Description

쌍동선형 엘엔지 플로터Catenary type angene plotter
본 발명은 쌍동선형 엘엔지 플로터에 관한 것으로서, 보다 상세하게는 엘엔지선체의 인접 측부에 부유체를 마련하여 이들 상에 액화설비를 연결하여 지지되도록 하는 동시에 부유체의 수위조절수단을 통해 액화설비가 수평을 유지하면서 안정적으로 지지될 수 있도록 함으로써, 기본적으로 엘엔지선체와 부유체를 이용한 쌍동선 방식으로 엘엔지 플로터 전체에 대한 안정성이 향상되도록 함은 물론 기존 엘엔지선의 개조 없이 액화설비의 설치가 용이하고 신속하게 되도록 하는 쌍동선형 엘엔지 플로터에 관한 것이다.[0001] The present invention relates to a catenary line type ENGINE FLOTTER. More particularly, the present invention relates to a catenary type ENGINE FLOTTER, So that the stability of the entirety of the ELENGE plotter can be improved by the catamaran method using basically the ELENG Hull and the float, and the liquefaction facility can be installed easily and quickly without modification of the existing ELENGE line. To a catenary type ELENGE plotter.
일반적으로, 엘엔지 플로터(LNG Floater ; LNG 부유식 저장 및 생산 설비)는 바지(Barge) 형태의 부유물에 엘엔지(LNG) 혹은 천연가스(Natural Gas)를 생산하는 설비를 갖춘 해상 설비를 말한다.In general, the LNG Floater (LNG Floating Storage and Production Facility) is a marine facility equipped with facilities to produce LNG or natural gas in the form of barge floats.
이러한 엘엔지 플로터(LNG Floater)는 엘엔지(LNG)를 저장하는 화물창의 형상에 따라 상부 설비의 배치가 달라지는데, 예를 들어, 화물창이 모스(MOSS)인 경우에는 엘엔지의 Sloshing(출렁거림) 문제가 없어 안전하다고 인식되고 있으나 엘엔지를 생산하는 FPSO(부유식 원유생산 저장장치)를 제작하거나 기존 운항중인 엘엔지선을 LNG FPSO로 개조하는데 공간적 제약이 생겨 필요 이상의 면적이 요구된다.In such an LNG floater, the arrangement of the upper equipment differs depending on the shape of the cargo hold storing the LNG. For example, when the cargo holds the MOSS, there is no sloshing problem of the elongate Although it is recognized as safe, there is a space constraint in the production of FPSO (floating oil production storage device) that produces the ELENGE or the conversion of the existing operating ELNG into the LNG FPSO.
그리고, 화물창이 맴브레인(Membrane)인 경우, 출렁거림의 문제 등으로 엘엔지 플로터의 화물창으로 사용하는데 많은 제약이 있으며, 특히 화물창의 절연(Insulation) 부분에 대한 강도를 크게 증가시켜야 하며, 또한 개조의 경우에는 화물창의 일부를 변경하여 강화 절연(Insulation) 자재로 대체하여야 한다.Further, when the cargo hold is a membrane, there are many restrictions on the use of the float as a cargo hold of the Eljen plotter due to a problem of swelling, etc. In particular, the strength of the insulation portion of the cargo hold must be greatly increased, , A portion of the cargo hold is to be replaced and replaced with a reinforced insulation material.
그리고, 화물창이 에스피비(SPB)인 경우에는 출렁거림에 대한 문제가 없을 것으로 예상되고 있어서 엘엔지 플로터의 화물창으로 사용하고는 있으나 맴브레인(Membrane) 방식 대비 생산 비용이 많이 든다.If the cargo hold is SPB, it is expected that there will be no problem of swaying. Therefore, it is used as a cargo window of the ELENGE plotter, but the production cost is higher than that of the membrane method.
