On the deck 19, in the information of the engine room 4, a living quarter 22 for the crew to live is provided. A scrubber 23 for treating the exhaust gas generated by the equipment 16 is provided near the accommodation space 22 .

Next, a ship control system 100 according to an embodiment of the present invention will be described with reference to FIG. FIG. 2 is a diagram showing a block configuration of the ship control system 100 according to the embodiment of the invention. As shown in FIG. 2 , the ship control system 100 includes a control section 30 , an alarm output section 35 and an inboard system 40 .

The alarm output unit 35 is a device for outputting an alarm. The alarm output unit 35 may output visual information using, for example, a monitor or a warning light. Also, the alarm output unit 35 may output auditory information using a speaker, an alarm, or the like. The alarm output unit 35 outputs an alarm having contents based on the alarm information acquired from the control unit 30 .

The inboard system 40 is various systems provided in the ship 1 . The inboard system 40 controls systems that require control based on control signals from the control unit 30 . The onboard system 40 includes a domestic water control system 41 , a ballast water control system 42 , a scrubber control system 43 , an exhaust control system 44 and a noise control system 46 . The details of the control of the inboard system 40 will be described later.

The control unit 30 is a device that performs various calculations for controlling the ship 1 . The control unit 30 includes a processor, memory, storage, and communication interface, and is configured as a general computer. The processor is a calculator such as a CPU (Central Processing Unit). The memory is a storage medium such as ROM (Read Only Memory) or RAM (Random Access Memory). The storage is a storage medium such as an HDD (Hard Disk Drive). A communication interface is a communication device that implements data communication. The processor controls memory, storage, and communication interface, and implements the functions of the control unit 30, which will be described later. The control unit 30 implements various functions by, for example, loading programs stored in the ROM into the RAM and executing the programs loaded into the RAM by the CPU. The control unit 30 may be composed of a plurality of computers. The control unit 30 includes a position information acquisition unit 31 , an operating area information acquisition unit 32 , an inboard system control unit 33 and a database 34 .

The position information acquisition unit 31 acquires position information indicating the position of the ship 1 . The position information acquisition unit 31 acquires position information from a measurement system such as GPS. In addition, the position information acquisition unit 31 can also acquire the scheduled operation position (and its scheduled timing) at which the ship 1 is scheduled to operate based on the current operation information and route plan information.

The operating area information acquisition unit 32 acquires operating area information regarding an area in which the ship 1 is operating or scheduled to operate. The operational area is an area in which the ship 1 operates, and indicates a sea area, a harbor, or the like when the ship 1 operates on the sea. The operational domain information includes, for example, information such as regulations, standards, and prohibited items set in the operational domain. The operational area information may also include information such as characteristics of the operational area, and may include information such as whether seawater is freshwater, for example. The operating area information acquiring unit 32 acquires operating area information by referring to information stored in the database 34 for the position information acquired by the position information acquiring unit 31 . In this way, the database 34 stores operational domain information for each operational domain.

Further, the operational domain information acquisition unit 32 extracts alarm information from the operational domain information, and controls the alarm output unit 35 to output an alarm at the required timing. Thereby, the alarm output unit 35 outputs an alarm based on the operational area information acquired by the operational area information acquisition unit 32 . For example, when the operational domain information acquisition unit 32 acquires information such as standards and prohibited items as the operational domain information, it extracts notifications, warnings, and the like of matters that the crew should pay attention to as alarm information.

Operation area information will be described with reference to FIG. FIG. 3 is a nautical chart showing the state of the sea where the ship 1 navigates. As shown in FIG. 3, there are a designated sea area A, a designated sea area B, and a designated sea area C depending on the location. These sea areas have their own regulations and standards, and it is necessary to set alarm information corresponding to them. For example, alarm information N, A and D are set for the designated sea area A, alarm information N and B are set for the designated sea area B, alarm information N, C and A are set for the designated sea area C, and other Alarm information N is set for the sea area. Here, the alarm information N may refer to alarm information that is indispensable in all sea areas. For example, when the ship 1 is sailing in the designated sea area B, the operational area information acquisition unit 32 acquires the operational area information of the designated area B from the database 34 and extracts the alarm information N and B therefrom.

The inboard system control unit 33 controls the inboard system 40 based on the operating area information acquired by the operating area information acquiring unit 32 . That is, the inboard system control unit 33 controls the inboard system based on the operating area information in which the vessel 1 operates and the operating area information in which the vessel 1 is scheduled to operate so that the operation can be automatically performed in a suitable manner in the operating area. Control system 40; The onboard system control unit 33 may perform control corresponding to the alarm information in conjunction with the generation of the alarm by the alarm output unit 35 . Note that depending on the alarm information, the alarm output unit 35 may output a warning alarm in advance before the vessel 1 enters the designated sea area.

The inboard system control unit 33 controls the event of discharge or supply from the ship 1 according to the operating area. For example, the inboard system control unit 33 can control the discharge mode of the liquid and the intake mode of the liquid into the vessel.

