상기 재기화부(122)는 상기 LNG저장탱크(121)로부터 공급되는 액화천연가스(LNG)를 재기화시키기 위한 것이다. 상기 재기화부(122)는 관 또는 파이프와 같은 천연가스관로를 통해 상기 LNG저장탱크(121)에 연결될 수 있다. 이에 따라, 상기 재기화부(122)는 상기 LNG저장탱크(121)로부터 액화천연가스(LNG)를 공급받을 수 있다. 상기 재기화부(122)는 관 또는 파이프와 같은 해수관로를 통해 외부에 위치하는 해수에 연결될 수 있다. 상기 해수관로에는 해수를 이동시키기 위한 이송력을 제공하는 펌프가 설치될 수 있다. 이에 따라, 상기 재기화부(122)는 해수를 공급받을 수 있다. 상기 재기화부(122)는 상기 LNG저장탱크(121)로부터 공급받은 액화천연가스(LNG) 및 해수를 열교환시킴으로써, 액화천연가스(LNG)를 재기화시킬 수 있다. 상기 LNG저장탱크(121)에 저장된 액화천연가스(LNG)의 온도는 영하 165 ℃이므로, 액화천연가스(LNG)는 영하 165 ℃를 초과하는 온도를 가진 해수에 의해 용이하게 천연가스(NG)로 재기화될 수 있다. 따라서, 상기 해수는 액화천연가스(LNG)를 재기화시키기 위한 가열매체가 될 수 있다. 상기 재기화부(122)는 상기 가열매체로 해수를 사용할 수 있으나, 이에 한정되지 않으며 상기 액화천연가스(LNG)를 재기화시킬 수 있으면 다른 유체를 가열매체로 사용할 수도 있다. 예컨대, 상기 재기화부(122)는 상기 부유식 발전설비(14)에서 배출되는 유체를 공급받아 액화천연가스(LNG)를 재기화시킬 수 있다. 이 경우, 상기 부유식 발전설비(14)에서 배출되는 유체는 영하 165 ℃를 초과하는 온도를 가질 수 있다. 상기 재기화부(122)에서 재기화된 천연가스(NG)는 관로를 통해 상기 접안설비(13)로 공급될 수 있다. 상기 재기화부(122)는 상기 해수와 상기 액화천연가스(LNG)를 직접 열교환시키는 해수직접열교환방식, 및 글리콜, 청구, 프로판 등의 중간열교환매체를 통해 상기 해수와 상기 액화천연가스(LNG)를 열교환시키는 해수간접열교환방식 중 적어도 하나를 이용하여 상기 액화천연가스(LNG)를 기화시킬 수도 있다. 상기 해수직접열교환방식은 해수를 이용하여 액화천연가스(LNG)를 직접 기화시키므로 운용비용이 저렴한 장점이 있으나, 해수 온도에 민감하게 반응하는 단점이 있다. 상기 해수간접열교환방식은 중간열교환매체를 이용하여 액화천연가스(LNG)를 간접 기화시키므로 해수의 온도 변화에 덜 민감하게 반응할 수 있을 뿐만 아니라, 해수에 포함된 염분을 제거할 필요가 없다. 또한, 상기 해수간접열교환방식은 상기 해수직접열교환방식에 비해 액화천연가스(LNG)를 기화시키는데 필요한 해수의 양이 적으므로, 상기 해수직접열교환방식에 비해 해수관로의 크기를 줄일 수 있을 뿐만 아니라 해수관로가 부식되는 정도가 덜하다. 따라서, 상기 해수간접열교환방식은 상기 해수직접열교환방식에 비해 구축비용이 저렴한 장점이 있다.The regasification unit 122 is for regasifying the liquefied natural gas (LNG) supplied from the LNG storage tank 121. The regasification unit 122 may be connected to the LNG storage tank 121 through a natural gas pipeline such as a pipe or a pipe. Accordingly, the regasification unit 122 may receive the liquefied natural gas (LNG) from the LNG storage tank 121. The regasification unit 122 may be connected to seawater located outside through a seawater pipe such as a pipe or a pipe. The seawater pipe may be provided with a pump providing a transfer force for moving the seawater. Accordingly, the regasification unit 122 may be supplied with seawater. The regasification unit 122 may regasify the liquefied natural gas (LNG) by heat-exchanging the liquefied natural gas (LNG) and sea water supplied from the LNG storage tank 121. The temperature of the liquefied natural gas (LNG) stored in the LNG storage tank 121 is minus 165 ℃, liquefied natural gas (LNG) is easily converted to natural gas (NG) by sea water having a temperature exceeding 165 ℃ Can be regasified. Therefore, the seawater may be a heating medium for regasifying the liquefied natural gas (LNG). The regasification unit 122 may use seawater as the heating medium. However, the regasification unit 122 is not limited thereto. If the liquefied natural gas (LNG) is regasified, another fluid may be used as the heating medium. For example, the regasification unit 122 may regasify the liquefied natural gas (LNG) by receiving the fluid discharged from the floating power generation facility 14. In this case, the fluid discharged from the floating power generation facility 14 may have a temperature exceeding minus 165 ℃. The natural gas NG regasified by the regasification unit 122 may be supplied to the eyepiece 13 through a pipeline. The regasification unit 122 is a seawater direct heat exchange method for directly heat-exchanging the seawater and the liquefied natural gas (LNG), and the seawater and the liquefied natural gas (LNG) through an intermediate heat exchange medium such as glycol, billing, propane, etc. The liquefied natural gas (LNG) may be vaporized using at least one of the seawater indirect heat exchange method. The seawater direct heat exchange method directly vaporizes liquefied natural gas (LNG) using seawater, which has the advantage of low operating cost, but has a disadvantage in that it is sensitive to seawater temperature. The seawater indirect heat exchange method indirectly vaporizes liquefied natural gas (LNG) using an intermediate heat exchange medium, so that it is less sensitive to changes in seawater temperature and does not need to remove salts contained in seawater. In addition, since the seawater indirect heat exchange method has a smaller amount of seawater required to vaporize liquefied natural gas (LNG) than the seawater direct heat exchange method, it is possible to reduce the size of the seawater pipe as well as the seawater pipe compared to the seawater direct heat exchange method. Less corrosive to the pipeline. Therefore, the seawater indirect heat exchange method has an advantage of low construction cost compared to the seawater direct heat exchange method.

