Monitor your hatch covers

Permascanner® Dynamic is our semi-fixed ultrasonic watertight integrity test indicating system for the dynamic testing of hatch covers, holds, bulkheads, cable transits and watertight doors and compartments at sea. Derived from its sister product the Portascanner®, Permascanner™ Dynamic is designed to quickly identify leak sites in their extent and precise location, whilst at sea. 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.

Using a portable ultrasonic watertight integrity tester, Coltraco Ultrasonics’ Portascanner® functions on similar principles, detecting the smallest leak size 0.06 mm in diameter which is the most mathematically accurate in the world +/-0.02mm. As an example of how a leak will compromise the stability of a vessel, a leak diameter of one mm under just one metres depth of water below sea level will correspond to a leak of 12,500 millilitres per hour. This means up to 911 cans of soft drinks worth of water in a day. This highlights the importance of watertight integrity.

Portascanner® Watertight is ideal for cable transit areas watertight testing whereas considered appropriate for scuttles, shell doors, hatch – covers, doors, flanges and steering gear hatches are the few others. Manufactured within modern terms, it qualifies to cope up with inspection of leak sites of critical sealing.
