摘　　要：应用水动力计算软件AQWA,考虑随机波浪载荷及风、流载荷的作用,并考虑系泊缆的非线性动态特性和平台与系泊缆之间的相互影响,对第六代深水半潜式钻井平台水动力性能及极端工况的系泊性能进行数值计算。结果表明,平台在高频区域内运动性能表现良好,响应幅值很小;当环境力方向为60°时,平台的系泊缆张力和水平偏移最大,因而在设计系泊方案时要引起注意。The hydrodynamic software AQWA was used to analyze the performance of the hydrodynamic and mooring system of the semi-submersible platforms. The random wave loads, wind loads and current loads were considered, the nonlinear dynamic characteristics of mooring lines and the interaction of platform and mooring lines were considered to analyze the performance of the hydrodynamic and mooring system of semi-submersible platforms in extreme environment. The results showed that the motion performance of the platform is good when the wave frequency is in the high frequency region, and the mooring force and displacement are much serious when the direction reach 60 degree, which should be paid more attention..
