3 International Safety Guide for Oil Tankers & Terminals ( ISGOTT ). FOURTH Edition . INTERNATIONAL CHAMBER OF SHIPPING. OIL COMPANIES INTERNATIONAL MARINE FORUM. INTERNATIONAL ASSOCIATION OF PORTS AND HARBORS. The International Chamber of Shipping (ICS) is a voluntary organisation of national shipowners' associations. It was established as long ago as 1921 and represents more than half the world's merchant tonnage. The interests of ICS cover all aspects of maritime affairs, but it is particularly active in the field of marine safety, ship design and construction, pollution prevention and maritime law. ICS has consultative status with several inter-governmental organisations, notably IMO. The Oil Companies International Marine Forum (OCIMF) is a voluntary association of oil companies having an interest in the shipment and terminalling of crude oil and oil products.

4 OCIMF is organised to represent its membership before, and consult with, the International Maritime Organisation (IMO) and other government bodies on matters relating to the shipment and terminalling of crude oil and oil products, including marine pollution and safety. The International Association of Ports and Harbors (IAPH) is a voluntary world-wide association of port authorities, founded in 1955. Current membership includes 230. regular and 154 associate members encompassing 77 countries. IAPH is committed to the exchange and promotion of ideas and technical knowledge on issues of concern to those who work in ports and related industries. Its consultative status with UN and other organisations, including IMO, is a positive benefit in this regard.

7 Printed in England by Witherby & Co. Ltd., 32/36 Aylesbury Street, London, EC1R 0ET. ISGOTT 5. Foreword to Fourth Edition Safety is critical to the well-being and reputation of the tanker industry. The International Safety Guide for Oil Tankers and Terminals, or ISGOTT as it is now widely known, is the standard reference work on the safe operation of oil tankers and the terminals they serve. To remain current, the Guide must keep abreast of changes in vessel design and operating practice and reflect the latest technology. This fourth Edition includes much new guidance on recent developments within the industry. Principal among them is the advent of the double hull tanker as the standard ship. Double hull tankers are not new, but hitherto they have been specialised vessels, generally smaller ships and confined to certain trades.

8 As time passes a growing number of tanker operators will need to familiarise themselves with the special characteristics of double hull vessels. Therefore this new Edition addresses such questions as the possibility of hydrocarbon gas leakage into double hull spaces and the stability of some double hull designs during simultaneous ballast and cargo handling. Account has been taken in this revision of the growing awareness of air pollution and the use of vapour return lines to avoid venting all hydrocarbon vapours to the atmosphere. The potential problems created by over-pressurisation or under-pressurisation of cargo tanks have also been addressed. The opportunity has been taken to improve and update the text in a number of other respects to ensure that ISGOTT continues to provide the best technical guidance on tanker and terminal operations.

9 All operators are urged to ensure that the recommendations in this guide are not only read and fully understood, but also followed. ISGOTT 6. CONTENTS. FOREWORD TO FOURTH Edition 6.
