Research on Ship Resources of Megawatt-Level Offshore Wind Turbine Foundation
In the parity era,offshore wind power development will give priority to deep sea,which requires large construction ships with strong wind and wave resistance,so higher ship cost is needed.Based on a far-reaching offshore wind field in Guangdong province,a study was conducted on the adaptability of the floating crane from lifting height and weight.Combined with the basic design parameters of the subsequent megawatt-level wind power project,the development trend of the basic parameters of the megawatt-level wind turbine in the future is discussed.According to the simulation model theory,different ship combinations are selected,and a diversified economic model of ship selection is proposed.The results show that when the weight of the jacket is less than 3,200 tons,the single ship is used for pile sinking construction and jacket hoisting.When the weight of the jacket is greater than 3,200 tons,the double ship combination method is used to pile sinking and jacket hoisting,which can effectively reduce the foundation construction cost of offshore wind power projects,and provide a reference for the resource selection of subsequent megawatt-level wind turbine foundation floating crane.
