Description

ＬＮＧ 선의 카고 탱크 체적 증가 설계방법{Method for enlarging the volume of Cargo tank for LNG ship}Method for enlarging the volume of cargo tank for LNG ship

본 발명은 LNG 선의 카고 탱크 체적을 증대하는 설계방법에 관한 것이다.The present invention relates to a design method for increasing the cargo tank volume of LNG carriers.

천연가스의 주요성분은 80∼85%가 메탄(CH4)가스로 되어 있고 공해물질의 함량이 지극히 적다는 이점 때문에 에너지원으로서 이용가치를 높이 평가받고 있다. 또한 천연가스를 액화하는 과정에서 먼지제거, 탈유, 탈탄산, 탈수 등의 전처리를하기 때문에 연소시에 아류산 가스가 발생하지 않고 질소탄화물의 발생이 적고 또한 CO2발생량이 다른 화석연료에 비해 훨씬 적어서 청정에너지라고 한다.The main component of natural gas is methane (CH 4 ) gas, which has a high content of pollutants and is highly valued as an energy source. In addition, since liquefaction of natural gas pretreatments such as dust removal, deoiling, decarbonation, and dehydration, arsenic gas is not generated during combustion, and nitrogen carbide is generated less, and CO 2 generation is much higher than that of other fossil fuels. It is called clean energy.

이처럼 천연가스가 에너지자원으로 등장함에 따라 국내에서도 LNG 수요가 꾸준히 증가하고 있다. 천연가스를 에너지로 이용하기 위해서는 생산기지로부터 수요지와 인수지까지 대량으로 수송할 수 있는 효율적인 운반수단이 필요하게 됐다.As natural gas emerges as an energy resource, LNG demand is steadily increasing in Korea. To use natural gas as energy, efficient transportation means are needed to transport large quantities from production bases to demand and acquisition sites.

우리 나라에서도 인도네시아 및 말레이시아 등지에서 수송선에 의하여 LNG가 도입되는데 LNG선은 탱크형식에 따라 모스(MOSS)형과 멤브레인(Membrane)형으로 나누어진다.In Korea, LNG is introduced by transport ships from Indonesia and Malaysia, etc. LNG carriers are divided into Moss and Membrane types according to the tank type.

LNG선의 탱크의 형식에 따라 분류하면 크게 독립형과 멤브레인형으로 대별된다.When classified according to the type of tank of LNG carriers, they are largely classified into independent type and membrane type.

도1에는 기존의 모스형 탱크 구조가 도시되는데, 탱크에 걸리는 하중 즉 화물 및 증기압에 의한 내압, 선체의 변형으로부터 지지구조를 통하여 전달되는 외압, 선박의 운동에 기인하는 동하중, 저온의 LNG로 인한 열응력, 슬로싱에 의한 하중, 타워(TOWER) 및 방열재 등 기타의 부착품에 의한 하중 등을 조합하여 응력레벨을 계산하고 피로수명 및 균열진전 특성을 구하기 위한 모형시험 및 정밀해석을 통하여 안전성이 입증된 탱크형식을 말한다.Figure 1 shows a conventional Mohs tank structure, the load on the tank, that is, internal pressure due to cargo and vapor pressure, external pressure transmitted through the support structure from the deformation of the hull, dynamic load due to the movement of the vessel, due to low temperature LNG Safety through model test and precision analysis to calculate stress level and calculate fatigue life and crack propagation characteristics by combining thermal stress, load by sloshing, load by tower and heat-insulating materials, etc. This is a proven tank type.

정밀 계산된 응력레벨 및 변동응력 상태하에서 20년간 운항하여도 관통균열이 발생하지 아니한다는 ELD(Endurance Limit Design) 및 관통균열이 발생하였을 때 15일간의 가혹한 해상상태하의 항해에도 그 균열이 탱크벽의 파괴를 일으키지아니한다는 LBF(Leak Before Failure) 개념에 입각한 설계로 부분 이차방벽이 허용된다.The cracks are exposed to cruising under severe sea conditions for 15 days when the endurance limit design (ELD) and through cracks occur, even though the cracks do not occur through 20 years of operation under precisely calculated stress levels and fluctuating stress conditions. Partial secondary barriers are allowed with a design based on the Leak Before Failure (LBF) concept of no destruction.

