SKU: 0024.WS1742K

This manual gives guidelines for a double hull oil tanker which is constructed primarily for the carriage of oil in bulk and which has the cargo tanks protected by a double hull which extends for the entire length of the cargo area, consisting of double sides and double bottom spaces for the carriage of water ballast or void spaces.

The guidelines focus on the IACS Member Societies’ survey procedures but may also be useful in connection with survey/examination schemes of other regulatory bodies, owners and operators.

This manual has been developed using the best information currently available. It is intended only as guidance in support of the sound judgement of Surveyors, and is to be used at the Surveyors' discretion.
This book includes a review of survey preparation guidelines, which cover the safety aspects related to the performance of the survey, the necessary access facilities, and the preparation necessary before the surveys can be carried out.

The survey guidelines encompass the different main structural areas of the hull where damages have been recorded, focusing on the main features of the structural items of each area.

An important feature of the manual is the inclusion of the section which illustrates examples of structural deterioration and damages related to each structural area and gives what to look for, possible cause, and recommended repair methods, when considered appropriate.
