摘　　要：为对作业水深超过200 m的大型深水导管架的海上施工设计方案进行分析,结合南海某新设计的深水导管架平台,基于MOSES软件模拟导管架的拖航和下水过程。对驳船的拖航稳性和运动响应进行分析计算,并研究浪向和驳船吃水深度对驳船与导管架联合体运动RAO的影响,结果发现:浪向对各自由度RAO幅值存在不同程度的影响;驳船吃水深度增加仅导致纵荡幅值减小。同时,对导管架下水的基本工况和初始下水参数的敏感性进行分析,得到驳船初始吃水和纵倾对下水过程的影响曲线,可看出在导管架下水过程中各项参数均符合规范的要求。研究结论可供深水导管架海上施工方案的设计和优化参考。To analyze the offshore construction design scheme for large deepwater jacket platforms with operating depths exceeding 200 m,combined with a newly designed deepwater jacket platform in the South China Sea,the towing and launching process of the platform is simulated based on MOSES software.Analysis and calculation are conducted on the towing stability and motion response of the barge,and the effects of wave direction and barge draft on the RAO of the barge jacket joint are studied.The results show that wave direction had varying degrees of influence on the RAO amplitude of each degree of freedom,and an increase in barge draft only resulted in a decrease in surge amplitude.At the same time,an analysis was conducted on the basic operating conditions and sensitivity of initial launching parameters for the jacket platform,and the influence curves of the initial draft and longitudinal inclination of the barge on the launching process are obtained.The results show that all parameters meet the requirements of the specifications during the launching process.The research conclusion can provide reference for optimizing the design of offshore construction schemes for deepwater jacket platforms.
