Problems solved by technology
[0002] Offshore wind turbine power generation is one of the main power generation methods. Due to its large size, it usually needs to be installed separately. At present, jack-up installation ships are basically used for construction. Due to the high cost and relatively scarce quantity, the installation cost is relatively high. There are currently no other alternative construction methods

Embodiment Construction
[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingl...

The invention discloses an installation method of an offshore wind turbine, including S01. positioning of a crane vessel; S02. fixed installation of a fixed platform; S03. inversion of a main engine, a hub and accessories; S04. installation of a tower column; S05. installation of a main engine; S06. Assembly and installation of the impeller. The construction method makes full use of the construction of the fixed platform and the putting into use of the crane vessel, so as to relieve the pressure on the scarce resources of the jack-up installation vessel, and also effectively save the cost of investment. The fixed platform provides a more stable construction platform on the sea surface, which is less affected by the sea surface swell, and is beneficial to prolong the construction window period and reduce the difficulty of construction. The cooperation between the crane vessel and the crawler crane on the fixed platform completes the construction step by step in an orderly manner. By lifting and adjusting the installation of the tower, the main engine and the impeller, the construction process is safe, efficient and reliable, and the construction period is shortened.
Description
【Technical field】 [0001] The invention belongs to the technical field of offshore wind power construction, and particularly relates to an installation method of an offshore wind turbine. 【Background technique】 [0002] Offshore wind turbine power generation is one of the main power generation methods. Due to its large size, it usually needs to be installed in a split type. At present, jack-up installation ships are basically used for construction. Due to the high cost and the scarcity of quantity, the installation cost is high. There are currently no other alternative construction methods. [Content of the invention] [0003] In order to solve the existing problems existing in the background art, the present invention provides an installation method of an offshore wind turbine, which has low construction difficulty, high efficiency and saves construction costs. [0004] The present invention adopts following technical scheme: [0005] An installation method for an offshor...
