Hatch Cover Supplement This supplement was made available to North of England P&I Members in the 58th Edition of their Newsletter Signals.  It offers insight into surveying hatch covers and the top ten hatch defects.

“The Association may periodically require a ship’s hatch covers to be tested for weathertightness.  Similar surveys are also often required by classification societies, and representatives of cargo shippers, particularly where the cargo is sensitive to water damage. These surveys may be done by the traditional hose test or using the more modern method of ultrasonic leak detection.”
