排列间距对旧船改造的养殖工船的水动力影响分析

Analysis of Hydrodynamic Impact of Arrangement Spacing on the Breeding Working Ship Converted from Old Ships

基于水动力分析软件AQWA对并排系泊的由旧船改造的养殖工船进行数值模拟分析。通过改变相邻养殖工船的排列间距得到不同工况下养殖工船的运动响应,并将其与单船工况下的养殖工船的运动响应进行对比。结果显示,随着相邻养殖工船间的间距增大,最先迎浪的船舶在横摇方向上的运动响应几乎不受船间距的影响,而在垂荡方向上的运动响应则大于单船工况。出于船只安全考虑,并排系泊的养殖工船需对其垂荡运动进行额外校核。

This paper employs the hydrodynamic analysis software AQWA to conduct a numerical simulation analysis of the side-by-side mooring of converted breeding working ships.By varying the spacing between adjacent breeding working ships,the motion responses under different working conditions are obtained.These motion responses are then compared with those of a single breeding working ship.The results indicate that as the spacing between adjacent breeding working ships increases,the motion response in the roll direction of the first vessel facing the waves remains relatively unaffected,while the motion response in the heave direction is greater than that of a single vessel.Given these findings,it is recommended that,for the safety of the vessels,additional checks on the heave motion of side-by-side moored breeding working ships be performed.
