DNV DNV GUIDELINES 22 PDF

Introduction

This Guideline is based on DNV’s observations and accumulated experience in advising ship owners on laying-up vessels and represents a full revision of our recommended practices from the major lay-ups in the shipping industry during the 1970s and 1980s.

The Guideline provides a systematic and cost effective approach for preparing the vessel for lay-up and maintaining it in a safe and cost effective condition during lay-up.

An overview of the various parties’ involvement in laying-up of vessels is given in the start of the document in order to assist ship owners in evaluating the different scenarios of lay-ups.

If the vessel is laid-up in compliance with the recommendations given in sections 9 and 10, Det Norske Veritas AS may upon a successful verification, issue a Lay-up Declaration and Lay-up Preservation Declaration respectively stating compliance with said requirements.

Finally, some practical procedures for re-commissioning the vessel are given in section 11.

It should be noted that the guidance herein are not classification requirements. The recommendations given are of a general character. Maritime, national or local authorities and insurance companies may have individual requirements not covered by this document.

Furthermore, the specific requirements of equipment manufacturers may take precedence over the guidance presented.
