Description
This technical presentation focuses on employing Finite Element Analysis (FEA) to investigate the dynamic behaviour of a rotating equipment under continuous vibration due to structural resonance. FEA analysis is employed to visualize and quantify the dynamic response of the compressor under operational conditions. Prior to FEA, and Modal Analysis (MA) was performed to identify the natural frequencies, mode shapes, and damping of the compressor system, providing insights into its structural dynamics.
By integrating these techniques, a comprehensive understanding of the compressor's vibration characteristics and potential areas of improvement can be acquired. This can be achieved once a correlation is established between FEA Modal and MA Modal, in which any design modification of Structural Dynamic Modification (SDM) can be done in virtual environment.
This presentation will deep dive on how each analysis was demonstrated on a multistage reciprocating compressor package driven by gas engine installed in an offshore facility resulting to improved reliability, integrity, and safety. Employing a structured workflow is key to obtain a feasible resolution on a systemic vibration issue involving resonance and structural integrity deficiencies. The outcome from implementation of remedial solution is also discussed where substantial improvement was seen from the vibration analysis.
