Next, each function performed by the processing unit 23 of the ship operation management apparatus 20 will be described.
[Performance information estimation function]
The processing unit 23 of the ship operation management apparatus 20 estimates ship operation management information such as fuel consumption at a predetermined time interval (for example, every 20 minutes), for example, during a period from departure of the ship 10 to entry. In addition, a function of transmitting the estimated ship operation management information to the ship 10 is provided. Here, ship operation management information is information that is referred to when determining how to operate a ship.
The performance information estimation function will be described in detail below.
First, the characteristic creation unit 231 of the ship operation management apparatus 20 creates a speed characteristic and a fuel characteristic based on the operation data stored in the operation data storage unit 22.
For example, in creating speed characteristics, the characteristic creation unit 231 plots the operation data stored in the operation data storage unit 22 in a table in which the horizontal axis represents speed and the vertical axis represents output, and approximates this plot. A speed characteristic is created by connecting with a curve.
Similarly, the characteristic creation unit 231 plots the operation data stored in the operation data storage unit 22 in a table that represents the output on the horizontal axis and the fuel consumption rate on the vertical axis in creating the fuel characteristics. Fuel characteristics are created by connecting the plots with approximate curves.
FIG. 3 shows an example of speed characteristics, and FIG. 4 shows an example of fuel characteristics. In FIG. 3, the dotted line is a speed characteristic obtained based on operation data, and the solid line is an estimated characteristic, for example, a curve expressed based on the compensation performance of the ship, which is described in the main items of the ship functional specifications. It can be determined from the performance that is present. The curve indicating the speed characteristic is also called a horsepower curve.
In FIG. 4, the dotted line is the fuel characteristic obtained based on the operation data, and the solid line is the estimated characteristic, for example, a curve expressed based on the compensation performance of the ship, which is described in the main items of the ship functional specifications. It can be determined from the performance that is present.

Here, the characteristic creation unit 231 may use, for example, all the operation data stored in the operation data storage unit 22 in the above-described generation of the speed characteristic and the fuel characteristic, or the ship at that time Only the operation data corresponding to a predetermined condition related to the operation state may be extracted from the operation data storage unit 22 and the above characteristics may be obtained using only the extracted operation data.
For example, as shown in FIG. 5, the operation data that meets the conditions such as “June to August” for the date, “return” for the route, “2 m or less” for the wave height, and “5 m or less” for the wind speed are accumulated. It extracts from the part 22, and calculates | requires the said characteristic using the extracted operation data. As a result, it is possible to create accurate speed characteristics and fuel characteristics that match the current operating conditions.
Alternatively, the operation data for the past predetermined period (for example, two months) from the present may be extracted from the operation data storage unit 22, and the speed characteristics and the fuel characteristics may be created based on the extracted latest operation data. This makes it possible to create accurate speed characteristics and fuel characteristics that take into account aging degradation and the like.

In this way, when the speed characteristics (see FIG. 3) and the fuel characteristics (see FIG. 4) are created by the characteristics creation section 231, the estimation section 232 uses these characteristics to determine the fuel consumption and other factors of the ship. Estimate operation management information. For example, the speed at a predetermined output, the fuel consumption rate, the voyage time until entering the port, and the fuel consumption are estimated using the above characteristics.
For example, as shown in FIG. 6, when the reference output is “22304 kW”, the speed corresponding to this output “22304 kW” is acquired from the speed characteristics (dotted line in FIG. 3) created based on the operation data, The fuel consumption rate for the output “22304 kW” is acquired from the fuel characteristic (dotted line in FIG. 4) created based on the operation data.

  Subsequently, the distance to the port is obtained based on the current location of the ship, the position of the port of entry, the route, and the like included in the latest operation data received from the ship, and the speed (for example, “25. 7 kn "), the voyage time until the port entry (for example," 5.25h ") is calculated. Then, the fuel consumption amount is obtained by multiplying the voyage time (for example, “5.25h”) and the output “22304 kW” by the fuel consumption rate (for example, “178.6 g / kW / h”) acquired earlier. (For example, “20.9 ton”) is calculated.

Such processing is also performed for a preset reference output, which in this embodiment is “20272 kW”, “17244 kW”, “15240 kW”, and “10216 kW”. Estimate operation management information, that is, speed, fuel consumption rate, voyage time to port entry, and fuel consumption.
And if the operation management information of these ships with respect to each reference | standard output is estimated by the estimation part 232, the process part 23 will ship the estimated operation management information (refer FIG. 6) of these ships via the communication apparatus 21. 10 to send.

  Thereby, the ship operation management information is received by the satellite communication antenna 14 of the ship 10 via the Internet 50, the satellite communication antenna 40, and the communication satellite 30, and is input to the personal computer. And the operation management information of these ships input into the personal computer is displayed on the display with which a personal computer is equipped. Thereby, the operation management information of the ship at the present time is provided to the crew of the ship. The ship crew member controls the optimum ship operation, for example, the speed (speed) of the ship, with reference to the ship management information. As a result, it is possible to realize the operation of the ship that balances the scheduled operation and the energy saving operation.

