Abstract

The present invention relates to a fuel supply method and system for a barge mounted power plant. The fuel supply system for a barge mounted power plant of the present invention comprises: a marine production facility disposed on shore in order to produce oil and gas; a gas processing apparatus for processing the oil and gas produced in the marine production facility; and a gas supply line for supplying the gas processed in the gas processing apparatus to a barge mounted power plant. The present invention enables the efficient use of gas which is a by-product of a marine production facility. That is, gas, which is a by-product, can be directly supplied to a barge mounted power plant and utilized to generate electricity, unlike in an existing marine production facility which transfers gas to a consumption site through lines for gas injection and gas export. Furthermore, since direct supply of fuel gas to a power plant is possible, separate gas storage and re-gasification facilities are not required for a barge mounted power plant.

Description

부유식 발전플랜트의 연료공급 방법 및 시스템Fuel supply method and system of floating power plant

본 발명은 부유식 발전플랜트의 연료공급 방법 및 시스템에 관한 것으로, 좀더 구체적으로는 가스 연료를 이용하여 전력을 생산하는 부유식 발전플랜트에 연료를 공급함에 있어서 근해에 설치된 해양 생산설비(Fixed platform)로부터 가스연료를 부유식 발전플랜트에 직접 공급할 수 있는 부유식 발전플랜트의 연료공급 방법 및 시스템에 관한 것이다.The present invention relates to a fuel supply method and system for a floating power plant, and more particularly, to a fuel for a floating power plant that produces power using gas fuel, a offshore production facility (Fixed platform) installed near the sea. The present invention relates to a fuel supply method and system for a floating power plant that can directly supply gas fuel to a floating power plant.

최근에는 친환경적인 발전에 대한 요구로 천연가스를 이용한 발전에 대한 관심이 증가하고 있다. 특히, 폐열을 회수하여 스팀 터빈을 구동하는 복합화력발전 기술이 등장함에 따라 가스 발전의 효율 증대와 가스 가격의 하락 안정에 따른 가스 발전 수요가 점점 증대되고 있는 실정이다.Recently, as the demand for environmentally friendly power generation, interest in power generation using natural gas is increasing. In particular, with the emergence of a combined cycle power generation technology that recovers waste heat and drives a steam turbine, demand for gas power generation is increasing due to increased efficiency of gas power generation and stabilization of falling gas prices.

한편, 전력공급이 원활하지 않은 신흥개발국 등에서 가스 발전에 대한 관심이 높아지고 있는데, 가스 발전은 그 특성상 육지에 가스 저장소 등과 같은 가스 인프라가 갖추어야만 발전이 가능하기 때문에 개발에 제한이 많았다. 특히, 여러 개의 섬들로 이루어진 동남아시아 국가의 경우에는 대용량의 가스 발전을 하는 데 어려움이 많았다.On the other hand, there is a growing interest in gas power generation in emerging economies with poor power supply. However, gas power generation has been limited in terms of development because it is possible to generate electricity only when there is a gas infrastructure such as gas storage on land. In particular, in the case of Southeast Asian countries consisting of several islands, it was difficult to generate a large amount of gas.

이와 같은 문제점을 해결하기 위하여, FSRU(Floating Storage Re-gasfication Unit)라는 부유식 해상 가스 저장 재기화 설비 선이 등장하게 되었으며, 이러한 해상 가스 저장 재기화 설비 선을 이용하여 육지의 발전소에 가스를 공급하게 되었다.In order to solve this problem, a floating offshore gas storage regasification plant line called Floating Storage Re-gasfication Unit (FSRU) has emerged, and the offshore gas storage regasification plant line is used to supply gas to land power plants. Was done.

