Description

[0001] The present invention relates to a container carrier capable of mounting an LNG fuel propulsion system,

The present invention relates to a container carrier capable of mounting an LNG fuel propulsion system.

A ship is a means of transporting large quantities of minerals, crude oil, natural gas, or more than a thousand containers. It is made of steel and buoyant to float on the water surface. ≪ / RTI >

Such a ship generates thrust by driving the engine. At this time, the engine uses gasoline or diesel to move the piston so that the crankshaft is rotated by the reciprocating motion of the piston, so that the shaft connected to the crankshaft is rotated, .

However, when heavy oil such as HFO or MFO is used as propellant fuel, environmental pollution due to various harmful substances contained in exhaust gas is serious when burning heavy oil, etc., and regulations on environmental pollution are strengthened, The regulations on propulsion devices using fuel oil are also strengthened, and the cost for satisfying these regulations is gradually increasing.

Accordingly, instead of using heavy oil or using only a minimum amount of fuel as a fuel for a ship, it is possible to replace gasoline or diesel with liquefied natural gas, liquefied petroleum gas The same liquefied gas is used and the technology is being developed.

Such liquefied gas is stored in a liquefied gas storage tank installed on the ground or stored in a liquefied gas storage tank provided in a ship which is a means of transporting the ocean. The liquefied natural gas is liquefied to a volume of 1/600 The liquefaction of liquefied petroleum gas has the advantage of reducing the volume of propane to 1/260 and the content of butane to 1/230, resulting in high storage efficiency.

These liquefied gases are supplied to various customers and used. Recently, LNG carrier that uses LNG as fuel for LNG carriers that transport liquefied natural gas has been developed. Attempts have been made to apply this method to other vessels other than LNG carriers.

In addition, efforts are also being made to improve fuel efficiency, reduce emissions, and improve operational efficiency through the use of liquefied gas engines in container carriers.

As mentioned above, the majority of ships that propel LNG as fuel are due to the LNG price being lower than that of diesel fuel. However, as the price of diesel fuel has fallen more than that of LNG due to the recent fluctuation of the oil price market, ship owners want to build vessels to use diesel only without costly LNG fuel supply system.

However, due to the environmental regulations of IMO such as Tier Ⅲ, the introduction of LNG fuel supply system is sure to be introduced. As a result, ship owners who propelled the ship using diesel fuel should newly build a ship to propel liquefied gas as fuel , There is a problem that the drying cost is enormous due to the nature of the shipbuilding business.

Therefore, it is necessary to improve the performance of the existing diesel fuel propulsion vessel so that the LNG fuel supply system can be built on the vessel at any time, so that the vessel can be easily changed to the liquefied gas fuel propulsion vessel. .

The present invention provides a container carrier capable of mounting a retrofit LNG fuel propulsion system to facilitate redesign by liquefied gas fuel propulsion in diesel fuel propulsion.

The container carrier capable of mounting the LNG fuel propulsion system according to the present invention comprises: a hull; An engine room provided on the hull; A main engine provided in the engine room to provide propulsion power of the ship; A plurality of auxiliary engines provided in the engine room and capable of using different types of fuel (LNG and diesel) to produce electricity to the ship; And a LNG fuel supply device for supplying LNG to the diesel fuel supply device for supplying diesel to the plurality of auxiliary engines, wherein when the main engine is changed to a heterogeneous fuel engine, And the space is provided as an empty space.

Herein, the machine room is provided with various mechanical devices such as a control room (not shown) for controlling other devices, machines or electronic devices required by the container carrier 1. The diesel fuel storage tank 30 is a separate Can be separated by the partition wall. In the present invention, the mechanical chamber is described above the diesel fuel storage tank 30, but the present invention is not limited thereto. The mechanical chamber may be disposed inside the cabin 20 or in a separate empty space.

More specifically, the diesel fuel storage tank 30 is divided into a left hull (not shown) and a right hull (not shown) of the hull 10 by a watertight transverse bulkhead structure (not shown) The upper portion is formed by the cabin 20 and the lower portion is surrounded by the bottom portion 11.

The space in which the diesel fuel storage tank 30 is disposed may be a half of the space of the cargo hold 50 space or a space the same or similar size as the first bay 51 or the second bay 52. Here, the watertight transverse bulkhead structure is a watertight transverse bulkhead structure, which will be described in detail in the bay 60.

