Real World Examples

LNG storage tanks in practice – single, double, full containment, and membrane designs

Implementation: Dr. Ahmed Abdelfattah Helmi of the LNG Transportation and Storage lecture series confirmed that all field-erected LNG storage tanks have a primary and a secondary containment system where the primary container is for normal operation and the secondary containment is for the highly unlikely event of a leak in the primary container and that worldwide a variety of storage tank types have been developed and constructed including single containment types with a cylindrical metal primary tank and earthen dike wall secondary containment now used mainly in remote locations and double containment types with a cylindrical metal primary tank and independent metal or reinforced concrete open top secondary containment outer tank and full containment type tanks with a cylindrical metal inner primary tank and metal or pre-stressed concrete outer secondary containment tank structurally independent but combined into one structure. Korea Gas Corporation KOGAS confirmed in 2005 that they developed the largest above-ground full containment LNG storage tank in the world with a gross capacity of 200,000 m³ with the inner tank manufactured with 9 percent nickel steel and the outer tank composed of reinforced concrete and pre-stressed concrete and that according to BS 7777 specifications LNG tanks are classified in three different types where a full containment tank is described as a double tank designed and constructed so that both the inner tank and the outer tank are capable of independently containing the refrigerated liquid stored and that the difference between double containment and full containment is that the outer tank of a full containment tank is intended to be capable of both containing the refrigerated liquid and controlled venting of vapor resulting from product leakage after a credible event. Full containment membrane tanks with a cylindrical thin metal membrane primary container structurally supported by an outer pre-stressed concrete cylindrical tank where the outer concrete tank also serves as the secondary leak containment have found application particularly in Japan and Korea with in-ground membrane tanks regularly built below grade where the outer wall is held in compression by soil pressure, with the approximate worldwide field-erected LNG tank distribution confirming 320 single containment and 15 double containment and 110 full containment and 30 membrane containment and 50 membrane in-ground containment tanks, directly reflecting the tank typology and safety logic taught in the course’s module on types of LNG storage tanks.​

Results: The KOGAS 200,000 m³ full containment LNG storage tank case study confirmed that the tank design incorporates a bottom heating system using ethylene glycol as brine fluid to avoid frost heave and that the boil-off gas acts to keep the LNG cold and is typically compressed and exported as natural gas or re-liquefied and returned to storage and that storage pressure in these tanks is very low at less than 10 kPa and that LNG must be kept cold to remain a liquid independent of pressure and that despite efficient insulation there will inevitably be some heat leakage into the LNG resulting in vaporization, demonstrating that LNG plant operators who understand full-containment tank design and 9-percent nickel steel inner tank cryogenic service requirements and boil-off gas management and bottom heating system operation are materially better equipped to maintain safe and efficient LNG storage operations. Results confirmed that the capital cost of constructing an in-ground LNG tank is over twice that of a full containment tank and that in-ground tanks consume more electrical energy for increased boil-off compression and soil and foundation heating and ground water pumping at approximately a constant 1,500 kW additional load, illustrating exactly the types of LNG storage tanks and aspects of maintenance and equipment components and success factors of LNG development knowledge the course builds through its modules spanning the full LNG plant operations competency framework.​

LNG hazards in real facilities – brittle fracture, RPT, rollover, and fires

Implementation: Pushp Khetarpal of PETRONET LNG Limited confirmed that LNG spilled on ground results in fast evaporation on first contact with soil with cold vapor denser than air and the gas cloud dispersing into the atmosphere as it warms up and that on water due to convection the evaporation rate remains constant and high with the white visible cloud being condensation of water vapor while natural gas is colorless and that at temperature above minus 80 degrees Celsius natural gas becomes lighter than air, with the FIPI hazards presentation further confirming that brittle fracture causes sudden brittle rupture of non-cryogenic materials and that direct contact with LNG jet stream of vapors containing liquid droplets is worse than direct contact because they magnify heat transfer and make freezing potential significantly worse and can spread to a larger area and that contact with cold metal surface can cause adhesion of the skin with flesh torn when skin is removed from the metal. The Port of Rotterdam and Falck RISC and Unified Fire Department Rotterdam Rhine-Main-Danube emergency response study confirmed that LNG is stored at very low temperature of approximately minus 162 degrees Celsius and that any contact with carbon steel will lead to brittle fractures and that skin contact will result in severe burn injuries and that LNG is a constantly boiling liquid kept stable by constantly boiling off the cargo and that during a cargo transfer excessive BOG is generated and must be handled and that hazardous areas are to be determined and classified with LNG having approximately 50 percent of energy density of MDO and clear benefits in reducing pollution. Pushp Khetarpal of PETRONET LNG further confirmed that rollover is caused by rapid mixing of stratified layers where superheated liquid flashes releasing large quantities of gas over a short period and that high nitrogen content in LNG can also cause rollover and that rollover prevention requires limiting allowable amount of nitrogen in LNG and tank management through top and bottom filling and boil-off rate monitoring and density profile monitoring and liquid mixing through recirculation and tank-to-tank transfer and send-out rate and that rapid phase transition is a physical explosion with no combustion confirming the real-facility rollover and RPT hazards the course addresses in its modules on types of LNG storage tanks and major LNG hazards and aspects of maintenance.​​

Results: The Port of Rotterdam Rhine-Main-Danube study confirmed that firefighting strategy for LNG scenarios uses dry chemical extinguishing and that extinguishing is not always necessary for gas cloud and LNG pool because re-ignition can occur and that water should never be used on LNG and that the event tree for a release of LNG at near atmospheric pressure and the event tree for a release of LNG at increased pressure and the event tree for fires other than LNG provide organizations with comprehensive consequence modeling tools using PHAST modeling schematics and DEGADIS dense gas dispersion model and LNGFIRE3 thermal radiation model and SOURCE5 vaporization rate and pool radius prediction, confirming that LNG plant operators trained in major LNG hazards and ignited leaks emergency response and transfer operations and aspects of maintenance can respond more effectively and protect people and equipment and the environment. Results confirmed that the Cleveland 1944 LNG disaster where most deadly accident in US resulted in 130 fatalities and more than 700 homeless led directly to development of LNG-specific codes including strict specifications for material of construction for low temperatures and spill handling and containment and restrictions on layout for protection of the public and that subsequent codes including 49 CFR 193 and NFPA 59A governing LNG facilities cover siting requirements and design and construction and equipment and operation and maintenance and personnel qualification and training and fire protection and security, illustrating exactly the gas policy and regulatory framework and types of LNG storage tanks and major LNG hazards and aspects of maintenance and environmental impacts of LNG facilities knowledge the course builds through all 12 of its comprehensive modules.​​
