Abstract: A point calculation device includes a point granting information acquisition unit configured to acquire a point granting start time and a point granting end time for use points relating to a vehicle; and a point calculation unit configured to calculate use points for a user of the vehicle according to a time difference between the acquired point granting start time and the acquired point granting end time.

Abstract: A point calculation device includes a shaking determination unit configured to acquire weather information or detection information of a vibration sensor mounted on a vehicle and determine a shaking of the vehicle according to the acquired information and a point calculation unit configured to calculate use points for the vehicle according to a determination of the shaking determination unit from a departure location to an arrival location of the vehicle.

Abstract: A point calculation device includes an actual movement route calculation unit configured to calculate an actual movement route of a vehicle from departure to arrival, and a point calculation unit configured to calculate use points according to a difference between the actual movement route and a preset movement route from a departure location to an arrival location.

Abstract: Provided is a ship propulsion system such that an increase in the size of a main engine can be minimized. The ship propulsion system is equipped with: main generators that supplies power to the interior of a ship; a power distribution unit that distributes the power of the main generators; a first electric motor that rotatably drives a first rotary shaft with the power input through the power distribution unit; a main propeller that rotates along with the first rotary shaft; a second electric motor that rotatably drives a second rotary shaft with the power input through the power distribution unit and a stern-side propeller that is disposed on the stern side of the main propeller and rotates along with the second rotary shaft.

Abstract: [Object] Conventionally, measures for securing stability of a ship when it is damaged are required. [Solution] The invention is characterized by having a remotely openable seawater inlet means provided to a lowermost watertight deck that forms a void space at the bottom of the ship. Thereby, when a side shell plate or the like of the ship is damaged and seawater enters the ship, the seawater that has entered the ship can be introduced into the void space by opening the seawater inlet means provided to the lowermost watertight deck, so that the void space, which usually provides a huge auxiliary buoyancy, can be made to function as a sort of a seawater ballast tank, whereby the ship's stability can be recovered.
