Floating Structures and Offshore Operations

These proceedings deal with floating structures and offshore operations in relation to the exploration, exploitation and transportation of offshore oil and gas resources and all associated construction and installation activities. The papers provide an up-to-date review of current developments in the field of floating production systems, and present the state-of-the-art of design methods for floating systems, mooring and positioning. The book achieves a good balance between the viewpoints of industry and research/academia, and will thus interest various groups of readers: technical managers of oil companies and offshore contractors, design firms and consultants in the offshore industry, constructors of offshore structures, research institutes, and technical universities