도2에는 기존의 멤브레인 형 탱크 구조가 도시되는데, 멤브레인 탱크라 함은 인접하는 선체구조에 의하여 방열재를 통하여 지지된 얇은(10mm) 막으로 구성되는 비자기지지형의 탱크(non-self-supporting tank)를 말한다. 멤브레인은 열 또는 기타의 신축이 멤브레인에 과도한 응력을 발생하지 아니하도록 설계하고 설계증기압은 0.25bar를 넘지 않는다. 화물에 직접 접촉하는 일차방벽((primary barrier)과 또 하나의 완벽한 이차방벽(secondary barrier)으로 구성된다.2 shows a conventional membrane-type tank structure, which is a non-self-supporting tank consisting of a thin (10 mm) membrane supported by a heat dissipation material by an adjacent hull structure. Say). The membrane is designed so that heat or other stretching does not cause excessive stress on the membrane and the design vapor pressure does not exceed 0.25 bar. It consists of a primary barrier and another complete secondary barrier in direct contact with the cargo.

또 다른 멤브레인 탱크는 예전의 Technigaz(현재는 GT사와 합병하여 GTT사가 되었음)가 개발한 또 하나의 멤브레인탱크로 탱크단면 형상은 Gas Transport type와 같고, 종방향, 횡방향으로 일정한 간격(340mm)으로 파형(corrugation)을 만들어 팽창 및 수축이 가능하게 한 1.2mm 두께의 스텐인레스(SUS) 304L의 멤브레인으로 일차방벽으로 구성되어 있다.Another membrane tank is another membrane tank developed by former Technigaz (now merged with GT and became GTT), and the tank cross-sectional shape is the same as the Gas Transport type, with constant intervals (340 mm) in the longitudinal and transverse directions. 1.2mm thick stainless steel (SUS) 304L membrane made of corrugation to allow expansion and contraction.

파형은 종방향의 것과 횡방향의 것이 교차하기 때문에 종방향의 것(large corrugation)이 횡방향의 것(small corrugation)보다 크며, 파형 형성시 가능한 잔류응력이 남지 않도록 특수하게 가공되고, 이렇게 만들어진 멤브레인은 열에 의한 수축 및 선체 변형을 자체적으로 흡수하게 된다.Since the corrugation crosses the longitudinal and transverse ones, the longitudinal corrugation is larger than the small corrugation, and is specially processed so that no residual stress is left when forming the corrugation. The silver itself absorbs heat shrinkage and hull deformation.

이차방벽은 수밀을 위한 알루미늄 포일(aluminium foil)에 보강하기 위한 유리섬유가 안팎으로 부착된 트리플렉스(triplex), 강화된 폴리우레탄폼 및 합판으로 구성된다.The secondary barrier consists of a triplex, reinforced polyurethane foam, and plywood with glass fibers attached in and out to reinforce aluminum foil for watertightness.

이러한 종래의 LNG 선 카고 탱크는 1 회 LNG 카고(Cargo)량을 증가시키기 위해 선박의 길이나 폭을 증가시켜 탱크 체적을 키우거나 새로운 추진 시스템을 적용하여 엔진 룸(Engine Room) 공간 등을 활용하여 카고량을 증가시키고 있거나 계획 중이다.This conventional LNG tanker cargo tank increases the length or width of the vessel to increase the amount of LNG cargo once, to increase the volume of the tank or to utilize the engine room space by applying a new propulsion system Cargo is increasing or planned.

본 발명의 목적은 1 회 LNG 카고량을 증가시키기 위하여 모스 형과 멤브레인 형을의 결합형태로 카고 탱크를 제작하는데 데크 하부는 멤브레인 형으로 제작하고 데크 상부는 반구형상의 모스 형으로 하여 탱크 용량을 크게 증가시키는 LNG 선의 카고 탱크 체적 증가 설계방법을 제공하고자 하는 것이다.An object of the present invention is to produce a cargo tank in a combined form of moss type and membrane type in order to increase the amount of LNG cargo once, the deck bottom is made of membrane type and the deck upper part is made of hemispherical moss type to increase the tank capacity. It is to provide a cargo tank volume increase design method of increasing LNG carriers.

