摘要
为了分析一种海洋工程结构物在波浪中的运动响应,以上海振华重工(集团)股份有限公司设计制造的用于铺设海底管道的深水起重铺管船及其托管架作为研究对象,采用AQWA软件对其进行水动力分析。先通过频域分析计算铺管船在规则波中不同浪向下的六个自由度运动,得到铺管船的运动响应幅值算子(RAO),然后通过时域分析计算托管架在铺管作业时所受到的波浪力载荷时程,为后续的托管架强度分析奠定基础。
To analyze the motion response of an offshore engineering structure in waves,the deepwater crane pipe-laying vessel and its stinger are selected by Shanghai Zhenhua Heavy as the research object,and carries out hydrodynamic analysis with AQWA software.Firstly,the six degrees of freedom motion of the pipe-laying vessel under different directions in regular waves is calculated through frequency domain analysis in order to obtain the motion response amplitude operator(RAO)of the vessel.Secondly,the time history of wave force on the stinger during pipe laying operation is calculated through time domain analysis,which lays a foundation for the subsequent strength analysis of stinger.
