An LNG full containment system is provided. The LNG system generally comprises a primary container, and a secondary container positioned around the primary container. The secondary container generally comprises a first end wall, a second end wall, and at least two side walls. At least one of the walls is fabricated from a plurality of prefabricated wall panels. Each of the wall panels is fabricated from a combination of concrete and steel. The wall panels are preferably prefabricated offsite, and then transported to the construction site where they are adjoined together in end-to-end fashion to form walls. A method for constructing a full containment LNG system is also provided. In one embodiment, walls and a roof for a secondary container are assembled, but leaving an end open. At least one primary tank is brought into the secondary container. A second end wall is then erected to form the enclosure for the secondary container.

What is claimed is: 1. An LNG full containment system, comprising: a floor slab; a primary container positioned on the floor slab, the primary container being insulated to hold liquefied natural gas; and a secondary container peripherally positioned around the primary container, the secondary container comprising a plurality of composite walls attached to the floor slab, with each of the composite walls being formed from a plurality of prefabricated wall panels configured to be adjoined in side-to-side fashion; and wherein each of the prefabricated wall panels is formed from a combination of steel and concrete such that the prefabricated wall panel comprises: a concrete plate having a longitudinal axis and an outer surface, and at least one steel beam connected to the outer surface of the concrete plate along the longitudinal axis of the concrete plate. 2. The LNG full containment system of claim 1, wherein the plurality of composite walls of the secondary container comprises: a first end wall; a second end wall; and at least two side walls, with each of the at least two side walls being disposed on opposing sides of the first end wall. 3. The LNG full containment system of claim 1, wherein each of the prefabricated wall panels further comprises: a moisture barrier disposed on the concrete plate opposite the at least one steel beam. 4. The LNG full containment system of claim 3, wherein each of the prefabricated wall panels further comprises: an insulation layer along the moisture barrier opposite the at least one steel beam; and a liner plate on the insulation layer. 5. The LNG full containment system of claim 3, wherein the moisture barrier is fabricated from material selected from the group consisting of: a metallic material and a polymeric material. 6. The LNG full containment system of claim 1, further comprising: a roof structure, the roof structure comprising a plurality of prefabricated roof panels adjoined in side-to-side fashion, each of the roof panels comprising: a concrete plate having an inner surface, and a steel truss structure under the inner surface of the concrete plate. 7. The LNG full containment system of claim 1, wherein: the plurality of composite walls of the secondary container comprises: a first end wall; a second end wall; and at least two side walls, with each of the at least two side walls being disposed on opposing sides of the first end wall; each of the prefabricated wall panels comprises: a moisture barrier disposed on the concrete plate opposite the at least one steel beam, an insulation layer along the moisture barrier, and a liner plate on the insulation layer; and the secondary container further comprises a roof structure, the roof structure comprising a plurality of prefabricated roof panels adjoined in side-to-side fashion, each of the roof panels comprising: a concrete plate having an inner surface, and a steel truss structure under the inner surface of the concrete plate.
