I don't think anyone can help you with that on this forum.
Get a local consultant.

Detailing is a hobby,

Usually the tank constructor will have their own method.

In short, what normally happens is
1) Weld a bunch of columns to the floor plate and make an internal structure
2) Weld a bunch of supports to the tank wall
3) Install hydraulic rams between the two and lift

There is obviously a bunch of design that must be done, but this is the basic process


The only other way to do it is replace is small sections, including some of the bottom strake, e.g do 3-5 metres at a time, cut our the bottom strake, replace ring + bottom strake, move to next section and repeat.