The diesel fuel storage tank 30 can be connected to the diesel fuel supply line 31 downwardly and can be accommodated in the internal space between the bottom inner plate 111 and bottom bottom shell 112 of the bottom 11, And extend to the propulsion engine 41 of the room 40.

The engine room 40 includes a propulsion engine 41 that supplies power to the hull 10, a power generation engine 42 that generates power to be supplied to various electronic devices provided in the hull 10, An engine control room (ECR) for controlling the engine 41 and the engines 41 and 42 can be provided and four horizontal decks (first through fourth decks 12.401, 402 and 111) Can be partitioned.

The engine room 40 is described in detail below with reference to Figs.

The engine room 40 is provided with a horizontal deck in the order of the second deck 401, the third deck 402 and the fourth deck 111 (bottom inner plate) from the first deck 12 (upper deck) downward. (See Fig. 4)

A boiler 43 is installed between the first deck 12 and the second deck 401 and a container C and an engine control room 45 are provided in the front space of the boiler 43 . At this time, the engine control room 45 may be provided such that the containers C are stacked on both sides, and the boiler 43 and the engine control room 45 may be supported by the second deck 401 have. (See Fig. 6)

Between the first deck 12 and the second deck 401 there is provided a GVU installation space 447 (a third backup (not shown)) for additional provision of a gas control (not shown) for controlling the supply of LNG to the boil- Space) may be provided.

When the next container carrier 1 uses LNG as propellant, the boiler 43 can also use LNG as fuel. To this end, a gas control unit or GVU is required to supply LNG to the boiler 43 as well.

Therefore, in the embodiment of the present invention, the gas to the boil-off road 43 is supplied to the first deck 12 and the second deck 401 in comparison with the case in which the LNG is used as the propellant fuel, A space for installing a gas control unit for controlling the supply of LNG, that is, a GVU installation space 447 is provided.

Therefore, in the case of using LNG as the next propellant fuel, the container carrier 1 according to the embodiment of the present invention does not require a separate design change in order to use the LNG as the fuel in the boiler 43, Since the gas control unit (GVU) is installed in the GVU installation space 447 which is a space, the drying period is drastically reduced and the drying cost is remarkably reduced.

A power generation engine 42 (auxiliary engine) may be installed between the second deck 401 and the third deck 402 and at least a part of the propulsion engine 41 (main engine) may be accommodated. At this time, a plurality of power generation engines 42 may be provided and supported by the third deck 402 and disposed on both sides of the propulsion engine 41. The propulsion engine 41 can be received at least partly through the third deck 402. (See Figs. 5A to 5C)

Further, a diesel fuel auxiliary tank 32 may be provided between the second deck 401 and the third deck 402. The diesel fuel auxiliary tank 32 is supported by the third deck 402 and can be disposed in front of the power generation engine 41. [ (See Figs. 5A to 5C)

Between the second deck 401 and the third deck 402 is provided a GVU installation space 441 (not shown) for additionally providing a gas control unit (not shown) for controlling the gas supply to the propulsion engine 41 and the power generation engine 42 A second backup space), and a GVT installation space 442 (fourth backup space) may be provided (see Figs. 5B and 5C).

When the next container carrier 1 is to use LNG as the propellant fuel, the propulsion engine 41 and the power generation engine 42 must use LNG as the fuel. To this end, a gas control unit, that is, a gas valve train (for a propulsion engine) and a gas valve unit (for a power generation engine) are required to supply LNG to the propulsion engine 41 and the power generation engine 42.

The second deck 401 and the third deck 402 are provided with the propulsion engine 41 and the power generation engine 41. The second deck 401 and the third deck 402 are provided with a propulsion engine 41, That is, a GVU installation space 441 and a GVT installation space 442, in which a gas control unit for controlling the supply of gas (LNG)

Therefore, in order to use the LNG as fuel for the propulsion engine 41 and the power generation engine 42 in the case of using the LNG as the next propellant fuel, the container carrier 1 according to the embodiment of the present invention may have a separate design Since the GVU installation space 441 and the GVT installation space 442, which are empty spaces, can be installed without requiring any modification, the drying period is drastically reduced and the drying cost is significantly reduced. have. At this time, the propulsion engine 41 may be an engine of Wartsila, and the GVT installation space 442 may be provided as an empty space at a position within about 10 m from the propulsion engine 41.

