Marine technology is experiencing rapid change, particularly in the areas of ship design, building and operation. New technologies not only have to be developed but also quickly incorporated and put into use in order for the various organizations involved to remain competitive. Containing papers presented at the Fourth International Conference on Marine Technology, this volume reviews both traditional and improved techniques in the design, building and operation of ships, and also describes research and development taking place in such areas as new and lighter materials, robotics, ergonomics, and environmental concerns. The papers included are divided under the following headings: shipbuilding and design; design philosophy; hydrodynamics; materials and fabrication in shipbuilding; ship propulsion, equipment and automation; navigation and ship operation; fast marine craft; reliability and safety in marine Technology; quality assurance in ship technology; environmental issues; deep sea systems and vehicles; management aspects; and condition monitoring and fault diagnosis.
