I did a Google search to see what it looks like. I am also attaching what I got to make sure that we are on the same page. To design something like attached below, you need to have the operating weight of the machine and pipe-stress analysis report that provides you with stress loads at each location where the pipe is located. You need to make sure that the structure is designed for wind drift less than H/200 and seismic drift less than the applicable code. These structures are very common in EPC Industry. Normally, the vendor provides the maximum operating, empty and hydro test weights along with max shears due to wind and seismic. Ask your vendor for this information and proceed with design.
Please post your follow up questions.
Thanks.
