基于实船测试结果的大型集装箱实船与船模相关分析研究

Research on Correlation Factors of Large Container Vessel Based on Sea Trial Results

以中远海运集团旗下一艘万箱级集装箱船为研究对象,开展船舶典型载况下船模-实船相关分析和航速预报技术的研究。基于ISO15016(2015)实船测试规程研制船舶实船性能测试平台,进行实船性能参数和风浪环境参数测试。开展了船舶EEDI载况下实船性能测试研究,根据实船测试结果和船模试验预报结果进行船模-实船相关分析。讨论典型载况下的功率相关因子、转速相关因子、阻力相关因子以及实船伴流修正相关因子,建立了实用的船模-实船航速预报相关因子取值方法。研究成果对于建立规范、实用的船模-实船航速预报方法具有指导意义和工程应用价值。

A container vessel with 10000 TEU owned by COSCO shipping group is taken as the object to research correlation factors and speed prediction method under typical loading conditions.Ship performance monitoring platform is developed based on ISO15016(2015)procedures to monitor ship performance and environmental parameters including EEDI loading condition and light ballast condition.Analysis of correlation factors used in ship model test-based performance prediction are carried out according to both ship performance monitoring results and model test results.Correlation factors including power factor,speed factor,resistance correlation allowance and wake correction factor are concluded under typical conditions.The research output is valuable and may provide a reference for establishing a standard and practical prediction method of seed and power of large container vessel.
