•
Identifies the hazards and risks;
•
Describes how the risks are controlled;
and
•
Describes the safety management system
in place to ensure the controls are
effectively and consistently applied
.
A safety case is a document produced by
the operator of a facility which:
What is a Safety Case?
Safety case is a process, not just a
document
•
It introduces a need for an audit trail with
documented decisions
•
Brings a greater awareness of hazards and
their management

Different elements of safety

address personal safety from
those that address process
safety
So it is not enough to say
that SMS addresses safety.
The Management of Safety
Recent observations suggest that industry focus is on slips, trips and falls …

… with reducing attention paid to maintenance of
technical integrity and major hazard controls.
“But the more profound problem is a failure to
put risks in perspective. BP and other
companies tend to measure safety and
environmental compliance on a day-to-day,
checklist basis, to the point of basing
executive bonuses on those metrics. But even
if worker accident rates fall to zero, that may
reveal nothing about the risk of a major
disaster.”
The Management of Safety
Widely accepted failings of prescription include:
Traditional means of the management of safety
has been prescriptive in nature.
The Management of Safety
• Quickly out of date as industry changes
• Industry only performs to minimum – no incentive to
Widely accepted failings of prescription include:
The Management of Safety
• Industry lets regulator work out what is needed and
comply verbatim – so operator fails to identify or understand the hazards and risks they are
supposed to manage – controls may be inadequate or inappropriate
• Prescriptive regulations become a hurdle to be
cleared, with the focus on the hurdle, not on managing the hazard
The witnesses’ reliance on merely a qualitative
opinion showed, in my view, a dangerously
superficial approach to a major hazard.

Why do we need a Safety Case?
• How do you demonstrate adequacy of safety
management to Company Board otherwise?
• ISO 9000 process & ISO 31000 elements link directly
to the Safety Case process
• So good quality management requires a Safety Case!!
• Demands of duty of care – how do you demonstrate
Why do we need a Safety Case?
• International companies – consistency of application
across assets ( e.g. Shell, BP, Union Carbide)
• How do you demonstrate safety in design without
Safety Case? – Are standards / Class enough?
• How else could hazards and the SMS be linked?
• HAZOP is an integrity assurance process – not hazard
identification!!
• So if just apply codes and standards, what other
hazards/ risk mitigation measures would be missed?
Safety Cases – lessons learned?
The Enemies of Safety are : Complacency
Arrogance Ignorance
Professor Nancy Leveson, MIT, “Future Trends in Process Safety”, Honeywell User Group Summit, June 2007
Factors in Complacency
• Discounting risk
• Over-relying on redundancy
• Unrealistic risk assessment
• Ignoring low-probability, high-consequence events
• Assuming risk decreases over time
• Ignoring warning signs
Reflecting on recent major accident events -does any of the above sound familiar ?
Professor Nancy Leveson, MIT, “Future Trends in Process Safety”, Honeywell User Group Summit, June 2007
• Schedule
• Cost
• Performance
• Safety
Professor Nancy Leveson, MIT, “Future Trends in Process Safety”, Honeywell User Group Summit, June 2007
Do we effectively put this into practice ?
Managing Tradeoffs
Good risk management requires
understanding the outcomes, implications,
impact and tradeoffs between:
Example: Schedule Pressure and Safety Priority
0 0.2 0.4 0.6 0.8 1 1.2 1.4 0 0.2 0.4 0.6 0.8 1 1.2 1.4 Safety Priority S c h e d u le P re s s u re Low High Low High Overly aggressiveschedule enforcement has little effect on completion time (<2%) & cost, but has a large negative impact on safety
Priority of safety activities has a large positive impact, including a positive cost
Cost

