Over 40% of all P&I claims are due to damaged cargo caused by water ingress via the hatch covers. This represents $46.9m of damaged cargo every year. As a result, reports of leaking hatch covers are the most frequent cause for selecting a vessel for an unscheduled condition survey.

Hatch covers on bulk carriers are subject to an annual inspection by the Classification Societies surveyors. The inspection covers the structural parts of the coamings and hatch covers as well as examining the closing, sealing and securing devices.

Ultrasonic testing is very simple in its operation and is the most accurate way to ensure your hatches
are functioning correctly. Using just a transmitter and a detector the transmitter emits ultrasonic
waves and is placed in the cargo hold. The hatch cover is closed, fully cleated and battened. The
operator then uses the hand-held detector to listen for the ultrasonic waves from the outside, picking up all sounds that pass through the sealing arrangements, vents or cracks.
