Hatch Cover Tightness Testing Device HATCHTITE™ is a robust and versatile instrument for the reliable testing of water tightness of cargo hatch covers to prevent cargo damage. Unlike hose and chalk tests, which only demonstrate whether or not there is contact between the rubber packing and compression bar, HATCHTITE™ indicates when you actually have the required compression to prevent water getting into the hold space. HATCHTITE™ uses a transmitter placed inside the cargo hold (empty or with cargo) emitting ultrasound waves. With the hatch covers closed, a hand held telescopic microphone is used at the hatch cover interfaces. The system is fully compliant with IACS Unified Requirement U.R.Z17 and • Pin-points small leaks and areas that lack compression • Simple to use, accurate and reliable • Can be carried without interfering with ship operations • No need for water to determine leaks • Full ABS Type approval

The principal of operation for ultrasonic cargo hatch tightness testing is remarkably simple. An ultrasonic transmitter is placed in the hold (empty or with cargo) and emits ultrasonic waves. The hatch cover is then closed, fully cleated and battened. The surveyor or operator then uses the HATCHTITE™ ultrasonic detector to 'listen' from the outside and pick up all 'leaking' ultrasonic sounds that pass through the sealing arrangements, vents and/or cracks. The effectiveness of a hatch cover tester is determined by the amount of sound energy that reaches the hatch cover, which is in turn...
