Understanding and managing risk - issues for design Presentation to Drill safe June 2014

by Stephen Matheson, Chief Inspector, Petroleum and Gas

So where are we now? What keeps us safe?

We (should) have: Safety management systems Risk assessment HazID/HAzOp Controls Design to standards Procedures Training

Things can go wrong

How can we be safe? Safe from what?

So design and initial Hazid is vital

How can we stop or control a hazard if we have not identified it?

Where automated machinery systems may exist

Pipe handlers / racking system

Elevators Top drives Tube assemblies Iron roughnecks

End user must consider designs

Have manufacturers? Undertaken formal safety assessment Identified all the risks First order elimination by: good engineering design standards

Considered Safety Integrity level (SIL) Performance level (PL) assessments for

operation

Requirements Manufacturer S696 comply with safety requirements Aware of hazard inform operator

Installer Comply with safety requirements

Operator Risk assessment/HazOp Must take action to ensure risk is ALARP Must revise SMP if aware of changes/event Must ensure compliance

Requirements WH&S Plant Code of Practice AS4024.1604 Safety of machinery: Design of

controls, general Principles for design etc

Learnings from incidents

What do you do when you see a safety alert? What do you do when there is a near

miss? Investigations – a time to cover up and ignore or a chance to learn and correct

Some learnings/ recommended actions

Review and ensure safe design, manufacture, and installation of operating plant Review of automated and semi-

automated plant Adequate safety assessment such as

Hazard and Operability assessment, Failure Mode Effect Analysis Certification of safety prior to starting

operation

Recommended actions

Review Management of Change Retraining Review manuals Review procedures

Put in place specific risk management training for safety critical positions

Create a simpler and more effective SMP Learn from incidents Safety first culture

Conclusion Industry are responsible for safety –

every person must play a part From an organisational perspective

there must be a focus on a process safety Ensuring high level controls in place for

high risk events and low probability high consequence events We don’t want compliance for

compliance sake – we want people to go home safely every day

Failure to manage interactions – consequence
