Finite Element Analysis

Performing finite element analysis (stress, thermal, vibration & fatigue) of equipment, ensuring equipment structural integrity, performance and reliability. This includes both the design/analysis of new equipment and the analysis of operating equipment – to Engineering Codes including AWS, API and ASME Boiler & Pressure Vessel (B&PV).

The benefits of finite element analysis (FEA) include:
>>> Determining a structure’s response to mechanical, vibratory and other loads, thus solving design challenges without arduous manual iterations or prototyping
>>> Optimizing designs for weight and fabrication/ cost savings

We have performed FEA on numerous components (some operating in extreme environments) including pressure vessels, bellows, heat exchangers, decanters and welded/ nonwelded assemblies to ensure they operate over the intended design life.

If such equipment is found to have limited life, we develop improved designs and/or repair procedures. We have assisted clients in industries including energy, manufacturing and petrochemical.
