Mechanical Integrity

As manufacturing facilities age, maintaining the Mechanical
Integrity (MI) of equipment is critical to process safety.
CH2M HILL helps our clients address mechanical integrity
concerns withprogram development, program effectiveness
audits, equipment and relief calculations, and corrective action
planning.
Why Should I be Concerned About Mechanical
Integrity?
Mechanical Integrity programfaults represent 19% of the citations under the OSHA
National Emphasis Programs (NEP) for Refineries. Incident investigation often
find mechanical integrity issues to be a root cause or contributingfactor in most
catastrophic events.
Benefits
Mechanical systems designed to contain chemicals within the process, can become
less reliable over time. A well planned, structured, and optimizedmechanical
integrity program combats the effects of aging to provide continued service
confidence. Benefits include:
• Appropriately scheduled maintenance on wear components to minimized
unplannedfailure, efficiency loss, and leaks
• Informed decision making to repair or replace equipment or piping systems before
system integrity is compromised
• Confidence that safety instrumented systemswill perform as planned when needed
• Assurance that relief systems are sized appropriately for overpressure scenarios
• Procedures that address maintenance issues in a timely and reliable manner
•Well founded basis for specification revision to improve economic life of equipment
