Three-legged installation ship specially for blade replacement of offshore wind turbine

Abstract

A three-legged installation ship specially for blade replacement of an offshore wind turbine belongs to the field of marine engineering. The invention aims to solve the problems of high cost of an existing installation ship used for wind power equipment and long maintenance time of the wind power equipment. The three-legged installation ship comprises a hull, operation and maintenance installationship pile legs, a wind power generation blade hoisting frame and a driving control room, wherein the hull is of an axisymmetric structure; the central axis of the hull is arranged along the length ofthe ship; the hull is provided with the three operation and maintenance installation pile legs; the three operation and maintenance installation pile legs comprise a first operation and maintenance installation pile leg positioned on the central axis of the bow of the hull, a second operation and maintenance installation pile leg and a third operation and maintenance installation pile leg; the second operation and maintenance installation pile leg and the third operation and maintenance installation pile leg are positioned on two sides of the central axis of the stern of the hull; the wind power generation blade hoisting frame is positioned at the stern of the hull; and the driving control room is positioned at the bow of the hull. The operation and maintenance ship disclosed by the invention has the advantages of greatly reducing the size, greatly reducing the cost, significantly improving the speed, realizing low rent and realizing timely allocation and transportation.

Description

technical field [0001] The invention relates to a special ship for changing blades of an offshore wind power generator, which belongs to the field of marine engineering. Background technique [0002] Offshore wind power generation is a new type of wind power generation technology that uses offshore wind resources to generate electricity. Under the increasingly severe situation of land resources, all countries have turned their attention to sea areas with huge wind resources. As a typical case of renewable energy applications, offshore wind power has already It has been widely concerned and promoted by countries all over the world. Many European countries have established multiple offshore wind power plants with huge scales. China's coastal coastline of thousands of kilometers from north to south contains huge wind energy. The country has already started this field. development and utilization engineering. [0003] In offshore wind power generation technology, wind power fac...

AI Technical Summary

Problems solved by technology

[0003] In offshore wind power generation technology, wind power facilities and equipment are an important part of the wind power industry, as well as the foundation and guarantee for the development of the wind power industry. However, after a period of operation of wind power facilities and equipment, parts need to be repaired or even replaced, especially for wind blades. Replacement is the most difficult. The existing technology uses wind power installation ships to complete the maintenance of offshore wind power facilities and replace wind blades. However, this type of wind power installation ship is expensive and rents high. At the same time, due to the high cost of wind power installation ships, the number of them is limited, resulting in transportation Increased time for wind power installation ships to carry out maintenance of wind power facility equipment
