This publication explains different permutations of hatch cover type, securing devices and methods for opening and closing, as well as the various defects that may be encountered. It will benefit all those associated with the care, maintenance, operation and inspection of hatch covers (eg deck officers, deck ratings, superintendents and surveyors).
The correct operation, care and maintenance of hatch covers are critical to a ship’s safety and its ability to carry cargo without damage. This publication explains the complexities of the structure and the machinery, repairs and surveys required to ensure ongoing safety and efficiency.
