An electric wave active compensation boarding system and its control method

Abstract

The invention relates to an electric ocean wave active compensation embarkation system and a control method thereof, and relates to the technical field of marine engineering. The system comprises a rolling compensation mechanism, a pitching compensation mechanism, a stretching and retracting compensation mechanism, a pose detecting system, a movement control system and an electrical system. The method comprises the following steps: connecting a base with a deck of a ship; placing the tail end of the system on a marine fan platform, wherein the pose and position of the ship can be changed due to the fact that the ship is affected by ocean waves; detecting the ship change position and a posture change parameter by using the pose detecting system; providing control information feedback to the movement control system; and controlling the rolling compensation mechanism, the pitching compensation mechanism and the stretching and retracting compensation mechanism to actively compensate the ocean waves in real time by using the movement control system according to parameters of the pose detecting system through model resolving and motion control calculation. The ocean waves are actively compensated, and therefore, maintenance staffs can safely and reliably walk on the marine fan platform.

Description

technical field [0001] The invention relates to an electric sea wave active compensation boarding system and a control method thereof, which relate to the technical field of marine engineering. Background technique [0002] Wind power generation is one of the power generation methods with the most mature technology, the most developmental conditions and the most promising development prospects in the field of new energy. All countries regard it as the most important part of the new energy strategy. my country is rich in offshore wind energy resources, with an installed capacity of about 200 million kilowatts in areas within the water depth of 5 to 25 meters in the offshore, and there are even more abundant wind resources in the far sea. The development of offshore wind turbines is limited by one of the conditions: the lack of professional installation ship resources, and the high cost and risk of offshore construction. The state pays close attention to the development of of...

AI Technical Summary

Problems solved by technology

The wind turbine platform often needs to be repaired and maintained. However, due to the wind and waves at sea, it is very dangerous for people to go from the ship to the platform. It is very necessary for the offshore compensation platform to safely transport personnel and equipment from the ship to the wind turbine platform.

[0003] At present, the offshore boarding system is blank in China. We have related active wave compensation technology for offshore floating drilling platforms and offshore lifting equipment, mainly for the effect of wave changes on the speed of the lifting equipment during the lifting process of offshore loads. Control, and then realize the compensation of sea waves, the degree of freedom controlled by it is less, usually a single degree of freedom; it seriously affects the safety of boarding personnel when boarding at sea
