Description

shipping

[0001] The present invention relates to a ship.

[0002] Air pollution is worsening worldwide, and climate change is being driven by it. Because pollutants emitted from ships significantly contribute to air pollution, the International Maritime Organization (IMO), the European Union, the United States, and other countries are strengthening regulations on ship emissions to reduce air pollution.

[0003] As greenhouse gas emission regulations for ships are gradually strengthened at key milestones through 2050, it is expected that existing engines and fuels alone will be unable to comply with regulations on pollutants.

[0004] Therefore, with the implementation of strengthened greenhouse gas emission regulations for ships, the use of existing fossil fuels is expected to become difficult. Therefore, the development of alternative fuels that can meet the strengthened regulations is urgent. Non-fossil fuels such as ammonia (NH3), biofuels, solar energy, and wind energy are currently being considered as alternative fuels.

[0005] Among them, ammonia is a chemical substance that can be produced, stored, transported, and supplied, and an ammonia ship that uses ammonia as fuel is being developed.

[0006] Existing ammonia vessels store ammonia fuel as a liquid. Ammonia has a boiling point lower than room temperature (-33°C at atmospheric pressure). Therefore, storing ammonia in this liquid form requires ammonia storage tanks that meet certain specifications. Furthermore, maintaining a low temperature inside the tanks to maintain the liquid requires cooling, which consumes significant energy.

[0007] In addition, storage tanks for liquid ammonia may generate vapor gas inside the tank, which may increase the pressure inside the storage tank and cause the tank to explode. In addition, if liquid ammonia leaks outside the tank, an explosion may occur, and there is a risk of casualties due to the toxicity of ammonia.

[0008] In this way, existing ammonia ships have problems such as the need to improve facility costs and operating costs for storing liquid ammonia fuel and supplying ammonia fuel to the engine, and in particular, the need to ensure reliable safety.

[0009] The present invention was created to solve the problems of the prior art as described above, and to provide a fuel treatment system and a ship including the same that can ensure safety by appropriately capturing fuel discharged from each component of the system and controlling the discharge of fuel in a safe space when a toxic substance such as ammonia is used as fuel.

[0052] Additionally, it should be noted that terms indicating direction such as front, back, left, right, vertical, and horizontal are defined based on the vessel or hull consisting of the bow, stern, sides (port and starboard), upper deck, and bottom.

[0053] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0054]

[0055] Fig. 1 is a conceptual diagram of a fuel processing system (1) according to a first embodiment of the present invention. Fig. 2 is a conceptual diagram of a fuel neutralization unit in a fuel processing system according to a first embodiment of the present invention. For reference, Figs. 1 and 2 each conceptually illustrate at least a portion of the components included in one embodiment.

[0056] Referring to FIGS. 1 and 2, a fuel processing system (1) according to a first embodiment of the present invention includes a storage unit (10), a fuel supply unit (20), a fuel discharge unit (30), a fuel neutralization unit (40), etc.

[0057] The storage unit (10) stores fuel. At this time, the fuel may be a toxic fuel such as ammonia, but as mentioned above, it is not limited thereto. However, for convenience, the fuel will be described below as a toxic fuel such as ammonia.

[0058] The storage unit (10) can store fuel consumed by a demand source such as an engine (E) or a boiler. In this case, the engine (E) may be an ammonia-only engine (E) or an ammonia-mixed engine (E). Of course, in this specification, the engine (E) is an engine that obtains energy by consuming ammonia, and can encompass turbines, fuel cells, etc.

[0059] The storage unit (10) includes a fuel tank (11), and the fuel tank (11) can store fuel in a liquid state. The fuel is a substance having a boiling point below room temperature and can be liquefied at low temperatures. The storage unit (10) can be insulated on at least one side, either internally or externally, to store the fuel in a liquid state. Alternatively, the fuel tank (11) can prevent fuel from vaporizing by storing the fuel at a high pressure. In this case, the pressurizing means of the fuel supply unit (20), which will be described later, can be reduced or omitted due to the pressure of the fuel tank (11).