Specifically, the discharge mode of domestic water discharged from the ship 1 may be controlled. In some sea areas (for example, the Black Sea), the discharge of gray water is prohibited. In this case, it becomes impossible for the sailors to discharge the domestic wastewater from the ship 1 after they have finished using it. When the ship 1 enters such a sea area, the operational area information acquisition unit 32 acquires information indicating that discharge of domestic water is prohibited as operational area information. In response to this, the alarm output unit 35 sounds an alarm to prohibit the discharge of domestic water. Further, the inboard system control unit 33 controls the domestic water control system 41 so as to stop the discharge of domestic water. The domestic water control system 41 includes, for example, a domestic water supply system and a domestic water drainage system. The domestic water control system 41 controls a valve or the like so that the used domestic water does not flow to the drain port that discharges the domestic water to the sea. The domestic water control system 41 also stores used domestic water in a tank or the like.

Also, the manner in which ballast water is taken into the ship 1 may be controlled. The seawater taken into the ballast tank 27 has a salt concentration above a certain level and needs to be electrolyzed. Therefore, if a sea area into which fresh water flows exists in the planned route, ballast water cannot be taken in in the sea area. When the ship 1 is approaching such a sea area, the alarm output section 35 issues an advance warning before entering the sea area. The operating area information acquisition unit 32 acquires information indicating that the area is a freshwater area into which freshwater flows as operating area information. Further, the inboard system control unit 33 controls the ballast water control system 42 so as to take seawater into the ship 1 before reaching the freshwater area. Thereby, the ballast water control system 42 can take in seawater while the salinity is high. The ballast water control system 42 has a pump 17 in the pump room 5 . The ballast water control system 42 controls the pump 17 to take in seawater with a high salt concentration from the sea chest and supplies it to the ballast tanks 27 before entering the freshwater sea area.

Moreover, the discharge mode of the scrubber waste water discharged from the ship 1 may be controlled. Depending on the sea area, there are cases where standards for wastewater from scrubbers are set in addition to those stipulated by the IMO. In this case, when the vessel 1 enters the sea area, the operational area information acquisition unit 32 acquires information on the scrubber drainage standard as the operational area information. Then, the alarm output unit 35 issues a warning to the effect that scrubber drainage cannot be performed. Further, the onboard system control unit 33 controls the scrubber control system 43 so as to stop scrubber drainage. The scrubber control system 43 includes a water supply system and a drainage system used in exhaust treatment in the scrubber 23 . The scrubber control system 43 controls a valve or the like so that the scrubber drainage does not turn around to the outlet that discharges the scrubber drainage to the sea. The scrubber control system 43 also stores the treated scrubber waste water in a tank or the like.

Further, the operational domain information acquisition unit 32 may acquire exhaust regulation information as the operational domain information. At this time, the inboard system control unit 33 controls the processing mode of the exhaust. NOx reduction processing of the exhaust gas from the scrubber 23 is controlled. In other words, although NOx is regulated in all sea areas by the IMO's secondary regulation of NOx, it is even stricter when passing through the ECA (Emission Control Area: within 200 nautical miles of the coasts of North America and Canada and the Caribbean Sea). Tertiary regulations apply. Therefore, in the sea area, the inboard system control unit 33 controls the exhaust control system 44 after the alarm is aroused. Specifically, the exhaust control system 44 responds by automatically activating SCR (Selective Catalytic Reduction). The processing is performed at the timing when it is detected in advance (about two hours before) that the vessel approaches the sea area on the sea route. The exhaust control system 44 heats some equipment (reactor, etc.) for about two hours to promote the chemical reaction. When entering a sea area, the exhaust control system 44 automatically operates a valve to send the exhaust gas to the SCR to treat NOx and urea water by reaction.

Further, the operating area information acquisition unit 32 may acquire noise regulation information as the operating area information. At this time, the inboard system control unit 33 controls the operation mode. A driving mode for reducing noise emitted from the ship 1 is controlled. In recent years, it has been reported that underwater noise from the ship 1 may affect marine life. If regulations on noise are set, underwater noise will need to be reduced in controlled ports and sea areas. Therefore, the onboard system control unit 33 controls the noise control system 46 so as to reduce the noise from the ship when there is a possibility of entering the operation area of the noise regulation (when the noise regulation information is acquired). The noise control system 46 suppresses noise by attenuating or stopping the operation of mechanisms that cause noise in the ship 1 . For example, noise control system 46 reduces the propeller speed of propeller 12 . Alternatively, the output of the thruster 12 itself may be reduced.

Next, with reference to FIG. 4, the control contents of the ship control system 100 will be described. As shown in FIG. 4, first, the operational area information acquisition unit 32 confirms the current position of the ship 1 and the route based on the position information acquired by the position information acquisition unit 31 (step S10). Then, the operating area information acquiring unit 32 acquires operating area information by collating the execution confirmed in step S10 with the information stored in the database 34 (step S20). Further, the operational domain information acquisition unit 32 extracts alarm information from the operational domain information, and the alarm output unit 35 outputs an alarm (step S30). Then, the inboard system control unit 33 controls the inboard system 40 in an appropriate manner based on the operating area information acquired in step S20 (step S40). Thus, the processing shown in FIG. 4 ends.
