Description

발전플랜트가 탑재되는 부유식 해양구조물 및 그 부유식 해양구조물의 거주구 설치구조{Floating Facility Mounted Power Plant and Accomodation Install Structure Thereof} BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a float-type offshore structure having a power plant,

본 발명은 전력을 생산하는 발전플랜트가 탑재되는 부유식 해양구조물에 관한 것으로, 좀더 상세하게는 발전실을 선체의 화물창 데크 하부로 배치하되, 거주구가 선체의 후단부 내부에 배치되는 부유식 해양구조물 및 그 부유식 해양구조물의 거주구 설치구조에 관한 것이다.The present invention relates to a floating offshore structure on which a power generating plant for generating electric power is mounted. More particularly, the present invention relates to a floating offshore structure in which a power generation room is disposed below a deck of a cargo hold of a hull, Structure and the floating structure of the floating structure.

근래 LNG(Liquefied Natural Gas)나 LPG(Liquefied Petroleum Gas) 등의 액화가스의 소비량이 전 세계적으로 급증하고 있는 추세이다.Recently, the consumption of liquefied gas such as Liquefied Natural Gas (LNG) and Liquefied Petroleum Gas (LPG) has been rapidly increasing worldwide.

액화가스는 육상 또는 해상의 가스배관을 통해 가스 상태로 운반되거나, 액화된 상태로 액화가스 운반선에 저장된 채 원거리의 소비처로 운반된다.The liquefied gas is transported in a gaseous state through land or sea gas pipelines, or in a liquefied state and stored in a liquefied gas carrier and transported to a distant consumer.

LNG나 LPG 등의 액화가스는 천연가스 혹은 석유가스를 극저온(LNG의 경우 대략 -163℃)으로 냉각하여 얻어지는 것으로, 가스 상태일 때보다 그 부피가 대폭적으로 감소하므로 해상을 통한 원거리 운반에 매우 적합하다.Liquefied gas such as LNG or LPG is obtained by cooling natural gas or petroleum gas at cryogenic temperature (approximately -163 ℃ in case of LNG), and its volume is considerably reduced compared to when it is in gas state, so it is very suitable for long distance transportation through sea Do.

액화가스 운반선은 액화가스를 싣고 바다를 운항하여 육상 소요처에 이 액화가스를 하역하기 위한 선박이며, 이를 위해, 액화가스의 극저온에 견딜 수 있는 저장탱크(흔히, '화물창'이라 함)를 포함한다.The liquefied gas carrier is a vessel for loading the liquefied gas into a land area by carrying liquefied gas and operating the sea. For this purpose, a storage tank (often referred to as a 'cargo window') capable of withstanding cryogenic temperatures of liquefied gas is included do.

이와 같이 극저온 상태의 액화가스를 저장할 수 있는 저장탱크가 마련된 해상 구조물의 예로서는 액화가스 운반선 이외에도 LNG RV (Regasification Vessel)와 같은 선박이나 LNG FSRU (Floating Storage and Regasification Unit), LNG FPSO (Floating, Production, Storage and Off-loading)와 같은 구조물 등을 들 수 있다.Examples of maritime structures having storage tanks capable of storing liquefied gas at cryogenic temperatures include ships such as LNG RV (Regasification Vessel), LNG FSRU (Floating Storage and Regasification Unit), LNG FPSO (Floating, Production, Storage and off-loading), and the like.

LNG RV는 자력 항해 및 부유 가능한 액화가스 운반선에 LNG 재기화 설비를 설치한 것이고, LNG FSRU는 육상으로부터 멀리 떨어진 해상에서 LNG 수송선으로부터 하역되는 액화 천연가스를 저장탱크에 저장한 후 필요에 따라 액화 천연가스를 기화시켜 육상 수요처에 공급하는 해상 구조물이다.LNG RV is a LNG regeneration facility installed on a self-propelled and floating liquefied gas carrier. The LNG FSRU stores liquefied natural gas unloaded from an LNG carrier offshore at sea and stored in a storage tank, It is the offshore structure that supplies gas to the demand of the land by vaporizing.

그리고, LNG FPSO는 채굴된 천연가스를 해상에서 정제한 후 직접 액화시켜 저장탱크 내에 저장하고, 필요시 이 저장탱크 내에 저장된 LNG를 LNG 수송선으로 옮겨싣기 위해 사용되는 해상 구조물이다.The LNG FPSO is a marine structure used to purify the natural gas mined in the sea, directly liquefy it, store it in the storage tank, and transfer the LNG stored in the storage tank to the LNG transport if necessary.

