IACS classification society ClassNK released their latest updated version of Good Maintenance Onboard Ships October 2017.  First published in 1994, this latest version of the booklet has been expanded to incorporate ideas and comments from port state control authorities, shipowners, and mariners, as well as extensive data compiled by the Society itself.

This publication provides a comprehensive set of four checklists for shipmasters, crew, shipowners, and other key personnel that covers every aspect of statutory requirements with clear references to the relevant regulations.  These four checklists cover items essential to routine maintenance, PSC inspections, Safety Management Systems, and International Ship and Port Facility Security.  An Appendix has been newly added which includes photos of the most common deficiencies found onboard ship.  Advice is also provided on how to address key maintenance issues, including how to check many specific items and the action to be taken when problems are found.
