As the offshore industry moves steadily into deeper water, and the use of man and manned vehicles becomes increasingly dangerous, expensive and impracticable, so the tools of remote intervention have to be developed and exploited. These proceedings promote these technologies, and are applicable to a variety of industries, including hydrocarbon exploration companies, defence industries, deep ocean mineral exploitation, and salvage operations.

The volume contains papers, presented at an SUT international conference on 10-12 April 1997, by specialists in remote intervention and robotic technology, analysing state-of the-art systems. The authors look ahead at other technologies that can be utilised, emphasising industry’s requirements for the next millennium under the sea.
