SHIP MOTION-COMPENSATION SYSTEMS

Drilling from a structure subject to wave motion raises problems of motion compensation. In recent years these have become more acute as the offshore petroleum industry exploits the hydrocarbon resources located in more difficult areas. Of the many problems introduced by movement of the platform, two are discussed here: the isolation of the drill-string from the heave motion of the platform and the tensioning of the marine riser. Principles of operation and constructional aspects of compensation systems are discussed.
