Three Classification Societies formally agreed in early 2002 to commence a major project to jointly develop a single set of Classification Rules and Procedures for the hull structure of oil tankers. One of the principle objectives in achieving the overall goal was to develop a set of common Rules that would avoid the possible competition between Classification Societies on the minimum safety standards. Since that decision, the three Classification Societies have combined their unique experience and expertise to produce a set of Common Structural Rules for Double Hull Oil Tankers of length equal to or greater than 150 metres and such Rules are presented in this document. It is to be particularly noted that in developing these Rules due cognizance has been taken of ensuring that the overall safety of the hull structure is equivalent or better than existing design criteria, has sufficient durability in terms of corrosion margin and fatigue strength, and the need to transparently define the relationship between required scantlings for design and those for renewal.
