针对某深水半潜式钻井平台,为其设计 1 套多点扩展式锚泊系统。采用数值方法计算船体与系泊系统耦合动力响应,并通过水池模型试验对计算结果进行验证。结果表明,在钻井作业与生存工况下该平台的最大水平偏移与系泊张力均满足规范要求。通过计算结果与试验结果的对比发现,由于水池试验采用等效截断方法低估了系泊缆绳本身的质量惯性与所承受的流体载荷,导致系泊张力的计算结果略大于实验结果。
A multi-point mooring system is designed for a semi drilling platform in deepwater, and the coupled dynamic response of the hull and mooring system are obtained using numerical method and verified by model test. The result shows that the maximum horizontal offset of the vessel and the tension in cable can satisfy the requirement of the design criterion under drilling operation and survival condition, and because the equivalent truncated method which are adopted in the model test underestimate the mass inertia characteristic of the cable and the liquid load which act on it ,the tension result from the numerical process are larger than that of model test.
