Abstract
In the offshore and dredging industries activities are carried out during which machinery that is put overboard comes into contact with the seabed whilst the ships or platforms are moving. For dredgers this could be the suction pipe of a hopper dredger. For offshore installations the examples would include the drilling of a well, installing heavy objects on the seabed, or the laying of pipes with roll and pitch compensated j-lay towers. The movements of the ship resulting from the sea swell and wind waves mean that large variations occur in the forces that are exerted on the suction pipe, the drill pipe, the lifting cable or in the pipelines that are being installed on the seabed. Heave compensation systems are used to compensate, as much as possible, for these movements. A distinction is made between linear and rotating compensation systems. In this chapter we will discuss linear compensation systems.
