Description

  The present invention is intended for port entry that enables safe and efficient maneuvering from the nearest passing point to the pier on the route to reach the pier when a vessel regularly enters a specific port. It relates to a ship handling support system.

In the conventional voyage plan, the route to the destination port is set by various navigation methods such as the shortest detour navigation. In order to arrive at the destination port in the shortest time, taking into account the influence of weather and sea conditions, the passing points forming the route are sequentially set. However, in the conventional navigation system as described above, it is difficult to make a detailed ship maneuvering plan from when the ship arrives near the target port until the hull is laid on the pier in the port. Skill is needed.
