This publication on the alleviation of excessive surge pressure provides practical advice on surge hazards & risk management. It also outlines the principal design & operational recommendations for cargo transfer systems. It will benefit managers, designers, engineers & operators of liquefied gas carriers & terminal loading & unloading systems. These guidelines will assist the operating management of terminals & liquefied gas carriers in reviewing the design, engineering & operating procedures of cargo transfer systems. The information provided will enable users to: • Recognise the potential hazards of surge pressure• Understand the factors that affect or create surge pressures• Avoid the generation of excessive surge pressures & momentum change• Review the engineering & operating procedures of the cargo transfer system• Understand aspects of surge pressure control on the other side of the ship/shore interface to enable mutual understanding of safe transfer procedures• Understand the potential benefits of a linked ship/shore ESD system in mitigating surge pressures.
