一种实用的船舶动态最佳吃水差优化方法
|
摘要
为应对"能效运营指标(EEOI)自愿应用导则",减低能耗、节约成本,本文介绍了船舶动态最佳吃水差优化技术。通过理论分析及实船实海域试验,提出一种基于配载仪的最佳动态吃水差优化方法。利用该方法航海人员可以较简单地获取最佳纵倾值,可操作性强。比较试验数据与经验值,得出节能约1.1%。相比传统的CFD和船模试验法,该方法成本更小。船岸信息互联互通后,该方法可为大数据分析优化船舶操控性能提供一种新思路。
In order to cope with the "Energy Efficiency Operational Index(EEOI) Voluntary Application Guidelines"to reduce energy consumption and save costs, this paper introduces the trim optimization technology for ship dynamic. Through theoretical analysis and actual ship sea test, an optimal dynamic draft difference optimization method based on the loader computer is proposed. With this method, the seafarer can obtain the optimal trim value easily and has high operability. The test data is compared with the empirical value and the energy saving is about1.1%. Compared to traditional CFD and ship model tests, the cost is smaller. This method can provide a new idea for big data analysis and optimization of ship handling performance after ship-to-shore information interconnection.
