Finite Element Analysis for Pressure-Control Equipment

Structural, thermal and pressure-boundary analysis for design validation, qualification and re-rating — with reports written to survive review by your own engineers and, where required, a third party.

What we cover

Pressure-boundary Stress Analysis

Design verification of pressure-containing components against allowable stress limits to API 6A, 6X, 17D for wellhead, valve and subsea equipment.

Elastic-plastic and limit-load analysis

Where linear-elastic results are too conservative to qualify a design — plastic collapse, local failure and limit-load assessment.

Fatigue and cyclic life

Pressure and thermal cycling assessment for equipment that sees repeated load reversals in service.

Thermal and thermal-stress analysis

Steady-state and transient temperature fields, and the stresses and distortions they produce.

Bolted connection and seal analysis

Stud preload, flange rotation and metal-seal seating for ring-joint and subsea connections under combined pressure, temperature and external load.

Re-rating and re-qualification by analysis

Assessing an existing design at a higher pressure rating, a wider temperature range, or against a newer standard revision — with the calculation trail to support the change.

What you receive

Analysis report

A complete report stating geometry, material properties, boundary conditions, load cases and every assumption made — written so a reviewer can follow how the result was reached, not just what it was.

Mesh and convergence evidence

Element type, mesh density, refinement in the regions that matter, and the convergence study that shows the result is not mesh-dependent.

Stress plots and margin summary

Contour plots at each load case with a tabulated summary of calculated stress against allowable, so the margins are visible at a glance rather than buried in appendices.

Code and standard comparison

Results set against ASME BPVC Section VIII Division 2 Part 5, API 6X clause by clause, in a form your reviewer or certifying body can check directly.

Model files handed over

Analysis run in Ansys, Abaqus, Nastran, Creo Simulate, SolidWorks Simulation, with the solver model and geometry handed over on request in the native format or as neutral geometry. You are not locked in.

Design validation documentation

Where the analysis supports a qualification or re-rating, the documentation package to accompany it — formatted to your templates and document numbering.

How we work

Send us the geometry and the duty

A model, a drawing, or the pressure and temperature conditions. If you are not sure which analyses the case needs, that is part of what we will tell you.

You get an analysis plan

Which analyses the case actually requires and which it does not, the acceptance criteria we will work to, the deliverables and the timeline — before anything is committed.

Modelling starts inside a week

Our in-house engineers begin immediately, without a recruitment cycle or added permanent headcount on your side.

You review before we finalise

Interim review of model setup and assumptions before the full run, so a wrong boundary condition is caught early rather than found in the final report.

Need a design validated?

Send the geometry and the duty conditions. We will tell you which analyses the case actually needs — and which it does not.
