ABSTRACT
The Arctic is rapidly transforming into a navigable ocean because of global warming. Consequently, a large percentage of the sailing distance between Europe and Asia could be saved by alternatively sailing through the Arctic. However, taking Arctic routes is fraught with risks and additional costs due to sea ice. The major purpose of this study is to improve safety and fuel efficiency of Arctic ships, which is achieved by voyage optimization upon frequently updated meteorological, oceanographic and ice forecasting. The resistance model accounts for both ice thickness and ice concentration of unconsolidated Arctic sea ice in summer. Ice-induced risks defined in the Polar Operational Limit Assessment Risk Indexing System (POLARIS) are dealt as constraint. Other constraints such as avoidance of land and shallow water are also included. These functions are demonstrated by the two case study vessels sailing between Rotterdam and Shanghai via both the Arctic and the traditional routes.

一种通过北极在欧洲和亚洲之间航行的船舶的航海计划工具
摘要
由于全球变暖,北极正迅速转变为可航行的海洋。因此,通过交替穿越北极,可以节省欧洲和亚洲之间很大的航行距离。然而,由于海冰,选择北极航线充满了风险和额外费用。这项研究的主要目的是提高北极船舶的安全性和燃油效率,这是通过在经常更新气象,海洋和冰雪预报时优化航程来实现的。阻力模型考虑了夏季未固结北极海冰的冰厚度和冰浓度。在极地运行极限评估风险指数系统(POLARIS)中定义的冰源性风险作为约束条件。还包括其他条件,例如避免土地和浅水。
