As a result, ship traffic has become more congested. Moreover, ship navigation is susceptible to weather and environmental conditions, and in some cases, it may become dangerous. Therefore, vessels are subjected to high-risk navigation conditions. To understand the latent risk of ship navigation, this study focused on the actual ship behavior. Thus, an analysis of ship behavior was carded out using historical ship navigation based on automatic identification system data. Consequently, a dynamic analysis of the speed and encounter situation was performed. One of the main results of this work was the understanding of the latent risk involved in ships navigating the Seto Inland Sea, which is one of the most congested routes in Japan. Moreover, the risk areas were obtained, and visualized using a geographical information system. The obtained results can be applied to ensure safe navigation and the development of a safe and efficient navigation model.展开更多

The traditional southern route through the Suez Canal between the East Asia and the Europe is referred as benchmark routte, general cargo ship and container ship are respectively selected as benchmark ships, which are analyzed and compared with Arctic NEP from fuel consumption, insurance, icebreaker fees and cost for SOLAS amendment, etc. The study reveals that Arctic NEP highly reduces general cargo ships＇ sailing time, container ships＇ fuel consumption, and contributes to shipping＇s sustainable development.展开更多
