Abstract: During the thermal launch operation of offshore launch platforms/ships, they will be subjected to the combined effects of rocket impact, wind, waves, and currents. Due to different arrangements of mooring systems, the motion response and mooring stress state of offshore launch platforms/ships are affected, which in turn affects the safety of the platform/ship-arrow. Therefore, this article explores the mooring arrangement of offshore launch ships under the coupling of multiple factors, including the arrangement of mooring point positions and changes in mooring line lengths, and their effects on the motion response and mooring stress state of offshore launch ships. Research has found that placing the mooring point below the waterline of the launch vessel and appropriately increasing the length of the mooring line will be more conducive to the conduct of offshore launch operations, providing technical references for the future layout of offshore launch vessel mooring systems.

摘要： 海上发射平台/船在进行热发射作业过程中,会受到火箭冲击和风、浪、流的联合作用。由于系泊系统的布置方式不同,海上发射平台/船的运动响应与系泊的应力状态均会受到影响,进而影响到平台/船-箭的安全,因此该文探究了多因素耦合作用下的海上发射船系泊布置方式,包括系泊点位置布置和系泊线长度变化对海上发射船运动响应和系泊应力状态的影响。研究发现将系泊点置于发射船水线以下以及适当增加系泊线的长度,将更加有利于海上发射作业的进行,为今后的海上发射船系泊系统布置提供技术参考。
