摘要 半潜式平台的锚泊系统通常能抵御5~10年一遇重现期的极端载荷,在台风来临时如何发挥锚泊系统的最大能力是平台作业者非常关注的问题。以某现役半潜式钻井平台为例,结合南海多个海域的典型环境参数,对不同水深、锚泊布置方案和锚链预张力下的锚泊系统能力进行了分析和对比,对影响锚泊防台能力的因素进行了总结,为半潜式平台科学防台避台提供了思路。 The mooring system of semi-sub mobile units can usually withstand the ocean environmental loads with return period of 5 or 10 years.How to optimize the mooring system in typhoon condition is a very important issue for platform operators.Taking an active semi-sub drilling unit as an example,combined with the typical environmental parameters of several areas in the South China Sea,the mooring system capability is analyzed and compared under different water depths,mooring arrangements and pre-tension settings.The factors affecting the ability of mooring against typhoon are summarized,which provide ideas for scientific typhoon protection for semi-sub unit.
