Marine fan integrated setting system

Abstract

The invention discloses a marine fan integrated setting system in the technical field of ocean engineering. The system comprises an installation ship, a portal frame, a precise positioning system, an ascending and descending system and a fastening device, wherein the portal frame is positioned at the head and stern of the installation ship and connected with the precise positioning system; the precise positioning system is arranged on a cross beam of the portal frame and connected with the ascending and descending system; and the ascending and descending system and the fastening device are arranged on a positioning beam of the precise positioning system respectively. After a fan is completely hoisted onshore, the fan is integrally transported to a marine wind power station by the wind power installation ship and set. Large hoisting equipment and other ships except a tugboat do not need to be used in the marine setting process. The precise positioning system and the ascending and descending system are arranged on the portal frame, the system is simultaneously provided with the fastening device for a transport state, and pile legs are driven to the seabed in a setting state, so thatstability and reliability in the whole fan transport and setting process are ensured.

Description

technical field [0001] The present invention relates to a device in the technical field of marine engineering, in particular to an integrated installation system for offshore wind turbines. Background technique [0002] The offshore wind turbine setting system is a system for setting wind turbines in place in harsh marine environments. In recent years, the development of offshore wind farms is in the ascendant. As a new form of wind energy, offshore wind energy has the advantages of low turbulence intensity, stable dominant wind direction, saving land resources, stable wind energy, no noise and landscape pollution. However, complex conditions such as wind, waves and drift ice in the marine environment have also brought many difficulties to the development of offshore wind power. Among them, the high cost of setting up links has become the biggest obstacle to the large-scale development of offshore wind farms. [0003] At present, the most commonly used offshore wind turbin...

Problems solved by technology

[0005] However, the limitation of this existing technology is that, on the one hand, no fastening device is installed above the center of gravity of the wind turbine during the overall transportation and installation of the wind turbine; Precise positioning, the movement of the barge in the floating state will affect the precise positioning

The above two aspects will lead to very high requirements on weather and sea conditions in transportation settings, which will seriously affect the time available for construction
