Self-propelled and self-elevating wind power transportation and installation ship and installing method of wind turbine units

Abstract

The invention belongs to the field of oceanographic engineering and particularly relates to a self-propelled and self-elevating wind power transportation and installation ship. The self-propelled and self-elevating wind power transportation and installation ship comprises a hull, a cantilever beam, pile legs and a gear and rack lifting system. A plurality of wind turbine unit fixing bases are arranged on a deck of the hull along the longitudinal central axis, four trunks are arranged on the left side and the right side of the hull, a pile fixing frame is installed above each trunk, one pile leg is arranged in each trunk, penetrates through the corresponding pile fixing frame and the corresponding trunk and extends downwards, and racks are arranged on the front side and the rear side of each pile body; the cantilever beam is fixed to two pile fixing frames and provided with a longitudinal sliding device, and the longitudinal sliding device comprises a longitudinal sliding base and longitudinal sliding guide rails; four transverse sliding devices are installed in parallel between the two longitudinal sliding guide rails, each transverse sliding device comprises two transverse sliding devices, and a set of clamping claws is fixed to the tail end of each transverse sliding guide rail. The self-propelled and self-elevating wind power transportation and installation ship can independently finish wharf loading and transporting operation and installing operation in an appointed sea area for wind turbine units.

Description

technical field [0001] The invention belongs to the field of marine engineering, and in particular relates to a self-propelled self-elevating wind power transport and installation ship and a method for installing a wind turbine. Background technique [0002] Compared with onshore wind power, offshore wind power has the advantages of abundant resources, high wind speed, stable wind direction, no occupation of land resources, small environmental impact, and suitable for large-scale development. The eastern coast of my country has a vast sea area with a water depth of 5-20m, and the available wind energy at a height of 10m is about three times that of land, and it is relatively close to the eastern coastal cities that require a large amount of electric energy. However, the transportation, installation and construction of offshore wind turbines are difficult, and the requirements for the strength and reliability of wind turbines are relatively high, which puts forward higher req...

AI Technical Summary

Problems solved by technology

[0004] The installation of offshore wind turbines requires high installation accuracy, but many factors will affect the installation of wind turbines

On the one hand, the installation location of the offshore wind turbine has a relatively large positioning wind speed, and the pulsating wind load acting on the wind turbine during the hoisting process will cause the wind turbine to sway; on the other hand, the traditional installation ship is equipped with a jib crane, and the crane The boom has greater flexibility, and the installation of offshore wind turbines has a trend of deeper water and higher power units, which will increase the lifting capacity of the crane and cause greater deformation of the boom
