Legal framework (OHS)

A ‘General Duties’ regime
Performance-based, but with prescriptive elements
An independent Regulator (NOPSEMA)
A facility operators safety case is used as a

permissioning document, i.e. must be accepted in

rder to undertake activities.

Future directions

Design notification style scheme:

– Focus on concept selection & design – Required for production facilities – Basis for ongoing dialog, transitioning into submission of a safety case

SLIDE 16

Industry leadership challenge

Shaping and supporting an organisational

culture which embraces and values inherent safety to effectively manage risk, by:

– Early application; – Minimising hazards at their source; – Designing out hazards in preference to designing in control measure complexity; – Ensuring systems fail safe when things go wrong.
