Problems solved by technology

However, the lifting capacity of the crane ship is required to be large. In the modular installation, the fan base is first hoisted, and then the tower is hoisted. The engine room is then equipped with hubs, fan blades, and the number of hoistings is large. Correspondingly, it is greatly affected by wind and waves, and the construction efficiency is low. However, it is required Cranes with small lifting capacity

Embodiment 1

[0031] Fan 50 is integrally installed, and the ship of the present invention equipped with fan 50 equipment arrives at the installation site, and the installation operation of fan 50 can be started. The operation ship equipped with fan 50 of the present invention arrives near the pile foundation that has been laid, and throws off the hull Fore and tail end work anchor 22, then tighten up or loosen the anchor cable 24 that casts an anchor so that the bow of the catamaran enters the pile foundation and is positioned correctly, so that the crane 30 sling center is aligned with the pile foundation centerline. Tighten each anchor to fix the ship's position, loosen the anchor cable, take back the upper and lower clamps, put down the sling of the crane 30 to make the fan 50 assembly fall on the pile foundation, and the installation is completed. After the fan assembly is installed, put away the anchors, start the full-turn thruster 12 at the tail, propel the front side and turn around...

Embodiment 2

[0033] Modular installation fan or assembled fan, once the overall transportation and installation cannot be carried out due to the limitation of site conditions, and the split modular installation is adopted, it needs to use the full-slewing crane 32 to realize it. In the above situation, for example, the installation site is far away from the port wharf. After economical argumentation, it is found that it is not as good as transporting multiple (10 or more) fan assemblies at a time by a transport barge to transport one complete machine each time from the wharf to the construction site. It is economically more efficient to install all components modularly at the fan installation.

[0034] The way to assemble the wind turbine 50 is to use the azimuth crane 32 on the crane 30 to carry out.

[0035] First throw out the bow and tail working anchors to fix the ship's positioning. Start the full-slewing crane 32 to rotate the crane 30 and the lifting arm to the barge equipped with...

Abstract

The invention discloses a self-propelled marine wind-power engineering operation boat capable of operating by sitting on the sea bed. The operation boat comprises two boat units, anchoring systems and a hoist, wherein the anchoring systems are disposed at boat stems and boat sterns. The two boat units are connected through a connecting bridge, the hoist is disposed in the middle of the connecting bridge and on a hoist frame, side propellers are mounted at the front ends of the two boat units, full-rotation propellers are mounted at the sterns of the two boat units, and the hoist is a full-rotation hoist. The self-propelled marine wind-power engineering operation boat is fine in rolling resistance, thereby rolling caused by sea waves, winds and tides when the operation boat operates under the marine environment is low, affection on hoisting and mounting operations can be reduced maximally, and operation efficiency can be improved. Hoisting can be completed at one time as hoisting on lands. By the aid of the full-rotation propellers mounted at the sterns of the boat units, the self-propelling function is added into an operation boat without the self-propelling function, and voyage and dispatching of the self-propelled marine wind-power engineering operation boat can be realized without a tugboat.

Description

technical field [0001] The invention relates to an engineering operation ship, in particular to an offshore wind power engineering operation ship capable of self-navigation and capable of sitting on the bottom. Background technique [0002] One of the main tasks in building an offshore electric farm is the installation of wind turbines. [0003] To install this equipment, piling operations must first be carried out at sea, so that this equipment is located on the foundation formed by piling; to drive pilings, a special offshore piling ship is required, and such offshore piling ships are generally non-autonomous. The ship needs to be towed to the work site by tugboat. After the ship is in place, the ship needs to be anchored and positioned, and a special anchor ship is needed to complete this work; the generator set is transported from the port wharf to the construction site by transport barge and tugboat. After the equipment is transported to the installation site on the co...