[0060] The fuel tank (11) may be provided to form a cargo hold within the vessel. Alternatively, the fuel tank (11) may be an independent tank provided separately within the vessel or on the deck. One or more fuel tanks (11) may be provided, and when multiple fuel tanks (11) are provided, fuel may be consumed alternatively or simultaneously. That is, the fuel tank (11) may be of type A, type B, or type C, and in addition to these independent tanks, the fuel tank (11) may also be provided as a membrane tank.

[0061] A fuel pump (not shown) may be provided inside the fuel tank (11). Of course, the fuel pump may also be provided outside the fuel tank (11), and may be provided both inside and outside the fuel tank (11). The fuel pump may transfer fuel stored in the fuel tank (11) to the fuel supply unit (20).

[0062] Fuel can be supplied to the fuel tank (11) from the bunkering unit (12). The bunkering unit (12) includes a manifold, a loading arm, etc., which are provided on the deck of the ship, etc., and through these, fuel can be delivered from the outside and loaded into the fuel tank (11).

[0063] A loading line (L10) may be provided from the bunkering section (12) to the fuel tank (11), and the loading line (L10) may be insulated to prevent vaporization of liquid fuel flowing into the interior of the fuel tank (11).

[0064] The fuel tank (11) may be a cargo tank installed in the cargo area of ​​the hull, or may be a tank provided separately from the cargo tank. In the latter case, the bunkering unit (12) may transfer fuel from the cargo tank to the fuel tank (11). Additionally, the bunkering unit (12) may return fuel from the fuel tank (11) to the cargo tank, if necessary.

[0065] The fuel supply unit (20) supplies fuel stored in the storage unit (10) to a demander. The fuel supply unit (20) can supply at least liquid fuel among the fuel stored in the fuel tank (11) to an engine (E), etc. In particular, the fuel supply unit (20) can supply fuel in a liquid state to the engine (E), and the fuel supply unit (20) can variously adjust the state of the supplied fuel in response to changes in the specifications of the engine (E), etc.

[0066] The fuel supply unit (20) includes a supply heat exchanger (21), a supply pump (22), a filter unit (23), and a return heat exchanger. The supply heat exchanger (21) can heat or cool the fuel discharged from the fuel tank (11) so that the temperature of the fuel corresponds to the temperature required by the engine (E), etc.

[0067] A supply heat exchanger (21) can be provided between the fuel pump and a supply pump (22) to be described later, and considering that some temperature increase occurs when the fuel is pressurized by the supply pump (22), the heating / cooling of the supply heat exchanger (21) can be controlled.

[0068] The supply pump (22) pressurizes the fuel discharged from the fuel tank (11) by the fuel pump. The supply pump (22) can pressurize the fuel in response to the pressure required by the engine (E). The supply pump (22) can be provided downstream of the supply heat exchanger (21) and can receive fuel having a temperature higher than the boiling point. However, since the fuel is sufficiently pressurized by the fuel pump, it may not vaporize even if heated in the supply heat exchanger (21). Therefore, the supply pump (22) can receive liquid fuel from the supply heat exchanger (21), pressurize it, and then supply it to the engine (E).

[0069] Of course, the arrangement of the supply pump (22) may differ from the previous case. The supply pump (22) may be installed upstream of the supply heat exchanger (21). Alternatively, the supply pumps (22) may be installed upstream and downstream of the supply heat exchanger (21).

[0070] The filter unit (23) is provided downstream of the supply pump (22) and can filter out foreign substances contained in the fuel. Here, the foreign substances may refer to any substance that may affect the operation of the engine (E), and further, may include any substance other than fuel in the fluid supplied to the engine (E).

[0071] A fuel supply line (L20) extends from a fuel pump provided in a fuel tank (11), and a supply heat exchanger (21), a supply pump (22), a filter unit (23), etc. may be provided on the fuel supply line (L20). Accordingly, the fuel is discharged from the fuel tank (11) while being pressurized by the fuel pump, heated in the supply heat exchanger (21), pressurized in the supply pump (22), and then supplied in a liquid state to the engine (E).

