Construction method and special transport and installation ship for marine transport and installation of wind-driven generator

Abstract

The invention relates to a construction method and a special transport and installation ship for the marine transport and installation of a wind-driven generator. The special transport and installation ship adopted in the construction method comprises a ship body, wherein the stem of the ship body is provided with an installation system and a ship body stem overlapping device; the installation system comprises an installation platform, a mounting bracket arranged on the installation platform and a jacking and fine tuning device, and the mounting bracket used for fixing the wind-driven generator in transport and installation processes; and the jacking and fine tuning device is used for positioning the wind-driven generator. According to the invention, the transport and installation ship isadopted to perform installation and integrates the functions of the marine transport and installation of the whole wind-driven generator, thus the marine transport and installation of the whole wind-driven generator can be directly performed without influences caused by wind waves; and a special transport ship is not required to be used for transporting the wind-driven generator to an installation site, and a marine platform or a giant hoisting machine on a special crane ship is not required to be used for installation thus the construction and use cost is low.

Description

technical field [0001] The invention relates to a method for offshore transportation and installation of a wind-driven generator, in particular to a construction method for integrally transporting and installing an offshore wind-driven generator by a special transportation and installation ship and a special transportation and installation ship. Background technique [0002] At present, there are two installation methods for offshore wind turbines, one is separate installation, and the other is overall installation. Among them, separate installation refers to the wind power generation on the base of the offshore wind turbine from bottom to top. The various parts of the wind turbine are installed together; the overall installation refers to the overall transportation of the wind turbine assembled on the shore to the installation site at sea, and then installed on the base of the offshore wind turbine. These two installation methods all need to use a special transport ship to ...

AI Technical Summary

Problems solved by technology

Due to the huge hull of offshore platforms or crane ships and the high cost of large-scale lifting machinery, the cost of using ships and installation machinery for wind turbine installation operations is relatively high, and with this installation process, the huge hull cannot be used in shallow water District homework

In addition, due to the high installation accuracy requirements of offshore wind turbines, when the crane ship is affected by wind and waves, the vertical and horizontal swings of the hull are relatively large, which cannot meet the installation accuracy requirements, and the installation is difficult and the construction period is long.