In the embodiment of the present invention, in order to allow the propulsion engine 41 and the power generation engine 42 to use the LNG as fuel when the LNG is used as the next propulsion fuel, the gas control units GVU, GVT, That is, LNG line installation spaces 444 and 445 are provided to supply a supply line (not shown) for connecting the power generation engine 41 and the power generation engine 42 to each other.

At this time, the LNG line installation spaces 444 and 445 may be provided as empty spaces below the second deck 401 as shown in FIG. 7A, or as empty spaces below the third deck 402 as shown in FIG. 7B .

However, if the propulsion engine 41 is a MAN engine, the GVT may be provided in a gas supply room (not shown, FGS room) provided with a device for supplying LNG (gas) to the propulsion engine 41 have. Accordingly, when the propulsion engine 41 is a MAN engine, the GVT installation space 442 may not be provided between the second deck 401 and the third deck 402.

A propelling engine 41 may be installed between the third deck 402 and the fourth deck 111. The propelling engine 41 may be supported by the fourth deck 111. [

The propulsion engine 41 generates power that can propel the ship 1, and generates power by using only diesel as fuel.

The propulsion engine 41 may be a MAN engine or a Wartsila engine. The propulsion engine 41 can be changed by adding a gas module (not shown) when the engine is changed to an engine (for example, a MEGI engine) using a different fuel (LNG and diesel) A gas module installation space (not shown, a first backup space) may be provided in the upper space of the propulsion engine 41 for this purpose.

When the engine is a Wartsila company, only the cylinder liner (not shown) needs to be replaced when the engine is replaced with an engine using a different fuel (LNG and diesel). Therefore, It is not necessary to provide a space for installing a gas module in the space.

The power generation engine 42 generates electric power to be supplied to the electronic devices in the ship 1, and can generate electric power using only diesel as fuel.

However, in the past, when the propulsion engine is changed to an engine using a different fuel (LNG and diesel) (for example, a MEGI engine), the power generation capacity of the power generation engine, There is a problem in that the power capacity can not be covered and must be replaced again. In this case, since the side surface of the hull 1 must be completely exposed to replace the power generation engine, the drying period is increased and the drying cost is increased.

Therefore, in the embodiment of the present invention, even if the propulsion engine 41 is changed to an engine (a MEGI engine) using different types of fuel (LNG and diesel) so as to use LNG as the propellant fuel of the next container carrier 1, (X-DF engine) using a different kind of fuel (LNG and diesel) in advance in order to prevent the engine 42 from being replaced.

At this time, the power generation engine 42 using the heterogeneous fuel (LNG and diesel) has a capacity enough to cover the power generation capacity required by the propulsion engine (MEGI engine) using the dissimilar fuel (LNG and diesel).

Alternatively, the power generation engine 42 may be replaced by an engine using a different kind of fuel (LNG and diesel) (X-DF engine) It can be designed to cover the power generation capacity required by the propulsion engine (MEGI engine) used. In this case, the construction cost is lower than that of the power generation engine 42 using different kinds of fuel (LNG and diesel). However, in terms of space securing, the power generation engine 42 using the different fuel (LNG and diesel) There is an advantage.

Therefore, in the embodiment of the present invention, the power generation engine 42 is installed on the ship 1 as an engine (X-DF engine) using different kinds of fuel (LNG and diesel) Since the side of the hull 1 can be dried without being exposed even if the propulsion engine 41 is changed to an engine (a MEGI engine) using a different kind of fuel (LNG and diesel) in order to use the LNG as fuel, And the drying cost is also remarkably reduced.

In the case of an engine (X-DF engine) using different kinds of fuel (LNG and diesel), the power generation engine 42 includes a diesel fuel injection nozzle mounting portion (not shown) and an LNG fuel injection nozzle mounting portion And a stroke unit 422 having a cylinder S and a piston P, as shown in FIG.

The diesel fuel injection nozzle mounting portion includes an oil component use nozzle 4211 (diesel fuel injection nozzle), and the oil component use nozzle 4211 can inject diesel fuel to the power generation engine 42. [

The LNG fuel injection nozzle mounting portion includes an LNG fuel use nozzle 4212 (LNG fuel injection nozzle), and the LNG fuel use nozzle 4212 can inject LNG fuel to the power generation engine 42, .

