封闭箱体海洋水产养殖系统设计工序研究

Engineering investigation of design procedures for closed containment marine aquaculture systems

本文旨在研究海水环境中刚性封闭箱体水产养殖系统的潜在设计工序。封闭箱体水产养殖技术通过限制并操控养殖鱼类与外部水环境相互作用以将环境影响最小化。系统的箱体单元通常紧密排布并锚泊到海底。研究关注的地理区域在加拿大不列颠哥伦比亚省乔治亚海峡。本文研究了含多个单元的箱体水产养殖系统的设计构造。设计程序包括检验以下内容:当地环境条件;多个箱体单元上受到的阻力;波浪荷载;无阻尼升沉运动;锚泊设备组件;刚性控制结构的材料应力。还讨论了操作以及其它设计要素。初步研究结果表明波浪力是至关重要的。

The objective of this paper is to investigate potential design procedures for rigid, closed containment aquaculture systems deployed in the marine environment.In this context,closed containment is a term used to describe a range of aquaculture technologies that attempt to restrict and control interactions between farmed fish and the external aquatic environment,with the goal of minimizing impacts.The containment units are often closely spaced and moored to the seafloor bottom.The geographical area of interest is the Straits of Georgia,British Columbia in Canada.In this study,the design configurations of multiple closed containment systems are investigated.The design procedures include examining:(1) local environmental conditions,(2) drag forces on multiple containment units,(3) wave loading,(4) undamped heavemotions,(5) mooring gear components and (6)material stresses on a rigid containment structure.Operational and other design considerations are also discussed.Preliminary findings indicate that wave forces could be substantial.
