当今的全球社会比以往任何时候都更加迫切需要发展一个安全、高效的海运系统。特别的推动力是原油价格的大幅上涨，这要求航运公司将其船舶的燃料消耗降至最低。此外，二氧化碳的排放受到了国际海事组织(IMO)发布的EEDI(能源效率设计指数)的限制。气象路线服务对航运公司来说变得更加重要。然而，这类服务用于天气预报和船速损失现象等目的的数值模式存在精度不足。此外，由于船舶运动、导航、发动机和天气参数的连续数据积累不足，天气路线模型的开发受到了阻碍。这项研究使用的数据是从一艘20000吨级散货船的全球航行中收集的，历时一年。建立了一些关于船舶运动、航速损失和波浪条件的新关系，并通过实验数据和船舶运动频率响应以及天气和海洋的数值模拟进行了验证。
The present global society has made the development of a safe and efficient maritime transportation system more imperative than ever before. Of particular impetus is the steep rise in the price of crude oil, which has required shipping companies to minimize the fuel consumption of their ships. Moreover, the emission of carbon dioxide has been restricted by the EEDI (Energy Efficiency Design Index) issued by the IMO (International Maritime Organization). Weather routing services have become more important to shipping companies. However, there are accuracy deficiencies in the numerical models employed by such services for purposes such as weather forecast and the ship speed loss phenomenon. Moreover, the development of weather routing models has been hampered by insufficient accumulation of continuous data on ship motions, and the navigation, engine, and weather parameters. The data used for this study was collected over one year from a 20,000 DWT class bulk carrier on worldwide voyages. Some new relationships regarding ship motions, speed loss, and wave conditions were developed, which were verified by experimental data and numerical simulations of the frequency response of the ship motion and of the weather and ocean.