[0072] The engine (E) may combust some of the fuel supplied through the fuel supply line (L20), generating excess fuel. The excess fuel is fuel that has been supplied to the engine (E) but has not been combusted within the engine (E). As it passes through at least a portion of the engine (E), it may contain lubricating oil used in the engine (E).

[0073] Excess fuel is recovered from the engine (E) to the fuel supply unit (20). Fuel is introduced into the engine (E) through a fuel supply line (L20), and excess fuel can be recovered through a fuel recovery line (L21) extending from the engine (E) to the fuel supply unit (20).

[0074] The fuel recovery line (L21) may be connected to the fuel supply line (L20). Fuel flowing in through the fuel recovery line (L21) may be re-introduced into the engine (E) without being delivered to the fuel tank (11) because it contains lubricating oil. The fuel recovery line (L21) may be connected upstream of the supply pump (22) in the fuel supply line (L20).

[0075] A fuel recovery line (L21) may be provided with a recovery heat exchanger (24). The recovery heat exchanger (24) can cool the fuel heated while passing through the engine (E) to a temperature suitable for introduction into the supply pump (22). In other words, the recovery heat exchanger (24) may be a cooler and may share a medium with the supply heat exchanger (21).

[0076] A supply valve train (SVT) may be provided upstream of the engine (E) in the fuel supply line (L20), and a return valve train (RVT) may be provided downstream of the engine (E) in the fuel return line (L21). The supply valve train and the return valve train may be collectively referred to as a fuel valve train (FVT).

[0077] The fuel discharge unit (30) discharges fuel between the storage unit (10) and the engine (E). The fuel discharge unit (30) can drain fuel remaining in the fuel supply unit (20) or discharge fuel together with purging gas by purging the fuel supply unit (20). In other words, the fuel discharge unit (30) can perform functions such as draining and purging.

[0078] The fuel discharge unit (30) can discharge fuel while the engine (E) is stopped, or can process fuel discharged from the storage unit (10) or fuel supply unit (20) to relieve overpressure.

[0079] The fuel discharge unit (30) may include an inert gas supply unit (31), a recovery fuel discharge unit (32), and a residual fuel discharge unit (33). The inert gas supply unit (31) may supply inert gas to a fuel supply line (L20) of the fuel supply unit (20), etc., in order to forcibly discharge fuel remaining in the fuel supply unit (20) or the engine (E).

[0080] The inert gas supply unit (31) can supply nitrogen or inert gas, etc., and can be connected to one or more points in the fuel supply unit (20). The inert gas supply unit (31) can be connected to a downstream location of the supply pump (22) in the fuel supply line (L20). In addition, the inert gas supply unit (31) can also be added to the loading line (L10) between the bunkering unit (12) and the fuel tank (11).

[0081] The recovery fuel discharge unit (32) can recover the fuel remaining in the fuel supply unit (20) when the fuel supply by the fuel supply unit (20) is interrupted due to a stop of the engine (E), etc. The recovery fuel discharge unit (32) can recover the remaining fuel in the fuel supply line (L20) and the fuel recovery line (L21), and recovers the fuel together with the inert gas.

[0082] The recovery fuel discharge unit (32) includes a separator (321), a buffer tank (322), etc. The separator (321) can be branched and connected from a fuel recovery line (L21). A recovery fuel discharge line (L31) can be branched from the fuel recovery line (L21), and the recovery fuel discharge line (L31) can be connected to a fuel neutralization unit (40) after passing through the separator (321) and the buffer tank (322), etc.

[0083] When an inert gas is supplied downstream of a supply pump (22) in a fuel supply line (L20), fuel remaining in a portion of the fuel supply line (L20), inside the engine (E), and in the fuel recovery line (L21) may flow into the separator (321) together with the inert gas. The separator (321) may be provided as a pressurized type, and may store the inert gas and fuel, etc. at a certain pressure higher than the atmospheric pressure.

