Process Safety · Create the barriers
Design integrity
Purpose
Barriers against a major accident are identified, specified and built to be fit for purpose from the outset. Hazards are identified, risk is reduced as low as reasonably practicable, and each barrier is given a performance standard it must meet for the rest of its life. Change to plant or wells goes back through the same discipline.
The question this lens asks
“Does this document create a barrier against a major accident, keep one working, keep work inside one, or build the people who do?”
Belongs here
- Hazard identification and risk assessment (HAZID, HAZOP, formal safety assessment)
- Major accident hazard, risk acceptance and ALARP standards
- Performance standards for safety and environmental critical elements
- Engineering design standards and safety technical requirements
- Well design and planning: pore pressure, overburden, anti-collision, suspension
- Management of change for plant and wells; commissioning and handover into service
Does not belong here
- Inspection, testing and maintenance of barriers once in service (Asset integrity)
- Procedures for operating the plant (Operating integrity)