한편, 엘엔지 플로터를 만들기 위해서 기존 엘엔지선을 개조하거나 신조하는 경우 각 화물창 형상에 따른 문제점을 살펴보면 다음과 같다.On the other hand, in the case of retrofitting or renovating a conventional ELENGE line to make an ELENG floater, the problems depending on the shape of each cargo hold are as follows.
우선, 맬브레인(Membrane)의 경우는 출렁거림 문제로 중간에 격벽을 설치하고 절연박스(Insulation Box)의 강도가 증가한 특별한 박스(Box)를 사용해야 한다. First of all, in the case of a membrane, it is necessary to install a bulkhead in the middle due to the swinging problem and to use a special box with an increased strength of the insulation box.
그리고, 운항하는 엘엔지선을 개조하여 Floater를 만드는 경우에는 화물창 내부의 절연박스(Insulation Box)를 교체하여 보강하여야 하므로 엘엔지선을 이용하여 개조하지 않고 LNG RV(엘엔지 알브이)를 이용하여 개조하여야 하는데, 이 경우 LNG RV를 두 개로 나누어서 중간에 액화설비를 설치하여야 하기 때문에 중간을 절단하고 다시 용접하여 결합하는데 있어서 카고(Cargo) 화물창의 절연박스(Insulation Box)에 손상이 가해져서 화물창을 재 작업하여야 하는 문제점 발생한다. In addition, when constructing a Floater by modifying the operating ELENGE line, it is necessary to retrofit by inserting the Insulation Box inside the cargo hold. Therefore, it should be remodeled using LNG RV (ElNGAlV) In this case, the LNG RV should be divided into two and the liquefaction facility should be installed in the middle. Therefore, the insulation box of the cargo cargo is damaged in the middle cutting and re-welding to rework the cargo hold .
그리고, 모스(MOSS) 타입의 경우, 신조를 하던 개조를 하던 액화설비를 설치하기에는 공간이 비좁고 열교환기와 컬럼(Column)의 높이가 높아 설치할 공간이 매우 부족하게 되는 문제점이 있었다. In addition, in the case of the MOSS type, there is a problem in that space for installation of a liquefaction facility, which has been renovated, is too narrow, and the height of a heat exchanger and a column is high, and a space for installation is very short.
현재 중소형의 가스전을 개발하기 위하여 중형사이즈의 액화설비를 갖춘 엘엔지 플로터가 시장에서 요구되고 있는 실정이다.Currently, there is a demand in the market for an ELNGE plotter equipped with a medium sized liquefaction facility in order to develop a small and medium-sized gas field.
따라서, 엘엔지 플로터를 신조하기에는 비용이 많이 들어 시장에서는 운송 계획이 없는 엘엔지선을 개조하여 사용하려는 의도가 있다.Therefore, there is an intention to convert the ELENGE line, which has no transportation plan, in the market because it is expensive to renovate the ELENGE plotter.
본 발명은 이와 같은 문제점을 해결하기 위해 안출된 것으로서, 엘엔지선체의 인접 측부에 부유체를 마련하여 이들 상에 액화설비를 연결하여 지지되도록 하는 동시에 부유체의 수위조절수단을 통해 액화설비가 수평을 유지하면서 안정적으로 지지될 수 있도록 함으로써, 기본적으로 엘엔지선체와 부유체를 이용한 쌍동선 방식으로 엘엔지 플로터 전체에 대한 안정성이 향상되도록 함은 물론 기존 엘엔지선의 개조 없이 액화설비의 설치가 용이하고 신속하게 되도록 하는 쌍동선형 엘엔지 플로터를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been conceived in order to solve such problems, and it is an object of the present invention to provide a floating body on the adjacent side of an angular hull and to connect and support a liquefaction facility thereon, So that the stability of the entirety of the angene floater can be improved by a catamaran method using an angular hull and float basically, and the installation of the liquefaction facility can be easily and quickly performed without modification of the existing angene line It is an object of the present invention to provide a catenary type ELENGE plotter.

