VESSEL, A MOTION PLATFORM, A CONTROL SYSTEM, A METHOD FOR COMPENSATING MOTIONS OF A VESSEL AND A COMPUTER PROGRAM PRODUCT

摘要

The invention relates to a vessel including a motion compensation platform. 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.

1. A method for controlling a motion compensation platform of a vessel, the motion compensation platform comprising a carrier and a gangway having a proximal first end and a distal second end for approaching a target area, the method comprising:
(a) measuring motion relative to an element in the target area; (b) moving the carrier relative to the vessel to partly compensate for the relative motion measured in step (a); and (c) moving the gangway relative to the carrier to partly compensate for the relative motion measured in step (a), wherein steps (b) and (c), in combination, reduce actual motion between the second end of the gangway and the target area.
