The invention belongs to ocean engineering, and particularly relates to a novel OC4-DeepCWind semi-submersible platform which is used for solving the problems that a cylindrical upper stand column of an existing OC4 platform is large in wave load, overweight in structural weight, insufficient in stability and the like under deep water and severe sea conditions. According to the scheme, an upper stand column of an existing OC4 platform offset column is optimized into a rounded triangular prism, dynamic responses of floating bodies before and after optimization are basically the same, and the dynamic responses of the floating bodies are judged to be basically the same according to set conditions. After the scheme is optimized, not only is the weight of the structure reduced, but also the wave force is more uniformly dispersed on the surface and the wave climbing effect is weakened through the geometrical shape of the rounded triangular prism, so that the impact load of waves on the platform is reduced, the anti-wave capability and the stability of the platform are improved, the shaking frequency of the platform is reduced, and the service life of the structure is prolonged.

    本案属于海洋工程,具体涉及一种新型OC4‑DeepCWind半潜式平台,用于解决现有OC4平台的圆柱形上立柱在深水和恶劣海况下面临波浪载荷大、结构重量偏重和稳定性不足等问题。本案通过将现有OC4平台偏置柱的上立柱优化为圆角三棱柱,并且使优化前后浮体动态响应基本相同,所述浮体动态响应基本相同通过设定条件判断。本方案优化后不仅减轻了结构重量,而且通过圆角三棱柱的几何形状,使波浪力在表面更均匀地分散,削弱波浪爬升效应,进而减少波浪对平台的冲击载荷,提高平台的抗波浪能力和稳定性,减小了平台的晃动频率,延长了结构的使用寿命。
