Description

부유식 급유설비 장치{FLOAT TYPE LNG AND HFO SUPPLYING APPARATUS}[0001] FLOAT TYPE LNG AND HFO SUPPLYING APPARATUS [0002]

본 발명은 부유식 급유설비 장치에 관한 것으로, 보다 상세하게는 연료 저장탱크 및 연료 송출관을 추가적으로 구성하여 접안하는 선박에 대하여 연료를 공급 및 주유를 실시할 수 있는 부유식 급유설비 장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a floating type oil supply apparatus, and more particularly, to a floating type oil supply apparatus capable of supplying fuel and supplying oil to a ship which rides by additionally constituting a fuel storage tank and a fuel delivery pipe .

일반적으로, 액화천연가스(LNG)는 가스 상태에서 천연가스의 동일한 양이 차지하는 부피의 약 1/600만을 차지하며, 천연가스를 비등점(주위 압력에서 -160℃)이하로 냉각시켜 만든다.Generally, liquefied natural gas (LNG) accounts for about 1/600 of the volume of the same amount of natural gas in the gaseous state, and is made by cooling the natural gas below the boiling point (-160 ° C 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 slightly higher pressures.

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

종래에는 일반적으로 육지에서 상기 액화가스의 재기화 작업을 하였다. 액화 천연가스 운반선은 목적 항에 도착하면 육지에 기반을 둔 재기화 시설로 액화가스를 송출하는데, 상기 액화가스는 육상의 극 저온 저장탱크에서 액화 상태로 보관되고 필요에 따라 재기화 설비를 통하여 기화되어 육상 가스 배관망을 통하여 소비처로 이송되었다.Conventionally, the liquefied gas is generally regenerated on land. When the liquefied natural gas carrier arrives at the destination port, the liquefied gas is sent to a land-based re-gasification facility. The liquefied gas is stored in a liquefied state in a very low temperature storage tank on the land, And transported to the consumer through the land gas pipeline.

최근에는 액화천연가스를 처리하기 위한 시설물을 사람이 거주하는 육지에 두지 말고 해상에서 이루어지는 형태를 추구하고 있다.In recent years, facilities for treating liquefied natural gas have been pursued in the sea rather than on land where people reside.

즉, 액화가스의 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 addition, the re-gasification process of liquefied gas is also emerging at sea, and the floating natural gas storage and regasification unit (FSRU), floating production and storage facility (FPSO: Floating Production Storage Offloading) are the Floaters.

도 1은 종래기술에 따른 부유식 급유설비 장치를 이용한 천연가스 공급 구조도이다.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a structural view of a natural gas supply system using a floating type oil supply facility apparatus according to the prior art; FIG.

상기 부유식 급유설비 장치에 LNG선(21)이 접안하여 LNG 저장탱크(11)로 LNG를 이송하여 저장하게 된다.The LNG line 21 bites into the floating type lubrication facility and transports the LNG to the LNG storage tank 11 and stores the LNG.

이후, LNG 저장탱크(11)에 저장된 LNG는 가스 생산설비(13)로 보내져 재기화 과정을 거쳐 천연가스를 생산하게 된다.Thereafter, the LNG stored in the LNG storage tank 11 is sent to the gas production facility 13 and is regenerated 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 land-side receipt destination 23 using the submarine gas discharge pipe 14.

그런데, 종래기술에 따른 부유식 급유설비 장치는 단순히 LNG선(21)으로부터 LNG를 공급받아 저장한 후 재기화시켜 육상의 수급처(23)에 공급만 하는 단조로운 기능만을 제공하므로 정작 액화천연가스를 공급하는 LNG선(21)은 추진용 연료를 다른 곳에서 충전해야하는 불편함이 있었을 뿐만 아니라, LNG 저장탱크(11)에 저장된 액화가스를 운반하는 LNG 벙커링 선반도 추진용 연료를 다른 곳에서 충전해야 하는 문제점이 있었다.
However, since the floating type oil supply facility apparatus according to the prior art provides only a simple function of supplying LNG from the LNG line 21, storing it, and regenerating it, and supplying the LNG to the land receivers 23, The supplying LNG line 21 is not only inconvenient to charge the propelling fuel elsewhere but also the LNG bunkering shelf carrying the liquefied gas stored in the LNG storage tank 11 must be charged elsewhere .