천연가스의 액화 온도는 상압에서 약 -163℃의 극저온이므로, LNG는 그 온도가 상압에서 -163℃ 보다 약간만 높아도 증발된다.Since the liquefaction temperature of natural gas is a cryogenic temperature of about -163 ° C at normal pressure, LNG is evaporated even if its temperature is slightly higher than -163 ° C at normal pressure.

종래의 LNG 운반선의 경우를 예를 들어 설명하면, LNG 운반선의 LNG 저장탱크는 단열처리가 되어 있기는 하지만, 외부의 열이 LNG에 지속적으로 전달되므로, LNG 운반선에 의해 LNG를 수송하는 도중에 LNG가 저장탱크 내에서 지속적으로 기화되어 저장탱크 내에 증발가스(BOG; Boil-Off Gas)가 발생한다.For example, in the case of a conventional LNG carrier, the LNG storage tank of the LNG carrier is heat-treated, but since the external heat is continuously transferred to the LNG, LNG is transported by the LNG carrier, The boil-off gas (BOG) is generated in the storage tank by continuously vaporizing in the storage tank.

선박에서 배출되는 폐기가스 중 국제 해사 기구(International Maritime Organization)의 규제를 받고 있는 것은 질소산화물(NOx)과 황산화물(SOx), 그리고 이산화탄소(CO2)이다. 특히, 질소산화물(NOx)과 황산화물(SOx)의 경우, 1997년 해상오염 방지협약(MARPOL; The Prevention of Marine Pollution from Ships) 의정서를 통하여 제기되고, 8년이라는 긴 시간이 소요된 후 2005년 5월에 발효요건을 만족하여 현재 강제규정으로 이행되고 있다.Of the waste gases emitted from vessels, nitrogen oxides (NOx), sulfur oxides (SOx), and carbon dioxide (CO 2 ) are regulated by the International Maritime Organization. Particularly, in the case of nitrogen oxide (NOx) and sulfur oxides (SOx), it was submitted through the Protocol of the Maritime Pollution Prevention Convention (MARPOL) in 1997, In May, the requirements for the fermentation were satisfied and the regulations are being implemented.

참고로, 선박에 사용되는 주엔진은 2 스트로크 엔진(Low Speed Disel Engine)으로 HFO(Heavy fuel oil), MDO(Marine disel oil), MGO(Marin gas oil)을 주연료로 하며, 압축 착화방식으로 작동한다.For reference, the main engine used for the ship is a 2-stroke engine (Low Speed Disel Engine), which uses HFO (heavy fuel oil), MDO (marine disel oil) and MGO (marine gas oil) It works.

즉, 실린더에서 구동되는 피스톤에 의해 실린더 공간으로 흡입되는 공기를 고온과 고압으로 압축하여 연료를 매우 미세하게 분사하면 내부의 고온에 의해 별도의 점화장치 없이 폭발하며, 여기서 얻은 폭발력에 의해 구동축에 동력을 얻게 된다. That is, when the air sucked into the cylinder space by the piston driven by the cylinder is compressed to a high temperature and a high pressure and the fuel is injected very finely, the explosion occurs without a separate ignition device due to the high temperature inside. .

또한, 선박에 사용되는 엔진으로 ME엔진(전자 제어엔진)이 개발된 바가 있다. 기존의 캠 구동 엔진에서는 100% 부하 등의 지정된 한 부하에서만 연소가 최적화되던 것이, 상기 전자제어 엔진에서는 각 부분 부하에 적합한 연료분사 및 배기 변 개폐시점을 컴퓨터 프로그램에 의해 정확히 제어해 줌으로써, 부분 부하에서도 최적의 연소가 일어나게 하는 원리로 작동된다.In addition, an ME engine (electronic control engine) has been developed as an engine used in ships. In the conventional cam drive engine, the combustion is optimized only in a designated load such as a 100% load. In the electronic control engine, the fuel injection and the exhaust valve opening / closing timing suitable for each partial load are accurately controlled by a computer program, Which is a principle that causes optimal combustion to occur.

최근에 선박에 사용되는 엔진으로는, 질소산화물(NOx), 황산화물(SOx), 이산화탄소 배출량을 저감하기 위하여 ME-GI 엔진이 개발되었다.In recent years, ME-GI engines have been developed to reduce NOx, SOx and CO2 emissions.

