摘　　要：燃油消耗费用在船舶营运费用中的占比巨大,采取有效措施以节约燃油费成为航运公司关注的问题。在对船舶减速航行的概念与原理进行理论阐述的基础上,从设计航速、经济航速、盈利航速三方面详细阐述了船舶的航速,通过对盈利航速和经济航速的计算分析,研究了船舶最佳运行航速,并结合实船降速航行节油实验进行计算分析比较。最后从主机减速运行的常见问题出发,剖析问题产生的原因,给出主机正常运转的建议与措施。Fuel consumption costs constitute a significant portion of operating expenses in the shipping industry.Implementing effective measures to save fuel costs has become a concern for shipping companies.Based on theoretical exposition of the concept and principles of ship deceleration,this paper elaborates on ship speed from three aspects:design speed,economic speed,and profit speed.By calculating and analyzing profit speed and economic speed,the optimal operating speed of ships is studied.Furthermore,combined with practical ship deceleration fuel-saving experiments,a comparative analysis is conducted.Finally,starting from common problems in main engine deceleration operation,the causes of these issues are analyzed,and recommendations and measures for normal main engine operation are provided.
