Disclosed is a liquid container adapted to store liquefied natural gas (LNG). The LNG storage container include a sealing wall directly contacting liquid contained in the tank and a structural wall, which is an exterior wall or inner structure integrated with the exterior wall. The container further includes a plurality of connectors mechanically connecting the sealing wall and the structural wall and an intermediate wall structure positioned between the structural wall and the interior wall. The intermediate wall structure is configured to move relative to at least one of the interior wall and the structural wall.

What is claimed is: 1. A method of building a liquid container, comprising: providing a structural wall, an intermediate wall structure, a sealing wall and a plurality of elongated anchors, each elongated anchor having a first end portion, a middle portion and a second end portion along a longitudinal direction thereof, the middle portion located between the first and second end portion, the intermediate wall comprising a first surface and a second surface; placing the intermediate wall structure on the structural wall such that the second surface contacts the structural wall, wherein the intermediate wall structure comprises a first insulating layer, a second insulating layer and a sealing layer located between the first and second insulating layers; connecting the first end portion of the anchor with the structural wall; placing the sealing wall such that the intermediate wall structure and the anchor are interposed between the structural wall and the sealing wall and such that the first surface contacts the sealing wall; connecting the second end portion of the anchor with the sealing wall; liquid-tightly connecting a sealing plate with the middle portion of the anchor, wherein the sealing plate extends from the middle portion generally in a plane substantially perpendicular to the longitudinal direction; and liquid tightly coupling the sealing plate and the sealing layer of the intermediate wall structure using a coupler, whereby the sealing layer of the intermediate wall is liquid-tightly connected with the anchor; wherein the coupler comprises a first piece and a second piece, and wherein a portion of the sealing plate is interposed between the first piece and the second piece. 2. The method of claim 1, wherein the liquid container comprises a ship, and wherein the structural wall comprises an exterior wall or an interior wall of the ship. 3. The method of claim 1, wherein the first surface of the intermediate wall structure is not attached onto the sealing wall while the first surface of the intermediate wall structure contacts the sealing wall. 4. The method of claim 1, wherein the intermediate wall structure is movable relative to the structural wall. 5. The method of claim 1, wherein connecting the first end portion comprises attaching the first end portion to the structural wall such that the anchor is substantially non-movable relative to the structural wall. 6. The method of claim 1, wherein connecting the second end portion comprises attaching the second end portion to the sealing wall such that the anchor is substantially non-movable relative to the sealing wall. 7. The method of claim 1, wherein connecting the first end portion of the anchor comprises: placing the anchor next to the intermediate wall structure such that the first end portion thereof faces the structural wall; and attaching the first end portion of the anchor to the structural wall such that the longitudinal direction thereof is substantially perpendicular to the structural wall. 8. The method of claim 7, further comprising liquid-tightly connecting the anchor with the intermediate wall structure. 9. The method of claim 7, further comprising connecting the anchor to the intermediate wall structure such that the intermediate wall structure is allowed to move relative to the anchor. 10. The method of claim 1, wherein the sealing plate comprises at least one corrugation configured to allow extension and shrinkage thereof in a direction generally in the plane substantially perpendicular to the longitudinal direction of the anchor. 11. A liquid container produced by the method of claim 1, wherein the anchor is located in a through hole formed in the intermediate wall structure. 12. The method of claim 1, wherein the portion of the sealing plate comprises a wrinkle which comprises a first surface and a second surface opposing the first surface, and wherein the first piece contacts the first surface of the sealing plate and the second piece contacts the second surface of the sealing plate. 13. The method of claim 1, wherein a portion of the sealing layer is interposed between the first and second pieces. 14. The method of claim 13, wherein the portion of the sealing layer comprises a wrinkle which comprises a first surface and a second surface opposing the first surface, and wherein the first piece contacts the first surface of the sealing layer and the second piece contacts the second surface of the sealing layer. 15. The method of claim 1, wherein the first surface of the intermediate wall structure is movable relative to the sealing wall. 16. The method of claim 1, wherein the second surface of the intermediate wall structure is movable relative to the structural wall. 17. A method of building a liquid container, comprising: providing a structural wall, an intermediate wall structure, a sealing wall and a plurality of elongated anchors, each elongated anchor having a first end portion, a middle portion and a second end portion along a longitudinal direction thereof, the middle portion located between the first and second end portion, the intermediate wall comprising a first surface and a second surface; placing the intermediate wall structure on the structural wall such that the second surface contacts the structural wall, wherein the intermediate wall structure comprises a first insulating layer, a second insulating layer and a sealing layer located between the first and second insulating layers; connecting the first end portion of the anchor with the structural wall; placing the sealing wall such that the intermediate wall structure and the anchor are interposed between the structural wall and the sealing wall and such that the first surface contacts the sealing wall; connecting the second end portion of the anchor with the sealing wall; and liqiuid-tightly connecting a sealing plate with the middle portion of the anchor, wherein the sealing plate extends from the middle portion generally in a plane substantially perpendicular to the longitudinal direction, wherein the sealing plate is liquid tightly connected with the sealing layer of the intermediate wall structure, whereby the sealing layer of the intermediate wall is liqiuid-tightly connected with the anchor, wherein placing the intermediate wall structure comprises: placing a first wall module on the structural wall; placing a second wall module on the structural wall and next to the first wall module; and connecting the first and second wall modules to form the intermediate wall structure. 18. A liquid container produced by the method of claim 17, comprising a ship, wherein the structural wall comprises an exterior wall or an interior wall of the ship.
