摘　　要：半潜式钻井平台是深海油气资源开发的重要装备之一。具备锚泊作业能力的半潜式钻井平台锚链的携带量会引起平台装载工况的变化,从而影响平台的运动性能。为了确定上述影响的程度,采用Sesam软件对某深水半潜式钻井平台作业和生存工况下不同锚链携带量的运动性能进行计算和对比。结果表明:平台锚链携带量对其运动幅值、加速度值和静气隙影响较小。可为今后半潜式钻井平台设计及装载配置提供参考。The semi submersible drilling platform plays an important role in the develop ment of the deepwater oil resources.When the platforms carried different quantity of mooring chains,the loading conditions may be changed which might affect its motion performance.The hydrodynamic software Sesam was used to analyze the motion performance of a semi-submersible drilling unit carrying different quantity of mooring chains.The results show that the variation of mooring chains makes little influence on the motion amplitude,accelerations and air gap of the platform. The research results may provide good proposal to the design of a new platform.
