The size of the tanks can now be appreciated, with the diminutive figures of the construction team standing around the top perimeter walkway giving a good perspective.
The walls of the tank are reinforced concrete, the dome of the roof is constructed from steel plates and beams.
The steel dome is constructed and welded down on the ground floor of the tank. Once complete and fully welded, air is then blown nto the bottom of the tank, as the air pressure builds the steel dome rises up the inside of the tank. After about 12 hours, the steel dome hits the top of the tank and is quickly pinned and welded in place.
The steel dome's only function is to provide a mould for the concrete that is poured onto it. Once the concrete has set, the steel dome has completed its task, it's too time consuming and expensive to remove the steel work afte the concrete has formed, therefore, it's left in place for the lifetime of the tank.
Congratulations to our Whessoe team of civil, structural and mechanical engineers for another great design and congratulations to our colleagues in the Samsung C&T team for all their hard work on the project.
