Overview
This book provides guidance on safe operation of anchor handling tug supply vessels. It discusses the theory and techniques used in anchor handling and towing operations, AHTS vessel capability, roles of onboard personnel and potential dangers.
This book sets out in practical and simple terms the theoretical knowledge, methods and techniques that should be used to avoid placing AHTS vessels at unnecessary risk during routine operations. It outlines the forces acting on the vessel and discusses vessel capabilities and equipment. Case studies of the Stevns Power and Bourbon Dolphin are used to illustrate the potential dangers in AHTS operations.
This book will benefit Masters and crew on AHTS vessels, as well as towmasters, rig movers, barge masters, tower foremen and shore-based personnel who utilise these vessels in anchor handling and towing duties.