Therefore, in the embodiment of the present invention, the power generation engine 42 is installed in the ship 1 by an engine (X-DF engine) using different kinds of fuel (LNG and diesel) in advance, and the LNG distribution nozzle is formed as a dummy member Even if the propulsion engine 41 is changed to an engine (a MEGI engine) using a different kind of fuel (LNG and diesel) so as to use LNG as propellant fuel for the next container carrier 1, It can be dried without being exposed, so that the drying period is drastically reduced and the drying cost is also remarkably reduced.

The boiler 43 generates heat to convert water to steam and can convert water to steam using only diesel fuel or using a different fuel (LNG and diesel).

The engine control room 45 is disposed between the containers C stacked on the second deck 401 to receive an engine controller (not shown) for controlling the propulsion engine 41 or the power generation engine 42 .

The engine control room 45 is connected to the propulsion engine 41 or the power generation engine 42 to enable the propulsion engine 41 or the power generation engine 42 to use the LNG as fuel when the LNG is used as the next propulsion fuel. An LNG control switch board installation space 443 for installing a gas supply controller (not shown) for controlling the supply of LNG fuel to the LNG supply line (not shown)

At this time, in the embodiment of the present invention, the gas supply controller and the propulsion engine 41 are controlled so that the propulsion engine 41 or the power generation engine 42 uses the LNG as the fuel when the LNG is used as the next propulsion fuel. Or a power line installation space 446 for installing a power line (not shown) connecting the power generation engine 42 to the second deck 401 as an empty space. (See Fig. 7C)

As described above, in the embodiment of the present invention, in order to use the LNG as the fuel for the propulsion engine 41 and the power generation engine 42 in the case of using LNG as the next propelling fuel, Since the gas supply controller and the power line can be installed directly in the LNG control switchboard installation space 443 and the power line installation space 446 as the empty space, the drying period is drastically reduced and the drying cost is significantly reduced.

The cargo hold 50 is formed so that the bays in which the containers C are stacked are bundled into two units (that is, two bays are provided in one cargo hold 50) .

Specifically, the cargo hold 50 is provided with an open BHD structure between the two watertight transverse bulkhead structures (front BHD structures) provided on both front and rear sides to form a first bail 51 and a second bail 52 can be partitioned.

The watertight transverse bulkhead structure refers to a structure in which one side is closed and the other side is open, and the open transverse bulkhead structure is a structure in which one side and the other side are both open.

Specifically, the watertight transverse bulkhead structure is a structure that connects one or two or more unit bulkheads with each other by a vertical or horizontal member. One of the unit bulkheads is a watertight bulkhead or a closed bulkhead. The other unit bulkhead is composed of an open bulkhead or a structural bulkhead. Here, the vertical member may be a longitudinal bulkhead or a vertical web, and the horizontal member may serve as a deck.

The first and second transverse bulkhead structures 63 and 64 may include openings 631 and 641 that open at one side and closures 632 and 642 at which the other side is closed, The sealing portions 632 and 642 may be provided outside the sealing portions 632 and 642 from the inside of the bay 60. The sealing portions 632 and 642 may include heat insulating layers 633 and 643 for insulating the bay 60. [ Here, the heat insulating layers 633 and 643 may be formed of A-60.

The first and second transverse bulkhead structures 63 and 64 securely receive the liquefied gas storage tank T to be dried in the bay 60 for retrofit of the subsequent container carrier 1, (The propulsion engine 41, the power generation engine 42, the boiler 43, etc.) accommodated in the engine room 40 or the containers C accommodated in the cargo hold 50 Equipment or safety measures shall be provided in advance.

To this end, in the embodiment of the present invention, the first and second transverse bulkhead structures 63 and 64 are all formed of a watertight transverse bulkhead structure, and the heat insulating layers 633 and 634 are additionally constituted.

The first and second transverse barrier rib structures 63 and 64 are formed by connecting one or two or more unit barrier ribs 631, 632, 641 and 642 with the unit barrier ribs 631, 632, 641 and 642 through vertical or horizontal members It is possible structure. One of the unit bulkheads 631, 632, 641 and 642 is a watertight bulkhead or a closed bulkhead 632,642 and the other is an open bulkhead or a structural bulkhead 631 or 641.

The vertical member may be a longitudinal bulkhead or a vertical web, and the horizontal member may serve as a deck

The first transverse bulkhead structure 63 may have an opening 631 that opens to the engine room 40 side and a closed portion 632 that is closed to the inside of the bay 60. The second transverse bulkhead structure 64 may have an opening portion 641 that is opened toward the cargo hold 50 side and a closing portion 642 that is formed to be hermetically sealed inside the bay 60.
