Thank you @ IFR's
presence and locations of float lines on the pontoons, visible in an out-of-service inspection.
The float lines are normal. All the floats are 50% submerged. This is why the doubt occurs that how the product is oozing over the deck?(observation of stain marks)
Self-drilling...
Thank you @LittleInch.
I've never seen Kl/hr before - 600 m3/hr? what size pipe and velocity?
Yes. It is 600 m3/hr. The inlet size is 12" and its velocity is around 2.3 m/s.
How is the roof monitored/operated when it gets to low level / sat on legs?

Hi all.
In an aluminium geodesic dome, after erecting the last ring of the dome we have only 80mm gap between the tank shell and the edge of the bottom node of the last ring. we couldn't even fix the top node of the last ring. We have erected this dome inside a 30 m dia tank and we have planned...
