Abstract: This paper optimizes the scheme of side-by-side mooring operation for a special SWATH. Through numerical simulation and model tests, we analyze relative motions, mooring line tensions, and fender loads between the SWATH and single-body ship, aiming to guide the side-by-side mooring operation. The results show that the displacement difference of SWATH significantly affects the horizontal motion of the barge and the motion of SWATH itself. Changes in wave direction have a notable impact on the horizontal motion of both ships. Under the same relative motion, short mooring lines and fenders bear large loads. Therefore, it is recommended to select optimal wave directions (e.g., head seas) and loading states for operations. Beam seas (90°) pose the highest risk due to excessive fender compression. The research provides references for the design and optimization of side-by-side operations between SWATH and ships.

摘要： 该文针对特殊线型的小水线面双体船海上旁靠的作业场景提出通过运动数值仿真以及实物模型试验,预报小水线面双体船与单体船过驳作业时,两船之间的相对运动与护舷受力情况,分析适宜旁靠作业的海况条件。结果表明,双体船的排水量差异对旁靠过驳船水平面运动和双体船自身运动均有较大影响,浪向的变化对两船的水平面运动有显著影响,在同样的相对运动下,两船之间的短缆和护舷承受较大的载荷,宜选择顶浪及合适的装载状态进行旁靠作业。研究成果可为双体船旁靠过驳作业方案及设计优化提供一定参考。
