Generally, a ship is driven by an engine that generates power by the combustion of fuel. The diesel, heavy oil, MOD (Marine Diesel Oil), and MFO (Marine Fuel Oil) It is a cause of environmental pollution due to a large amount of harmful substances generated.

이러한 이유로 인해 친환경 선박(Green-ship)으로 액화천연가스(Liquefied Natural Gas, 이하 "LNG"라 함)를 연료로 사용하는 선박(LNG Fueled Ship, 이하 "LFS"라 함)이 개발되어, 각국의 선급으로부터 공식인증(Approval In Principle, AIP)을 승인받아 환경규제로 인한 청정에너지로의 전환 요구를 충족시키고 있다.For this reason, LNG Fueled Ship (hereinafter referred to as "LFS") which uses Liquefied Natural Gas (hereinafter referred to as "LNG") as an eco-friendly ship has been developed, Approval of the Approval In Principle (AIP) from the Society has been made to meet the requirement to convert to clean energy due to environmental regulations.

종래의 LNG를 연료로 사용하는 선박에 대한 기술로는 한국공개특허 제10-2012-0123398호의 듀얼 연료시스템이 마련된 액화석유가스 운반선이 있다. 이는 디젤유와 액화석유가스를 연료로 동력을 제공하는 선박 추진용 엔진이 탑재된 액화석유가스 운반선에 있어서, 갑판에 설치되며 액화석유가스가 저장되는 데크 탱크; 상기 데크 탱크와 선박 추진용 엔진을 연결하여 상기 데크 탱크에 저장된 액화석유가스를 선박 추진용 엔진으로 공급하는 유로가 형성된 제 1 연료이송배관; 상기 제 1 연료이송배관에 설치되어 데크 탱크에 저장된 액화석유가스를 선박 추진용 엔진으로 고압의 상태로 이송시키는 제 1 연료이송용 고압펌프; 상기 제 1 연료이송용 고압펌프를 통해 선박 추진용 엔진으로 공급되는 액화석유가스를 단속하는 제 1 연료이송배관에 설치되는 제 1 차단밸브; 및 상기 제 1 연료이송배관에 설치되어 선박 추진용 엔진으로 공급되는 액화석유가스가 선박 추진용 엔진에서 연소되기 적당한 온도로 공급될 수 있게 상기 액화석유가스를 승온시키는 히터;를 포함한다.As a technique for a ship using conventional LNG as a fuel, there is a liquefied petroleum gas carrier provided with a dual fuel system of Korean Patent Laid-Open No. 10-2012-0123398. This is a liquefied petroleum gas carrier equipped with a propulsion engine for powering diesel oil and liquefied petroleum gas, comprising: a deck tank installed on a deck and storing liquefied petroleum gas; A first fuel delivery pipe connected to the deck tank and the ship propulsion engine to form a flow path for supplying liquefied petroleum gas stored in the deck tank to the ship propulsion engine; A first high pressure pump for transferring the liquefied petroleum gas stored in the deck tank to the ship propulsion engine at a high pressure; A first shut-off valve installed in a first fuel transfer pipe for interrupting liquefied petroleum gas supplied to the ship propulsion engine through the first fuel transfer high-pressure pump; And a heater installed in the first fuel transfer pipe for heating the liquefied petroleum gas so that the liquefied petroleum gas supplied to the ship propulsion engine can be supplied at a temperature suitable for combustion in the ship propulsion engine.

이러한 종래의 LNG 운반선은 데크 탱크, 즉 연료탱크가 어퍼데크(Upper deck) 상측에 설치되는데, 이와 같이 선박의 연료탱크가 어퍼데크 상에 설치되는 구조를 설명하면 다음과 같다.In this conventional LNG carrier, a deck tank, that is, a fuel tank is installed on the upper deck, and a structure in which the fuel tank of the ship is installed on the upper deck will be described as follows.

도 1은 종래의 기술에 따른 선박의 연료탱크 설치구조를 도시한 정면도이다.1 is a front view showing a fuel tank installation structure of a ship according to a conventional technique.

도 1에 도시된 바와 같이, 종래의 기술에 따른 선박의 연료탱크 설치구조(1)는 어퍼데크(2)의 상부에 연료탱크(3)의 하부를 지지하는 지지대(4)가 설치됨으로써 지지대(4)에 의해 연료탱크(3)가 어퍼데크(2)로부터 상방으로 이격되도록 설치된다. 연료탱크(3)에는 LNG가 저장되어, 추진용 엔진 등을 비롯하여 연료 소요처에 연료로서 공급된다.1, in a fuel tank installation structure 1 of a conventional technique, a support 4 for supporting a lower portion of a fuel tank 3 is provided on an upper deck 2, 4 so that the fuel tank 3 is spaced upward from the upper deck 2.

