摘要

摘要在开始航次规划程序之前,应根据交通密度、限制深度、船舶报告系统的可用性、水文气象条件、高风险航区等各种因素,将未来航道上的整个航区划分为若干区段,以便概述保证船舶航行安全的措施。此外,这些因素对船舶航行中的航速也有直接的影响。另一方面,在同一段航线上,慢速蒸汽可以减少10-15%的燃油消耗。降低船速可以显著地减少其操作成本。然而,在选择经济上可行的航速时,应该记住,降低航速会导致每年航次的显著减少,从而减少年运费收入。因此,一个现实中重要而相关的问题是,必须找到船舶运行速度,使其在经济燃油消耗和船舶运行利润之间取得平衡。船舶航速模式优化的经典方法是基于燃油消耗对航速的三次依赖关系。因此,根据港口之间的距离、航程的持续时间和船舶到达港口的时间条件,在现代出版物中提出了基于额外收入或定期租船当量的速度模式优化方法。

Efficiency of Ship Operation in Transportation of Oversized and Heavy Cargo by Optimizing the Speed Mode Considering the Impact of Weather Conditions
Abstract Prior to commencing the voyage planning procedure, the entire navigation area on the forthcoming passage should be divided into several sections, depending on various factors, such as traffic density, restricted depths, availability of ship reporting systems, hydrometeorological conditions, high risk navigation areas in order to outline measures to ensure the safety of ship’s navigation. In addition, these factors have direct impact on the ship’s speed during the voyage. On the other hand, slow steaming can reduce fuel consumption on the same section of the route by 10-15%. Reducing the ship’s speed can significantly minimize its operating costs. However, when choosing economically feasible ship’s speed it should be kept in mind that reducing the speed can lead to a significant decrease in the number of voyages per year and, consequently, to the reduction of annual freight income. Therefore, a practically important and relevant problem is the necessity to find the speed of ship operation, which will provide a balance between economical fuel consumption and profits from ship operation. The classic approach to optimizing the speed mode of ships is based on the cubic dependence of fuel consumption on speed. Therefore, depending on the distance between ports, the duration of the voyage and the conditions for the time of arrival of the ship to the port, in the modern publications were proposed approaches to the optimization of the speed mode, based on the additional income or time-charter equivalent.