도시한 바와 같이, 본 발명에 따른 부유식 급유설비 장치는 육상(1)으로부터 일정거리 떨어진 해상에 계류하는 부유식 급유선(100)과, 상기 부유식 급유선(100)에 설치되며 LNG선(200)으로부터 LNG를 공급받아 저장하는 LNG 저장탱크(110)와, 상기 LNG 저장탱크(110)에 저장된 LNG를 재기화시켜 가스를 생산하는 가스 생산설비(120)와, 재기화된 가스 및 LNG 적하역 과정에서 발생되는 증발가스(BOG)를 연료로 하여 전기를 생산하는 전기 생산설비(130)와, 상기 LNG 저장탱크(110)에 저장된 LNG를 LNG 벙커링 선박(300)으로 공급하는 급유설비(140)와, 상기 가스 생산설비(120)에서 생산된 가스를 육상으로 공급하는 해저 가스 송출관(150)과, 상기 전기 생산설비(130)에서 생산된 전기를 육상으로 공급하는 해저 송전선(160)과, 연료공급선(400)으로부터 추진용 연료를 공급받아 저장하는 연료저장탱크(170)와, 상기 연료저장탱크(170)에 저장된 연료를 상기 LNG선(200) 또는 상기 LNG 벙커링 선박(300)으로 연료를 공급하는 연료 송출관(180)을 포함하여 구성된다.As shown in the figure, the float type oil supply system according to the present invention includes a float type oil supply line 100 moored at a certain distance from the land 1, an LNG line 200 installed on the floating oil supply line 100, An LNG storage tank 110 for receiving and storing LNG from the LNG storage tank 110, a gas production facility 120 for producing gas by regenerating the LNG stored in the LNG storage tank 110, An LNG storage tank 110 and an LNG bunkering vessel 300. The LNG bunkering vessel 300 is connected to the LNG bunkering vessel 300 through an electricity generating facility 130 for generating electricity using the evaporated gas BOG generated in the LNG storage tank 110, A submarine gas delivery pipe 150 for supplying the gas produced in the gas production facility 120 to the sea level, a submarine transmission line 160 for supplying the electricity produced in the electricity production facility 130 onshore, The fuel for propulsion is supplied from the supply line 400 and stored A fuel storage tank 170 and a fuel delivery pipe 180 for supplying fuel stored in the fuel storage tank 170 to the LNG line 200 or the LNG bunkering vessel 300.

먼저, 상기 부유식 급유선(100)은 해상에 떠 있는 부유식 구조물로서, LNG선(200)으로부터 연료를 공급받아 저장하는 LNG 공급의 허브(Hub)역할을 수행한다.The float type oil supply line 100 is a floating structure floating on the sea and serves as a hub for LNG supply to receive and store fuel from the LNG line 200.

그리고, 상기 부유식 급유선(100)은 해상에 안정적으로 계류할 수 있도록 계류설비(미도시)에 의해 고정된다. 상기 계류설비라 함은 닻이나 로프 등을 이용해 해저와 부유식 급유선(100) 사이를 연결하는 구조물이다.The float type oil supply line 100 is fixed by a mooring facility (not shown) so as to stably moor at sea. The mooring facility is a structure that connects the bottom of the sea to the floating oil supply line 100 by using an anchor, a rope or the like.

이러한 상기 부유식 급유선(100)은 육상으로부터 일정거리 떨어진 해상에 계류함으로써, LNG선(200)이 육상(1)의 안벽으로 접안해야하는 시간과 노력을 줄일 수 있는 장점이 있다.The float type oil supply line 100 is advantageous in that it can reduce the time and effort required for the LNG line 200 to beret to the inner wall of the land 1 by mooring at a distance from the land.

다시 말해, 부유식 급유선(100)은 기존의 육상 LNG 저장탱크에 비해 선박 접안을 위한 별도의 안벽/방파제와 같은 부수적인 설비가 필요 없고, 도시 근처에 LNG 저장탱크가 있을 경우 발생할 수 있는 안전문제 및 민원문제 등을 해소할 수 있다.In other words, the floating feedwater line 100 does not require additional facilities such as a seawall / breakwater for berthing the ship compared to existing land LNG storage tanks, and does not require a safety problem that may occur if there is an LNG storage tank near the city And civil complaints.

한편, 상기 부유식 급유선(100)에는 LNG 저장탱크(110), 가스 생산설비(120), 전기 생산설비(130) 및 급유설비(140)가 설치된다.The LNG storage tank 110, the gas production facility 120, the electricity production facility 130, and the oil supply facility 140 are installed in the floating oil supply line 100.

상기 LNG 저장탱크(110)는 상기 LNG선(200)으로부터 LNG를 공급받아 저장하는 역할을 수행한다.The LNG storage tank 110 receives LNG from the LNG line 200 and stores the LNG.

상기 가스 생산설비(120)는 상기 LNG 저장탱크(110)에 저장된 LNG를 재기화시켜 가스를 생산하는 역할을 수행한다.The gas production facility 120 regenerates LNG stored in the LNG storage tank 110 to produce gas.

상기 전기 생산설비(130)는 상기 가스 생선설비(120)에 의해 기화된 가스와 LNG 적하역 과정에서 발생되는 증발가스(BOG)를 연료로 하여 전기를 생산하는 역할을 수행한다.The electricity production facility 130 serves to generate electricity using the gas vaporized by the gas fish plant 120 and the evaporated gas (BOG) generated in the LNG cargo unloading process.

상기 급유설비(140)는 상기 LNG 저장탱크(110)에 저장된 LNG를 LNG 벙커링 선박(300)으로 공급하는 역할을 수행한다.The refueling facility 140 serves to supply the LNG stored in the LNG storage tank 110 to the LNG bunkering vessel 300.

또한, 상기 부유식 급유선(100)에는 전기 생산설비(130)와 가스 생산설비(120)로부터 추출된 전기 및 가스를 육상(1)으로 공급할 수 있도록 안내하는 해저 송전선(160) 및 해저가스 송출관(150)를 더 포함하여 구성된다.The floating oil supply line 100 is provided with a submarine power transmission line 160 for guiding electricity and gas extracted from the electricity production facility 130 and the gas production facility 120 to the land area 1, (150).
