Description

TECHNICAL FIELD [0001] The present invention relates to a method for optimally arranging a fuel tank for a gas fuel in a container ship using an open type bulkhead,

The present invention relates to a method of optimally arranging a container fuel tank for a gaseous fuel using an open type bulkhead and a ship to which the present invention is applied. More particularly, 5 (line width division 5)) is used as a fuel tank for gaseous fuel, and a part of the bulkhead is opened and the fuel tank room is expanded by 20ft container length in the central cargo hold, so that the required gaseous fuel can be sufficiently loaded Space is secured. The present invention also relates to a method for optimally arranging a container fuel tank having a liquid fuel tank on the outside of a gas fuel tank and a ship to which the method is applied.

Generally, a propulsion engine using heavy oil (HFO) (or MDO) such as bunker C oil is used for a commercial vessel such as a container. However, recently, the fuel supply system using liquefied fuel (LNG, LPG, CNG, DME), which is much cheaper than heavy fuel oil due to the rise in oil prices, is attracting attention.

Accordingly, as a fuel oil of various ships, clean fuel such as LNG (or LPG, CNG, DME), which is gaseous fuel in liquefied or gaseous state, is used instead of or in the case of not using heavy oil (MDO) have.

In addition, there are generally membrane type, independent type B and independent type C type in which the liquefied gas fuel can be loaded.

In case of membrane type, GTT company which has original technology is provided with enormous royalty and is used. However, due to the partial movement of the fluid, the relative movement between the fluid and the container holding the fluid, that is, the sloshing phenomenon occurs, and the structure can be destroyed by impacting the container. Also, in the case of the independent type C, there is a problem that the loading efficiency of the container is poor because it must be manufactured in the form of a sphere or a cylinder.

Normally, a large container ship of 10,000 teu class or above is placed at the center of the deck house to secure the seashore.

Due to the cabin space located above the upper deck of the container line, it is not possible to load the container in the lower space, which is normally used as a liquid fuel storage tank.

However, in order to guarantee the same cruising range due to the limitation of fuel tank arrangement according to the IGF CODE (international regulations on the drying and installation of acidic liquefied gas carrier) and the difference in calorific value between liquid fuel and gaseous fuel, This results in a reduction of container loading space.

As a prior art of the above technique for solving such a problem, Korean Patent 10-2009-0098988 (container line having fuel tank for gaseous fuel) applying independent type B type has been filed.

However, the biggest problem of the patent is that it collides directly with the IGF CODE, which is planned to be enacted. Depending on the IGF CODEDP, the shape of the fuel tank should be further reduced since the fuel tank must be located within 5 / B of the side.

Also, using half of the middle cargo holds with the highest container loading efficiency as a fuel tank results in a very low loading efficiency.

The use of an excessively large number of independent fuel tanks has the problem of increasing the drying cost and the drying period, and also the width and length of the gas fuel tank are narrow and relatively high. This is because the center of gravity of the fuel tank is high, so that it is largely influenced by the wave load depending on the wave, but the support structure for supporting it is not used.

The independent type B is an independent tank type in the form of a storage tank of a liquefied gas carrier. The independent tank type is a type in which the storage tank is not integrated with the hull but the independent support tank is supported by the supporting device of the hull. It can be classified into Type A, B, and C depending on the number of installed barriers and pressure to prevent leakage of liquefied gas. . Among them, Type B is a structure to prepare leakage of primary barrier by installing a drip tray, which is a storage space other than the primary barrier, and there is a morph type of tank type and SPB type of square type IHI.

In order to solve these conventional problems, the present invention makes it possible to use the liquid fuel and the gaseous fuel together, and it is possible to use B / 5 (Breath (line width) / 5 (Line width division 5)) is used as a gas fuel tank except for the outer wall, and a portion of the bulkhead is opened and the fuel tank room is expanded by 20ft container length in the middle hold, . And installing the FGS ROOM between the lower deckhouse and the fuel tank space within the range of existing liquid fuel tanks

According to an aspect of the present invention, there is provided a container for a container, comprising: a container for accommodating a plurality of containers; a fuel tank for a stand-alone type of gaseous fuel storing a gaseous fuel, And a liquid fuel fuel tank for storing the liquid fuel.