ME-GI 엔진은 LNG(Liquefied Natural Gas)를 극저온에 견디는 저장탱크에 저장하여 운반하도록 하는 LNG 운반선 등과 같은 해상 구조물에 설치될 수 있으며, 이 경우 천연가스를 연료로 사용하게 되며, 그 부하에 따라 대략 150 - 400 bara(절대압력) 정도의 고압의 가스 공급 압력이 요구된다.The ME-GI engine can be installed on marine structures such as LNG carriers that store LNG (Liquefied Natural Gas) in cryogenic storage tanks and transport them. In this case, natural gas is used as fuel, A high gas supply pressure of about 150-400 bara (absolute pressure) is required.

도 1에는 발전플랜트를 탑재한 바지선(1)을 개략적으로 도시하였다. 바지선의 선체(11)에 연료탱크(13)가 탑재되고, 바지선(1)의 화물창 데크(D) 상부에 발전플랜트의 각종 설비들(20)이 탑재되는 형태이다.Fig. 1 schematically shows a barge 1 on which a power plant is mounted. The fuel tank 13 is mounted on the hull 11 of the barge and various facilities 20 of the power generation plant are mounted on the upper portion of the cargo hold deck D of the barge 1. [

이처럼, 바지선과 같은 부유식 해상 구조물에 발전플랜트를 설치할 경우, 발전 및 송전 설비들은 스파크나 누전, 합선 등에 의해 화재의 원인을 제공할 위험성이 있으므로, 부유식 해상 구조물에는 발전플랜트 외에도 각종 화재 발생을 막기 위한 안전장치가 설치될 것이다.Thus, when a power plant is installed in a floating structure such as a barge, there is a risk that the power generation and transmission facilities may cause a cause of fire by spark, short-circuit, short-circuit, etc. Therefore, A safeguard to prevent it will be installed.

더욱이 LNG FPSO와 같은 원유 또는 가스를 시추ㆍ생산ㆍ정제ㆍ저장하는 부유식 해상 구조물들은 폭발성 가스를 다루는 해상 구조물이므로, 폭발성 가스의 유출 사고로 해상 구조물의 화재ㆍ폭발의 위험성은 더욱더 높아지고, 이를 대비하기 위한 각종 안전 설비를 더 구비하여야 한다.Furthermore, the floating marine structures drilling, producing, refining and storing crude oil or gas such as LNG FPSO are marine structures dealing with explosive gases, so that the risk of fire and explosion of marine structures is further increased due to the leakage of explosive gas. And other safety equipment.

이와 같이, 기존의 폭발성 가스나 물질을 취급하는 부유식 해상 구조물은 폭발을 방지하기 위한 각종 추가설비를 필요로 하며, 이로 인해 부유식 해상 구조물의 데크 상부에는 발전플랜트의 각종 설비들에, 각종 안전 설비까지 더해지면서 다른 설비들을 설치할 공간이나 작업공간이 없어질 수 있다. In this way, floating structure for handling explosive gas or material requires various additional equipment to prevent explosion. Thus, the upper part of the floating floating structure is provided with various facilities of power plant, various safety As the equipment is added, space or work space for installing other facilities may be lost.

이러한 문제들로 인해 해상 구조물에 대형 발전플랜트를 탑재하여 많은 전력을 생산하는 것은 곤란하며, 해상 구조물 자체에 필요한 전기를 공급하는 정도의 소규모 발전만 이루어질 수 있다. Due to these problems, it is difficult to produce a large amount of electric power by installing a large-scale power plant on the offshore structure, and only small-scale power generation that can supply electricity necessary for the offshore structure itself can be achieved.

또한, 거주구가 선체의 상부에 위치하여 작업 공간에 제약을 받으며, 전자파에 쉽게 노출되는 문제점을 예상할 수 있는바, 이러한 문제점을 해결하고자 본 발명을 제안한다.In addition, since the residence is located at the upper part of the hull, it is restricted by the work space and can easily be exposed to electromagnetic waves. Accordingly, the present invention is proposed to solve such a problem.

본 발명은 발전실을 선체의 화물창 데크 하부에 설치되며, 거주구가 화물창 데크 하부 후단부에 설치됨으로써, 화물창 데크 상부의 공간확보가 용이하며, 발전효율을 높이고, 전자파를 차단하며, 작업자가 발전실을 모니터링하거나 이동하기 쉬운 부유식 해양구조물 및 그 부유식 해양구조물의 거주구 설치구조를 제공함에 그 목적이 있다.