여기서, 상기 수위조절수단은, 상기 부유체(20)에 압축공기를 공급하여 이 부유체(20)의 제2밸러스트탱크(21) 내의 밸러스트수가 엘엔지선체(10)의 제1밸러스트탱크(11)로 밀려 유입되도록 하는 공기압축기(50)와, 이 공기압축기(50)와 일단부가 연결되고 그 타단부가 부유체(20)의 상단부 일측에 연통되어 상기 공기압축기(50)의 압축공기를 부유체(20)로 공급하는 공급배관(60) 및 이 공급배관(60)의 인접부에 배치되어 부유체(20) 내부의 공기를 외부로 배출시키는 배출배관(70)을 포함하여 구성된다.The water level adjusting means supplies compressed air to the float 20 so that the ballast water in the second ballast tank 21 of the float 20 is discharged to the first ballast tank 11 of the Elongated Ship 10, (50), one end of which is connected to one end of the air compressor (50), and the other end of which communicates with one side of the upper end of the float (20) And a discharge pipe 70 disposed in the vicinity of the supply pipe 60 for discharging the air inside the float 20 to the outside.
그리고, 상기 공급배관(60) 상에 공기압축기(50)로부터 공급되는 압축공기의 공급량을 조절하기 위한 공급조절밸브(61)가 마련되어 있고, 또한, 상기 배출배관(70) 상에 부유체(20)의 압축공기가 외부로 배출되는 배출량을 조절하기 위한 배출조절밸브(71)가 마련되어 있다.A supply control valve 61 for regulating the supply amount of the compressed air supplied from the air compressor 50 is provided on the supply piping 60 and a float 20 And a discharge control valve 71 for controlling the discharge amount of the compressed air of the compressed air to the outside.
여기서, 상기 공기압축기(50)는 기존 엘엔지선체(10)에 사용되고 있는 펌핑시스템을 사용하여 공기의 가압/감압을 반복함으로써 부유체(20)의 밸러스트수(Ballast Water)의 수위를 조절할 수 있도록 하는 것이 바람직하다.Here, the air compressor (50) can regulate the water level of the ballast water of the float (20) by repeating the depressurization / depressurization of the air by using the pumping system used in the conventional ELHNE .
그리고, 상기 수위를 조절할 경우, 엘엔지선체(10)의 기울기를 고려하여 제어할 수 있도록 기울기감시시스템(미도시)과 연계시켜 사용하는 것이 바람직하다.When the water level is adjusted, it is preferable to use it in conjunction with a tilt monitoring system (not shown) so that the water level can be controlled in consideration of the inclination of the angular hull 10.
이러한 구성에 따른 본 발명의 일 실시예인 쌍동선형 엘엔지 플로터는 엘엔지선체(10)의 인접 측부의 해수면 상에 부유체(20)를 띄운 후 이들 엘엔지선체(10)와 부유체(20)의 각 밸러스트탱크(11,21)를 연통배관(40)으로 연통시켜 서로 간의 밸러스트수를 공유시킨다.In the catenary line type ENGINE plotter according to this embodiment of the present invention, float 20 is floated on the sea surface of the adjacent side of the ELHYN 10, The tanks 11 and 21 are communicated with the communication pipe 40 to share the ballast water between them.
그런 다음, 이들의 상부에 액화설비(30)의 양측이 각각 연결 지지되도록 하여 액화설비(30)를 설치한다.Then, the liquefaction facility 30 is installed so that both sides of the liquefaction facility 30 are connected and supported on the upper portion thereof.
그리고, 부유체(20)에는 밸러스트수의 수위조절수단인 공급배관(60)과 배출배관(70)을 연결하고 공급배관(60)에 공기압축기(50)를 설치함으로써, 본 발명의 쌍동선형 엘엔지 플로터의 제작이 완료된다.The float 20 is connected to a supply piping 60 and a discharge piping 70 which are water level adjusting means of the ballast water and an air compressor 50 is installed in the supply piping 60. As a result, The production of the plotter is completed.
