Ship special for transporting and installing whole offshore wind turbine and method

Abstract

The invention discloses a ship special for transporting and installing a whole offshore wind turbine and a method. The ship special for transporting and installing the whole offshore wind turbine comprises a transporting barge, a fixed steel framework and a movable steel framework. A plurality of self-elevating piles are arranged on a main body of the transporting barge. The fixed steel framework is provided with a plurality of first wind turbine hooping mechanisms. The movable steel framework is arranged below the fixed steel framework in a sliding mode. The movable steel framework comprises a first supporting leg and a second supporting leg, wherein the first supporting leg and the second supporting leg are arranged on the two sides of the main body oppositely. Crossing supporting beams are arranged at the upper end of the first supporting leg and the upper end of the second supporting leg. A second wind turbine hooping mechanism is arranged in the middle of each supporting beam. A sliding track is arranged on the lower end face of each supporting beam and provided with a hoisting mechanism. Balance hangers are arranged below the supporting beams. Third wind turbine hooping mechanisms are arranged on the balance hangers. The hoisting mechanisms are connected with the balance hangers. A wind turbine installing notch is formed in the stern of the main body. The ship can transport and install the whole wind turbine and effectively reduce cost.

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
