摘要
本文分析风浪对VLCC船舶的影响,重点研究风浪中船舶受到的阻力情况以及风浪对船舶动力系统的影响,并给出VLCC船舶阻力随傅汝德数变化的曲线。分析船舶主机能效的优化方法,同时拟合出船舶主机功率和燃油消耗率之间的曲线关系。最后,构建出船舶分段航速的优化模型。本文对波浪中VLCC船舶的航行速度以及能效进行优化分析,这有利于VLCC船舶节能减排技术的进一步发展。
The influence of wind and waves on VLCC ships is analyzed.The resistance of ships in wind and waves and the influence of wind and waves on ship power system are mainly studied,and the curve of VLCC ship resistance changing with Froude number is given.The optimization method of marine main engine energy efficiency is analyzed,and the curve relationship between marine main engine power and fuel consumption rate is fitted.Finally,the optimization model of ship sectional speed is constructed.In this paper,the navigation speed and energy efficiency of VLCC ships in waves are optimized,which is conducive to the further development of energy conservation and emission reduction technologies for VLCC ships in China.
