Proven Concrete Technology for Safe and Reliable LNG Storage
All-precast concrete tanks for the storage of LNG were designed and constructed by Preload dating back to the 1960s, and several tanks have been in continuous service for more than 40 years, demonstrating the durability and longevity of such tanks. The C3T design takes advantage of the experience from concrete LNG tanks built before 1980 that are still in service today. Furthermore, the design follows the newest applicable codes by American Concrete Institute (ACI) and American Petroleum Institute to meet National Fire Protection Association (NFPA) 59A.
Over the past 10 years, under the leadership of BergerABAM, a joint-industry project with partners from major energy companies and contractors further developed the all-precast concrete tank technology to be fully compliant with modern codes and applicable for a wide range of storage volumes from 10,000 to 300,000 cubic meters.
The tank design was subjected to a rigorous technology qualification program and received a “Technology Certi cate” from GL-DNV. All-precast concrete tanks are a proven technology for safe and reliable LNG storage.
Clear Pathway through Regulatory Filing and Review
The Federal Energy Regulatory Commission (FERC) and the Pipeline and Hazardous Material Safety Administration (PHMSA) are familiar with the C3T design and together, Preload and BergerABAM established a clear pathway to get a tank through regulatory ling without delay. Following a three- month review of a typical tank design and a code comparison study, PHMSA issued a letter stating that it “...has no objection to the use of precast all-concrete storage tanks, provided that they are designed, fabricated, and constructed according to the ACI 376 standard.”
01 - Two 143,000-m3 full-containment LNG tanks for Distrigas in Staten Island, New York. Successfully hydrotested; never placed in service.
02 - Two 95,000-m3 double-containment LNG tanks for Philadelphia Gas Works built in 1974 and still in service today.
03 - An 80,000-m3 LNG tank for ENAGAS in Barcelona, Spain, and still in service today.
