Finite Element Analysis (FEA)

Typical Applications

We perform FEA for a wide range of industrial applications, including:

• Local stress assessment on critical details (connections, brackets, reinforcements)
• Skid frames and modular structures (local/global stiffness verification)
• Flare system components and accessories (platforms, supports, attachments)
• Nozzles, shells, and discontinuities on vessels and piping interfaces
• Base plates, anchor regions, and welded/bonded details
• Complex components subject to combined mechanical and thermal loads

Main Analysis Capabilities

Depending on project requirements, we develop and verify:

• Static analysis for stress and deformation under operating and accidental loads
• Thermo-structural analysis to evaluate stresses induced by temperature variations and thermal gradients
• Buckling analysis for slender or compression-loaded components
• Fatigue assessment for cyclic loads and long-term reliability of critical details
• Local stress evaluation for nozzles, junctions, and discontinuities, aligned with code methods and recognized references (e.g., WRC bulletins where applicable)

Engineering Workflow

Our FEA workflow is structured to ensure traceability and reliable results:

• Definition of scope, boundary conditions, and load cases
• Geometry preparation and modelling strategy (global vs local models)
• Meshing and convergence checks where required
• Result interpretation and verification against code criteria
• Design optimization and practical recommendations for fabrication and installation

Software Tools

Techso Engineering performs FEA using professional analysis platforms, including:

• Midas Gen
• Autodesk Inventor Nastran
• Other dedicated FEA solvers as required by project specifications

Deliverables

Typical deliverables include:

• FEA report with modelling assumptions, load cases, and results
• Stress / deformation maps and critical section checks
• Buckling factors and stability verification (when applicable)
• Fatigue summary and recommended design improvements (when applicable)
• Clear design recommendations for workshop execution and site installation

Value for the Project

FEA is not only a verification tool: it supports design decisions by reducing uncertainties, improving constructability, and preventing costly modifications during fabrication and installation.

Techso Engineering delivers FEA services as part of an integrated engineering approach, coordinated with structural design, piping stress analysis, and 3D modelling, ensuring consistent and implementable solutions.
