The common characteristic of LNG Storage tanks is the ability to store LNG at the very low temperature of -162 °C (-260 °F). LNG storage tanks have double containers, where the inner contains LNG and the outer container contains insulation materials. The most common tank type is the full containment tank. [1] Tanks vary greatly in size ...
The Code also sets out requirements for emergency shutdown (ESD) systems for when liquefied gas cargoes are carried in bulk. [4] Section 4.1 of the IGC Code defines several types of tanks that can carry liquefied gases. These include independent tanks (of which there are three types, A, B and C), membrane tanks, integral tanks and semi-membrane ...
LNG for use as a fuel, as seen on this LNG bunkering vessel is regulated by the Code. The IGF Code provides industry standards for ships that use fuels with a flashpoint of less than 60°C. The IGF Code seeks to regulate the safety changes from the carriage and use of gas fuel, in particular liquefied natural gas and other low-flashpoint fuels.
The major design codes for welded atmospheric tanks are API 650 and API 620. API 653 is used for analysis of in-service storage tanks. In Europe the applicable design code is EN 14015, which uses load cases from Eurocode 3 (EN 1993), part 4-2.
LNG storage tank at EG LNG. Modern LNG storage tanks are typically of the full containment type, which has a prestressed concrete outer wall and a high-nickel steel inner tank, with extremely efficient insulation between the walls. Large tanks are low aspect ratio (height to width) and cylindrical in design with a domed steel or concrete roof.
All piping connected to the LNG tanks, whether above ground or in-ground, are routed through the top of the vessel. This militates against loss of containment in the event of a piping breach. Tanks may be situated within a bund wall to contain the LNG in the event of a rupture of the tank. [13]
LNG storage tanks possess a number of advantages over underground storage. As a liquid at approximately −163 °C (−260 °F), it occupies about 600 times less space than gas stored underground, and it provides high deliverability at very short notice because LNG storage facilities are generally located close to market and can be trucked to ...
A Horton sphere (sometimes spelled Hortonsphere), also referred to as a spherical tank or simply sphere, is a spherical pressure vessel, which is used for industrial-scale storage of liquefied gases. Example of materials that can be stored in Horton spheres are liquefied petroleum gas (LPG), liquefied natural gas (LNG), and anhydrous ammonia .