[0084] The separator (321) can implement the function of a gas-liquid separator, and the inert gas can be discharged as a gas and the fuel can be discharged as a liquid. The liquid discharged from the separator (321) can be transferred again to the fuel recovery line (L21) or the fuel supply line (L20). The liquid transferred from the separator (321) to the fuel recovery line (L21) can be combined upstream of the recovery heat exchanger (24). At this time, the liquid transferred from the separator (321) to the fuel recovery line (L21) may be mixed with lubricating oil mixed in from the engine (E).

[0085] On the other hand, the inert gas separated in the separator (321) can be discharged to the atmosphere or delivered to the fuel tank (11). The internal pressure of the fuel tank (11) may increase somewhat as the inert gas is injected, and the fuel tank (11) may withstand the internal pressure without discharging the gas phase, or discharge the gas phase to the re-liquefaction unit or the outside, depending on the type.

[0086] A buffer tank (322) may be provided downstream of the separator (321). The buffer tank (322) may be used as a gas-liquid separator, similar to the separator (321). However, since the separator (321) has primarily separated the inert gas, fuel, lubricant, etc., the buffer tank (322) may not return the liquid to the fuel supply unit (20). The inert gas and fuel may be introduced into the buffer tank (322), and the buffer tank (322) may transfer the inert gas to the fuel tank (11), etc., and transfer the fuel, etc. to the fuel neutralization unit (40).

[0087] The residual fuel discharge unit (33) can recover the residual fuel remaining in the engine (E) when the engine (E) is stopped. Although both the recovery fuel discharge unit (32) and the residual fuel discharge unit (33) recover the fuel remaining in the engine (E), they can be used at different times. For example, the recovery fuel discharge unit (32) can recover fuel when the engine (E) is normally stopped, and the residual fuel discharge unit (33) can recover fuel when the engine (E) is in an emergency stop.

[0088] The residual fuel discharge unit (33) can recover the fuel remaining in the engine (E) through the residual fuel discharge line (L30) branching from the fuel recovery line (L21). The residual fuel discharge unit (33) can include a knockout drum (331). When an inert gas is injected upstream of the engine (E) from the fuel supply line (L20), the knockout drum (331) can recover the inert gas passing through the engine (E) together with the residual fuel of the engine (E).

[0089] The knockout drum (331) can implement a gas-liquid separator function, similar to the separator (321). The knockout drum (331) can separate the lubricating oil used in the engine (E), and the lubricating oil can be reintroduced into the engine (E) through the fuel supply unit (20), etc. In addition, the knockout drum (331) can separate the inert gas and fuel, and the inert gas, etc. can be delivered to the fuel tank (11).

[0090] Fuel separated from the knockout drum (331) can be delivered to the fuel neutralization unit (40). Fuel connected from the recovery fuel discharge unit (32) to the fuel neutralization unit (40) and fuel connected from the residual fuel discharge unit (33) to the fuel neutralization unit (40) can be handled and processed differently.

[0091] The fuel neutralization unit (40) neutralizes toxic fuel. The fuel neutralization unit (40) can dilute or eliminate toxicity of toxic fuel by supplying a preventive agent (e.g., a neutralizer). Fuel is a toxic substance and cannot be directly released into the atmosphere, but can only be released within a certain concentration standard (e.g., 25 ppm). Therefore, the fuel neutralization unit (40) can mix water or seawater, which are preventive agents, with the fuel to release the fuel into the atmosphere.

[0092] The fuel neutralization unit (40) can limit the discharge of fuel so that fuel below a certain concentration standard is discharged into the atmosphere, and can also store wastewater mixed with fuel and disaster prevention materials. In this case, the wastewater can be unloaded and treated when the vessel is anchored on land or at a port. Hereinafter, wastewater refers to a mixture of fuel and disaster prevention materials, and the wastewater may be, for example, ammonia water.

