This book provides guidance for shipowners and operators who are new to LNG ship operation. It highlights the relevant statutory requirements for training LNG tanker crews, the STCW that are applicable to gas tankers, and the application of the ISM Code (for training and management of tanker crews). This book draws on the experience of SIGTTO member companies who have extensive operating expertise in this area.

The book outlines current practice in LNG ship management companies, particularly in relation to training and experience, and looks at the operational risks involved in gas tanker and terminal operations that arise from transport, storage and transfer of liquefied natural gas and petroleum gas. The risks involved are unique to this industry and as a result require specific measures to manage them within tolerable limits. Gas terminals are often sited within established ports, meaning that the operations of the port and gas terminals serving them have a common operational environment. This means that the industry members have gained invaluable experience in carrying out gas operations in a port environment.

This book highlights the risks involved when managing gas shipping operations, which is useful information for those administering ports and providing essential services within port areas.

Operators require both a systematic assessment of operating risk and a range of risk reduction measures that can be tailored to specific situations. The guidance and information provided in this book aims to satisfy these needs.
