单点系泊深海养殖工船水动力性能

Hydrodynamics of Deep-Sea Aquaculture Vessel with Single Mooring System

为研究更加适合于深海养殖网箱工船的系泊方案,基于时域耦合理论,使用SESAM软件建立深海养殖网箱工船船体,在DeepC中建立系泊系统的耦合分析模型。根据系泊缆线布置方式的不同,对组式系泊和均布散射系泊进行对比分析。从船体的运动响应和系泊缆的张力两个方面,对比分析在不同浪向角和多种波浪载荷下的系泊性能。结果表明,对于深海养殖网箱工船采用组式单点悬链线系泊更为合理,养殖工船的纵荡和横荡运动响应受入射角影响较为明显,系泊缆线的布置方式对于系泊缆线张力影响较大。

In order to get the mooring scheme more suitable for deep-sea aquaculture cage vessel,based on the time-domain coupling theory,the hull of deep-sea aquaculture cage vessel is established by SESAM software,and the mooring coupling analysis model is established in DeepC.According to different arrangements of the mooring lines,comparative analysis of the grouped spread mooring and equal spread mooring is carried out.From the hull motion response and mooring line tension,the mooring performance under different incidence angles and various wave loads are compared and analyzed.It is indicated that it is more reasonable to adopt single-point grouped spread catenary mooring for deep-sea aquaculture cage vessel.The sway and yaw motion response of the aquaculture vessel is sensitive to the incidence angle.The mooring line tension is more related to the arrangement of the mooring lines.
