摘　　要：本文以一艘近海敷设驳为研究对象,使用Ansys建立了数值仿真模型,并利用AQWA软件对该对象进行频域分析,并在添加系泊缆后,进行了时域分析。研究表明,由空船工况转为载重工况对于其垂荡运动自由度有抑制作用。无论空船工况还是载重工况,横摇的Motion RAO的变化都是最快的。在敷设驳进行铺设电缆作业时,其纵荡方向的运动响应会有明显增加。本文采用的系泊方式考虑了中间牵引绞车的工作方式,采用了五系泊缆的系泊,经计算可知满足系泊要求。This paper takes on offshore barge as the resarch object,establishes a numerical simulation model using Ansys,carries out frequency domain analysis using AQWA software,and carries out time domain analysis after adding mooring cables.The results show it can restrain the degree of heave motion.Whether in empty or load condition,rolling Motion RAO changes the faster.When laying barge tolay cable,the motion response of surge direction will increase obviously.The mooring mode adopted in this paper takes into account the working mode of the intermediate traction which and adopts the mooring mode of five mooring cables.The calculation shows that it meets the mooring requirements.
