摘要
平价时代下,海上风电将以深远海发展为主,这就需要抗风浪能力强的大型施工船舶,为此需要更高的船舶成本.以广东某深远海风电场为例,从吊高和吊重两个方面对基础起重船的适应性进行了研究,并结合后续大兆瓦风电项目基础设计参数,探讨未来深远海大兆瓦风机基础参数的发展趋势.基于仿真模型理论,选择不同的船舶组合,提出船舶选择多元化经济模型.结果表明,当导管架重量小于3200 t时,采用单船进行沉桩施工和导管架吊装;当导管架重量大于3200 t时,采用双船组合方式,分别进行沉桩施工和导管架吊装,能够有效降低海上风电项目基础施工成本,为后续大兆瓦风机基础起重船的资源选择提供参考.
Abstract
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.
