Abstract (en)

Disclosed is a concrete tank for very large LNG tanks . The invention utilizes membrane technology in concrete structures that deviate from the standard cylindrical constructions. Typical concrete housings of the invention are a parallelepipedic structure, or an annular structure comprising two concentric walls. Both structures can be covered by a gabled or an arched roof, and avoid the size limitations imposed on cylindrical structures as a result of the size limitations inherent to concrete domes. The invention proposes also several ways to improve the available working height of LNG within such concrete structures of a given height.
