    Abstract: A motion compensation system is provided for controlling relative movements between a floating vessel and an elongate element, where the elongate element is suspended by the vessel at a first end and extends into a body of water below the floating vessel. An active motion compensator is connected to the elongate element first end via an element arranged in an upper region of an erect support structure and a passive motion compensator is connected to the elongate element first end via the element. The motion compensators are structurally and operationally separate and independent units and are configured for separate and mutually independent operation.

    Abstract: A heave motion compensator (30, 40, 70, 100, 140, 300) for compensating heave motions comprises a cylinder (41) and a piston (44) delimiting a variable volume fluid chamber (49) in said cylinder (41), wherein said piston (44) can oscillate within said cylinder (41), said piston (44) being provided with a seal (48) frictionally engaging said cylinder. The compensator further includes a motor (65) that causes said seal (48) to revolve relative to said cylinder (41) so as to obtain a dynamic friction regime between the seal (48) and the cylinder (41). In a possible embodiment the motor (65) is arranged to rotate said piston (44), and the seal (48) is mounted on said piston (44) so as to rotate along with said piston (44).