  In the above-described embodiment, the ship operation management information is estimated based on the reference output. However, the reference information is not limited to the output, and is appropriately selected from the speed, the fuel consumption rate, and the voyage time before entering the port. Is possible. For example, when arrival time is given priority over anything, set the voyage time until entry to the port and estimate the output, speed, fuel consumption rate, fuel consumption, etc. based on this voyage time. Also good. In this way, it is possible to appropriately change the reference item depending on the priority item in the occasional voyage. Also, the reference value of the item to be used as a reference can be changed as appropriate, and can be specified from the ship 10, for example.

[Maintenance time determination function]
Next, the maintenance time determination function provided in the processing unit 23 of the ship operation management apparatus 20 will be described.
This function is performed, for example, at a preset time interval, for example, one month interval.
First, the characteristic creation unit 231 extracts the operation data when the sea condition is calm from the operation data for the past one month, and generates the speed characteristics described above based on the extracted operation data. And the difference between the speed (for example, the dotted line in FIG. 3) obtained from the speed characteristics based on the actual performance in the actual sea area and the speed in plain water (solid line in FIG. 3) estimated in advance by the tank test or theoretical calculation. To calculate a horsepower sea margin (hereinafter referred to as “sea margin”). Thereby, for example, a sea margin characteristic can be obtained with the horizontal axis representing speed and the vertical axis representing sea margin. Then, using this sea margin, the maintenance time determination unit 233 estimates a recommended maintenance time.

For example, when the sea margin calculated by the characteristic creation unit 231 does not satisfy a preset compensation standard, the maintenance time determination unit 233 determines that the recommended maintenance time is determined as the ship performance has deteriorated. After a predetermined period (for example, half a year later). Here, the compensation standard is, for example, performance compensated when purchasing a ship.
Then, when the recommended maintenance time is determined by the maintenance time determination unit 233, the processing unit 23 gives the recommended maintenance time, the sea margin characteristic, and the like to, for example, a maintenance company (not shown) that performs maintenance of the ship 10. Send to. As a result, information related to the maintenance is transmitted to the maintenance company via the Internet 50. The maintenance company can perform maintenance guidance and execution at an optimal time by sending maintenance guidance and the like to the operating company of the ship 10 based on the received information regarding maintenance.
Thus, since the sea margin is created based on the actual operation data and the recommended maintenance time is determined based on the actual sea margin, the maintenance can be performed at the optimum time according to the performance.

[About the performance evaluation function]
Next, the performance evaluation function with which the process part 23 of the ship operation management apparatus 20 is provided is demonstrated.
This function, for example, creates a sea margin characteristic for the influence of sea conditions based on operation data in a predetermined period (for example, one year), and evaluates the performance of the ship by referring to the sea margin characteristic.
First, the characteristic creation unit 231 of the processing unit 23 calculates the sea margin for the sea condition influence based on the operation data in the past year, and creates the sea margin characteristic for the sea condition influence based on the calculated sea margin data. The sea margin characteristics with respect to the sea state influence are, for example, a table in which the horizontal axis represents the wave height and the vertical axis represents the sea margin as shown in FIG. Here, as described above, the sea margin is, for example, the difference between the actual speed value in the actual sea area and the estimated speed value in plain water. When the sea margin characteristic for the sea state influence as shown in FIG. 7 is created by the characteristic creating unit 231, the processing unit 23 transmits the sea margin for the sea state effect to the ship 10 or the like via the communication device 31. . Thereby, the crew of the ship 10 can grasp | ascertain how much performance the ship 10 has, and it becomes possible to evaluate the actual performance of the ship by a sea state influence.

As described above, the operation management system according to the present embodiment has the following effects.
First, the speed characteristics and fuel characteristics of the ship 10 are created based on the operation data of the ship 10 acquired from the ship 10, and the operation management information of the ship 10 is estimated based on the speed characteristics and fuel characteristics. The estimated operation management information of the ship 10 is transmitted to the ship 10. Thereby, in the ship 10, it becomes possible to implement | achieve optimal ship operation based on the highly accurate ship operation management information estimated based on own operation data.

  Secondly, the operation data when the sea condition is calm is extracted from the operation data stored in the operation data storage unit 22, and the sea margin due to the aged deterioration is calculated based on the extracted operation data, Since the recommended maintenance time is determined using the sea margin resulting from the aging deterioration, the maintenance time can be determined at an optimum time.

  Thirdly, since the sea margin resulting from the sea-state effect is calculated based on the operation data stored in the operation data storage unit 22, it is possible to evaluate the actual performance of the ship due to the sea-state effect.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
First, the exchange of data performed between the ship 10 and the ship operation management device 20 is not limited to the above-described embodiment, and any technique that can realize mutual data communication may be used.
Secondly, the sea margin characteristics for the above-mentioned sea condition influence are not limited to those having the wave height on the horizontal axis. For example, a sea margin characteristic is created on the horizontal axis for each parameter relating to the sea condition, and based on this sea margin characteristic. The ship performance may be evaluated. Further, the method for creating the sea margin characteristics due to the above-described deterioration over time and the sea margin characteristics with respect to the influence of sea conditions is not limited to the above-described technique.
