Steps to Define Your
Safety Critical Equipment (SCE)
• Define your Barriers / Categories and
Owners
• Maintenance / Reporting Strategy
• Initial Identification of SCEs
• Review with Technical Authorities, Safety
Engineering, Independent Verifier
• Finalize your SCEs (30-50% of your asset
register)

Define your
Maintenance / Reporting
Strategy
What is my SCE Maintenance / Reporting
Strategy
Fire and Gas Detection – Loop Level
Pipeline Isolation – Valve or Item Level
UPS – Battery or Item Level
Pressure Vessels – Item Level
Emergency Lighting – Loop or Area Level
Initial Identification of SCEs
What are my SCEs?
Must Start with a Good Asset Structure
Fire and Gas Detection:
Detectors – Gas, Flame, Heat, Etc.
Defined / Maintained by Platform/Vessel,
Deck, Zone, Loop, Area, Item?
How are these defined?
EX Equipment, Structures (TS,SS),
Lifeboats, Emergency Lighting, ESD
Performance Standards
• Definition – Documentation of the specific
measureable targets of an SCE to assure
it is available and functioning to prevent or
mitigate a Major Accident
• Design Vs Measurable?
– The Escape Route will be 1 meter wide
– The Escape Route will be free of obstruction
Performance Standards should be:
Understandable and Measurable
• Technicians need to be able to pick up a PS and
understand exactly what they are required to do.
• The Assurance Activities should be measurable
with either a Y/N or with a calculative response.
– valve closes <30 seconds
– Gas Detector alarms at >10 PPM
– Emergency Lighting works? Y/N
Not Understandable and Not Measurable
