Abstract

The present invention provides a means for making it possible to easily determine whether the appropriate classification of fuel-oil is being used in light of emission regulations, for a ship that sails through an emissions-regulated sea zone. A fuel-oil that has been adjusted to a set viscosity is input to an engine 804. A temperature measuring device 17 measures the temperature of the fuel-oil input to the engine 804 (the temperature at the time of input). A server device 11 stores a table which indicates the relationship between the temperature of a fuel-oil adjusted to a set temperature (the temperature at the time of input) and the viscosity of the fuel-oil at a reference temperature. The server device 11 references the table to identify the viscosity of the fuel-oil at a reference temperature in accordance with the temperature measured by the temperature measuring device 17, and identifies the classification of the fuel-oil of the identified viscosity (for example, sulfur content).

Description

Apparatus, method, program, and recording medium for specifying type of fuel oil to be input to combustion apparatus for burning fuel oil

The present invention relates to a technique for specifying the type of fuel oil that is input to a combustion apparatus that burns fuel oil.

In order to protect the environment, the sea area (hereinafter referred to as “emission regulation sea area”, Emission Control Area, ECA) where regulations (hereinafter referred to as “emission control”) impose restrictions on the amount of environmentally hazardous substances that ships emit with combustion of fuel oil. There is. For example, fuel oil with a sulfur content higher than a specified value cannot be used in an emission-regulated sea area unless an exhaust gas purification device is used. Examples of a device for burning fuel oil in a ship (hereinafter referred to as “combustion device”) include, for example, a main engine, a generator, a boiler, and the like.

Generally, fuel oil with a low sulfur content is more expensive than fuel oil with a high sulfur content. Therefore, there are ships that do not comply with emission regulations to reduce fuel costs. In addition, the crew may not be aware that the ship has entered an emission-regulated area, and switching from fuel oil having a high sulfur content to fuel oil having a low sulfur content may not be performed.

In order to ensure that ships navigating in emission-restricted areas comply with emission regulations, unannounced vessel inspections are conducted by inspectors in emission-restricted areas. In ship inspection, it is checked whether fuel oil with a low environmental impact is being used in the emission-controlled sea area based on information such as logbooks and BDN (BunkerunkDelivery Note). BDN is a document issued from a fuel oil supplier, and BDN describes the sulfur content of fuel oil supplied to the ship.

加え In addition to confirmation based on the above logbook, submission of fuel oil samples may be required. In that case, it is necessary for the crew member to submit a sample of fuel oil that has been (or has been) input to the engine (an example of a combustion device) to the inspector in response to a request. The inspector measures the content of the sample submitted by the crew and determines whether or not emission regulations have been observed.

Patent Document 1 is an example of a document that discloses a technique for analyzing components contained in marine fuel oil. Patent Document 1 describes a mechanism for calculating CCAI (Calculated. Carbon Aromaticity Index) based on the density of fuel oil at 15 degrees Celsius and the kinematic viscosity of fuel oil at 50 degrees Celsius.

FIG. 1 is a diagram showing an overall configuration of a fuel oil management system 1 according to an embodiment of the present invention. Hereinafter, the configuration of the fuel oil management system 1 will be described.

The server device 11 is arranged on the ship 8 and manages data relating to the type of fuel oil used by the engine 804 (an example of a combustion device) of the ship 8. In the present embodiment, the type of fuel oil is identified by the sulfur content of the fuel oil. The server device 11 performs data communication with each of the server device 13 and the server device 15 disposed on land via the communication satellite 9. The server device 11 performs data communication with the terminal device 12 used by the crew of the ship 8 in accordance with a communication standard such as WiFi (Wireless Fidelity).

The terminal device 12 is a terminal device used by the crew of the ship 8. Although only one terminal device 12 is shown as an example in FIG. 1, the number of terminal devices 12 actually varies depending on the number of crew members and the like.

The server device 13 is a server device managed by the shipping company of the ship 8, for example. The server device 13 is disposed on land and performs data communication with the server device 11 disposed on the ship 8 via the communication satellite 9. Further, the server device 13 performs data communication with the terminal device 14 used by, for example, a staff member of the shipping company of the ship 8 via the Internet, for example.

The terminal device 14 is a terminal device used by, for example, a staff member of the shipping company of the ship 8. Although only one terminal device 14 is shown as an example in FIG. 1, the number of terminal devices 14 actually varies according to the number of shipping company staff and the like.

The server device 15 is, for example, a server device managed by an emission regulation supervisory organization. The server device 15 is disposed on land and performs data communication with the server device 11 disposed on the ship 8 via the communication satellite 9. Further, the server device 15 performs data communication with the terminal device 16 used by the staff of the supervisory organization, for example, via the Internet.

The terminal device 16 is a terminal device used by a supervisory organization staff. Although only one terminal device 16 is shown as an example in FIG. 1, the number of terminal devices 16 actually varies depending on the number of staff members of the supervisory organization.

