A person who has responsible for ship’s safety, such as captain and Vessel Traffic Service Operator (VTSO), should make a decision to prevent the ship from colliding or other accident related on traffic situation. At this time, the positions of the own ship and the opponent ship are used for identification and prediction of the future situation, and the action is selected based on this information. Here, the person in charge predicts the position of itself and the opposing ship, and the calculated positions are called Dead Reckoning Position (DRP). In the existing DRP calculation, the position of the ship is predicted based on the current position, speed and course, so it cannot be applied in all navigation situations. For this reason, both the vessel and the VTS center utilize the navigation intentions of the two vessels related to the traffic situation for their own decision-making. In this study, we intend to predict the ship’s position based on the route extraction method proposed in the SVR seaway model. We predict the future speed, and propose a method of predicting the position applied to the SVR seaway model. For the verification of the proposed DRP calculation, a virtual path and ship’s trajectories which are similar to the actual navigation environment were constructed. As a result, comparison data between the existing DRP and proposed DRP are presented. And enhanced closest point of approach calculation results are presented for two approaching ships as a time series. We expect that the advanced DRP could be used for relevant tasks to ship’s mater and/or VTSO.
