摘要： A tank state estimating method of estimating a state in a tank at a predetermined point in time on a sailing course of an LNG carrier is provided. The LNG carrier carrying LNG stored in the tank as a cargo. The tank state estimating method includes: a first step of acquiring information related to specification of the tank; a second step of acquiring information related to a state in the tank at a start point of a target section on the course; a third step of acquiring information on a predictive value of liquid fluctuation of the LNG in the tank during the section, the predictive value being obtained on a basis of a weather forecasting value during the section and information on the weather forecasting value; and a fourth step of calculating the state in the tank at an end point of the section by thermal transfer calculation based on thermodynamics on a basis of the information acquired in the first to third steps in assuming that a heat input to the tank during the section is used for vaporization of the LNG in the tank.

摘要： A reference range identifying device acquires and records, at a predetermined time interval, a measuring result of a load and exhaust temperature of an engine. The device identifies, based on combinations of the load and exhaust temperature recorded at multiple points of time, for each load zone, for example a 95% confidence interval of a distribution of exhaust temperatures as a reference range. Subsequently, the device calculates an approximate curve for lower limits and upper limits of reference ranges identified for the load zones. The device identifies a range sandwiched by the calculated two approximate curves as a reference range that changes in accordance with a load. The device, upon detecting that a current load and exhaust temperature of the engine is not included in the reference range, notifies the detected fact to a user.

摘要： 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.

摘要： 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.

摘要： Reception unit receives data indicating water temperature of a body of water through which a vessel voyages, vessel speed, and a period for which those values are maintained. From storage unit, index value acquisition unit reads out a decrease amount of anti-fouling paint corresponding to the water temperature and vessel speed received by reception unit. Index value specification unit specifies a decrease amount of anti-fouling paint in the period by multiplying the length of time of the period received by reception unit by the decrease amount read out by index value acquisition unit. Remaining amount acquisition unit integrates the decrease amounts of the anti-fouling paint specified by index value specification unit at the time of coating with the anti-fouling paint and onward. Remaining amount specification unit specifies a current paint film thickness of the anti-fouling paint by subtracting the decrease amount of the anti-fouling paint integrated by remaining amount acquisition unit from the paint film thickness at the time of coating with the anti-fouling paint.

摘要： 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.
