System for transporting an offshore structure, the system comprising: a transport apparatus, in particular a vessel or a vehicle, which is configured to receive an offshore structure and to form a slip joint with a slip joint section of a received offshore structure, wherein the system is configured to enter a releasable state, from a fixing state, wherein, in the releasable state, the slip joint formed by the transport apparatus and the offshore structure is smaller than that force in the fixing state.

System for transporting an offshore structure

A turbine, wherein a propeller is mounted to said turbine, rotatable around a propeller axis, wherein a multi piston pump is provided, said multi piston pump being drivable by said propeller for pressurizing a pumping fluid, wherein the multi piston pump comprises a central part and a drive ring extending around the central part, wherein the central part comprises a series of piston-cylinder assemblies which are each compressible and extendible in a respective radial direction with respect to a common central axis, wherein each of the piston-cylinder assemblies is directly or indirectly engageable by the drive ring for radial compression thereof, in particular for pressurizing said pumping fluid, wherein at least one of the piston-cylinder assemblies is provided with a hydraulic and/or pneumatic biasing means for biasing, at least selectively biasing, at least part of that piston-cylinder assembly towards engagement with the drive ring, in particular substantially independent of and/or complementary to a biasing by a pressure of pumping fluid at that piston-cylinder assembly.

A vessel including a motion compensation platform are disclosed. The platform comprises at least one carrier for bearing, moving and/or transferring a load, and a gangway provided with a first end pivotably connected to the carrier and a second end for contacting a target area. Further, the platform comprises a multiple number of first actuators for moving the carrier relative to the vessel, and at least a second actuator for moving the gangway relative to the carrier. The platform also comprises a control system arranged for driving the multiple number of first actuators, and motion sensors for measuring motions relative to at least one element in a target area, which measurements are used as input for the control system. The control system is also arranged for driving the at least one second actuator.
