摘要
针对风帆助航船舶航行中受风力和水动力影响，出现较明显的船首偏转和船体漂移现象，对风帆及船体进行数学建模，分析不利于船舶航行保向的因素，为驾驶人员应急工况操舵提供安全参考。考虑到风帆的推力作用使船舶主机营运功率降低，对风帆助航船舶能效营运指数（EEOC）进行数学分析，得出风帆助航系统较大程度上有助于降低燃油消耗量、改善EEOI指数，从而达到降低排放，保护环境的目的。
In view of the influence of wind and hydrodynamic torces on the sail-assisted ships, there are obvious deflections of the bow and the drift of the hull. The mathematical modeling of the sail and hull is can＇ied out. The factors that are not conducive to the navigation of the ship are analyzed, so as to provide a saie reierence tor the helmsman in the emergency operation. Considering the effect of the ship sails thrust operating power down, the sail-assisted ships＂ efficiency operation index （EEOI） is analyzed. And the resuhs show that the sail system greatly helps to reduce tuel consumption and improve the EEOI index, so as to achieve the purpose of reducing emissions and protect the environment.
