Substantially rectangular-shaped tanks are provided for storing liquefied gas, which tanks are especially adapted for use on land or in combination with bottom-supported offshore structure such as gravity-based structures (GBS). A tank according to this invention is capable of storing fluids at substantially atmospheric pressure and has a plate cover adapted to contain fluids and to transfer local loads caused by contact of said plate cover with said contained fluids to a grillage of stiffeners and stringers, which in turn is adapted to transfer the local loads to an internal truss frame structure. Methods of constructing these tanks are also provided.

I claim: 1. A method of constructing a fluid storage tank having a substantially rectangular-shaped, internal truss frame structure, said method comprising: (A) providing a plurality of plates, a plurality of stiffeners and stringers, a plurality of first truss frame elements, and a plurality of second truss frame elements; (B) forming plate covers from one or more of said plurality of plates; (C) joining a portion of said plurality of stiffeners and stringers to a first side of said plate covers; (D) joining a portion of said plurality of first truss frame elements to said first side of a plate cover, thereby forming a panel element comprising a side wall portion of an internal truss frame structure; (E) joining a portion of said plurality of second truss frame elements to said first side of a plate cover, thereby forming a panel element comprising an end wall portion of said internal truss frame structure; (F) repeating steps (B) through (E) to form a plurality of panel elements; (G) forming a plurality of tank modules from said plurality of panel elements; (H) assembling said plurality of tank modules along with a tank top and a tank bottom to form a fluid storage tank with two tank side walls, two tank end walls, and a substantially rectangular-shaped truss frame structure comprising: (i) a first plurality of truss structures extending transversely and longitudinally-spaced from each other along the length direction of said internal truss frame structure such that said first plurality of truss structures are (a) spaced from said two tank end walls and (b) in contact with said tank top, said tank bottom, and said two tank side walls; and (ii) a second plurality of truss structures extending longitudinally and transversely-spaced from each other along the width direction of said internal truss frame structure such that said second plurality of truss structures are (a) spaced from said two tank side walls and (b) in contact with said two tank end walls, said tank top, and said tank bottom; wherein said first plurality of truss structures and said second plurality of truss structures are interconnected at their points of intersection and each of said first and second plurality of truss structures comprises: (1) a plurality of both vertical, elongated supports and horizontal, elongated supports, connected to form a gridwork of structural members with a closed outer periphery, and (2) a plurality of additional support members secured within and between said connected vertical and horizontal, elongated supports to thereby form each said truss structure. 2. The method of claim 1, wherein said plurality of stiffeners and stringers are arranged in a substantially orthogonal pattern, interconnected and attached to the peripheral external extremities of said substantially rectangular-shaped, internal truss frame structure, said stiffeners and stringers are in substantially the vertical and horizontal directions respectively, or in substantially the horizontal and vertical directions respectively, wherein said tank is capable of storing fluids at substantially atmospheric pressure and said plate cover is adapted to contain said fluids and to transfer local loads caused by contact of said plate cover with said contained fluids to said plurality of stiffeners and stringers, which in turn is adapted to transfer said local loads to said substantially rectangular-shaped, internal truss frame structure. 3. The method of claim 1, further comprising transporting said plurality of tank modules from a first location to a second location and then assembling said plurality of tank modules to form a fluid storage tank. 4. A method as claimed in claim 1, further comprising forming a plurality of top panels, a plurality of side panels, and a plurality of bottom panels. 5. A method as claimed in claim 4 wherein said forming step (G) includes forming tank mid section modules and tank end section modules. 6. A method as claimed in claim 5 wherein said forming step (G) includes joining one said bottom panel to first ends of two said side panels, joining one said top panel to second ends of said two side panels, thereby forming a tank mid-section module comprising a portion of said internal truss frame.
