Hi Guys,
We are erecting two tanks about 6450 mm (254 in) high at the top of shell (i.e top rim, not roof height), edge to edge distance about 1.9 m (75 in) b/w the two tanks. So we have 2 independent rest platforms rectangular at the top of shell on the outside of the tank (i.e not on the roof, but at the edge of the top of topmost strake of tank). There is a gap of 300 mm b/w the two platforms. A stairway leads up one of them. To make the platforms common we will overlay a 5mm chequered plate about 500mm long between the two platforms and over the gap. It (plate) is to be bolted down at both ends. The design has been certified by a senior engineer.
But I have my reservations. For one the tanks are in a cyclonic region. Another even if the tanks deflect within design limits want they basically pull each other due to the common linkage thru the common platform.
So could someone shed some light on this design, like does it appear to be safe, or give some alternative suggestions. I am thinking of just not bolting one end of the chequered plate. Is that a good solution.
Look forward to your replies.
