Double Hull Oil Tankers. Guidelines for Surveys, Assessment and Repair of Hull Structures IACS № 96 / Двухкорпусные нефтяные танкеры. Руководство по обследованию, оценке и ремонту корпусных конструкций

Книга на английском языке
The International Association of Classification Societies (IACS) is introducing a series of manuals with the intention of giving guidelines to assist the Surveyors of IACS Member Societies, and other interested parties involved in the survey, assessment and repair of hull structures for certain ship types.
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. Figures 1 & 2 show the general views of typical double hull oil tankers with two longitudinal bulkheads or one centreline longitudinal bulkhead respectively.