The FGS ROOM, which is disposed in an upper portion of the fuel tank for gas fuel and a lower portion of the deckhouse, for supplying fuel to the engine, and a space other than the fuel tank for gas fuel at the rear portion of the fuel tank for liquid fuel, And to make it available as a loading area.

The independent tank is an IMO TYPE B tank. The fuel tank is located in a lower deckhouse and a pre-existing deckhouse. A portion of the bulkhead except for both side spaces is opened. And a loading space.

Further, the container is applicable except for the space where the fuel tank is disposed in the lower part of the existing deckhouse, and the fuel tank for the independent gas fuel and the fuel tank for the independent liquid fuel are constituted so as to be easy to manufacture and mount, respectively .

Further, a water purifying partition or a watertight partition may be provided at the center of the interior of the fuel tank for independent fuel gas to prevent the sloshing phenomenon.

A first step of fabricating a fuel tank for a gaseous fuel, which is constituted by a single unit in the method for optimally arranging a fuel tank for container gas using the above-described open type partition wall and which forms a watertight bulkhead and a watertight bulkhead, if necessary, The single-walled fuel tank for the liquid fuel is opened by opening the lower stern bulkhead at the position where the deckhouse is engaged during the shipbuilding operation of the ship, thereby securing a space for disposing the fuel tank for the gas fuel by providing the water- And a second step.

Also, the gas tank for fuel gasses is arranged at a space of B / 5 from the side of the ship and secured in the second step, and the other space beside the tank is used as a fuel tank for the existing liquid fuel. Step and

And a fourth step of loading the container in a space generated by a difference in size from the liquid fuel fuel tank at the rear of the fuel tank for gas fuel.

And a method of mounting the fuel tank for a gaseous fuel in a bow direction by using the arrangement method for the ship.

According to the present invention as described above, it is possible to maximize the efficiency of the operation because the container can be loaded except for the space behind the existing fuel tank and half of the center hold, where the fuel tank is disposed.

In addition, since the fuel tank to be disposed must be partially filled in consideration of the operation, watertight bulkheads can be installed at the center to reduce the sloshing phenomenon and improve the operability in the operation, and if necessary, Can be installed.

Since it is a single fuel tank, it is easy to manufacture and mount, and the width and length can be sufficiently secured as compared with the height of the tank itself, so that it is easy to support independent tanks against external waves

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side cross-sectional view of a fuel tank optimal placement method for a container gas fuel using an open type partition according to an embodiment of the present invention and a ship to which the fuel tank is arranged.

As shown in FIG. 1, the floating structure having a heterogeneous fuel propulsion system includes a plurality of fuel tanks 20 for storing fuel inside the hull 10.

A method of optimally arranging a fuel tank for a container gas fuel using an open type partition wall including a plurality of fuel tanks (20) and a ship to which the method is applied is a container line capable of transporting a plurality of containers, (21) for storing a gaseous fuel for use as a fuel and a liquid fuel tank (21) for storing a liquid fuel for use as a fuel, each of which is provided outside the gaseous fuel tank (21) (22).

The gas fuel tank 21 and the liquid fuel fuel tank 22 are installed below the deck house 30 disposed above the upper deck of the container line and in the center space of the lower space, (21), and includes liquid fuel tanks (22) on both sides.

The independent tank is an independent tank B tank. A part of the partition wall except the both side spaces is opened in the lower portion of the existing cabin space, and the fuel tank 20 is expanded by a predetermined length of the central cargo hold, .

The independent type B is an independent tank type in the form of a storage tank of a liquefied gas carrier. The independent tank type is a type in which the storage tank is not integrated with the hull but the independent support tank is supported by the supporting device of the hull. It can be classified into Type A, B, and C depending on the number of installed barriers and pressure to prevent leakage of liquefied gas. . Type B has a primary barrier and a drip tray as a separate liquefied gas storage space to prepare for leakage of the primary barrier. The tank has a spherical morphology and a rectangular IHI SPB. So that it is not restricted by the type.

