This publication establishes the recommended minimum requirements that will help ship and terminal designers, ship operators and mooring line manufacturers on safe mooring system design, with an emphasis on the safety of ship and terminal personnel.

This fourth edition has been extensively updated and addresses lessons learned from incidents such as failures of HMSF mooring lines. It also reflects industry developments – the move towards human-centred design principles and human factors in mooring operations are explored in depth. New regulations from the IMO on the safety of mooring and options of alternative mooring technologies are also outlined.

Effective management of health, safety and environmental protection is critical to the tanker industry. This sixth edition of ISGOTT has been revised and updated by industry experts to provide essential guidance on current technology, best practice and legislation. It remains the definitive reference document for the safe operation of oil tankers and the marine terminals they visit.

This sixth edition has been updated by OCIMF and ICS together with the International Association of Ports and Harbors (IAPH). Support has also been provided by other industry associations including INTERTANKO, the Society of International Gas Tanker and Terminal Operators (SIGTTO) and the Society for Gas as a Marine Fuel (SGMF).

The book covers a range of topical issues including gas detection, the toxicity and toxic effects of petroleum products (including benzene and hydrogen sulphide), the generation of static electricity and stray currents, fire protection and the growing use of mobile electronic technology. Many areas of the book have been reappraised and new topics, such as cyber security, have been added.

The Ship/Shore Safety and Bunkering Operations Checklists have also been revised to reflect changes in the understanding of the impact of human factors on their effective use. The layout of the book has been significantly improved to make it easier to navigate, with the addition of coloured sections and tabs. The text is supported throughout with new and updated illustrations.

The MTMSA process offers a standard framework for terminal operators to assess and improve their management systems. Self assessment can be used by terminal operators to verify that their management systems are comprehensive and promote safety and environmental excellence, and to ensure that any risks have been identified, analysed and reduced to a level that is as low as reasonably practicable.

Terminal operators can use their assessment results to develop a plan to continuously improve safety and environmental performance and transfer best practice across their operations through the consistent application of enhanced processes and procedures.

This document includes best practice guidance based on current international legislation and recognised industry guidelines and codes of practice. In addition, in the online version, supplementary information will be available via a ‘Help’ facility to assist users when completing the assessment.