Each of the plurality of tanks 801 is a tank for storing fuel oil. In many cases, each of the tanks 801 is a storage tank that receives the refueled fuel oil, a settling tank that separates moisture from the fuel oil by gravity, and a fuel oil that has undergone necessary processing before being charged into the engine. However, these configurations may be variously changed. The pump 802 normally transfers fuel oil from any one of the plurality of tanks 801 to the engine 804.

Viscosity adjusting device 803 is a device that adjusts the viscosity by heating or cooling the fuel oil supplied to engine 804. The viscosity adjusting device 803 includes a heating unit 8031 that heats the fuel oil to lower the viscosity when the viscosity of the fuel oil supplied from the tank 801 to the engine 804 is higher than a set viscosity (hereinafter referred to as “set viscosity”). , A cooling unit 8032 for cooling the fuel oil to increase the viscosity when the viscosity of the fuel oil is lower than the set viscosity, and a viscosity for measuring the viscosity of the fuel oil after the temperature is adjusted by the heating unit 8031 or the cooling unit 8032 A measurement unit 8033 and a control unit 8035 that controls operations of the heating unit 8031 and the cooling unit 8032 according to a comparison result between the viscosity measured by the viscosity measurement unit 8033 and the set viscosity are provided.

The engine 804 is a main engine of the ship 8 and generates propulsive force of the ship 8 by rotationally driving a propeller (not shown). The viscosity of the fuel oil charged into the engine 804 must be within the range specified by the manufacturer. Therefore, the fuel oil whose viscosity has been adjusted by the viscosity adjusting device 803 is input to the engine 804.

On the fuel oil path from the tank 801 to the engine 804, in addition to the components shown in FIG. 1, a filter for removing impurities from the fuel oil, and a buffer for temporarily storing the fuel oil before being introduced into the engine A tank, a valve for controlling the flow of fuel oil, and the like are arranged. In addition, a path for circulating the excess fuel oil from the engine 804 to the buffer tank is usually provided. However, since those configurations are obvious to those skilled in the art, they are omitted in FIG.

The temperature measuring device 17 measures the temperature of the fuel oil input to the engine 804 (hereinafter referred to as “temperature at the time of input”), and generates temperature data indicating the measurement result. The temperature data generated by the temperature measuring device 17 is transmitted to the server device 11 and the management unit 19 via, for example, a communication cable. The transmission of temperature data from the temperature measurement device 17 to the server device 11 and the management unit 19 may be performed wirelessly. Hereinafter, it is assumed that the temperature measuring device 17 is disposed in a pipe connecting the viscosity adjusting device 803 and the temperature measuring device 17. However, the temperature measuring device 17 may be arranged at any position as long as the temperature measuring device 17 can measure the temperature of the fuel oil supplied to the engine 804. For example, the temperature measuring device 17 may be disposed in the casing of the viscosity adjusting device 803 and measure the temperature of the fuel oil in the vicinity of the fuel oil outlet.

The antenna 18 is an antenna for receiving a navigation signal including time data necessary for specifying the position of the ship 8 from a plurality of satellites provided in the GNSS (Global Navigation Satellite System). The navigation signal received by the antenna 18 is input to the server device 11 and the management unit 19 via a cable, for example.

The management unit 19 stores the position data indicating the position of the ship 8 generated based on the navigation signal received by the antenna 18 and the temperature data received from the temperature measuring device 17 in association with each other in the housing. Is encrypted and transmitted to the server device 11. Hereinafter, a combination of temperature data and position data associated with each other is referred to as “temperature-on-position correspondence data”. The server device 11 transmits the on-time temperature / position correspondence data received from the management unit 19 to the server device 15.

FIG. 2 is a diagram showing the configuration of the management unit 19. The management unit 19 performs data communication between an integrated circuit 901 such as ASIC (Application Specific Integrated Circuit), a memory 902 that stores data generated by the integrated circuit 901, and an external device under the control of the integrated circuit 901. A communication IF 903 that is an IF (Interface) for performing the above is provided. Note that a configuration may be employed in which the management unit 19 includes a general-purpose processor instead of including the dedicated integrated circuit 901, and the processor performs processing according to a program stored in the memory 902.

FIG. 3 is a diagram showing a functional configuration of the management unit 19. The functional configuration of the management unit 19 will be described below. The temperature acquisition unit 191 receives temperature data from the temperature measurement device 17. The position acquisition unit 192 specifies the current position of the ship 8 based on the navigation signal input from the antenna 18 and generates position data indicating the specified position.

The association unit 193 associates the position data generated by the position acquisition unit 192 with the temperature data indicating the temperature of the fuel oil input to the engine 804 when the ship 8 is at the position indicated by the position data. The temperature / position correspondence data at the time of charging is generated. For example, the association unit 193 associates the latest position data with the temperature data at the time when the temperature data is received from the temperature measurement device 17, and generates the temperature / position correspondence data at the time of insertion.

Note that the way in which the association unit 193 associates position data and temperature data with each other is not limited to that described above. For example, the latest temperature data may be associated with the position data when the association unit 193 generates the position data. The association unit 193 generates or acquires time data indicating the current time, and associates the time data indicating the time when the temperature data or the position data is acquired from the temperature acquisition unit 191 and the position acquisition unit 192 with these data. Thus, a configuration in which temperature data and position data are associated with each other via time data may be employed.

