Large vertical storage pressure vessel

A storage tank with a diameter of 12,000 and a cylinder length of 30,000 is to be designed, supported by a skirt foundation, for storing C4 liquefied hydrocarbons. Is it feasible in accordance with the design codes for pressure vessels and tower equipment? Who has experience using a similar design? Thank you first!
The length-to-diameter ratio is less than 3; I’m not sure how to approach this.
Refer to pressure vessel? The operating parameters need to be made public so that it’s possible to determine whether it’s feasible; I wonder what the reasoning was behind using such a short and bulky container

Does the calculation model for the tower skirt match yours?
C4 liquefied hydrocarbon, design pressure 0.28 MPa, design temperature 34°C, corrosion margin 2 mm. The design itself meets the specifications, and I would like to seek advice from those with experience in design and construction.
The nominal thickness of the equipment’s cylinder is about 24 mm, and its length-to-diameter ratio is significantly smaller than that of a tower; however, I suppose there shouldn’t be any difference in the stress calculations for the critical sections. Please point this out.
Thank you all for your active responses and support.
This device can only be manufactured on-site. Are the length and diameter fixed? I always think it’s unreasonable. Haha!
It is a measure taken due to constraints; spherical tanks represent a reasonable choice, offering resistance to both positive and negative pressures, good stiffness, as well as numerous proven examples of their use in engineering projects.
Based on the parameters you provided, it is unreasonable to use vertical cylindrical storage tanks; spherical tanks are the only suitable option.
