基于离散数值分析技术的海上风电机组安装施工规划模拟研究

SIMULATION RESEARCH ON AGGREGATE INSTALLATIONPLANNING FOR OFFSHORE WIND TURBINES INSTALLATION BASED ONDISCRETE NUMERICAL ANALYSIS

海上风电机组安装主要包括多船舶联合施工、单船自运输安装施工两种方式。海上风电场建设中,风电机组安装施工费用占有较大比重,进行整体施工规划分析可以为宏观决策提供量化依据。鉴于此,采用离散数值分析模拟技术,以实际工程项目施工限制条件和风浪流数据为计算参数,对项目总工期和怠机时长等进行数值模拟,以比较上述两种模式的施工效率优劣。结果表明,相对航行距离在359.26 km前,单船模式施工累计耗时高于多船模式,超过该距离后,多船模式逐渐高于单船模式;多船模式怠机抵抗性能整体上优于单船模式。

The installation of offshore wind turbines relies on the multi-vessel construction method and the single-vessel mode.Given the high capital investment cost of offshore wind turbines,construction planning analysis is crucial to make informed decisions.As a result,quantitative analysis on the efficiency of the above two modes is necessary.In this study,the discrete number analysis simulation technology is used to compare the efficiency of the two construction modes.The actual project construction restrictions and metocean data are used as calculation parameters to simulate the total project duration and delay time.The results show that the accumulative construction time of the single-vessel mode is higher than that of the multi-vessel mode before the relative sailing distance of 359.26 km,beyond which the multi-vessel mode becomes more efficient.Furthermore,the multi-vessel mode generally exhibits better anti-delay performance than the single-vessel mode.
