Abstract:
A tank for transport and/or storage of cryogenic gases especially for LNG (Liquefied Natural Gas) where the tank consists of an outer tank, loadbearing insulation and an inner tank that is made of a flexible plate/sheet material which have an expansion coefficient that does not affect the tanks construction even the temperature differences inside the tank could be over 200 C°. The plate/sheet material has tear drop patterns/corrugates of aluminium or another similar cold resistant metal.

Abstract:
The present invention provides a method for increasing the internal pressure of a pressure vessel (1) containing a medium being present in both a liquid (3) and gaseous (2) phase, the vessel comprising one inner(9)and one outer(10) fluid tight barrier, said barriers being separated by an inter-barrier space (8), comprising the steps of: -circulating a suitable fluid through both the inter-barrier space and a heating unit; and -heating the fluid by the heating unit.
Abstract:
The present invention relates to a ship or floating support (1) for transporting or storing the liquid consisting of a liquefied gas, preferably chosen from methane, ethylene, propane and butane, cooled in a large tank, preferably a cylindrical one with polygonal cross section, which is thermally insulated and very large with at least its shortest dimension in the horizontal direction, notably its width, greater than 20 m and preferably ranging from 25 to 50 m, and a volume in excess of 10 000 m3, characterized in that said tank is equipped with at least one device for attenuating the movements of said liquid comprising means of displacing said liquefied gas liquid within said tank to form a horizontal current just below the free surface of said liquefied gas at least locally to a depth of at least 0.5 m, preferably at least 2 m.
Abstract:
본 발명은 주름이 종방향과 횡방향으로 형성되어 서로 교차되는 저온 유체 저장 탱크의 금속 멤브레인에 있어서, 주름의 교차 부위에 종방향 및 횡방향으로 신축이 가능하도록 주름 각각이 연결되는 양방향 신축부가 형성되고, 양방향 신축부가 돌출된 피라미드 형상, 돔 형상 또는 십자 형상을 가진다. 따라서, 본 발명은 상온에서 각 단위 금속 멤브레인이 단열패널에 용접에 의해 고정되고, 또한 화물창 전제의 기밀을 위하여 각 단위 금속 멤브레인이 이웃하는 다른 금속 멤브레인의 가장자리에 겹치기 용접에 의해 서로 연결되는 구조를 가지는 화물창 내부에 극저온의 LNG를 저장함으로써 금속 멤브레인이 큰 온도 차이로 인해 수축할 때 용접부에 발생하는 응력을 저감시키기 위해 면강성을 감소시키면서 동시에 직교하는 양방향 면강성이 동일하도록 함으로써, 극심한 온도차를 겪게 되더라도 내구성을 증대시킴과 아울러 기밀성을 유지하도록 하고, 안정적인 저온 유체의 저장을 가능하도록 하며, 용접 로봇이나 이송 장치의 클램핑 수단에 의해 쉽게 클램핑될 수 있도록 함으로써 저장 탱크 제조 작업의 효율을 높이도록 하는 효과를 가지고 있다.
