LNG Tank - An inside view before the inner liquid tank begins..

The suspended deck is raised with the steel roof dome during the airlift.

The concrete floor has multiple layers of insulation added to protect the LNG from heat ingress from the ground.

The inner concrete walls are then lined with hundreds of steel plates that are welded to the tank wall and with each other to form a perfectly sealed vapor barrier.

Quite a sight ! The inner tank hasn't even started yet, so bring back the welders.
