The information in this book is provided primarily for organisations involved in the transportation of liquefied gas cargoes, including support craft, facilities and ships. It may also be of assistance to regulators and government agencies.
The book demonstrates how risk assessment may be used to develop response and protection strategies for support craft. It considers the ‘top events’ that will typically concern operators of support craft (i.e. loss of containment, collision/grounding, loss of position, and evacuation, rescue and pollution prevention). It discusses the threats, barriers and consequences of each event and highlights the part that support craft can play in mitigating risk through planning and operational readiness. The text is supported with colour illustrations and photographs, as well as diagrams showing the ‘bowtie’ method of risk assessment and management.
The Annexes provide useful information on:
• Response considerations and planning
• Equipment and capabilities of support craft
• Water-spray systems
• Support craft emergency response competencies
• Fire and gas dispersion modelling.
