When the predetermined time has elapsed (step A01: YES), the load data acquisition unit 21 stores the draft stored in association with the time within the most recent predetermined time (for example, one minute) from the storage unit 12. Data is read (step A02).

  Subsequently, the load data acquisition unit 21 specifies a representative value (for example, latest value, average value, median value, etc.) of the draft indicated by the read draft data (step A03). Subsequently, the load amount data acquisition means 21 subtracts the light load drainage amount of the ship 3 from the drainage amount (the current drainage amount of the ship 3) according to the representative value specified in step A03, so that the current load of the ship 3 is reached.

[Modification]
The above-described embodiments may be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below. These modifications may be combined as appropriate.

(1) In the above-described embodiment, the load amount data acquisition unit 21 calculates the load amount using the draft data, and generates load amount data indicating the calculated load amount. The method by which the load data acquisition unit 21 acquires the load data is not limited to this. For example, the user may input a load amount, and the load amount data acquisition unit 21 may acquire load amount data indicating the load amount input by the user.

(2) In the above-described embodiment, the load amount data acquisition unit 21 acquires load amount data indicating the loaded weight. The loaded weight is a weight including the weight of the ballast water and the weight of the fuel in addition to the weight of the cargo. The load amount indicated by the load amount data acquired by the load amount data acquisition means 21 is not limited to the weight including the weight of the cargo, the weight of the ballast water, and the weight of the fuel. For example, the load amount data acquisition unit 21 may acquire load amount data indicating the weight of the cargo.

  When the load data acquisition unit 21 acquires the load data indicating the weight of the cargo, the load data acquisition unit 21 displays the ballast water data indicating the weight of the ballast water loaded on the ship 3 in addition to the draft data. And the fuel amount data indicating the weight of the fuel loaded on the ship 3, and the weight of the ballast water indicated by the ballast water amount data and the fuel indicated by the fuel amount data from the drainage amount corresponding to the draft indicated by the draft data. You may acquire by generating the data which show the weight which subtracted the weight of this and the light load drainage amount of the ship 3 as loading amount data.

  In this modification, for example, the ship 3 includes a liquid level meter that measures the liquid level of the fuel stored in the fuel tank 36, and a liquid level meter that measures the liquid level of the ballast water stored in the ballast water tank 39. Is provided. The information processing apparatus 1 receives, from each of these liquid level gauges, liquid level data indicating the liquid level of fuel or ballast water, for example, every elapse of a predetermined time, and associates it with a reception time (indicating a measurement time). And stored in the storage unit 12.

  In step A02 of FIG. 6, the load data acquisition unit 21 reads out the liquid level data regarding each of the fuel and the ballast water in addition to the draft data. Further, in step A03 in FIG. 6, the load data acquisition unit 21 specifies the representative value of the liquid level for each of the fuel and the ballast water in addition to the specification of the representative value of the draft, and determines the liquid level of the specified fuel. Fuel amount data indicating the weight of the fuel corresponding to the representative value and ballast water amount data indicating the weight of the ballast water corresponding to the representative value of the specified ballast water level are generated.

  The load amount data acquisition unit 21 generates load amount data using the fuel amount data and the ballast water amount data generated as described above in step A03 of FIG.

  According to this modification, the fuel consumption amount used for transporting a unit weight of cargo for a unit distance is presented as the fuel consumption amount per unit load unit distance. As a result, the user can evaluate the fuel consumption from the viewpoint of cargo transportation efficiency.

  In this modification, the method by which the load data acquisition unit 21 acquires the load data indicating the weight of the cargo is not limited to the method described above. For example, the loading data acquisition means 21 includes draft data indicating the draft measured by the draft meter 42 when the ship 3 has finished unloading all cargo at the port, and draft when the cargo loading is completed. The loading data indicating the weight of the cargo may be generated using the draft data indicating the draft measured by the total 42. In this case, the load amount data acquisition means 21 generates load amount data indicating a value obtained by subtracting the drainage amount according to the draft at the completion of unloading from the drainage amount according to the draft at the completion of loading.

(3) In the above-described embodiment, the load data acquisition unit 21 acquires draft data indicating the draft of the ship 3 at each of a plurality of time points during navigation of the ship 3, and drafts for each of the plurality of time points. Data indicating the amount obtained by subtracting the light load drainage amount of the ship 3 from the drainage amount corresponding to the draft indicated by the data is generated as the load amount data. Therefore, the fuel consumption per unit load amount reflecting the change in the weight of the cargo accompanying the intake and discharge of the ballast water during the navigation of the ship 3 and the consumption of the fuel is presented.

  If the ballast water is not taken in or discharged during navigation, or if the amount of fuel consumed during navigation is negligibly small compared to the loaded weight, the load data acquisition means 21 will determine the weight of the loaded weight during navigation. A configuration may be employed in which the loading weight data acquisition means 21 uses the loading weight calculated using the draft data indicating the draft of the ship 3 when anchored at the port as the loading weight during navigation without performing the calculation.

(4) The output means 25 may output information on the fuel consumption per unit loading amount for each of the inter-port routes that the ship 3 has navigated. In this modification, the calculation means 24 specifies the period during which the ship 3 navigated each of the inter-port routes based on the port entry time and the port departure time for each port on the route of the ship 3 input by the user. Subsequently, the calculation means 24 calculates the fuel consumption per unit loading amount using the loading amount data, the navigation distance data, and the fuel consumption amount data corresponding to the specified period.
