最佳航线服务是根据船舶性能和载货特点,利用航行过程中的海洋水文气象资料,选择航时最短、消耗最低、损失最小和经济效益最高的最佳航线和最佳船速的一种航海术。所以,这种服务工作的实质就是优选航线与跟踪导航。 选择最佳航线是服务过程中所要解决的最困难和最重要的任务之一。由于影响船舶航行的海洋环境因素较多,它们在空间和时间方面的变化也很复杂,所以航线分析人员必须掌握大量的天气和海况资料,并能较准确地预报出短、中、长期的天气变化过程,首先要作出三天的天气预报和五天的天气展望。根据预报和展望推断当时出现的天气类型,结合所获得的
The best route service is based on the characteristics of ships and cargo, the use of ocean hydrological meteorological data during navigation, the selection of the shortest flight duration, the lowest consumption, the least loss and the highest economic benefit of the best route and the best speed of a voyage Surgery. Therefore, the essence of this service is to optimize the route and tracking navigation. Choosing the best route is one of the most difficult and important tasks to solve in the service process. Due to the large number of marine environments that affect the navigation of ships, and their complicated changes in space and time, route analysts must acquire a large amount of data on weather and sea conditions and can accurately predict the short, medium and long-term weather Change process, we must first make a three-day weather forecast and five-day weather forecast. According to forecasts and forecasts infer the type of weather that occurred at that time, combined with the obtained
