Why Choose C3T

A Robust, Full-Containment Storage Solution for Refrigerated Gases

The composite concrete cryogenic tank (C3T) provides full-containment storage for refrigerated and cryogenic liquids, such as LNG, LOX, LPG, ethylene, ammonia, etc..

Robust Concrete Walls Provide Price Stability over Conventional Nickel Tanks

The C3T is constructed of prefabricated wall modules that are integrated to build strong liquid and gas-tight monolithic primary and secondary containment walls. The walls are designed to maximize the use of conventional construction materials, such as concrete, post-tensioning strand/wire, and carbon steel, to minimize the use of the costly and volatile 9 percent nickel steel (9% Ni).

Modular Construction to Reduce On-Site Construction Cost and Risk

The modular construction of the C3T utilizes wall elements that are prefabricated o site, significantly reducing on-site labor and increasing the quality of the wall construction. Modular construction also reduces the on-site construction schedule, reduces the environmental impact during construction, enhances construction safety, and opens construction to a wider labor market.

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.”
