This publication provides ships’ officers, tanker terminal personnel and selected management staff ashore an understanding of the principles involved in the safe loading, transportation and discharging of liquefied gases. The revised edition includes both theoretical and practical aspects of ship operations, with the objectives of ensuring efficient tanker operations and the safety and health of personnel throughout all stages of the voyage and while alongside in the terminal.

This title offers comprehensive detail on the bulk transport at sea of liquefied petroleum gas (LPG), liquefied natural gas (LNG) and chemical gases, as well as aspects of various cargo handling systems. It includes a chapter on cargo calculations, ensuring ships’ crew are aware of correct loading quantities prior to cargo operations.

This book provides an assessment of gases, including their hazards and properties, before considering all stages of LPG and LNG operations. A detailed overview of STS operations is also included.

Processes such as reliquefaction and gassing-up are illustrated by 3D models, a beneficial visual aid to those in preparation and operation of modern gas carrying ships, or in operation of a related shore facility. The guidance concludes with a consideration of general emergency procedures, including the principal hazards on gas carriers.

These training notes are designed to give ships’ officers, tanker terminal personnel and selected management staff ashore an understanding of the principles involved in the safe loading, transportation and discharging of liquefied gases.


Guidance and best practice on the bulk transport at sea of liquefied petroleum gases (LPGs), liquefied natural gas (LNG) and chemical gases are considered in detail.


The notes begin with an assessment of gases, including their hazards and properties. Gas carrier characteristics and design are then discussed, with reference to the relevant Conventions, Codes, and regulations, including the International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code). The notes then describe the purpose and general operation of the various cargo handling systems found on gas carriers (including pipes, valves, cargo pumps, reliquefaction plants, compressors, inert gas plants and other auxiliary systems).


All stages of LPG and LNG operations are explored in great detail, with a focus on important safety topics, as well as a walk through different cargo stages during a tanker voyage (drying, inerting, gassing-up, cooldown, loading and discharge). These notes also provide an overview of STS operations for gas carriers, the basics of liquefied gas cargo calculations, terminal operations, and the use of equipment for tank atmosphere evaluation and safe entry into enclosed spaces. The guidance concludes with consideration of general emergency procedures, including the principal hazards on gas carriers.


Gas carriers are one of the safest ship types in the maritime community and this enviable record is made possible by continued familiarity with best practice and procedure by all involved. The notes include both theoretical and practical aspects of ship operations, with the objectives of ensuring efficient tanker operations and the safety and health of personnel throughout all stages of the voyage and while alongside in the terminal.
