Description

가스 및 전기 생산설비가 구비된 부유식 엘엔지 급유시설{Floating Storage Regasfication Power generation Bunkering}   Floating Storage Regasfication Power generation Bunkering}

본 발명은 부유식 LNG 급유시설에 관한 것으로서, 보다 상세하게는 기존의 육상 LNG 저장설비에 비해 설비 제작 기간이 짧고 육상과 같이 선박 접안을 위한 별도의 안벽/방파제와 같은 부수적인 설비가 필요 없으며, 도시 근처에 LNG 저장설비가 있을 경우 발생할 수 있는 안전문제 및 민원 문제를 해결할 수 있는 가스 및 전기 생산설비가 구비된 부유식 LNG 급유시설에 관한 것이다.The present invention relates to a floating LNG refueling facility, more specifically, a shorter production period than existing onshore LNG storage facilities, and does not require an additional facility such as a separate quay / breakwater for ship berthing, such as onshore. The present invention relates to a floating LNG refueling facility equipped with gas and electricity production facilities that can solve safety and civil complaints that may occur when there is an LNG storage facility near a city.

액화 천연 가스(LNG)는, 가스 상태에서 천연 가스의 동일한 양이 차지하는 부피의 약 1/600만을 차지하며, 액화 천연가스는 천연가스를 비등점(주위 압력에서 -259℉)이하로 냉각시켜 만든다.Liquefied natural gas (LNG) occupies only about 1/600 of the volume of the same amount of natural gas in the gas state, and liquefied natural gas is produced by cooling natural gas below its boiling point (-259 ° F. at ambient pressure).

이러한 이유로 액화 천연가스는 대기압 또는 그보다 다소 높은 압력에서 극저온 탱크에 보관된다.For this reason, liquefied natural gas is stored in cryogenic tanks at atmospheric or somewhat higher pressures.

상기 보관된 액화 천연가스는 온도를 상승시켜 다시 가스 형태로 변환시키는데, 이러한 과정을 일반적으로 액화 가스 재기화 (Regasification) 과정이라 한다.The stored liquefied natural gas is converted to a gas form by raising the temperature, which is generally referred to as a liquefied gas regasification process.

종래에는 일반적으로 육지에서 상기 액화 가스의 재기화 작업을 하였다. 액화 천연가스 운반선은 목적 항에 도착하면 육지에 기반을 둔 재기화 시설로 액화 가스를 송출하는데, 상기 액화 가스는 육상의 극 저온 저장탱크에서 액화 상태로 보관되고 필요에 따라 재기화 설비를 통하여 기화되어 육상 가스 배관망을 통하여 소비처로 이송되었다.In the past, regasification of the liquefied gas was generally carried out on land. A liquefied natural gas carrier delivers liquefied gas to a land-based regasification plant upon arrival at the destination port, which is stored liquefied in a terrestrial cryogenic storage tank and vaporized via a regasification plant as needed. It was then transferred to the consumer through the land gas pipeline.

그러나 2001년 미국에서 발생한 911테러 이후에 위험물에 대한 안전상의 요구가 크게 증가하였고, 되도록이면 위험시설을 사람이 거주하는 육지에 두지 말고 해상에서 이루어지는 형태를 추구하게 되었다.However, since the 2001 terrorist attacks in the United States in 2001, the demand for safety of dangerous goods has increased significantly, and as much as possible, they have pursued a form of maritime rather than placing dangerous facilities on inhabited land.

이와 같은 세계적인 추세에 따라 상기 액화 가스의 재기화 과정 역시 해상에서 이루어지는 형태가 출현하게 되었고, 부유식 천연가스 저장 및 재가스화 유닛(FSRU: Floating Storage and Regasification Unit), 부유식 해상 원유생산 및 저장설비(FPSO: Floating Production Storage Offloading)와 같은 플로터(Floater)들이 바로 그것이다.In line with this global trend, the process of regasification of the liquefied gas also takes place at sea, floating natural gas storage and regasification units (FSRUs), floating offshore oil production and storage facilities. That's what Floaters like Floating Production Storage Offloading (FPSO) do.

도 1은 종래기술의 부유식 천연가스 저장 및 재가스화 유닛을 이용한 천연가스 공급 구조도이다.1 is a natural gas supply structure using a floating natural gas storage and regasification unit of the prior art.

