Problems solved by technology

More importantly, in the above-mentioned traditional construction method, since the installed structure is in a fixed state, and the ship and the crane are in a floating state, the accuracy of construction and installation can only be guaranteed in an ocean environment where the wind current and wave current are very small.

Embodiment Construction

[0028] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0029] This embodiment discloses a method for installing an offshore wind power complete machine. The construction equipment involved in the method mainly includes a roll-on-roll-off ship 1 capable of carrying multiple complete wind turbines 4, a crane transport ship 2, and a wind turbine Install boat 3.

[0030] like figure 1 and figure 2 As shown, 10 wind turbines 4 are carried on the ro-ro ship 1, and each wind turbine 4 includes a wind tower, a wind turbine head and a wind blade. The wind turbine 4 is arranged in two rows on the hull deck of the ro-ro ship 1, and they are all located on the ro-ro transmission equipment on the deck. They are fixed during transportation, and can be rolled and hoisted in sequence during installation.

Abstract

The invention discloses an offshore wind power complete machine installation method. A roll-on-roll-off ship loaded with a fan complete machine, a crane transport ship provided with a ballast empty compartment and a fan installing ship provided with the ballast empty compartment take position; the crane transport ship is loaded so that the plug-in board of the crane transport ship is inserted in an inserting hole of the fan installing ship; deloading is conducted on the crane transport ship while the fan installing ship is loaded, the plug-in board and the inserting hole are clamped through a vertical bolt, and the crane transport ship and the fan installing ship are closely connected together; the fan complete machine is lifted through a lifting device of the crane transport ship and is installed at the upper portion of a bucket foundation fixed by the fan installing ship; integrated construction installation is conducted on the bucket foundation and the fan complete machine through a negative-pressure sinking installation construction method. By means of the method, the crane transport ship and the fan installing ship form an installing platform capable of associated operation, so that the lifting device lifts the fan complete machine to be installed to the bucket foundation and the operation is simple, installation accuracy is completely controllable, the construction window period needed is short, and construction installation effect and economic effect are obvious.

Description

technical field [0001] The invention relates to a construction method of an offshore structure, in particular to an installation method of an offshore wind power machine. Background technique [0002] At present, in offshore wind power projects, the installation of offshore wind turbines is generally divided into four parts: foundation, fan tower, fan head and fan blades, which are transported to the offshore construction location by a transport ship. The ship installs the fan tower, fan head and fan blades in sequence, and finally completes the debugging of the whole machine. [0003] The traditional construction method mentioned above requires a long window construction period, which increases the cost of the offshore construction team. More importantly, in the above-mentioned traditional construction method, since the installed structure is in a fixed state, and the ship and crane are in a floating state, the accuracy of construction and installation can only be guarante...