The storage unit 194 sequentially stores the on-time temperature / position correspondence data generated by the association unit 193. For example, the encryption unit 195 encrypts data that has not been transmitted to the server device 11 among the input temperature / position correspondence data generated by the association unit 193 with a predetermined encryption key every time a predetermined time elapses. The encrypted input temperature / position correspondence data is transmitted to the server device 11 by the transmission means 196.

The encryption key used by the encryption means 195 is a public key or a common key unique to the supervisor. When the encryption unit 195 uses a public key, the secret key paired with the public key is managed by the server device 15 managed by the supervisory authority and kept secret to outsiders. When the encryption unit 195 uses a common key, the common key is managed by the server device 15 and is kept secret from outsiders. In any case, the on-time temperature / position correspondence data encrypted by the encryption means 195 can be decrypted only by the server device 15.

The transmission unit 196 transmits, for example, the on-time temperature / position correspondence data encrypted by the encryption unit 195 to the server device 11 every predetermined time.

The hardware configuration of the server device 11, the server device 13, and the server device 15 is, for example, a computer for a general server device. FIG. 4 is a diagram illustrating a basic configuration of the computer 10 employed as hardware of the server device 11, the server device 13, or the server device 15. The computer 10 includes a memory 101 that stores various data, a processor 102 that performs various data processing according to a program stored in the memory 101, and a communication IF 103 that performs data communication with other devices.

The hardware configuration of the terminal device 12, the terminal device 14, and the terminal device 16 is, for example, a computer for a general terminal device. FIG. 5 is a diagram illustrating a basic configuration of a computer 20 that is employed as hardware of the terminal device 12, the terminal device 14, or the terminal device 16. The computer 20 includes a memory 201 that stores various data, a processor 202 that performs various data processing according to a program stored in the memory 201, a communication IF 203 that performs data communication with other devices, and displays an image to the user. A display device 204 such as a liquid crystal display and an operation device 205 such as a keyboard for receiving user operations are provided.

Note that an external display device connected to the computer 20 may be used instead of or in addition to the display device 204 built in the computer 20. Further, instead of or in addition to the operation device 205 built in the computer 20, an external operation device connected to the computer 20 may be used. Further, a touch display or the like in which the display device 204 and the operation device 205 are integrated may be employed.

The server device 13 and the server device 15 use the data received from the server device 11 to generate a Web page that displays the type of fuel oil used by the ship 8 and distribute it to the terminal device 14 or the terminal device 16. Since the functional configurations of the server device 13 and the server device 15 are the same as the functional configuration of a general Web server device, description thereof is omitted.

The terminal device 12, the terminal device 14, and the terminal device 16 request the Web page that displays the type of fuel oil used by the ship 8 from the server device 11, the server device 13, or the server device 15, and the Web page to be distributed indicate. Since the functional configurations of the terminal device 12, the terminal device 14, and the terminal device 16 are the same as the functional configuration of a terminal device having a general Web browser function, description thereof is omitted.

FIG. 6 is a diagram illustrating a functional configuration of the server device 11. That is, the computer 10 that is the hardware of the server device 11 realizes a device including the components illustrated in FIG. 6 by performing processing according to the program for the server device 11. Note that the server device 11 may be configured as a so-called dedicated device in which the components illustrated in FIG. 6 are realized by hardware.

The functional configuration of the server device 11 will be described below. The temperature acquisition unit 111, the position acquisition unit 112, and the association unit 113 are the same components as the temperature acquisition unit 191, the position acquisition unit 192, and the association unit 193 included in the management unit 19. That is, the temperature acquisition unit 111 receives temperature data from the temperature measurement device 17. The position acquisition unit 112 specifies the current position of the ship 8 based on the navigation signal input from the antenna 18 and generates position data indicating the specified position. The association unit 113 associates the temperature data received by the temperature acquisition unit 111 and the position data generated by the position acquisition unit 112 with each other to generate temperature / position correspondence data at the time of charging.

The storage unit 114 stores data used by the fuel oil specifying unit 116 or the determination unit 119. Hereinafter, data stored in the storage unit 114 will be described. FIG. 7 is a diagram illustrating a data configuration of the BDN database stored in the storage unit 114. The BDN database is a database that stores a part of information described in the BDN of the fuel oil supplemented to the ship 8. The data stored in the BDN database is, for example, data input by operating the terminal device 12 when the crew of the ship 8 receives the BDN.

The BDN database is a collection of data records corresponding to each of the BDN, and data fields include [BDN number], [issuer name], [fuel supply start time], [fuel supply completion time], [fuel supply location], [Viscosity at 50 ° C.], [Sulfur content], [Supply oil amount], [Tank number]. Each data field stores data indicated by a field name. Note that [50 ° C. viscosity] stores data indicating the viscosity of the fuel oil at the reference temperature. The reference temperature is 50 degrees Celsius for liquid oil and 40 degrees Celsius for gas oil. Since most of the fuel oil used in ships is liquid oil, in this embodiment, for convenience, the viscosity of the fuel oil at the reference temperature is referred to as “50 ° C. viscosity”. The unit of data stored in [50 ° C. viscosity] is, for example, “cSt”. The unit of data stored in [sulfur content] is, for example, “mass%”. In [Tank No.], a number for identifying the tank 801 to be refueled is stored.

