摘　　要：采用时域分析方法,研究某半潜式平台在不规则波作用下的动力响应特性。重点分析在不同浪向角情况下,平台系统有1根锚链缆发生断裂时,其运动谱与锚链缆张力谱的变化特性。研究表明,在该半潜平台遭遇恶劣海况时,一旦有某1根锚链缆发生断裂,则对整个平台系统的动力响应特性将是有很大影响的。Based on the coupled analysis method in time domain,the dynamic characteristics of a semi-submersible platform with mooring system in irregular waves were considered.The motion spectrums of the platform and the tension ones of the moorings were calculated and analyzed under the condition that one mooring line was broken in different wave directions.Results show that the effect of the case where one mooring line is broken on the dynamic characteristics of the semi-submersible platform in bad sea conditions will be remarkable.
