在全球经济格局深刻调整与海洋资源开发加速的双重背景下，海洋养殖业正成为各国保障粮食安全、推动经济转型的重要战略领域。2025年，全球经济增长面临放缓压力，贸易保护主义抬头与地缘政治冲突加剧，导致传统贸易通道受阻、大宗商品价格波动。在此背景下，海洋养殖业凭借其资源节约、环境友好、高附加值等特性，成为破解“陆地资源瓶颈”与“粮食安全挑战”的关键突破口，而海洋牧场则是海洋养殖中颇具前景的发展方向。拖船作为海洋牧场建设与运输中不可或缺的工具，其性能直接影响整体效率。因此，提升拖船性能并改良拖曳运输方式，是优化海洋牧场建设与运营的关键环节。由于实物测试成本过于庞大，小比例模型仿真实验是探究其优化方案的有效方法。通过阐述拖船三维模型的建立以及实物化过程，开展模型制作与对比实验，可为行业工程设计提供有益思路。

Under the dual background of profound adjustments in the global economic landscape and the accelerated development of marine resources， marine aquaculture is becoming an important strategic field for countries to ensure food security and promote economic transformation. In 2025， global economic growth is facing slowdown pressure， with the rise of trade protectionism and the intensification of geopolitical conflicts， leading to the obstruction of traditional trade channels and increased volatility in commodity prices. Against this backdrop， marine aquaculture， with its resource-saving， environmentally friendly， and high-value-added characteristics， has become a key breakthrough to address the “land resource bottleneck” and “food security challenges”. Marine ranching is a promising concept in marine aquaculture. As an indispensable tool in the construction and transportation of marine ranches， tugboats naturally play a crucial role. Therefore， to enhance the efficiency of marine ranch construction and transportation， improving the performance of tugboats and optimizing the towing transportation method are naturally important considerations. Due to the prohibitively high cost of physical testing， small-scale model simulation experiments are an excellent method to explore optimization solutions. This paper elaborates on the establishment of a three-dimensional model of the tugboat and its physical realization process， and conducts comparative experiments with the fabricated model， providing a new perspective for industry engineering design.