셋째, 본 발명의 제2실시예에 따른 해상발전시스템(21)은 복수개의 발전기를 이용하여 전기를 생산하도록 구현됨으로써, 전기 생산량을 증대시킬 수 있을 뿐만 아니라 정전과 같은 비상 시 상기 실시예들에 비해 신속하게 전기를 생산할 수 있다. 또한, 본 발명의 제2실시예에 따른 해상발전시스템(21)은 육상의 사용처로 공급하기 위한 전기 생산이 중단되는 것을 방지할 수 있다.Third, the marine power generation system 21 according to the second embodiment of the present invention is implemented to produce electricity by using a plurality of generators, thereby not only increasing the amount of electricity produced but also in the above-described embodiments in case of an emergency such as a power failure. It can produce electricity faster than that. In addition, the marine power generation system 21 according to the second embodiment of the present invention can prevent the generation of electricity for supply to the land use.
넷째, 본 발명의 제2실시예에 따른 해상발전시스템(21)은 상기 천연가스(NG)가 상기 이종연료엔진(24111) 및 상기 가스터빈(24121)으로 분기되는 부분에 밸브를 설치함으로써, 상기 이종연료엔진(24111) 및 상기 가스터빈(24121)으로 공급되는 천연가스(NG)의 양을 조절할 수 있다. 이에 따라, 본 발명의 제2실시예에 따른 해상발전시스템(21)은 상기 제1발전기(24112), 상기 제2발전기(24122) 및 상기 제3발전기(24125)가 각각 생산하는 전기의 양을 조절할 수 있다.Fourth, in the offshore power generation system 21 according to the second embodiment of the present invention, by installing a valve at a portion where the natural gas NG branches to the heterogeneous fuel engine 24111 and the gas turbine 24121, The amount of natural gas NG supplied to the heterogeneous fuel engine 24111 and the gas turbine 24121 may be adjusted.

And, it may further comprise a seawater flow rate sensor for measuring the seawater flow rate inside the seawater pipe. The seawater valve is for adjusting the degree of opening of the seawater pipe to adjust the amount of seawater supplied to the regasification unit 222. The seawater valve may be controlled by the seawater flow rate controller to adjust the degree of opening of the seawater pipe. The seawater flow rate control unit may be connected to the seawater flow rate sensor by at least one of wireless communication and wired communication, so that the seawater flow rate sensor may receive information about the seawater flow rate inside the seawater pipe from the seawater flow rate sensor. The seawater flow rate control unit may control the seawater valve so that the opening degree of the seawater pipe is reduced when the seawater flow rate measured by the seawater flow rate measurement sensor exceeds a preset reference seawater flow rate. In this case, the flow rate of seawater supplied from the intake unit 221 to the regasification unit 222 may be reduced. The seawater flow rate control unit may control the seawater valve so that the opening degree of the seawater pipe is increased when the seawater flow rate measured by the seawater flow rate measurement sensor is less than a predetermined reference seawater flow rate. In this case, the flow rate of seawater supplied from the intake unit 221 to the regasification unit 222 may be increased. The reference seawater flow rate refers to the minimum seawater flow rate required to regasify the liquefied natural gas (LNG), and may be preset by an operator. When the seawater flow rate control unit does not need to supply seawater to the regasification unit 222, the seawater flow rate control unit may block the seawater supplied to the regasification unit 222 by controlling the seawater valve to close the seawater pipe. If it is not necessary to supply seawater to the regasification unit 222, the amount of seawater already supplied to the regasification unit 222 is not only sufficient to regasify the liquefied natural gas (LNG) in the regasification unit 222 In this case, the cooling system 242 is sufficient to cool at least one of the heterogeneous fuel engine 2111 and the gas turbine 24121. Accordingly, since the marine system 21 according to the second embodiment of the present invention can reduce the amount of seawater taken from the outside, it is possible to prevent waste of resources.
