Problem Definition:
The client experienced excessive vibration of piping in one of their critical and large facilities during startup and shutdown.

EAMEC Scope:

• Review the piping system and field observations.
• Investigate the root cause of vibration.
• Provide mitigations to reduce or eliminate vibration.
• Develop a Construction Work Package for the field construction company to execute the changes.
• Provide construction support during the modifications.

Proposed Solution:

• Conduct dynamic analysis on the piping system.
• Install anti-vibration clamps at key locations.
• Review and reinforce pipe support structures to withstand dynamic forces.

Steps Taken:

• Reviewed pressure surge profiles and calculated unbalanced forces.
• Built a stress model for the piping and performed a time history analysis.
• Reviewed vibration modes and matched with field observations.
• Proposed anti-vibration pipe clamps and structural reinforcements.

Deliverables:

• Dynamic analysis report.
• Construction work package for modifications.

Outcomes and Benefits for the Client:

• Significant reduction or elimination of vibration.
• Safer system operation and prolonged service life.
• Prevention of high costs due to vibration-induced failures.