FIG. 8 is a diagram exemplifying a data configuration of a charging temperature / 50 ° C. viscosity relation database stored in the storage unit 114. The charging temperature / 50 ° C. viscosity relational database is a table corresponding to each of various set viscosities, such as 10cSt, 11cSt, 12cSt,... (Hereinafter referred to as “charging temperature / 50 ° C. viscosity relation table”). ) Is included. FIG. 8 shows, as an example, a charging temperature / 50 ° C. viscosity relationship table corresponding to a set viscosity of 15 cSt.

The injection temperature / 50 ° C viscosity relationship table shows the 50 ° C viscosity (viscosity at the reference temperature of the fuel oil) and the temperature at which the fuel oil having the 50 ° C viscosity is adjusted to the set viscosity and then input to the engine. It is a collection of data in which (temperature at charging) is associated. That is, the charging temperature / 50 ° C. viscosity relationship table includes [charging temperature] and [50 ° C. viscosity] as data fields. For example, the data illustrated in the first row of the charging temperature / 50 ° C. viscosity relationship table shown in FIG. 8 indicates that when the set viscosity is 15 cSt, fuel oil having a charging temperature of 123 degrees Celsius is input to the engine. In this case, the fuel oil has a 50 ° C. viscosity of 250 cSt.

8 is the data generated from the relationship between the temperature and viscosity of various types of fuel oil illustrated in the graph of FIG. The graph shown in FIG. 9 is as follows.

Graph G1: A graph showing the relationship between the temperature and the viscosity of fuel oil A (HFO (Heavy Fuel Oil) 500) having a viscosity of 247.9 cSt at 50 ° C.
Graph G2: A graph showing the relationship between the temperature and viscosity of fuel oil B (HFO (Heavy Fuel Oil) 180) having a viscosity of 105.0 cSt at 50 ° C.
Graph G3: A graph showing the relationship between the temperature and the viscosity of fuel oil C (LSFO (Low Sulfur Fuel Oil)) having a 50 ° C. viscosity of 55.4 cSt.
Graph G4: A graph showing the relationship between the temperature and the viscosity of fuel oil D (MGO (Marine Gas Oil)) having a viscosity at 50 ° C. of 4.0 cSt.

For example, when the set viscosity is 15 cSt, the graph G1 indicates that the set viscosity is obtained when the fuel oil A (50 ° C. viscosity is 247.9 cSt) is 122.5 degrees Celsius. Similarly, graph G2 indicates that the set viscosity is obtained when fuel oil B (50 ° C. viscosity is 105.0 cSt) is 102.5 degrees Celsius. Graph G3 shows that the set viscosity is obtained when fuel oil C (50 ° C. viscosity is 55.4 cSt) is 88.5 degrees Celsius. Graph G4 shows that the set viscosity is obtained when fuel oil D (50 ° C. viscosity is 4.0 cSt) is 2.0 degrees Celsius.

From the above, when the set viscosity is 15 cSt, the following is specified.
If the temperature of the fuel oil adjusted to the set viscosity (temperature at the time of charging) is 122.5 degrees Celsius, the 50 ° C. viscosity of the fuel oil is 247.9 cSt.
If the temperature of the fuel oil adjusted to the set viscosity (temperature at the time of charging) is 102.5 degrees Celsius, the 50 ° C. viscosity of the fuel oil is 105.0 cSt.
If the temperature of the fuel oil adjusted to the set viscosity (temperature at the time of charging) is 88.5 degrees Celsius, the 50 ° C. viscosity of the fuel oil is 55.4 cSt.
If the temperature of the fuel oil adjusted to the set viscosity (temperature at the time of charging) is 2.0 degrees Celsius, the 50 ° C. viscosity of the fuel oil is 4.0 cSt.

FIG. 10 is a scatter diagram in which the relationship between the temperature at the time of charging and the viscosity at 50 ° C. (when the set viscosity is 15 cSt) is plotted, and an approximate curve (a logarithmic approximate curve in FIG. Is a graph). The data of the charging temperature / 50 ° C. viscosity relationship table shown in FIG. 8 is data generated according to the approximate expression of the approximate curve of FIG. 10, for example.

