    摘要:

    为进一步提高海上浮式风电场的系泊效率和经济效益,本文以NREL 5-MW OC3-Hywind spar浮式风机为示范研究对象,提出了一种双共享系泊的设计方法,即风电场中相邻风机之间同时共享系泊线和锚点,并对双共享系泊系统进行了动力响应分析以及成本评估,目的为双共享方法在海上风电场中的应用提供参考。结果表明:共享线的布置导致共享线系统在纵荡运动方向的恢复刚度有所降低,对平台纵摇和垂荡运动的影响较小;不同方向环境荷载作用下,多线锚净荷载的大小基本不变并且小于最大单线锚荷载,方向与环境荷载方向基本保持一致;对于试点规模风电场的系泊成本统计结果表明,采用双共享系泊的方式可使系泊总成本降低32.84%。

    Abstract:

    In order to further improve the mooring efficiency and economic benefits of offshore floating wind farm, this paper takes NREL 5-MW OC3-Hywind spar floating fan as the demonstration object and proposes a design method of dual-shared mooring, that is, adjacent FOWTs in the wind farm share mooring line and anchor at the same time. In order to provide reference for the application of dual-sharing method in offshore wind farms, the dynamic response analysis and cost evaluation of dual-sharing mooring system are carried out. The results show that the distribution of shared lines reduces the mooring restoring stiffness of the system in the surge motion direction, and has little effect on the platform"s pitch and heave motion. Under environmental loads in different directions, the net load of multiline anchors is basically constant and less than the maximum single-line anchor load, and the direction is basically consistent with the direction of environmental loads. The statistical results of mooring cost for pilot scale wind farm show that the mooring cost can be reduced by 32.84% by using dual-shared mooring method.
