A journey beyond level 3 API 579-1 / ASME FFS-1

 Predict and understand the mechanical behavior of parts and equipment for complex layouts, with multiple loads, parameters and variables that need to be tested in different magnitudes, and even more, explore their behavior and limits, challenged us to look for a tool more powerful than the Classic Calculation.

Modeling and analysis through FEA (Finite Element Analysis), along with the results of the inspections, design experience and root cause analysis, has enabled us test scenarios, determine operating limits, and establish the conditions that could cause a failure going beyond level 3 API 579-1 / ASME FFS-1.

Also through this type of analysis we have managed to reproduce events that damaged equipment. Thanks to those also to determine structural mechanics resistance in the final condition, scope of the parts to be upgraded or replaced, and with this define safe strategies for repairs.

 The implementation of this new process has prompted us to a cultural change deepening our levels of evaluation, through improvements in the design and operation, determining with greater precision the remaining life, and being more effective in the definition of the fitness for service of our assets.