The explanation of the data stored in the storage unit 114 will be continued. FIG. 11 is a diagram illustrating a data configuration of an emission regulation database stored in the storage unit 114. The emission control database is a collection of data records corresponding to the sea area where emission control is performed, and includes [sea area] and [fuel oil restriction condition] as data fields. [Sea area] stores sea area data indicating, for example, a vector format of the sea area where emission control is performed. [Fuel oil restriction conditions] stores data indicating restriction conditions imposed by the emission regulations on the components of fuel oil in the sea area indicated by [Sea area]. The data stored in [Fuel oil restriction conditions] indicates the conditions related to the components of the fuel oil that are permitted to be used, such as “Fuel oil with a sulfur content of 1.5 mass% or less can be used”. Alternatively, a condition relating to a component of the fuel oil whose use is prohibited, such as “a fuel oil whose sulfur content exceeds 1.5 mass% cannot be used” may be indicated. Hereinafter, data stored in [Sea area] and [Fuel oil restriction condition] of each record of the emission regulation database is referred to as “fuel oil restriction condition data”. The data stored in the emission regulation database is, for example, data created by an emission regulation supervisory authority and provided to shipping companies.

FIG. 12 is a diagram illustrating a data configuration of the route data stored in the storage unit 114. The route data is data indicating the route on which the ship 8 navigates. For example, the route data is a collection of data arranged in the order of passing data indicating the passing points by latitude and longitude. The route data is, for example, data created by a staff member of the shipping company of the ship 8.

FIG. 13 is a diagram exemplifying the data configuration of the on-time temperature / position correspondence database stored in the storage unit 114. The on-time temperature / position correspondence database is a database that sequentially stores on-time temperature / position correspondence data generated by the association means 113 in time series. The input temperature / position correspondence database illustrated in FIG. 13 is a collection of data records corresponding to each of the temperature data acquired by the temperature acquisition unit 111, and includes [time], [input temperature], [ Position], [Sulfur content], [Appropriate / Inappropriate].

[Time] stores data indicating the time at which the temperature data was acquired by the temperature acquisition unit 111. [Temperature at the time of input] stores temperature data. [Position] stores the latest position data acquired by the position acquisition unit 112 when the temperature data is acquired. [Sulfur content] stores data indicating the sulfur content of the fuel oil specified based on the temperature data. [Appropriate / Inappropriate] stores data indicating whether or not the sulfur content of the fuel oil is appropriate in light of emission regulations.

The above is the description of the data stored in the storage unit 114. Returning to FIG. 6, the description of the functional configuration of the server device 11 is continued. The viscosity acquisition unit 115 refers to the BDN database (FIG. 7) stored in the storage unit 114, and viscosity data ([50 ° C. viscosity] indicating the 50 ° C. viscosity of fuel oil that may be input to the engine 804. Data stored in).

Specifically, the viscosity acquisition unit 115 responds to a request from the fuel oil specifying unit 116, and the latest data record (for example, [the refueling completion time] data is the latest for each of the plurality of tanks 801) from the BDN database. The data stored in [50 ° C. viscosity] of the retrieved data record and the data stored in [sulfur content] are read out. These data read by the viscosity acquisition means 115 indicate the 50 ° C. viscosity and sulfur content of the fuel oil stored in each of the tanks 801 at that time. The viscosity acquisition unit 115 delivers the data read from the BDN database to the fuel oil specifying unit 116.

The fuel oil specifying means 116 specifies the type of fuel oil introduced into the engine 804 based on the temperature data acquired by the temperature acquisition means 111. Specifically, when new association temperature / position correspondence data is generated by the association unit 113, the fuel oil identification unit 116 refers to the introduction temperature / 50 ° C. viscosity relation database (FIG. 8), and determines the temperature. The 50 ° C. viscosity is determined according to the charging temperature indicated by the data. Normally, there is a range in the viscosity of the fuel that can be charged into the engine (viscosity at the time of charging). Therefore, a value having a width such as “12 to 18 cSt” is given as the set viscosity. Therefore, when the fuel oil specifying means 116 follows this example, the table corresponding to each of the set viscosities “12 cSt” and “18 cSt” among the tables included in the charging temperature / 50 ° C. viscosity relation database, The range of 50 ° C. viscosity corresponding to the charging temperature indicated by the temperature data is specified. Further, the fuel oil specifying unit 116 receives data indicating the 50 ° C. viscosity and the sulfur content of the fuel oil currently stored in each of the tanks 801 from the viscosity obtaining unit 115.

The fuel oil specifying means 116 specifies the tank 801 that stores fuel oil having a viscosity of 50 ° C. within the range specified by the temperature data, and specifies the sulfur content of the fuel oil stored in the specified tank 801. The sulfur content specified in this way indicates the type of fuel oil that has been input to the engine 804 at that time. Data indicating the sulfur content specified by the fuel oil specifying means 116 is stored in [Sulfur content] of the corresponding data record in the temperature / position correspondence database (FIG. 13).

FIG. 14 is a graph for explaining a method by which the fuel oil specifying means 116 specifies the type of fuel oil. The vertical axis of the graph in FIG. 14 indicates the on-time temperature indicated by the temperature data acquired by the temperature acquisition unit 111, and the horizontal axis indicates time. Note that the position of the ship 8 corresponding to each time on the horizontal axis of the graph of FIG. 14 is specified by referring to the on-time temperature / position correspondence database (FIG. 13).

