all mechanisms at least once a week”. IMO SOLAS Fire Suppressions Safety Code state that the “crew must have the means to test the contents” its fixed extinguishing systems at sea, for this. This is the reason why we designed the Portalevel® MAX MARINE PLUS hand-held instrument, enabling the crew to test for the contents of liquefied CO2, FM-200™ and NOVEC™ 1230 Clean Agent extinguishing systems to an accuracy of +/-1.5mm, contained within the highly pressurised gases contained within their large cylinders.
The key advantages of Portalevel® MAX PLUS include:
For 4 years we have been designing the means for a Naval Crew to monitor the contents of their Non-liquefied fixed fire Gaseous Extinguishing Systems containing the non-liquefied gas, Inergen™ and which sometimes replaces the liquefied gaseous extinguishants such as Halon or NOVEC™ 1230. Inergen™ is typically stored in 45KG/100lb cylinders at pressures between of up to 300 Bar. At such pressures they are also subject to slow seepage of contents or occasionally accidental discharge. If the gas is insufficient at sea to develop the design concentration required, the fire event will not be extinguished. The land-based fire industry who install the systems leave the maritime user dependent on the dockside maintenance and pressure gauges to monitor pressure, but this does not enable the warship or submarine to monitor the contents at sea. Our instrument allows Navies to monitor both at sea, so that the integrity of the Inergen™ system can be maintained by the crew who depend on it.

As one of the world’s first innovative portable ultrasonic liquid level indicator with a brand new dual certification, Coltraco Ultrasonic’s Portalevel® INTRINSICALLY SAFE (Portalevel® IS) meets stringent safety standards for explosive atmospheres, making it suitable for use globally in both Zone 1 and Zone 2 hazardous areas. The device measures liquid levels contained in fire suppression cylinders and other types of tanks stored in hazardous zone environments.
In the maritime industry, ensuring safety isn’t just a best practice—it’s a necessity. According to Lloyd’s List, almost 10% of all total losses at sea in the last decade were caused by fires onboard. As NTSB Chairman Robert Sumwalt rightly said, “Safety isn’t something you have, it’s something you do.” When lives are at stake, neglecting fire systems and their maintenance is simply unacceptable.
