5 is a diagram for describing a method of correcting weather forecast data according to the present embodiment.

First, since a ship operates for days or weeks, it is difficult to select a route using only weather forecast information. That is, since it is not easy to predict the weather forecast after a few days or weeks, the long-term weather forecast and observation data are accumulated (510) in order to increase the prediction accuracy of the weather forecast data.

Then, the accumulated weather forecast and observation data are modeled by period (eg, monthly, quarterly) as shown in FIG. 6, that is, the average value and the variability of the period are calculated (520). The error rate is learned (530). Specifically, the error ratio for the error between the forecast and the observation data for each period can be learned by using an artificial neural network.

FIG. 6A shows average wind speed and variability over time. FIG. Referring to Figure 6a, it can be seen that the wind speed is relatively low in early March and early September, the wind is relatively high in January and December. Therefore, when searching for a flight route for a vessel operating in winter, when the wind speed is predicted to be significantly lower than the average of the previous year, the forecast value can be used by upwardly correcting in consideration of the past average.

6B is a diagram illustrating average wave height (wave height) and variability for each period. Referring to FIG. 6B, the crest is low and the volatility is low in summer, but the crest is high and the volatility is large in winter. Therefore, when searching for a flight route for a vessel operating in winter, when the wave height is forecast to be significantly lower than the average of the previous year, the forecast value can be upwardly corrected in consideration of the past average.

FIG. 7 is a diagram for describing an operation of the fuel consumption estimator 160 of FIG. 2.

First, the corrected forecast data and performance information of the ship are collected as described with reference to FIGS. 5 and 6 (S710).

Here, δ R is an increase in ship resistance, δ R _wave is an increase in ship resistance according to _wave height and _wave direction, and δ R _wind is an increase in ship resistance according to _wind speed and wind direction.

Then, using the calculated vessel resistance increase amount and the following Equation 2 can be calculated the amount of ship lowering.

Here, δV is the speed change according to the increase in ship resistance, Ro is the basic resistance of the ship, δR is the increase in ship resistance.

Mathematical time 2 described above may be calculated using Equation 3 below using an approximation with measured data.

Then, the amount of horsepower increase for adjusting the speed of the ship can be calculated using the calculated speed decrease and the following equation (4).

Where δP is the horsepower increase and δV is the speed change as the ship resistance increases.

On the other hand, the above-described mathematical time 4 may be calculated using the following mathematical time 5 using an approximation with the measured data.

In addition, fuel consumption may be estimated using the calculated horsepower increase amount and Equation 6 below.

Here, δFOC is fuel consumption, SFOC is the fuel consumption of the ship according to the distance (conventional method), ship speed reduction amount can be calculated by using the following equation 4 to increase the horsepower for speed control.

In addition, the calculation is performed for each cell as shown in FIGS. 3 and 4, and is applied to each navigation route generated by the navigation route generation unit 140 so as to calculate the fuel consumption to be consumed for each navigation route. Can be estimated.

The provisioning system can be implemented.

Referring to FIG. 9, first, vessel navigation information is input (S910). Ship operation information may be input through the operator of the vessel or the administrator of the system.

In operation S920, a plurality of navigation routes are generated based on the received vessel navigation information.

Then, the weather information and the performance information of the vessel on the generated plurality of flight paths are acquired (S930). Specifically, at least one weather forecast data of wind speed, wind direction, wave height, and wave direction is received from the weather forecast center, and the received weather forecast data are corrected using the accumulated weather data, thereby correcting the corrected weather forecast data as weather information. It can be acquired. Meanwhile, the accumulated weather data includes past forecast data and past observed data on weather conditions such as wind speed, wind direction, wave height, and wave direction. The meteorological data and the fuel consumption information of the ship, which are currently observed on the ship's flight path, may be stored as accumulated data.

Then, fuel consumption for each of the plurality of flight routes is predicted based on the acquired weather information and performance information (S940). Specifically, the ship resistance increase amount is calculated based on the acquired weather information and the performance information, the ship speed increase amount is calculated based on the calculated ship resistance increase amount, and the horsepower increase amount for speed control is calculated based on the calculated ship speed decrease amount. The ship's fuel consumption can be calculated based on the calculated horsepower increase. The operation of each calculation step has been described above with reference to FIG. 7, and thus a detailed description thereof will be omitted.

In operation S950, an economic navigation route is selected from the plurality of navigation routes based on the estimated fuel consumption amount. Specifically, by comparing the predicted fuel consumption for each of the plurality of navigation routes, the navigation route having the least fuel consumption may be selected as the economic navigation route.

Then, the selected economic flight route is provided to the vessel (S960). Specifically, the selected economic flight route may be delivered to the vessel by wireless or wired communication, or the weather forecast information of the corresponding route may be transmitted together with the economic flight route.

Then, the weather information is updated on the selected economic flight route at a predetermined cycle (for example, a six-hour cycle) (S970), and whether the updated weather information is a predetermined range of the acquired weather information is determined (S980). . If the updated weather information is not within the preset range of the acquired weather information, the economic navigation route is searched again.

Therefore, the ship route providing method can search for a route through which the vessel can operate economically using weather information and provide the retrieved economic route to the vessel, thereby enabling economical operation of the vessel.