[0093] The fuel neutralization unit (40) includes a scrubber (41), an absorption tank (42), and a wastewater tank (43). The scrubber (41) supplies a fire retardant to the fuel so that the fuel dissolves in the fire retardant. If the fuel is ammonia, considering that ammonia easily dissolves in water, the scrubber (41) can supply seawater or water. If seawater is used as the fire retardant, the scrubber (41) can be made of a corrosion-resistant material, or water can be used to eliminate the possibility of corrosion.

[0094] Fuel discharged from the fuel supply unit (20), etc., can be introduced into the scrubber (41). A disaster prevention material supply line (L41) is connected to the scrubber (41), and the disaster prevention material supply line (L41) can be connected to the upper part of the scrubber (41). Water, which is a disaster prevention material, can be sprayed from the upper part of the scrubber (41), and fuel can be introduced from the lower part. Fuel introduced into the scrubber (41) can be dissolved in water sprayed from the upper part to produce ammonia water.

[0095] The water supplied to the scrubber (41) may be fire-fighting water provided on the ship, or may be water provided in the ship's fresh water tank. In other words, the fire-fighting material supplied to the scrubber (41) may be water used for other purposes on the ship.

[0096] The scrubber (41) can receive fuel delivered from the fuel supply unit (20) or the fuel discharge unit (30). One or more scrubbers (41) can be provided, and when a plurality of scrubbers (41) are provided, one scrubber (41a) can receive gas delivered from the recovery fuel discharge unit (32), and another scrubber (41b) can receive gas delivered from the residual fuel discharge unit (33).

[0097] At least one scrubber (41b) may be provided with an absorption tank (42). The absorption tank (42) may be provided at the bottom of the scrubber (41b). The absorption tank (42) may store a certain level of disaster prevention material, and fuel may be introduced into or above the disaster prevention material from the absorption tank (42). A separate disaster prevention material supply line (not shown) may be provided inside the absorption tank (42), and a disaster prevention material such as water may be filled at a certain level inside the absorption tank (42). At this time, the level of the disaster prevention material may be managed at an appropriate level by a sensor or the like provided in the absorption tank (42).

[0098] At least one scrubber (41b) can be configured such that the fuel flowing into it is dissolved in water sprayed from above to generate ammonia water and store it in an absorption tank (42). The ammonia water stored in the absorption tank (42) can be recirculated back to the scrubber (41b) to lower the ammonia concentration in the ammonia water.

[0099] Additionally, the absorption tank (42) may be connected to a wastewater tank (43). The ammonia water stored in the absorption tank (42) may be introduced into the wastewater tank (43). The ammonia water stored in the wastewater tank (43) may also be introduced back into the absorption tank (42) and configured to lower the ammonia concentration through a scrubber (41b).

[0100] The liquid level of the absorption tank (42) is monitored in real time by a level switch (LS), etc., and the liquid stored in the absorption tank (42) can be transferred to the wastewater tank (43) according to the liquid level. A wastewater transfer line (L40) can be provided between the absorption tank (42) and the wastewater tank (43), and a wastewater transfer valve (421) can be provided in the wastewater transfer line (L40). The wastewater transfer valve (421) can be opened and closed or its opening degree can be adjusted according to the liquid level of the absorption tank (42).

[0101] However, another scrubber (41a) may be connected to the wastewater tank without passing through the absorption tank (42). That is, a wastewater delivery line (L40) may be provided from at least two scrubbers (41a, 41b) toward the wastewater tank (43), and the wastewater delivery line (L40) may pass through the absorption tank (42) on one side. The ammonia water generated from the fuel flowing into the other scrubber (41a) may be passed into the absorption tank (42) or the wastewater tank (43). If the ammonia concentration of the ammonia water generated from the fuel flowing into the other scrubber (41a) is high, it may be configured to be recycled back to one of the scrubbers (41b) to lower the ammonia concentration.

[0102] The wastewater tank (43) stores wastewater. The wastewater tank (43) can receive wastewater delivered from the scrubber (41). The wastewater tank (43) can store a certain level of wastewater, and at least a portion of the fuel contained in the wastewater can be vaporized within the wastewater tank (43). In this case, the vaporized fuel in the wastewater tank (43) can be circulated to the scrubber (41) or the absorption tank (42).

