Abstract: The process of standardization, upsizing and specialization of inland river ships is constantly accelerating. When ships sail in the Three Gorges Reservoir area in wind, wave, and current environments, they often encounter problems such as severe swaying motion, speed reduction, unstable heading and difficult maneuvering. Therefore, the reliability of ship emergency mooring system design in shallow waters of the Three Gorges Reservoir area has become an urgent problem to be solved in the field of ship engineering. Taking the typical ship in the Three Gorges Reservoir area as the research object, a numerical model of the ship emergency mooring system was established by use of ANASYS-AQWA, which was based on the three-dimensional potential flow theory. The design of different cable layout schemes was optimized, and the amplitude of ship motion response and cable tension with different mooring schemes were compared and analyzed. The research shows that compared with the cable arrangement scheme of the 4-4 mooring system, the cable arrangement scheme of the 4-2-2 mooring system has more rationality and superiority in terms of balancing the tension of the mooring cable. The proposed research method can provide a scientific and reliable theoretical basis for the design of emergency mooring system scheme for ships in shallow waters of the Three Gorges Reservoir area.

摘要： 内河船舶标准化、大型化、专业化进程不断加快，三峡库区船舶在风、浪、流环境中航行时,往往会出现较剧烈的摇荡运动、降速、航向不稳定及操纵困难等问题。因此，三峡库区浅水域船舶应急系泊系统设计的可靠性成为船舶工程领域亟待解决的问题。以三峡库区典型船舶为研究对象，基于三维势流理论，运用 ANASYS-AQWA ，建立船舶应急系泊系统的数值模型，优化设计不同缆绳布置方案，对比分析不同系泊方案下船舶运动响应幅值及缆绳张力。研究表明：4-2-2系泊系统缆绳布置方案与4-4系泊系统缆绳布置方案相比而言，在均衡系泊缆张力方面更具有合理性、优越性。研究方法可为三峡库区浅水域船舶应急系泊系统方案的设计提供科学可靠的理论依据。
