摘要： 深远海养殖工船作为一种新型的海洋作业平台以及养殖模式，受到海洋工程以及海洋养殖产业领域的广泛关注，针对中国对养殖工船的改装建造及其养殖运营尚缺少相关的技术经济论证系统，本文选取论证参数，利用线性回归方程建立改造散货船船型的主尺度模型，以养殖效果系数、投资回收期、净现值，建立经济模型，通过参数分析法对船型技术、经济多目标船型方案进行技术经济性能计算，择优选取方案，选取鱼价、养殖存活率、年养殖成本为不确定因素进行敏感性分析；基于技术经济论证模型，利用VB编程技术开发可用于养殖工船技术经济论证系统。通过模拟计算得出船型的载货量应大于3万t，鱼价应不低于61.4元/kg，存活密度应不小于36尾/m3。

Abstract:  As a new type of marine operation platform and aquaculture model, the deep ocean aquaculture engineering ship has received extensive attention in the field of marine engineering and marine aquaculture. At present, China still lacks relevant technical and economical verification systems for the refitting and construction of aquaculture engineering ships. In this paper, based on the argumentation parameters, the main scale model for reconstructing the bulk carrier ship type was established using the linear regression equation; the economic model was established with the farming effect coefficients, investment payback period, and net present value; the technical-economic performances of the ship type technology and economic multi-target ship type scheme were calculated by the parametric analysis method, thus to select the best scheme among them by comparison; sensitivity analysis was carried out on the uncertain factors such as the survival rate and the annual aquaculture cost. Thus VB programming technology can be used to develop a technical and economical demonstration system for aquaculture engineering ships based on the technology and economics demonstration model. Through the simulation calculation, the carrying capacity of the ship type should be more than 30,000 tons, the fish price should not be less than 61.4 yuan/kg, and the breeding density should not be less than 36fries/m3.
