Dear Experts,

I have attached a measurement taken, by dropping a plump-bob from top of the tank, on top and bottom of the individual strake to check the plumpness of individual courses. Top course is 1800mm heigh and the rest is 2400mm heigh and of 8mm thick. Tensile Strength of the plates are 450MPA.I want to check with you all if this tank is with in the acceptable tolerance limits?
