养殖工船海上旁靠补给系统设计及水动力性能

Design and Hydrodynamic Performance of Offshore Side-by-Side Replenishment System for Aquaculture Ship

随着深海养殖技术的发展和应用,补给船旁靠养殖工船进行补给作业受到越来越多的关注。针对海上单点单锚形式的养殖工船设计一种旁靠补给作业系统,建立水动力耦合模型,基于多浮体水动力学和全耦合时域法研究其水动力性能。研究表明:由于两船存在一定尺度差,波浪入射方向对补给船运动响应有一定影响,补给船在旁靠作业时有艉离的趋势。研究结果为实际工程提供设计理论依据。

With the development and application of deep-sea aquaculture technology,more and more attention has been paid to the side-by-side replenishment operation of the supply ship.The side-by-side replenishment operation system is designed for a single-point single-anchor aquaculture ship at sea,and a hydrodynamic coupling model is established.The hydrodynamic performance is studied based on multi-floating body hydrodynamics and fully coupled time-domain method.The research shows that due to the scale difference between the two ships,the incident direction of the wave has a certain influence on the motion response of the supply ship,and the supply ship has a tendency to leave the stern when it is working on the side.The research results provide a theoretical basis for practical engineering design.
