A liner has lifting straps that are lifted by winch booms connected to booms. Exterior securing straps are used to hold the liner in place. Connecting plates are secured to trunnions on each of the panels. Pressure pins allow the connector plates to flex so that the panels can form a round or oval tank. The panels are constructed in a curved fashion to create the round or oval tank wall.

providing curved panels that have a panel box located on a panel at a location proximate to a center of gravity of said panel;
securing a panel box attachment to a boom, said panel box attachment configured to attach to said panel box;
lifting said curved panels one at a time and placing said curved panels in a rounded tank wall;
attaching said curved panels to each other using connector plates that are placed over trunnions attached to said curved panels using pressure pins inserted through openings in said trunnions.
2. The method of claim 1 wherein said panel box is formed from structural members of said curved panels and have openings that align with pins on said panel box attachment.
