摘要
基于静力学原理和规范要求,设计了一种搭载NREL 5 MW风机的V型半潜式平台,计算并验证了其结构完整稳性。结果表明平台设计优良合理,在工作工况和自存工况的各个倾斜轴下均能保证足够的结构稳性。自存工况时平台的最小许用重心高度为12.2 m,而实际重心高度为9.4 m,并未超出许用限值。值得注意的是,30°倾斜轴为平台危险轴,此时稳性相对较差,需要注意平台在此倾斜轴下的横倾运动。
Based on the principle of static mechanics and the IMO requirements,a V-type semi-submersible offshore platform equipped with NREL 5 MW wind turbine was designed,and its intact stability were calculated and verified.The results showed that the platform design is excellent and reasonable.The platform can ensure sufficient structural stability under both the operation condition and the survival condition for any inclination axis.The minimum allowable vertical center of gravity of the platform is 12.2 m during the survival condition,while the actual center of gravity is 9.6 m,which does not exceed the allowable limit.It is noted that the 30ºinclination axis is the platform's dangerous axis,for which the stability is relatively poor.It is thus necessary to pay attention to the lateral heeling movement of the platform under this inclination axis.
