Problems solved by technology
[0004] Crane ships are very dependent on weather and wave conditions, which is unfavorable for controlling the construction period
Because the non-self-propelled self-propelled platform has no self-propelled capability, it needs to be towed by a tugboat, so it is inconvenient to move between different wind turbine installation points, and it must meet the weather and other related requirements when using it, so the economy is poor
The third generation of wind power installation equipment - the self-propelled self-elevating offshore wind power installation ship is much less affected by weather and sea conditions, but the cost is high and the efficiency is low

Embodiment Construction
[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] The invention provides a mother-child installation ship, which is composed of a U-shaped mother ship and a catamaran-shaped daughter ship, such as figure 1 As shown, the mother ship includes a U-shaped hull 1, the surface of the U-shaped hull 1 is provided with a sliding track system 4, the fan 3 is placed on the sliding track system 4, and a rotating lifting system 5 is installed on the periphery of the fan 3. First trusses 2 are installed on the four corners of the hull 1 . like figure 2 As shown, the sub-ship includes two single hulls 6 and a connecting body 10 connecting the two single hulls 6. A second truss 9 is installed on the connecting body 10, and a crane platform 8 is installed on the top of the second truss 9. The crane platfo...

The invention discloses a parent-subsidiary mounting ship and application thereof to offshore wind turbine mounting. An offshore wind turbine mounting method is implemented by using the parent-subsidiary mounting ship and comprises the following steps: 1) enabling a main ship to reach a working area, dropping down pile legs, and release a secondary ship; 2) powering on a sliding track system, enabling a wind turbine to move to a single ship of the secondary ship along a sliding track system, powering on a rotating lifting system, and transferring the wind turbine to a connecting body of the secondary ship; 3) finally temporarily sailing the secondary ship, and mounting the wind turbine to an appointed site by using a hoisting machine on a hoisting machine platform with a positioning system, thereby completing mounting of the wind turbine. By adopting the parent-subsidiary mounting ship, the wind turbine transportation capability and the mounting speed can be increased.
Description
technical field [0001] The invention relates to the field of offshore wind turbines, and more specifically, to an installation method for offshore wind turbines based on a mother-child type installation ship. Background technique [0002] At present, the installation of offshore wind turbines in the world can be mainly divided into offshore overall installation method and offshore segmented installation method. The offshore equipment used for installation mainly includes offshore floating cranes, offshore platforms and special installation platforms for offshore wind turbines. [0003] The main equipment to complete the installation of offshore wind turbines includes a crane ship, a self-propelled ship with positioning legs, a self-propelled lifting platform and a self-propelled self-propelled self-propelled fan installation ship. Which installation ship to use depends on factors such as water depth, wind and wave conditions, and lifting capacity. [0004] Crane ships are ...
