Offshore wind turbine set installation ship device and installation method thereof

Abstract

The invention discloses an offshore wind turbine set installation ship device and an installation method thereof. The installation ship device comprises a control system, an installation ship, a craneand an underwater hydraulic system, wherein the installation ship comprises support pile legs, a wind turbine set installation base, a transportation fixing frame and a rotary platform, and the underwater hydraulic system comprises a hydraulic piling device and a hydraulic lifting device. When a wind turbine set is installed, an underwater hydraulic piling hammer is adopted for piling, and the hydraulic lifting device is used for installing the pile legs and lifting a ship body. The transportation fixing frame comprises two frame bodies which are arranged on the left and right sides of the installation ship and are parallel to each other, and when a draught fan is loaded, the two frame bodies slide to the middle position along a transverse track to lock the draught fan and keep the draught fan stable. An anti-tilting module is arranged among the rotary platform, a crane base and the ship body, so that the crane is maintained at a horizontal stable state when rotating. The offshore wind turbine set installation ship device integrates various functions of transport ships, offshore operation platforms, hoisting ships and offshore supply ships, can avoid influences of wind and waves and run independently, and is low in cost and high in practicability.

Description

technical field [0001] The invention relates to the technical field of offshore wind turbine installation, and relates to an offshore wind turbine installation ship device and an installation method thereof. Background technique [0002] Wind power generation is one of the new energy development projects that countries in the world have paid close attention to in recent years, and its development speed is very fast. There are more and more construction projects for offshore wind farms, and the difficulty is increasing. [0003] The installation of offshore wind turbine equipment has higher and higher requirements for the installation platform of wind turbines. The usual practice is to first transport the installation room to a specific location with a transport ship, and then use a crane ship to locate and install it, and at the same time, cooperate with a living supply ship. The whole process uses many ships and is inefficient. In order to solve various difficulties in th...

AI Technical Summary

Problems solved by technology

Many ships are used in the whole process and the efficiency is low. In order to solve various difficulties in this situation, offshore wind turbine installation ships came into being

[0004] However, most of the wind turbine installation ships in the prior art are complex in structure, high in cost, and have single functions, resulting in poor practicability and low marketability.