Further, half of the lower portion of the existing deck house 30 allows the container to be loaded except for the space in which the fuel tank 20 is disposed, and the structure of the fuel tank 20 is formed in a single structure, And watertight partition walls or re-water partition walls are provided at the center to prevent sloshing if necessary.

The floating structure described in the present specification is a concept including all kinds of vessels such as bulk cargo ships, container ships, passenger ships, etc., and maritime plants such as oil FPSO that are used while being moored at one point of the sea in normal times.

As shown in the figure, in addition to the fuel tank 20, when the floating structure is a bulk water line, a liquid cargo carrier, or the like, one or more storage tanks capable of storing the cargo can be included. It should be noted that the storage tank may also be used as a fuel, but in this case it is treated as a cargo, not a fuel, and thus is different from the fuel stored in the fuel tank 20 in this specification .

According to the present embodiment, in some of the fuel tanks, liquid fuel such as heavy oil (HFO) or diesel oil (MDO) widely used as fuel of a propulsion device can be stored, and in the fuel tank for the remaining fuel tanks, LPG. LNG. DME. CNG or the like can be stored.

The expression liquid fuel and gaseous fuel as used herein is determined depending on whether the state when supplied to the propulsion device, that is, the engine, is liquid or gas. That is, fuel such as heavy oil or diesel oil that maintains a liquid state when supplied to a propulsion device is called a liquid fuel, and when the fuel is stored in a fuel tank, it is in a liquid state or a gas state, , LPG, DME, and CNG are called gaseous fuels.

In general, it is preferable to use a fuel gas containing a hydrocarbon component such as LNG, LPG, or CNG as a fuel other than heavy oil.

LNG, or Liquefied Natural Gas, is a liquefied natural gas extracted from a gas field and mainly composed of methane. When LNG is lowered in temperature or liquefied under pressure, the volume is reduced to about 1/600, which is advantageous in terms of space efficiency. However, the boiling point is about minus 162 degrees Celsius, so it is charged in a specially insulated tank or vessel for transportation and storage, .

LPG, or Liquefied Petroleum Gas, is used to collect crude oil from crude oil or to recover heavy hydrocarbons (2 or more carbon atoms) from crude oil or relatively heavy hydrocarbons (6 To 7 kg / hr), followed by cooling and liquefaction. The volume is reduced to approximately 1/250 during liquefaction, which is convenient for storage and transportation. Its main constituents are propane and butane, and may contain small amounts of ethane, propylene, butylene, and the like.

CNG, or Compressed Natural Gas, is compressed to about 200 atmospheres to use natural gas as fuel.

DME, or dimethyl ether (DME), is a kind of ether. It is less flammable than LPG and is non-toxic and has a high oxygen content.

Each fuel tank contains an appropriate level of insulation and sealing system depending on the type of fuel to be accommodated. Particularly, a fuel tank for containing liquefied gas such as LNG or LPG may be a membrane type or a stand-alone tank used in the field of liquefied gas storage tanks.

Will be described in detail with reference to FIG. 2, FIG. 3, and FIG.

The part of the bulkhead is opened and the fuel tank room is extended by a certain length of the central cargo hold. A space can be secured.

The B / 5 space is Breath (line width) / line width division 5, which specifies that it is applied in various ways depending on the characteristics and size of the ship.

The portion of the existing lower space excluding the portion where the gaseous fuel tank 21 is located is used as the liquid fuel tank 22. This is because a certain amount of liquid fuel is required for a gas fuel propulsion line. In addition, if the space is insufficient, the stern engine room can be placed in a sufficient free space because the required amount is not so much.

Since the gas fuel tank 21 to be disposed must be capable of partially filling in consideration of the operation, watertight bulkheads can be installed at the center to reduce the sloshing phenomenon and improve operability in the operation. If necessary, a sweeping bulkhead may be installed in the lateral direction.