Therefore, it is difficult to secure the visibility line L in the deck house 5 when the size of the fuel tank 3 is large, and the height of the deck house 5 must be increased in order to secure the sight line L. . Also, as the fuel tank 3 placed on the upper deck 2 is larger, the weight of the upper deck 2 is increased and the center of gravity is increased. Therefore, the ship is required to be reinforced and vulnerable to rolling In addition, there was a problem that the stability of the hull was deteriorated.

고정부(120)는 연료탱크(20)에 단일로 설치되거나, 연료탱크(20)의 길이방향을 따라 간격을 두고서 다수개가 나란하도록 설치될 수 있으며, 보강재(130)에 의해 구조적으로 보강될 수 있다. The fixing portions 120 may be installed in the fuel tank 20 in a single manner or may be arranged such that a plurality of the fuel injectors 120 are spaced apart along the longitudinal direction of the fuel tank 20 and may be structurally reinforced by the stiffener 130 have.

보강재(130)는 예컨대 고정부(120)에 동심원을 이루도록 용접이나 볼트 또는 브라켓 등으로 부착될 수 있고, 링 형태의 고정부(120)와 동심원을 이루기 위하여 링 형태로 이루어질 수 있다. 또한 보강재(130)는 고정부(120)에서 일측면에만 부착되거나, 양측면에 부착될 수 있고, 상부보강재(131)와 하부보강재(132)로 분할된 구조로 이루어짐으로써 어퍼데크(10)의 상측과 하측에 각각 용접이나 볼트 등으로 고정될 수 있다. 이와는 다른 예로서 보강재(130)는 단일 링 형태로 이루어짐으로써 고정부(120)에 부착될 수도 있다.The stiffener 130 may be attached to the fixing portion 120 by welding, bolt, or bracket so as to be concentric with the fixing portion 120, and may be formed in a ring shape to be concentric with the fixing portion 120 of the ring shape. The stiffener 130 may be attached to only one side of the fixing part 120 or may be attached to both sides of the fixing part 130 and may be divided into an upper stiffener 131 and a lower stiffener 132, And may be fixed to the lower side by welding or bolt, respectively. As another example, the stiffener 130 may be attached to the fixing portion 120 by being formed in a single ring shape.

이와 같은 본 발명에 따른 선박의 연료탱크 설치구조에 따르면, 연료탱크(20)가 어퍼데크(10)에 설치됨에도 불구하고, 연료탱크(20)가 어퍼데크(10)에 관통하여 수용됨으로써 연료탱크(20)의 높이를 낮출 수 있도록 하며, 이로 인해 연료탱크(20)가 데크하우스(Deckhouse)의 전방에 인접하여 설치되더라도 데크하우스로부터의 가시선(Visibility line) 확보가 충분하게 이루어지도록 하고, 이로 인해 데크하우스의 증축을 필요로 하지 않는다.According to the fuel tank installation structure of the present invention, even though the fuel tank 20 is installed on the upper deck 10, the fuel tank 20 is received through the upper deck 10, So that the height of the fuel tank 20 can be lowered. Thus, even if the fuel tank 20 is installed adjacent to the front of the deckhouse, sufficient visibility lines can be ensured from the deckhouse, No deckhouse needs to be added.

또한 연료탱크(20)의 높이 감소로 인해 어퍼데크(20) 상부 구조물의 중량을 절감하여 무게중심을 낮추어서 롤링(Rolling)에 대한 선체의 안정성을 증가시키고, 링형태의 고정부(120)와 보강재(130) 등의 연료탱크(20) 고정 구조로 인해 연료탱크(20)의 안정적인 고정을 가능하도록 할 뿐만 아니라, 연료탱크(20)의 하부 보강을 줄일 수 있도록 한다.Also, since the height of the fuel tank 20 is reduced, the weight of the upper structure of the upper deck 20 is reduced to lower the center of gravity, thereby increasing the stability of the hull against rolling, The fuel tank 20 can be stably fixed due to the fixing structure of the fuel tank 20 such as the fuel tank 130 and the lower reinforcement of the fuel tank 20 can be reduced.

본 발명은 상기 실시례에 한정되지 않고, 본 발명의 기술적 요지를 벗어나지 아니하는 범위 내에서 다양하게 수정 또는 변형되어 실시될 수 있음은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 있어서 자명한 것이다.It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. It is.
