Novel offshore wind turbine integral transportation and installation device and method

Abstract

The invention discloses a novel offshore wind turbine integral transportation and installation device and method. The novel offshore wind turbine integral transportation and installation device comprises a ship body, an engineering pile and a wind turbine, and is characterized in that a bow landing structure used for being connected with an adjusting device arranged on the outer side of the engineering pile is arranged at the front end of the ship body, a wind turbine fixing tower used for loading the wind turbine is arranged in the middle of the ship body and extends to the position above thebow landing structure, and a stern supporting structure used for keeping the ship body balanced is arranged at the tail end of the ship body. The installation method based on the novel offshore windturbine integral transportation and installation device comprises the three steps of wind turbine boarding, wind turbine transportation and wind turbine installation. The wind turbine is integrally transported and mounted, so that the efficiency is improved, the requirement of an operation window is reduced, and meanwhile, the cost of mounting engineering is reduced by modifying an old ship.

Description

technical field [0001] The invention belongs to the technical field of offshore wind turbine technology, and in particular relates to a novel offshore wind turbine overall transportation and installation device and method. Background technique [0002] Compared with the construction of wind farms on land, the construction of offshore wind farms has to face a more complex and harsh environment. Offshore operations are more difficult to construct and have a shorter operating window, which greatly increases the cost and construction period of offshore wind turbine development. At present, the development of offshore wind turbines generally adopts step-by-step installation, that is, the basic offshore construction is carried out first, and then the tower, machine head and fan blades are installed. This method increases the time for offshore operations and has higher requirements for the operation window. In addition, the traditional installation requires the construction of an o...

Problems solved by technology

[0002] Compared with the construction of wind farms on land, the construction of offshore wind farms has to face a more complex and harsh environment. Offshore operations are more difficult to construct and the operation window is shorter, which greatly increases the cost and construction period of offshore wind turbine development.

At present, the development of offshore wind turbines generally adopts step-by-step installation, that is, the basic offshore construction is carried out first, and then the tower, machine head and fan blades are installed. This method increases the time for offshore operations and has higher requirements for the operation window.

In addition, the traditional installation requires the construction of an offshore installation platform and the use of large-scale special equipment, which increases the cost of the installation project