14 is the fuel oil stored in the tank 801. The fuel oils A to D illustrated in the graph of FIG. Fuel oil A has a 50 ° C. viscosity of 247.9 cSt, and the temperature of the fuel oil A that is input to the engine 804 (temperature at the time of input) is approximately 116 degrees Celsius in light of the input temperature / 50 ° C. viscosity relationship database (FIG. 8). Degrees to 133 degrees. Further, the fuel oil B has a viscosity of 105.0 cSt at 50 ° C., and the temperature of the fuel oil B introduced into the engine 804 (temperature at the time of introduction) is approximately 98 to 113 degrees Celsius. Further, the fuel oil C has a viscosity of 55.4 cSt at 50 ° C., and the temperature of the fuel oil C charged into the engine 804 (temperature at the time of charging) is approximately 81 to 96 degrees Celsius. Further, the fuel oil D has a viscosity at 50 ° C. of 4.0 cSt, and the temperature of the fuel oil D introduced into the engine 804 (temperature at the time of introduction) is approximately 9 degrees Celsius or less.

Further, the sulfur contents of the fuel oils A to D are, for example, 2.97% by mass, 1.02% by mass, 0.96% by mass, and 0.003% by mass, respectively.

When the data illustrated in the graph of FIG. 14 is obtained, the fuel oil specifying unit 116 may change from fuel oil A (sulfur content: 2.97 mass%) to fuel oil B (sulfur content: 1 on May 28). .02% by mass), and switching from fuel oil B to fuel oil D (sulfur content: 0.003% by mass) on June 9 is specified.

When fuel oils having different sulfur contents with different viscosities are accommodated in the plurality of tanks 801, the fuel oil specifying means 116 is a candidate fuel oil that is using two or more types (sulfur contents) of fuel oil. It may be specified as In this case, the fuel oil specifying means 116 cannot specify the type of fuel oil (sulfur content) as one, but can specify the range of the type of fuel oil (range of sulfur content).

The fuel oil restriction condition obtaining unit 117 obtains fuel oil regulation data corresponding to the sea area including the position designated by the judging unit 119 from the emission regulation database (FIG. 11), and delivers it to the judging unit 119.

The route acquisition unit 118 reads the route data (FIG. 12) stored in the storage unit 114 and delivers it to the determination unit 119.

Determination means 119 determines whether or not the type (sulfur content) of the fuel oil currently used by the ship 8 is appropriate in light of the fuel oil restriction conditions related to the current position of the ship 8. The case where the fuel oil being used by the ship 8 is inappropriate means that the type of fuel oil being used does not satisfy the fuel oil restriction condition, or the type of fuel oil being used is the fuel oil. This is a case where the quality is unnecessarily high in light of the limiting conditions.

Specifically, the determination means 119 identifies the current position of the ship 8 with reference to the temperature / position correspondence database (FIG. 13) at the time of entry, and corresponds to the current position of the ship 8 with reference to the discharge regulation database (FIG. 11). Identify fuel oil restriction conditions. Further, the determination unit 119 determines whether or not the sulfur content of the fuel oil currently supplied to the engine 804 is appropriate in view of the specified fuel oil restriction condition with reference to the input temperature / position correspondence database. . Data indicating the result of determination by the determination means 119 is stored in [Appropriate / Inappropriate] of the corresponding data record in the on-time temperature / position correspondence database (FIG. 13).

Also, the determination means 119 determines whether or not the type of fuel oil currently in use is improper in the near future when the ship 8 continues to follow the route.

Specifically, the determination unit 119 determines whether the ship 8 is based on the current position of the ship 8 based on the route data (FIG. 12) and the latest data record indicated by the latest temperature / position correspondence database (FIG. 13). The sea area that passes while moving by a predetermined distance (hereinafter referred to as “the sea area that will pass soon”) is specified. Subsequently, the determination unit 119 specifies the fuel oil restriction condition with reference to the emission regulation database (FIG. 11) regarding the sea area that is about to pass. Further, the determination means 119 determines the fuel oil limit for the sea area where the sulfur content (the sulfur content of the fuel oil currently input to the engine 804) indicated by the latest data record of the input temperature / position correspondence database passes. Judge whether it is appropriate in light of the conditions.

Encrypted data acquisition means 120 receives the encrypted temperature / position correspondence data sent from the management unit 19.

When the determination unit 119 makes a new determination, the transmission unit 121 transmits determination result data indicating the result to the terminal device 12. Further, the transmission unit 121 transmits, for example, a copy of the on-time temperature / position correspondence database (FIG. 13) (for example, a difference from the transmitted data) to the server device 13 and the server device 15 every elapse of a predetermined time. . Further, the transmission unit 121 stores, for example, a copy of the encrypted on-time temperature / position correspondence data received by the encrypted data acquisition unit 120 (for example, a difference from the transmitted data) every time a predetermined time elapses. Transmit to device 15.

The above is the description of the functional configuration of the server device 11. Next, the operation of the fuel oil management system 1 will be described. For example, the management unit 19 and the server device 11 receive a navigation signal from the antenna 18 every time a predetermined time elapses, and receive temperature data from the temperature measurement device 17 every time a predetermined time elapses, for example.