3 : 멤브레인 형 탱크 4 : 모스 형 탱크3: membrane type tank 4: moss type tank

본 발명을 첨부된 도면을 참조하여 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings.

도3에는 본 발명의 따른 카고 탱크 구조가 도시되는데, 도면에는 LNG 선(1)이 개략적으로 도시된다.3 shows a cargo tank structure according to the invention, in which the LNG carrier 1 is schematically shown.

데크(2)의 하부에는 멤브레인 형 탱크(3)가 설치되고 멤브레인 탱크(3)위에는 반구형상의 모스 형 탱크(4)가 연통하게 설치된다.Membrane tank 3 is installed in the lower part of deck 2, and hemispherical MOS tank 4 is installed in communication with the membrane tank 3 above.

모스 형 탱크(4)는 멤브레인 형 탱크(3)의 상부에 얹힐 수 있는 크기를 가진다.The Morse tank 4 has a size that can be placed on top of the membrane tank (3).

모스 형 탱크(4)는 탱크 체적이 4/3πr3≒ 50,000 m3로 기타 체적 감소분 등을 고려하여도 대략 40,000 m3정도의 체적이 증가한다.In the Mohs type tank 4, the volume of the tank is 4 / 3πr 3 로 50,000 m 3 and the volume of about 40,000 m 3 increases even in consideration of other volume reductions.

따라서, 멤브레인 형 탱크 체적 138,000 m3에 모스 형 탱크 체적 40,000 m3을 더하면 총 체적 180,000 m3의 체적을 얻을 수 있다.Therefore, when the membrane type tank volume 138,000 m 3 is added to the Mohs type tank volume 40,000 m 3 , a total volume of 180,000 m 3 can be obtained.

한편, 탱크 체적이 증가함에 따라 발생될 수 있는 탱크 하중(Hydrostatic Pressure) 문제는 상하로 탱크를 분리시킬 수 있도록 한다.On the other hand, the problem of the tank load (Hydrostatic Pressure) that can be generated as the tank volume increases allows the tank to be separated up and down.

도4에는 본 발명의 다른 형태의 카고 탱크의 구조가 도시되는데, 종래의 멤브레인 형 탱크(10)위에 별도의 사각 박스형 탱크(11)를 부착하고 탱크(11)사이에는 단열 격실(12)이 위치한다.4 shows a structure of a cargo tank of another form of the present invention, in which a separate rectangular box tank 11 is attached to a conventional membrane tank 10 and an insulating compartment 12 is located between the tanks 11. do.

이러한 카고 탱크의 구조는 사각형 탱크(11)의 높이를 약 7 m 까지 제작할 수 있어 카고 탱크의 체적을 증가시킬 수 있다.The structure of such a cargo tank can produce a height of the rectangular tank 11 up to about 7 m can increase the volume of the cargo tank.

상기와 같이 구성된 본 발명의 LNG 선의 카고 탱크 체적 증가 설계방법에 따르면 기존 추진 시스템 또는 새로운 추진 시스템이라 하더라도 모스 형의 반구형상의 탱크를 기본 멤브레인 형 탱크와 결합하여 카고 탱크의 체적을 크게 증대시킬 수 있다.According to the cargo tank volume increase design method of the LNG carrier of the present invention configured as described above, even if the existing propulsion system or a new propulsion system, the volume of the cargo tank can be greatly increased by combining the moss-type hemispherical tank with the basic membrane tank. .

상기와 같은 본 발명의 LNG 선의 카고 탱크 체적 증가 설계방법에 따른 카고 탱크를 가지는 LNG 선은 1 회 LNG 카고량을 증가시켜서 선박 수주 증가 및 가격 상승 효과를 얻을 수 있다.The LNG carrier having a cargo tank according to the cargo tank volume increase design method of the LNG carrier of the present invention as described above may increase the amount of LNG cargo once and obtain an increase in ship orders and a price increase effect.
