摘　　要：对国内设计建造的首艘无限航区13000DWT敞口多用途船进行敞口耐波性模型试验研究,包括模型参数确定、货舱上浪进水量测量、排水舷口有效性评估及模型试验结果分析,用以确定最小干舷;同时,对其后续设计提出改进建议。研究结果表明:设计一定高度的舱口围可减少大量的上浪进水;排水舷口的数量、尺寸和位置无法通过理论公式计算并确定,采用模型试验的方法比较有效。该研究可为同类型船舶的设计提供参考。This paper studies the seakeeping model test for the first 13 000 dwt hatchcoverless multi-purpose vessel designed and constructed by a Chinese institute for the unlimited navigation areas. The seakeeping model test is to determine the minimum freeboard, which includes the determination of model parameters, green water measurement in cargo tanks, assessment on the effectiveness of freeing ports and the analysis of the model test results, along with the suggestions for the improvement of subsequent designs. The result shows that the hatch coaming of certain height can significantly reduce green water onboard and the theoretical formulae cannot determine quantity, dimensions and positions of freeing ports, instead it is more effective to rely on the model test. This study provides references for the design of same ship types.