Each time the management unit 19 receives a navigation signal from the antenna 18, it generates position data indicating the current position of the ship 8 based on the received navigation signal. Each time the management unit 19 receives temperature data from the temperature measuring device 17, the management unit 19 associates the received temperature data with the latest position data separately generated to generate the input temperature / position correspondence data, and then encrypts the data. To do. The management unit 19 transmits the encrypted input temperature / position correspondence data to the server device 11.

Each time the server apparatus 11 receives a navigation signal from the antenna 18, the server apparatus 11 generates position data indicating the current position of the ship 8 based on the received navigation signal. Each time the management unit 19 receives temperature data from the temperature measurement device 17, the management unit 19 stores the received temperature data and the latest position data separately generated in association with each other.

When the server device 11 newly stores the combination of the temperature data and the position data, the server device 11 specifies the sulfur content of the fuel oil currently used by the ship 8 based on the temperature data. Subsequently, the server device 11 illuminates the fuel oil restriction condition regarding each of the sea area including the current position of the ship 8 indicated by the position data and the sea area where the ship 8 passes shortly, and the sulfur content of the fuel oil currently used is determined. It is determined whether it is appropriate. The server device 11 transmits determination result data indicating the determination result to the terminal device 12.

When receiving the determination result data from the server device 11, the terminal device 12 displays, for example, the following message according to the determination result indicated by the determination result data.

First, if the type of fuel oil currently used by the ship 8 is not appropriate in light of the fuel oil restriction conditions of the marine area where the ship 8 is currently navigating, the terminal device 12 will give a “warning! "Please change the fuel oil as soon as possible." Is displayed.

In addition, if the type of fuel oil currently used by the ship 8 is not appropriate in light of the fuel oil restriction conditions of the sea area where the ship 8 will pass soon, the terminal device 12 will indicate “Warning! The message “You are approaching. Please switch the fuel oil.” Is displayed.

The crew of the ship 8 switches the fuel oil according to the message displayed on the terminal device 12.

In addition to transmitting the determination result data to the terminal device 12, the server device 11 inputs, for example, a copy of the on-time temperature / position correspondence database (FIG. 13) to the server device 13 and the server device 15 every time a predetermined time elapses. A duplicate of the temperature / position correspondence database and encrypted time / position correspondence data is transmitted.

The server device 13 determines whether or not the type of fuel oil currently used by the vessel 8 is appropriate for the staff of the shipping company of the vessel 8 based on the duplicate of the temperature / position correspondence database at the time of input received from the server device 11. Notice. Specifically, when a shipping company staff operates the terminal device 14 to access the server device 13, the server device 13 is stored in [Appropriate / Inappropriate] in the latest data record of the temperature / position correspondence database at the time of entry. Display instruction data for instructing display of the contents of the data being generated is generated and transmitted to the terminal device 14.

If the fuel oil currently used by the ship 8 is appropriate according to the display instruction data received from the server device 13, for example, the terminal device 14 displays a message “The fuel oil being used is appropriate”. On the other hand, if the fuel oil currently used by the ship 8 is not appropriate, for example, a message “The fuel oil being used is inappropriate” is displayed. In response to a message that the fuel oil being used is inappropriate, the shipping company staff contacts the crew of the ship 8 by telephone or the like, for example, and prompts the fuel oil to be switched.

In addition, the server device 13 displays a display instruction for displaying whether or not the type of fuel oil used in the past by the ship 8 is appropriate based on the data stored in the temperature / position correspondence database at the time of input to the terminal device 14. Data is generated and transmitted to the terminal device 14. For example, the server device 13 generates display instruction data for displaying the route on which the ship 8 has navigated in the past according to the appropriate / inappropriateness of the fuel oil used and illustrated on the map, and transmits the display instruction data to the terminal device 14. . As a result, the staff of the shipping company can intuitively know in which navigation section the ship 8 was using an inappropriate type of fuel oil by looking at the map displayed on the terminal device 14.

The server device 15 notifies the supervisory engineer whether or not the type of fuel oil used by the ship 8 in the past is appropriate based on the duplicate of the temperature / position correspondence database at the time of input received from the server device 11. Specifically, when a staff member of the supervisory organization operates the terminal device 16 to access the server device 15, the server device 15 selects the route on which the ship 8 has navigated in the past depending on whether the fuel oil used is appropriate or inappropriate. Display instruction data to be color-coded and displayed on the map is generated and transmitted to the terminal device 16. As a result, the staff of the supervisory organization can intuitively know which navigation section the ship 8 was using an inappropriate type of fuel oil by looking at the map displayed on the terminal device 16.

If the supervisor's staff learns that the wrong type of fuel oil has been used by the ship 8, it will contact the shipowner of the ship 8, for example, and perform a prescribed procedure such as imposing a penalty. At that time, the supervisory institution can use, as evidence, data obtained by decrypting the encrypted input temperature / position correspondence data received by the server device 15 from the server device 11 with the secret key of the supervisory institution.