이렇게 완성된 엘엔지 플로터는 해상에 부유된 상태에서 액화설비(30)를 통해 엘엔지 또는 천연가스를 생산할 수 있게 되는 것이다.The completed ElNG floater is capable of producing an elongated or natural gas through the liquefaction facility 30 in a floated state on the sea.
그리고, 이렇게 엘엔지 또는 천연가스 생산 중에 액화설비(30)의 기울기가 맞지 않아 불안정한 상태가 되면 이에 따라 부유체(20)의 밸러스트를 조절하여 액화설비(30)가 안정된 상태가 되도록 한다.When the liquefaction facility 30 is in an unstable state due to the incline of the liquefaction facility 30 during the production of the liquefied natural gas, the ballast of the float 20 is adjusted to stabilize the liquefaction facility 30. [
즉, 부유체(20)가 엘엔지선체(10)보다 높은 위치에 위치하여 액화설비(30)가 엘엔지선체(10) 측으로 기울어져 있을 경우에는, 부유체(20)의 제2밸러스트탱크(21) 내부의 기압이 높고 밸러스트수가 적어 부유체(20)가 떠올라있는 상태이기 때문에, 배출배관(70)의 배출조절밸브(71)를 조작하여 기압을 외부로 배출함으로써 부유체(20)와 엘엔지선체(10)와의 밸런스를 맞출 수 있게 된다.That is, when the float 20 is located at a higher position than the angular hull 10 and the liquefaction facility 30 is inclined toward the angular hull 10, the second ballast tank 21 of the float 20 is floated, The air pressure is discharged to the outside by operating the discharge control valve 71 of the discharge pipe 70 because the inside air pressure is high and the ballast water is small and the float 20 is floating, 10).
이때, 공급배관(60)의 공급조절밸브(61)는 닫혀있는 상태를 유지하고 있어야 한다.At this time, the supply control valve 61 of the supply pipe 60 must remain closed.
이와 반대로, 부유체(20)가 엘엔지선체(10)보다 낮은 위치에 위치하여 액화설비(30)가 부유체(20) 측으로 기울어져 있을 경우에는, 부유체(20)의 제2밸러스트탱크(21) 내부의 기압이 낮고 밸러스트수가 많아 부유체(20)가 가라앉은 상태이기 때문에, 이때는 공기압축기(50)를 작동시키고 공급배관(70)의 공급조절밸브(61)를 조작하여 제2밸러스트탱크(21) 내부로 고압을 주입하여 밸러스트수를 제1밸러스트탱크(11)로 일부 유입시켜 부유체(20)가 가벼워지도록 함으로써 부유체(20)와 엘엔지선체(10)와의 밸런스를 맞출 수 있게 되는 것이다.On the other hand, when the float 20 is positioned lower than the angular hull 10 and the liquefaction facility 30 is inclined toward the float 20, the second ballast tank 21 The air compressor 50 is operated and the supply control valve 61 of the supply pipe 70 is operated to operate the second ballast tank (not shown) by operating the air compressor 50 and operating the supply control valve 61 of the supply pipe 70 at this time because the internal air pressure is low and the ballast water is large, The ballast water is injected into the first ballast tank 11 by injecting a high pressure into the first ballast tank 21 so that the float 20 is lightened so that the balance between the float 20 and the angular hull 10 can be matched .
이때, 배출배관(70)의 배출조절밸브(71)는 닫혀있는 상태를 유지하고 있어야 한다.At this time, the discharge control valve 71 of the discharge pipe 70 should be kept closed.
이와 같이, 실시간적으로 수위조절수단이 작동되면서 액화설비(30)가 안정된 상태를 지속적으로 유지하면서 가스 생산 작업을 수행할 수 있게 되는 것이다. In this way, the water level adjusting means is activated in real time, so that the liquefaction facility 30 can perform the gas production operation while maintaining the stable state.
