| 摘 要： | 针对远海浮式结构物与供应船进行旁靠作业时,水动力干扰、两船的相对运动、旁靠系缆系统和护舷系统的受力特征等问题开展研究。建立各船的有限元模型,设计出两船旁靠连接缆系统,选取合适的系泊缆和护舷参数。研究表明:浮式结构物和供应船的横荡、纵荡方向存在一定的同步性或跟随性,幅值相差不大,其它方向的运动并不存在明显的同步特征;供应船的各自由度运动幅值均比浮式结构物偏大;旁靠护舷的受力时历出现了明显的低频效应,说明护舷的受力较大程度上受船体低频慢漂运动的影响;浮式结构物对供应船的水动力干扰较大,当浮式结构物在供应船的上风位置时,表现为屏蔽效应,供应船的运动较小;在其背风位置时,运动加剧,出现多次共振、峰值放大现象,供应船对浮式结构物的水动力性能几乎无影响,因此,供应船从浮式结构物的下风口一侧靠泊作业将更有利于船舶的安全性能。这些研究结论可为实际工程操作提供参考。

| Abstract: | The hydrodynamic interference, relative motion, side by side mooring and fender system forces are investigated respectively as the supply ship operates side-by-side with the Offshore Floating Structures. The FEM models of two ships are created. The side by side mooring system is designed in preliminary. In addition, suitable parameters of mooring lines and fenders are selected. It indicates that a good identity exists in the motion of sway, surge between two ships. But the identity of the other directions is not obvious. The motion magnitude of each DOF on the supply ship is relatively large. The fender forces show low frequency effect, which indicates that the low frequency drift motion of ship influences the fender forces to a large extent. Furthermore, hydrodynamic interference from the Offshore Floating Structures to supply ship is large. Shielding effect is much obvious as the Offshore Floating Structures are at the upwind side of the supply ship, and vessel motion is quite small. On the contrary, as the Offshore Floating Structures are at the leeside, the motion of the supply ship increases. The phenomenon of resonance and peak amplification on RAO appears. The supply ship has no effect on the hydrodynamic performances of the Offshore Floating Structures. Therefore, it is relative safe as the supply ship berths and operates from the leeside of the Offshore Floating Structures. The conclusions would provide a valuable reference for actual engineering operation. |
