Accordingly, since the adhesion between the manhole 31 and the deck part 1 is improved and the sealing property is improved, the effect that seawater does not penetrate into the hull can be expected.

이상에서 설명한 바와같이 본 발명은 선체 내부에 주연료탱크와 부연료탱크를 각각 형성하고, 상기 주연료탱크와 부연료탱크를 연결파이프로서 연결하되, 연결파이프상에 밸브를 형성하고, 상기 밸브개폐용 조절레버를 데크부 상부에 노출되게 설치하며, 맨홀의 상단부에 별도의 플랜지를 형성하여 데크부에 이중결합하도록 구성하므로서, 맨홀 결합부위의 밀폐율 및 내구성이 향상되도록 하여 해수 유입을 차단하고, 부연료탱크에 저장된 보조연료를 이용하여 장거리 항해가 가능하도록 함은 물론 부연료탱크에 저장된 연료를 주연료탱크로 공급하는 조절레버를 데크부 상측에 노출되게 형성하여 조작성이 향상되도록 한 고속단정의 연료탱크장치를 제공하는 효과를 기대할 수 있다.As described above, the present invention forms a main fuel tank and a sub-fuel tank in the hull, respectively, and connects the main fuel tank and the sub-fuel tank as a connection pipe, and forms a valve on the connection pipe, and opens and closes the valve. The control lever is installed to be exposed to the upper part of the deck, and by forming a separate flange at the upper end of the manhole to configure a double coupling to the deck, to block the inflow of seawater by improving the sealing rate and durability of the manhole coupling, The high-speed endurance design enables not only long distance navigation by using auxiliary fuel stored in the sub-fuel tank, but also the control lever for supplying fuel stored in the sub-fuel tank to the main fuel tank to be exposed to the upper side of the deck for improved operability. The effect of providing a fuel tank device can be expected.
