The extreme weather and sea conditions of the Northern North Sea and the consequential generally low performance rate of crane ships and barges in general, particularly during the winter months, has led to the concept design and construction of the very large semi-submersible crane vessels which are now being brought into service. This paper describes the important features of the S.S.C.V. 'Balder' with emphasis placed on its functions as a floating foundation of heavy lift cranes. Some details of an analysis of the workability rate of the Balder is given. A comparison of this rate with that of a conventional crane ship clearly indicates the operational advantages of the vessel. (Se)
