Hatch cover tightness: a major concern for the maritime industry!

Although it is a well-known fact that deficient hatch covers are a vehicle for commercial disasters, it’s often overlooked that leaky hatch covers may also adversely affect the Classification-and Statutory status of the ship (Class rules, Loadline, Fire Safety, ISM, ...).

The demand in ultrasonic hatch cover testing is increasing, mainly within the scope of cargo loss prevention initiatives or cargo claim investigations. However, and with the use of Class Type Approved ultrasonic equipment, several IACS members and P&I Clubs are now accepting and supporting ultrasonic tightness testing of hatch covers in lieu of hose testing. Also lot of shipyards and ship-owners are now convinced about the effectiveness and advantages of using ultrasonic testing as a preventive method.

Don't miss the opportunity to learn more about hatch cover inspections, ultrasonic tightness testing and to obtain your Certificate of Qualification for the Sherlog Class Type Approved Ultrasonic Hatch Cover Tightness Testing Equipment by attending one of the future training courses.
