Steel Tank Evaluation using FEA

Marine Solutions recently evaluated a 42-foot diameter, 33-foot tall steel storage tank.  Our team was tasked with developing a 3D finite element model to determine how the tank would perform under high wind conditions after two new 3’x7’ wall openings were cut into the tank wall.

Because of the tank’s size and geometry, finite element analysis (FEA) was the ideal method for accurately predicting stress levels throughout the tank wall. The tank’s wall thickness varied from 3/16" at the base to 3/32" at the top, making it especially vulnerable to buckling under compression. Cutting new openings in the tank wall further increased compressive stresses in the surrounding areas.

Our analysis revealed that reinforcing steel angles would be required around the new openings to maintain the tank’s structural stability.

A standout feature of this project was the quick turnaround time. Our team developed the 3D model, performed the analysis, and delivered results to the client in less than one week, keeping the project moving without disruption to the project schedule.

We’re grateful to our client for the opportunity to support them on this unique and fast-paced project.