[0103] A gas circulation line (L42) may be provided between the wastewater tank (43) and the absorption tank (42). Fuel that has been dissolved by the disaster prevention material in the scrubber (41) or the absorption tank (42) and then separated again in the wastewater tank (43) may be reintroduced into the absorption tank (42) and dissolved again by the disaster prevention material. Accordingly, the concentration of fuel in the wastewater tank (43) may be controlled within a certain level.

[0104] Some of the fuel vaporized in the wastewater tank (43) may be discharged into the atmosphere through the vent mast (44). A vent line (L43) is connected from the wastewater tank (43) to the vent mast (44), and the fuel flowing along the vent line (L43) can be controlled so that its concentration does not exceed the concentration according to environmental regulations. At this time, the control can be achieved by controlling the concentration inside the wastewater tank (43) and controlling the flow rate discharged from the vent line (L43). When the volume of the wastewater tank (43) is sufficiently large, a separate disaster prevention material may be supplied to the wastewater tank (43) in addition to the wastewater delivered from the scrubber (41) or the absorption tank (42). Through this, the concentration of the fuel in the gas vaporized in the wastewater tank (43) can be controlled.

[0105] The wastewater tank (43) may be provided by utilizing a tank already provided on the hull. For example, the wastewater tank (43) may be formed by at least one of a bow peak tank, a stern peak tank, or a ballast tank provided on the hull.

[0107]

[0108] Below, a vessel (2) according to a second embodiment of the present invention will be described with reference to FIGS. 3 to 9.

[0109] Below, the differences between this embodiment and the previous embodiment will be explained, and any omitted parts will be replaced with the previous content. Please note that this also applies to other embodiments below.

[0110] For reference, the vessel (2) according to the second embodiment of the present invention of FIGS. 3 to 9 may correspond to at least a part of the configurations included in the first embodiment of the present invention described above, or may be connected to at least a part of them.

[0111] In addition, the fuel used in the ship (2) according to the second embodiment of the present invention may be a toxic fuel such as ammonia, but is not limited thereto. However, for convenience, the fuel is described below as a toxic fuel, i.e., ammonia.

[0112] Fig. 3 is a side view of a vessel according to a second embodiment of the present invention. Fig. 4 is a cross-sectional view of the lower part of the stern side of a vessel according to a second embodiment of the present invention.

[0113] Referring to FIGS. 3 and 4, a ship (2) according to a second embodiment of the present invention includes a hull (222), an engine room (100), an auxiliary fuel tank (113, 117), and a slop tank.

[0114] A fuel tank (1) and multiple crude oil storage tanks (120) may be provided in the hull (222).

[0115] The fuel tank (1) can store toxic fuel.

[0116] Crude oil can be stored in the crude oil storage tank (120).

[0117] A plurality of crude oil storage tanks (120) may be provided and placed at the center and sides of the hull (222).

[0118] The interior of the crude oil storage tank (120) may include vertical and horizontal bulkheads to control the flow of crude oil.

[0119] The crude oil storage tank (120) is connected to a pipe and valve system for loading and unloading cargo, and a ventilation device, a gas detector, and an explosion prevention device may be provided for safety.

[0120] The engine room (100) is provided at the stern of the hull (222) and can accommodate a demand source that uses toxic fuel.

[0121] The auxiliary fuel tank (113, 117) is provided at the front of the engine room (100) and can store auxiliary fuel.

[0122] Auxiliary fuels may include Marine Gas Oil (MGO), Light Fuel Oil (LFO), and Heavy Fuel Oil (HFO).

[0123] A vessel (2) according to the second embodiment of the present invention can use toxic fuel (e.g., ammonia, etc.) as the main fuel, and can selectively use auxiliary fuel depending on the operating environment or regulations.

[0124] MGO is a low-viscosity fuel based on diesel fuel that can be used at room temperature. Its low sulfur content makes it easy to comply with environmental regulations and can be used primarily as an auxiliary power generator and in port operations.

