Finite element analysis (FEA) is a valuable technique for analyzing mechanical components and systems. The finite element method is a useful tool for predicting and evaluating component responses to loading and providing key information as to how it will perform in service.  We have experience developing Integrity Evaluation of Pressure Vessel in service, Develop Projects of new Pressure Vessel design, designing by rules according to the standards ASME Section VIII Division 1 and 2 taking in account the best practices of Exxon and Shell flexibility analysis to predict the mechanical performance and provide the solutions to help obtain the best performance and reliability of the equipment.