그러나, 이와 같은 FSRU를 이용한 육지에서의 발전은 해상에서의 FSRU 설치와 육지에 발전소를 건설해야 하는 이중적인 부담을 초래한다. 즉, FSRU 뿐만 아니라, 육상 발전소 건설에 따른 장소 확보와 건설비 소요를 가져오는 단점이 있었다. 특히, 육상 발전소 건설에는 많은 시간이 소요됨으로써 전력 공급을 단시간 내에 수행하는 것이 어렵다.However, such land-based development using FSRUs creates a double burden of installing FSRUs at sea and building power plants on land. That is, as well as FSRU, there was a drawback of securing the place and the cost of construction due to the construction of onshore power plants. In particular, it takes a lot of time to build a land power plant, it is difficult to perform the power supply in a short time.

한편, 기존 육상 발전플랜트 구조를 벗어나 바지선과 같은 부유식 구조물 위에 발전 플랜트가 설치된 새로운 개념의 부유식 발전플랜트가 활발하게 연구 개발되고 있지만, 발전을 위한 연료가스의 공급이 이루어져야 하므로, 육상에 가스 인프라가 갖추어지지 않은 신흥국가들에 부유식 발전플랜트 기술을 적용하기 어려운 문제가 있다.On the other hand, a new concept of a floating power plant with a power plant installed on a floating structure such as a barge is being actively researched and developed beyond the existing land power plant structure. It is difficult to apply floating power plant technology to emerging economies that do not have a global economy.

유전을 갖는 신흥국가들 중에는 통상적으로 해양 연안에 고정식 해양 생산설비를 구비하고 있고 있는바, 본 발명은 부유식 발전플랜트에 연료가스를 공급함에 있어서 기존의 근해의 해양 생산설비(Fixed platform)를 이용하여 부유식 발전플랜트에 연료가스를 직접 공급함으로써, 육상에 가스 인프라를 갖추지 않은 신흥국가들에도 부유식 발전플랜트 기술을 적용할 수 있는 부유식 발전플랜트의 연료공급 방법 및 시스템을 제공함에 첫 번째 목적이 있다.Emerging countries with oil fields are usually equipped with fixed offshore production facilities on the offshore coast. The present invention utilizes existing offshore fixed platforms to supply fuel gas to floating power plants. The first objective is to provide fuel supply methods and systems for floating power plants that can apply floating power plant technology to emerging countries that do not have a gas infrastructure on land. There is this.

또한, 본 발명은 해양 생산설비의 연료가스를 부유식 발전 플랜트에 공급함에 있어서, 해양 생산설비의 연료가스 시스템(Fuel gas system)으로부터 부유식 발전플랜트에 가스연료를 공급하거나, 또는 해양 생산설비의 웰(Well) 압력조절용 가스주입 라인(Gas injection line) 또는 외부 가스 이송용 가스 배출 라인(Gas Export line)으로부터 부유식 발전플랜트에 가스연료를 공급할 수 있는 기술을 해양 생산설비의 가스 압력 조건 및 양에 따라서 선택적으로 적용할 수 있는 부유식 발전플랜트의 연료공급 방법 및 시스템을 제공함에 두 번째 목적이 있다.In addition, the present invention is to supply the fuel gas of the offshore production facilities to the floating power plant, the gas fuel from the fuel gas system (Fuel gas system) of the offshore production facilities to the floating power plant, or The technology to supply gas fuel to the floating power plant from the well pressure gas injection line or the gas export line for external gas transfer is provided. It is a second object to provide a fuel supply method and system for a floating power plant which can be selectively applied according to the present invention.

전술한 목적을 달성하기 위하여, 본 발명의 부유식 발전플랜트의 연료공급 방법은 부유식 발전플랜트의 발전(發電)을 위하여 근해에 설치된 해양 생산설비의 가스처리 장치에서 처리한 가스를 상기 부유식 발전플랜트로 직접 공급한다.In order to achieve the above object, the fuel supply method of the floating power generation plant of the present invention is the floating power generation of the gas treated in the gas treatment apparatus of the offshore production facility installed in the offshore for power generation of the floating power generation plant Supply directly to the plant.
