Offshore wind turbine installation method and installation system

Abstract

The invention belongs to the technical field of marine machinery, relates to an offshore wind turbine installation method and installation system and aims at solving the problems of large difficulty and the like during butt joint installation of a wind turbine in the prior art. A wind turbine comprises an engine room, a tower barrel and a blade. The installation system comprises a fan mounting ship; the fan mounting ship is provided with a rotating table which can swing between a horizontal position and a vertical position in a reciprocating manner; the rotating table is provided with a translation device capable of moving in the reciprocating manner in a horizontal direction; and the translation device is provided with a fastening device capable of fixing the engine room, the tower barreland the blade and a sliding rail capable of being aligned with a mounting base. For the offshore wind turbine installation method and installation system, when the tower barrel, the engine room and the blade are installed, the sliding rail is designed, so that shaking caused by a wind force during the installation process can be effectively avoided, the butt joint precision during installation iseffectively improved, the butt joint difficulty is lowered, the installation efficiency is improved, and the installation period is shortened.

Description

technical field [0001] The invention belongs to the technical field of marine machinery, and relates to an installation method and an installation system of an offshore wind motor. Background technique [0002] The hoisting method of the wind turbine refers to the hoisting method of the unit components, which is divided into two types: split hoisting method and integral hoisting method. Onshore wind farms usually have good operating site conditions, and at this stage, large crawler cranes or large truck cranes are basically used for separate hoisting. Offshore wind farms are limited by conditions such as sea climate, tides, waves, water depth, and seabed geology. Compared with the hoisting of onshore wind turbines, the situation is more complicated. Compared with the hoisting of onshore wind turbines, the hoisting of offshore wind turbines lacks a stable hoisting platform. The lifting equipment installed on the ship is easy to shake due to factors such as buoyancy, waves, a...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned device can improve the installation accuracy during alignment to a certain extent, the wire rope of the crane is prone to swing due to the influence of wind force during hoisting, especially when hoisting wind blades and other parts, the swing is relatively large, resulting in positioning during docking. Difficult, thus affecting the overall construction progress
