REPETITIVE FAILURES IN CRITICAL & MAIN PARTS - CENTRIFUGAL COMPRESSORS

Failure analysis: When a failure or unexpected shutdown occurs in a centrifugal compressor, a thorough failure analysis should be conducted to determine the root cause of the issue. This analysis should include a review of operating conditions, maintenance history, and equipment design.
Inspection and maintenance: Regular inspections and maintenance of critical parts in centrifugal compressors, such as impellers, bearings, seals, and casings, can help prevent unexpected failures. Maintenance activities should include monitoring of vibration and temperature, oil analysis, and visual inspections.
Operating procedures: Proper operating procedures for centrifugal compressors should be established and followed to minimize the risk of failures or unexpected shutdowns. These procedures should include guidelines for startup and shutdown, as well as operating parameters such as flow rate, pressure, and temperature.
Training: Operators and maintenance personnel should receive training on the proper operation and maintenance of centrifugal compressors. This training should cover topics such as equipment design, operating procedures, maintenance practices, and troubleshooting.
Design improvements: Centrifugal compressor manufacturers should continuously improve the design of their equipment to minimize the risk of failures or unexpected shutdowns. This can include the use of advanced materials, improved bearing designs, and better seals.
Root cause analysis: In addition to failure analysis, a root cause analysis should be conducted to identify the underlying cause of the failure or unexpected shutdown. This analysis should consider factors such as equipment design, operating conditions, and maintenance practices.
Industry standards: Industry standards such as API Standard 617 and 672 provide guidelines for the design, operation, and maintenance of centrifugal compressors. Compliance with these standards can help minimize the risk of failures or unexpected shutdowns.
Risk management: A comprehensive risk management program should be established to identify, evaluate, and mitigate risks associated with centrifugal compressors. This program should include risk assessments, risk mitigation plans, and contingency plans for unexpected failures or shutdowns.
