This volume covers the use of spread mooring systems in the context of barges. It deals with both static (drilling unit/support ship) and mobile (pipelaying/trenching) mooring spreads. The book will assist barge Masters, barge movers, tower foremen, barge engineers, marine advisors, warranty surveyors and others to use ‘in the field’ to assist them in their work. Previously published by Clarkson Research Services Ltd.
This book concentrates on the mooring systems of semi-submersibles, but the procedures and equipment used can apply to other types of specialist vessels. It includes practical guidance on topics such as anchor types. The text is supported by detailed diagrams of concepts such as deployment theory, as well as graphical presentation of anchor holding capacity. Other topics detailed include mooring equipment, the problems associated with anchoring equipment and advice on operational safety.
