The present invention relates to the field of marine machinery and equipment, and its purpose is to provide a rigid-flexible multi-dimensional wave motion compensation device for offshore floating platforms, which is used for wave compensation in the process of replenishing cargo. mechanism and the rigid-flexible hybrid compensating mechanism connected with the lifting mechanism at the upper part. The compensation device of the present invention has quite excellent anti-interference performance, can make the cargo land more stably and accurately, and effectively protect the safety of the cargo, hull and staff, and the rigid-flexible compensation control has a large working space and flexibility Stronger, able to respond to changes in a timely manner, and the dynamic control effect is good. The compensation device provided by the invention solves the problems that the existing active heave compensation device cannot meet the actual application requirements and has poor compensation effect.
Description
technical field [0001] The invention relates to the technical field of marine machinery and equipment, in particular to a rigid-flexible multi-dimensional wave motion compensation device for offshore floating platforms. Background technique [0002] The marine environment is complex and changeable. When ships and other offshore floating working platforms are in parallel for replenishment, due to factors such as the tonnage, scale, and line shape of the supply ship and the receiving ship, and the relative positions of the two ships on the waves, the two ships will be tied together. The relative movement of six degrees of freedom of sway, surge, heave, roll, pitch and yaw will be caused by the action of waves, and this relative movement will intensify with the escalation of sea conditions, which will easily cause the hoisting machine to hang The cargo slips and deviates from the normal landing point, and even collides with the superstructure or the hull of the deck in serious ...
