Offshore wind turbine operation and maintenance method, device and system

Abstract

The embodiment of the invention discloses an operation and maintenance method, device and system for an offshore wind generating set. The method comprises the steps that every time the preset time point is reached, the to-be-berthed position is confirmed according to the attribute information of the to-be-berthed position used for conforming an operation and maintenance mother ship, so that an operation and maintenance ship carried by the operation and maintenance mother ship departs from the to-be-berthed position, and operation and maintenance are carried out on the wind generating set including in an offshore wind plant used for providing operation and maintenance services for the operation and maintenance mother ship. According to the operation and maintenance method, device and systemfor the offshore wind generating set, the to-be-berthed position of the operation and maintenance mother ship can be conformed, then the operation and maintenance ship carried by the operation and maintenance mother ship can depart from the position where the operation and maintenance mother ship is berthed when operation and maintenance is carried out on the offshore wind plant, the operation and maintenance ship does not need to depart from a wharf, the operation and maintenance ship can avoid sandbanks and marine product aquiculture areas, and then the operation and maintenance efficiencyof the offshore wind plant can be improved.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, in particular to an operation and maintenance method, device and system for an offshore wind power generating set. Background technique [0002] At present, offshore wind power is in a period of accelerated development, and offshore wind farms have already reached a considerable scale. In the next few years, offshore wind farms will usher in a climax of construction, and the operation and maintenance of offshore wind farms will also enter a peak period. [0003] There are three main operation and maintenance methods for offshore wind farms: using small operation and maintenance ships, service operation and maintenance ships and helicopters for operation and maintenance. Due to the limitation of water depth, offshore distance and operation and maintenance cost of offshore wind farms, the operation and maintenance method of using service operation and maintenance ships and he...

AI Technical Summary

Problems solved by technology

There are a large number of shallow sandbars in the sea near the shore, and such sandbars are often located on the necessary channel from the wharf to the offshore wind farm, which seriously affects the operation and maintenance of the operation and maintenance ship, and affects the operation and maintenance of the offshore wind farm.

With the advancement of the development process of offshore wind farms, offshore wind farms will be farther and farther away from the shore, and the one-way trip time of operation and maintenance ships far exceeds the endurance time of offshore construction operations, and the safety is poor; in addition, small operation and maintenance ships have poor seakeeping Poor safety and security, which increases the risk of seasickness of operation and maintenance personnel and affects the safety of operation and maintenance personnel. At the same time, there are many mariculture areas on the channel from the dock to the offshore wind farm. When the operation and maintenance ship passes through such areas, it often occurs Ropes and fishing nets are entangled with the propeller, causing the downtime of the operation and maintenance ship, which will also affect the operation and maintenance of the offshore wind farm
