This illustrated guide explains the fundamental importance of weathertight hatch covers to the safe and profitable operation of cargo ships. Poorly maintained or secured hatch covers can result in total losses in heavy seas and are one of the principal sources of cargo damage claims.

The guide describes the various types of hatch cover in use today and explains how they should be inspected, maintained and operated to ensure maximum effectiveness and safety. The second edition has been extensively revised and updated and includes information on hatch cover testing, recent IACS contributions to hatch cover design and operation, plus a glossary of terms. The guide is intended for ships’ officers, ship operators, technical staff, surveyors, lawyers and claims handlers.

The objective of this guide remains as before: to provide information in straightforward way to those on board ship and those ashore who have an interest in the voyage. The aim is to provide practical guidance to the target audience of ships’ officers, ship operators, 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.
