Ship and method for transportation and installation of complete offshore wind turbine

Abstract

The invention discloses a ship and a method for transporting and installing a complete offshore wind turbine. The special ship for transporting and installing a complete offshore fan includes a transport barge, a fixed steel frame, and a mobile rigid frame. The main hull of the transport barge is equipped with Multiple self-elevating piles, multiple first fan hoop mechanisms are installed on the fixed steel frame, the movable steel frame is slidably arranged under the fixed steel frame, and the mobile steel frame includes the first outriggers arranged oppositely on both sides of the main hull With the second outrigger, the upper ends of the first outrigger and the second outrigger are provided with a supporting beam spanning, the middle part of the supporting beam is provided with a second fan hoop mechanism, and the lower end surface of the supporting beam is provided with a sliding track, and the sliding track There is a lifting mechanism on the top, a balance hanger is arranged under the support beam, a third fan hoop mechanism is arranged on the balance hanger, the lifting mechanism is connected with the balance hanger, and the stern of the main hull is provided with a fan installation notch. It can realize the overall transportation and installation functions of the fan at the same time, effectively reducing costs.

Description

technical field [0001] The invention relates to a special ship and method for transporting and installing an offshore wind turbine. Background technique [0002] At this stage, the installation of offshore wind turbines at home and abroad generally adopts a split installation method. Most of the installation ships are self-elevating offshore operation platforms, and there are also a small number of engineering cases where wind turbines are installed integrally. The installation of offshore wind turbines is greatly affected by marine hydrometeorological conditions. The main influencing factors are water depth, wind, waves, rain, fog, thunderstorm and tide, etc. The main disadvantage of the split installation method of offshore wind turbines is that the offshore construction period is long and the construction risk is high; if the offshore wind turbine installation adopts the integral wind turbine installation method, then It can reduce the working time at sea and reduce the u...

[0002] At this stage, the installation of offshore wind turbines at home and abroad generally adopts a split installation method. Most of the installation ships are self-elevating offshore operation platforms, and there are also a small number of engineering cases where wind turbines are installed integrally. The installation of offshore wind turbines is greatly affected by marine hydrometeorological conditions. The main influencing factors are water depth, wind, waves, rain, fog, thunderstorm and tide, etc. The main disadvantage of the split installation method of offshore wind turbines is that the offshore construction period is long and the construction risk is high; if the offshore wind turbine installation adopts the integral wind turbine installation method, then It can reduce the working time at sea and reduce the uncontrollable risks caused by natural factors. Large-scale crane ships are often used at home and abroad for the installation of integral wind turbines. At the same time, they are equipped with dedicated wind turbine transport ships and tugboats. high cost
