| 摘 要： | 半潜式平台是海洋工程领域重要的浮式装置,采用直接计算法对某半潜式平台结构的屈曲强度进行了评估.首先,对半潜式平台结构进行有限元模型化,然后根据海况不同将静水、正常工作和风暴自存三种状态划分为48种计算工况,利用频域内的三维线性水动力理论和设计波法计算半潜式平台在各工况下的波浪载荷,同时考虑各工况下的莫里森力、风载荷、锚链预张力、吊车载荷和钻井载荷等载荷,进而计算平台在48种工况下的应力响应.最后根据ABS规范对平台结构进行屈曲强度校核.结果表明,屈曲强度是平台结构强度的重要指标之一,应在设计时给予合理评价,评估结果可为半潜式平台设计开发提供参考.

| Abstract: | Semi-submersible platform is an important installation in ocean engineering. The buckling strength assessment of a semi-submersible platform structures was carried out based on direct calculation. First, the finite element model of the semi-submersible platform was built, then the still water state, operating condition and survival condition were categorized into 48 working conditions in term of different sea states, and the wave loads were computed by using linear 3D hydrodynamics associated with design wa... |