[0125] LFO is a light fuel oil with a higher viscosity than MGO, a slightly higher sulfur content but lower than HFO, and may require heating or blending due to its high viscosity.

[0126] The slop tank is provided in front of the auxiliary fuel tank (113, 117) and can store crude oil or slop.

[0127] The slop tank is a tank for temporarily storing cleaning water or a mixture of residual oil, and can collect contaminated water, cleaning water, oil residue, etc. generated during the cleaning process of the crude oil storage tank (120).

[0128] A cofferdam (115) may be provided between the auxiliary fuel tank (113, 117) and the slop tank.

[0129] The cofferdam (115) is provided to cover the front of the auxiliary fuel tank (113, 117) and can prevent heat inside the slop tank from being transferred to the auxiliary fuel tank (113, 117).

[0130] The interior of the slop tank is heated for viscosity management, and the cofferdam (115) can prevent the heat of the slop tank from being transferred to the auxiliary fuel tank (113, 117).

[0131] A vessel (2) according to the second embodiment of the present invention may further include a pump room (121).

[0132] The pump room (121) is provided at the lower front side of the engine room (100) and can accommodate a pump for transporting crude oil.

[0133] The pump room (121) is a space installed to transport cargo from a ship (2), and pumps mainly used for unloading crude oil or liquefied gas can be placed there.

[0134] The pump room (121) can be installed adjacent to the rear of the crude oil storage tank (120).

[0135] The auxiliary fuel tank (113, 117) may be arranged adjacent to the pump room (121).

[0136] The auxiliary fuel tank (113, 117) may include a first tank (113) for storing a first fuel and a second tank (117) for storing a second fuel having a higher viscosity than the first fuel.

[0137] The first tank (113) can store MGO.

[0138] The second tank (117) can store LFO.

[0139] A cofferdam (115) can be provided in front of the first tank (113).

[0140] That is, in the case of MGO, since it is a fuel oil with relatively low viscosity and light weight compared to LFO, the viscosity may become too low when heated excessively due to the characteristics of the fuel, which may cause leakage or excessive combustion in the fuel pump or injector, and thus, heat is prevented from being transferred from the slop tank to the first tank (113) through the cofferdam (115).

[0141] On the other hand, in the case of LFO, since it is a high viscosity and heavy fuel oil, it is difficult to spray or pump due to its high viscosity, so it must be heated to an appropriate temperature to lower the viscosity so that it can be sprayed and burned normally in the fuel pump and combustor, and the heat transferred from the slop tank can be utilized in the second tank (117).

[0142] The first tank (113) and the second tank (117) can be provided on both sides of the pump room (121).

[0143] The first tank (113) can be installed on the starboard side centered around the pump room (121).

[0144] The second tank (117) can be installed on the port side centered around the pump room (121).

[0170] A gas circulation line may be provided between the wastewater tank (153) and the absorption tank.

[0171] Fuel that has been dissolved by a neutralizing agent in a scrubber or absorption tank and then separated again in a wastewater tank (153) can be reintroduced into the absorption tank and dissolved again by a neutralizing agent.

[0172] Therefore, the concentration of fuel in the wastewater tank (153) can be controlled within a certain level.

[0173] Some of the fuel vaporized in the wastewater tank (153) may be discharged into the atmosphere through the vent mast.

[0174] A vent line is connected from the wastewater tank (153) to the vent mast, and the fuel flowing along the vent line can be controlled so that the concentration does not exceed the concentration according to environmental regulations.

[0175] At this time, control can be achieved by controlling the concentration inside the wastewater tank (153) and controlling the flow rate discharged from the vent line.

[0176] If the volume of the wastewater tank (153) is sufficiently large, a separate neutralizing agent may be supplied to the wastewater tank (153) in addition to the wastewater delivered from the scrubber or absorption tank.

[0177] Through this, the concentration of fuel in the gas vaporized within the wastewater tank (153) can be controlled.

[0178] The wastewater tank (153) can be provided by utilizing a tank already provided in the hull (222).
