A Rigid-Flexible Hybrid Wave Motion Compensation Device for Offshore Floating Lifting Platform

Abstract

The invention relates to the field of marine machinery and equipment, and its purpose is to provide a rigid-flexible hybrid wave motion compensation device for an offshore floating hoisting platform, which is used for wave compensation in the process of replenishing cargo. The compensation device includes a hoisting mechanism arranged on a replenishment ship And the rigid-flexible hybrid compensating mechanism connected with the lifting mechanism at the upper part. The compensation device of the present invention has excellent anti-interference performance, can make the cargo land on the ship 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 more flexibility. Strong, 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 hybrid wave motion compensation device for an offshore floating hoisting platform. 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 the four degrees of freedom of heave, roll, pitch and yaw will be mainly caused by the action of waves, and this relative movement will intensify with the escalation of sea conditions, which will easily cause the cargo hoisted by the hoist to deviate from the normal position. In severe cases, it may even collide with the superstructure or the hull of the deck, causing unnec...
