Year: 2022 Language: English Author: Seamanship International and Witherbys Publishing Format: PDF Edition: 2nd Quality: Scanned pages Number of pages: 346 Description: 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.
