Fig. 3 Schematic top view of platform on the vessels
cement concrete (RCC) plinth and grounded with foundation bolts. The center pipe
with welded treads over it fixed and welded to the foundation plate forms a spiral
ladder. The platform structure comprises of bridge type structure which joined with
existing inbuilt extended platform of vessels. A common platform is a way to all four
vessels assembled with spiral ladder top plate. Railing piping and angle support is
provided up to appropriate height in spiral ladder and common platform structure for
ease and safety of working personnel. The cantilever effect mitigated of spiral ladder
structure by installation of the stiffener supports in form of C-channel and angle to
the center pipe of ladder. Due to working environment in open atmosphere and rainy
seasonal aspects, mild steel structure of grade 2062 with hot dipped galvanizing ENI
461 (50–60µ) coating was applied. The foundation of structure and elements lifting
and assembly of structure by crane are shown in Figs. 4 and 5 respectively.
5 Mechanical Analytical Analysis of Structure
The mechanical analysis [5] of each elements of structure has been carried out for
optimization of material, safe loading, failure aspects and environmental effects.