As described above, according to the fuel oil management system 1, whether or not the type of fuel oil used in the ship 8 is appropriate in light of the fuel oil restriction condition is determined based on the temperature of the fuel oil input to the engine 804 ( (Temperature at the time of charging) and the position of the ship 8. Therefore, it is not necessary to collect fuel oil samples or analyze the contained components, and it is easy and low-cost to determine whether the ship 8 complies with the emission regulations.

[Modification]
The above-described embodiments can be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below. The following two or more modifications may be combined.

(1) In specifying the type of fuel oil used by the ship 8 in the past, the server device 11 may use data related to fuel oil switching in addition to temperature data. For example, when the crew of the ship 8 performs switching of the tank 801, the switching timing and the tank number for identifying the tank 801 before and after the switching are input to the terminal device 12. Upon receiving these data input to the terminal device 12, the server device 11 refers to the BDN database (FIG. 7) and identifies the type of fuel oil currently in use. And the server apparatus 11 collates the classification of the fuel oil specified based on the tank number received from the terminal device 12, and the classification of the fuel oil specified based on temperature data, and confirms the correctness. According to this modification, for example, when two or more types of fuel oil are specified as candidates based on temperature data, it is possible to specify which of these candidates is the type of fuel oil being used.

(2) In the above-described embodiment, the server device 11 and the management unit 19 individually receive the navigation signal from the antenna 18 and specify the position of the ship 8. Instead, a configuration may be employed in which position data indicating the position specified by either one of the server device 11 and the management unit 19 is transmitted to the other. In this case, the device on the side receiving the position data does not need to have a function of specifying the position itself.

(3) In the above-described embodiment, each of the server device 11 and the management unit 19 receives temperature data directly from the temperature measurement device 17. Instead, a configuration in which one of the server device 11 and the management unit 19 receives temperature data from the temperature measurement device 17 and transfers it to the other may be employed.

(4) In the above-described embodiment, the server device 11 specifies and specifies the 50 ° C. viscosity according to the charging temperature indicated by the temperature data with reference to the charging temperature / 50 ° C. viscosity relation table (FIG. 8). A fuel oil having a viscosity of 50 ° C. is specified as the used fuel oil. It replaces with this and the structure which specifies the classification of the fuel oil according to the temperature at the time of injection which the temperature data shows without the server apparatus 11 specifying the 50 degreeC viscosity of fuel oil may be employ | adopted. For example, for each of the fuel oils stored in the tank 801, a temperature for setting the viscosity (temperature at the time of charging) is specified in advance and stored in the server device 11. FIG. 15 is a diagram exemplifying a data structure of a charging temperature / tank relationship table used in place of the charging temperature / 50 ° C. viscosity relationship table (FIG. 8) in this modification. In FIG. 15, there is a range in the temperature at the time of charging because there is a range in the viscosity of fuel that can be input into the engine (viscosity at the time of charging). The server device 11 refers to the on-temperature / tank relationship table and identifies the tank number corresponding to the on-temperature shown in the temperature data. Subsequently, the server device 11 refers to the BDN database (FIG. 7) and identifies the type of fuel oil (such as sulfur content) according to the identified tank number.

(5) Communication path when the management unit 19 receives a navigation signal from the antenna 18 in order to improve the reliability of the temperature / position correspondence data at the time of transmission transmitted from the management unit 19 to the server device 15 via the server device 11 Then, measures may be taken to make it difficult to modify the communication path when the management unit 19 receives temperature data from the temperature measurement device 17.

For example, the communication units provided in the management unit 19, the antenna 18, and the temperature measurement device 17 and the communication cables (in the case of wired communication) connected to the communication unit are not replaced illegally. A key may be provided to prevent opening and closing of personnel other than those of the supervisory authority. Moreover, you may provide the seal | sticker which is damaged when the housing | casing of those apparatuses is opened. In this case, since the seal is damaged when the casing is opened improperly, the supervisory body confirms that the seal is not damaged, so that the temperature / position at the time of input transmitted from the management unit 19 to the server device 15 is confirmed. The reliability of the corresponding data can be confirmed.

(6) In the embodiment described above, the type of fuel oil is distinguished by the sulfur content. The type of fuel oil is not limited to the sulfur content, but may be distinguished based on any of the contents of other substances, combinations thereof, and other physical properties.

(7) In the description of the above-described embodiment, the staff of the supervisory organization determines the type of fuel oil used in the ship 8 based on the data received by the terminal device 16 from the management unit 19 via the server device 11 and the server device 15. To confirm whether it is appropriate in light of the fuel oil restriction conditions. Alternatively or in addition, the staff of the supervisory organization opens the housing of the management unit 19 by using a key or the like when the ship 8 is inspected, and the data stored in the management unit 19 is transferred to the terminal device 16 or the like. You may read out and use.

(8) In the embodiment described above, the fuel oil management system 1 identifies the type of fuel oil used by the engine. The type of the combustion apparatus that uses the fuel oil specified by the fuel oil management system 1 is not limited to the engine, and any combustion apparatus that inputs fuel oil adjusted to a viscosity within a predetermined range may be used. It may be a type of combustion device. For example, the fuel oil management system 1 may specify the type of fuel oil used by a generator, a boiler, or the like.
