In highly regulated industries such as oil and gas, petrochemicals, chemicals, power and pipelines, change itself is a major source of risk. That is why leading regulations require a structured, risk-based Management of Change (MOC) process, to prevent unintended consequences for people safety, asset integrity, environmental protection and operational continuity.
What is MOC?
MOC is a technical risk management process used to plan, assess, approve and control changes to:
- Process conditions.
- Equipment and materials.
- Technology.
- Procedures.
- Organisation.
Why MOC matters
- It prevents incidents.
- It strengthens compliance.
- It protects people, assets and the environment.
- It enables safer innovation.
When is MOC required?
- For safety-critical processes and equipment.
- For pipelines and high-consequence areas.
- For changes to procedures or roles.
Replacement in Kind (RIK)
A like-for-like replacement, with no change to the design basis or the risk, does not need MOC.
