The invention improves the transportation capacity and the installation speed of the fan.

Description

Parent-subsidiary type installation ship and application thereof in offshore wind turbine installation
Technical Field
The invention relates to the field of offshore wind turbines, in particular to an offshore wind turbine installation method based on a parent-child type installation ship.
Background
At present, the installation of offshore wind turbines in the world can be mainly divided into an offshore integral installation method and an offshore sectional installation method. The offshore equipment used for installation mainly comprises an offshore floating crane, an offshore platform and a special offshore wind turbine installation platform.
The offshore wind turbine installation work is completed by mainly using a crane ship, a self-propelled ship with a positioning pile leg, a self-elevating crane platform and a self-propelling self-elevating wind turbine installation ship. The type of vessel used depends on the depth of the water, the wind and wave conditions, and the lifting capacity.
The crane ship is very dependent on weather and wave conditions, and is unfavorable for controlling the construction period. The non-self-propelled self-elevating platform needs to be towed by a tugboat because of no self-propelling capability, so that the platform is inconvenient to move among different fan mounting points, and the platform needs to meet the relevant requirements of weather and the like when in use, and has poor economy. The influence of weather and sea conditions on the third generation wind power installation equipment, namely the self-propelled self-elevating offshore wind power installation ship is reduced, but the cost is high and the efficiency is low.

In the scheme, the four corners of the ship surface of the U-shaped ship body are provided with the first trusses.
The invention also provides an application of the parent-child type installation ship, which comprises the installation of the offshore wind turbine, and the method for installing the offshore wind turbine comprises the following steps: 1) the primary ship is a tugboat, the secondary ship is positioned in a U-shaped ship groove of the primary ship, and pile legs descend to release the secondary ship after the primary ship sails to a designated sea area; 2) starting a sliding track system, moving a fan to a single hull of the sub-ship along the sliding track system, then starting a rotary lifting system, and transferring the fan to a connecting body of the sub-ship; 3) and finally, carrying out short-time navigation on the sub-ship, and installing the fan to a specified site by a crane on the crane platform by virtue of the positioning system to finish the installation of the fan.
Compared with the prior art, the invention has the following beneficial effects:
according to the novel primary and secondary fan installation ship designed by the invention, the primary ship is based on the U-shaped ship, the secondary ship is based on the catamaran, and the fan transportation capacity and the installation speed are improved by the common cooperation of the sliding track system, the rotary lifting system, the positioning system and the like.
