摘要： A heave compensation and riser tensioning system and method for an offshore drilling or production operation. The system includes at least one motor assembly, wherein the motor assembly further includes at least one motor; a drum assembly bracket; at least one wire drum; and at least one wire rope. The at least one wire rope has a first end fixedly attached to the wire drum, and a second end fixedly attached to a riser tension ring. The at least one motor is coupled to the at least one wire drum via a gear assembly.

摘要： A device for connecting and disconnecting an active compensator actuator or additional passive compensator actuators from a passive compensated load bearing unit during operation and at static suspended condition. The device comprises a connection arrangement (7), which is operatively connected to a crown block. The connection device (7) is adapted to selectively grip a second end (18) of the heave compensator actuator (1). The device comprises further a safety arrangement (6) which are adapted to selectively grip the second end (18) of the heave compensator actuator (1) when it is not in engagement with the connection arrangement (7), the device comprises also a support arrangement (2), which is adapted to support the heave compensator actuator when it is not connected to the crown block (8).
