SIMULATION RESEARCH ON AGGREGATE INSTALLATION PLANNING FOR OFFSHORE WIND TURBINES INSTALLATION BASED ON DISCRETE NUMERICAL ANALYSIS
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.
