Abstract: A fuel oil information providing server device acquires a reference fuel oil price at bunkering locations on a sailing route specified by a voyage ID input to a terminal device by a user or at which a ship is able to call from the sailing route, and data indicating conditions for correcting the reference fuel oil price, and specifies a fuel oil price obtained by correcting the reference fuel oil price indicated by the acquired data in accordance with the conditions. Fuel oil information providing server device generates display instruction data for instructing that a specified fuel oil price be displayed as a list along with determination rules for a bunkering amount at one or more bunkering locations, and outputs the data to a terminal device that displays information to be used for formulating a bunkering plan.

Abstract: In connection with a voyage in which a ship visits several ports on a sailing route, when a user inputs a berthing period at each port on the sailing route on a screen in a computer for managing voyage information displayed by a terminal device, the terminal device specifies, with regard to each sectional sailing route between two neighboring ports on the sailing route, fuel consumption rate when the ship sails on the sectional sailing route based on a sailing speed determined by the input berthing periods and parameters of maritime weather conditions under which the ship sails on the sectional sailing route. The terminal device calculates fuel consumption required for sailing on each sectional sailing route and total fuel consumption required for sailing the entire sailing route using the specified fuel consumption rates.

Abstract: A ship assignment device acquires voyage schedule information including an operation time schedule and a sailing route of a voyage. The ship assignment device acquires, from a database, weather information related to the operation time schedule and the sailing route included in the schedule information. The ship assignment device acquires information regarding variations in fuel consumption rate from a database that stores the information for each of plural ships. On the basis of the acquired weather information and acquired information regarding each ship, the ship assignment device calculates the fuel consumption for when each ship sails on the sailing route included in the acquired voyage schedule information in accordance with the operation time schedule included in the voyage schedule information. On the basis of the calculation result, the ship assignment device outputs information identifying plural ships.

Abstract: The present invention provides an arrangement for providing a bunkering plan (bunkering ports and bunkering amounts at the bunkering ports) that reduces fuel costs in a voyage of a ship. According to one embodiment of the present invention, if a bunkering plan that brings about a lower fuel costs according to the current bunkering plan occurs in accordance with the change in fuel price at a specific port, for example, for a ship that is being sailed, a user such as a ship operation manager is notified of this event. Accordingly, a user is able to know easily which bunkering plan is suitable.

Abstract: Ship allocating device obtaining a shipping route data set indicating a shipping route of a routine transportation service, a ship number data set that indicates a number of ships used for the routine transportation service, and a schedule data set that indicates a schedule of assignments of ships for the routine transportation service. The ship allocating device obtains data sets indicating fluctuations in fuel consumption of ships. The ship allocating device calculates, for each of the candidate ships, fuel consumption required for the ship to traverse the shipping route indicated by the shipping route data set in accordance with a schedule indicated by the schedule data set based on the data set. The ship allocating device selects a number of ships equal to or greater than the number indicated by the ship number data set based on calculated fuel consumptions, and outputs data sets identifying selected ships.
