Guidance Manual for Maintenance of Tanker Structures
9 January 2008
This publication covers the process of planning, inspecting and repairing the steel structure and any protective coatings or protection systems. Reference is made to the requirements of the ISM Code. The practices and procedures described can be applied to both single- and double-hulled tankers. The recommendations apply to oil tankers of any size and configuration.
Overview
Many regulations and publications on the survey and operation of tankers require that the Owner, or his manager, applies "effective maintenance" or "normal Maintenance" to the ship's structure. The documentation required for planning class renewal surveys includes records of Owner's inspections, which are to form part of the survey report file on board. The certificates issued by some classification societies state that the ship is classed "subject to normal maintenance". However, when asking different tanker Owners what they understood by "normal maintenance", all had their own ideas and it was apparent that there is no internationally accepted concept of "normal circumstances", even allowing for the fact that tankers of different ages and designs will require different approaches to maintenance.
The Tanker Structure Co-operative Forum (TSCF) has published several Manuals on the Maintenance and Repair of Structures, but these have never been assembled in a format that provides an answer to the question "what is meant by effective maintenance?" The purpose of this manual, therefore, is to draw on previously published guidance, combined with the latest experience of the TSCF's and INTERTANKO's membership to produce a book that can be used by any Owner or manager of any tanker afloat as a guide to effective maintenance of the structure. Advice on how inspection and maintenance can be facilitated by improved design is included in Appendix 3.
Furthermore, the Guide suggests practices for the various elements of maintenance, such as paint condition, steel thickness and handling of fractures.
If an Owner adopts the practices set down in this manual, he should be confident that he will meet the ISM requirement to establish procedures to ensure that the ship's structure is maintained in conformity with the provisions of relevant rules and regulations.
