Hatch Cover Maintenance and Operation/Обслуживание и эксплуатация крышки люка

Издание на английском языке
The first edition of this loss-prevention guide, published in 1997, has been widely distributed in the marine industry with the objective of helping to control the substantial level of claims associated with hatch covers. The guide continues to be found useful and so a second edition has been produced. This new edition brings the guide up to date with the addition of some new material; the opportunity has also been taken to revise the presentation.
The objective of the guide remains as before: to provide information in a simple and straightforward way to those onboard ship and those ashore who have an interest in the voyage. The aim is to provide practical guidance to the target audience of ship’s officers, ship operator’s technical staff, surveyors, lawyers and claims handlers.
The guide deals with hatch cover design principles, operation, maintenance and safety.
Appendices are included which provide checklists for routine onboard inspections, notes on recent IACS contributions to hatch cover design and operation, and a glossary of terms.