도 1을 참조하면, 부유식 천연가스 저장 및 재가스화 유닛(10)에 LNG선(21)이 접안하여 LNG 저장설비(11)로 LNG연료를 이송하여 저장하게 된다.Referring to FIG. 1, the LNG carrier 21 is docked in the floating natural gas storage and regasification unit 10 to transport and store LNG fuel to the LNG storage facility 11.

이후, LNG 저장설비(11)에 저장된 LNG연료는 가스 생산설비(13)로 보내져 재기화 과정을 거쳐 천연가스를 생산하게 된다.Thereafter, the LNG fuel stored in the LNG storage facility 11 is sent to the gas production facility 13 to undergo a regasification process to produce natural gas.

이때 생산된 천연가스는 해저 가스 송출관(14)을 이용해 육상의 수급처(23) 에 공급된다.At this time, the produced natural gas is supplied to the supply and demand destination 23 of the land using the subsea gas discharge pipe (14).

이와 같은 종래기술은 LNG를 재기화시켜 육상의 수급처(23)에 공급만 하는 단조로운 기능을 갖는 한계가 있었다.Such a prior art has a limit that has a monotonous function of only regasifying LNG and supplying it to the land supply and supply destination 23.

또한, 육상에 LNG 저장기지가 있는 경우, LNG 연료 추진선박이 접안하기 위한 접안설비와 LNG 연료 공급설비가 별도로 설치되어야 하기 때문에 추가적인 부두 접안 시설 및 하역시설 등을 준비해야 하고 이에 따른 막대한 비용이 소요되는 문제가 있었다.In addition, if there is an LNG storage base on land, additional docking docking facilities and unloading facilities need to be prepared because the berthing facilities and LNG fuel supply facilities for LNG fuel propulsion vessels to be docked need enormous costs. There was a problem.

현재, 진행중인 LNG 추진선박에 필요한 급유선의 경우를 보면, 본 급유선의 LNG 급유를 위해 기존 LNG 기지로 이동해야 하기 때문에 이동에 따른 추가적인 시간 및 비용이 소요되는 문제가 있었다.At present, in the case of a fuel tanker required for the ongoing LNG propulsion vessel, there was a problem that it takes additional time and cost according to the movement because it needs to move to the existing LNG base for LNG refueling of the oil tanker.

이러한 문제를 극복하기 위해, LNG 급유를 위한 중간 터미널(Terminal)을 개발하고 있으나, 이 또한 LNG 적하역 시 발생되는 증발가스(BOG)를 처리하기 위한 별도의 재기화 장비를 필요로 하는 문제가 있었다.In order to overcome this problem, we are developing an intermediate terminal for LNG refueling, but this also requires a separate regasification equipment for treating boil-off gas (BOG) generated during LNG loading and unloading. .

종래기술의 문제점을 해결하기 위해 안출된 본 발명의 목적은 기존의 육상 LNG 저장설비에 비해 설비 제작 기간이 짧고 육상과 같이 선박 접안을 위한 별도의 안벽/방파제와 같은 부수적인 설비가 필요 없으며, 도시 근처에 LNG 저장설비가 있을 경우 발생할 수 있는 안전문제 및 민원 문제를 해결할 수 있는 가스 및 전기 생산설비가 구비된 부유식 LNG 급유시설을 제공함에 있다.The object of the present invention devised to solve the problems of the prior art is shorter production period compared to the existing land LNG storage facilities, and does not require additional equipment such as a separate quay / breakwater for ship docking, such as onshore, It is to provide a floating LNG refueling facility equipped with gas and electricity production facilities that can solve safety and civil complaints that may occur when there is an LNG storage facility nearby.

Will be supplied to the facility.

또한, LNG 저장설비(110)에 저장된 LNG연료는 가스 생산설비(131)로 보내져 재기화 과정을 거쳐 천연가스를 생산하게 된다. 이때, 생산된 천연가스는 해저 가스 송출관(141)을 이용해 육상의 시설에 공급하게 된다. 이때 생산된 가스는 전기 생산설비의 연료로 사용할 수 있다.In addition, the LNG fuel stored in the LNG storage facility 110 is sent to the gas production facility 131 to produce natural gas through a regasification process. At this time, the produced natural gas is supplied to a facility on land using the subsea gas discharge pipe 141. The gas produced at this time can be used as a fuel for electricity production equipment.