Detailed Design
• Blowdown philosophy set early, with late application of safety case – identified problem resulting in
expensive change
Safety Cases – lessons learned?
• People / competence / skills gaps – a major ongoing
issue - with an ageing workforce how do we
effectively manage current and future projects and operations?
• Managing the wrong thing – i.e. managing the detail
and overlooking the big picture (example is OHS vs MAE risk)
• The Myth of major shutdown / In-Water Surveys with no time off riser – how many projects achieve it?
Safety Cases – lessons learned?
• But we build this into the design basis and hence into
Oil Company and FPSO Contractor Relationships
Safety Cases – lessons learned?
• Typical contract arrangement gives minimal
incentives for overall safe performance, but generally penalties for being unsafe!
• The FPSO Contractor is contractually incentivized to
keep producing - they generally lose money if production stops – is there another way?
• The Safety Case can and should give the FPSO
Safety Cases – lessons learned?
• Lump sum / low cost Safety Case v quality and
understanding
• The outcomes of the Safety Case are not known till
well after the contract is signed – is lump sum a fair and realistic contract strategy?
Quote from Conlin et al:
Often the Safety Case is produced by following a prescriptive set of instructions which stifle true thought about whether defined activities are as safe as they need to be because it is easier to write a Safety Case that way and then to audit the Safety Case against the internal procedure.
Safety Cases – lessons learned?
And further from Conlin et al:
Because of the practice of describing the organisation that is in place rather than debating what options have been considered, the fact that safety science
(engineering?) has had insufficient input into the design is not being revealed.
Safety Cases – lessons learned?
Safety Cases are not off-the-shelf, production line exercises in documentation.
Safety Cases – lessons learned?
Some problems with Safety Case implementation
Just producing a book, ticking a box, does not meet the intent!
To be effective, the safety case process must be allowed to take its course, to examine critically and interact with the design and the organisation.
Safety Cases – lessons learned?
If you want a Ferrari, but only specify something with wheels and an engine, don’t complain when a second hand Toyota needing maintenance work appears on the driveway!
A suggested Blue Print for Success
• Management leadership – must have this to work • Apply realistic schedule and budget
• Develop and apply safety design philosophy • Do it early!
• Embed experienced Safety Engineer in engineering design team as interface to Formal Safety
Assessment team
• Apply risk based decision-making process • Create an audit trail
A suggested Blue Print for Success
• Safety Engineering will provide linkage across the interfaces • Marine • Production • Mooring • Subsea • Sub-surface
A suggested Blue Print for Success
• Operating envelope / management of risk – i.e. the
Safety Case should define the operating envelope and hence allows you to understand the area in which your operational risk controls need to be applied and are designed to work.
• How do you know you are operating outside the
envelope if you have not defined it or passed the knowledge on to operations!
• Manage carry forward of residual risk – the Safety Case provides a means of doing this in a way that allows the residual risk to be actively managed rather than forgotten.
• Basis for SMS – i.e. the Safety Case will provide a
means of linking the facility, the hazards identified, the operations and the hazard and risk controls, whether via hardware or the SMS
• Clarify and manage separation of OHS risk
(personal safety) and MAE risk (process safety) – the two triangles rather than one.
Benefits of Doing a Safety Case?
• Identifies low probability / high consequence events
and assists to understand and manage them
• Provides an Audit Trail for: quality, safety,
development and risk management deliverables
• Do it early enough and you should get optimum
design (from safety, risk & cost viewpoint)
• Without Safety Case, would you ever have a blast
Benefits of Doing a Safety Case?
• Enable targeted maintenance – i.e. to safety
critical elements through performance standards
• Culture change – always occurs with safety case
process, always positive
• So the Safety Case should allow you to efficiently
1. The Safety Case is not a silver bullet cure for all ills. It does offer, however, the best means available for
effective management of major hazard risks and process safety.
Conclusions
2. Effective development and implementation of the
Safety Case process requires significant effort by any organisation. This effort is well worthwhile as it can deliver:
– Cost benefits in project performance
– Increased performance in operations, due to greater reliability in plant, equipment and resources
– Improved communication of hazard management for the lifetime of the facility (i.e. a corporate memory!)
3. Safety Case provides a competent and auditable process for senior management to demonstrate management of development, project and
operational risk to satisfy corporate requirements
Conclusions
4. There is a trend that our industry may be focussing on occupational HSE with diminished attention to management of residual and process risk. Safety Case provides management focus to overcome this.
5. Quality and quantity of risk assessment combined with industry shortages of skilled personnel is a concerning issue going forward
Conclusions
6. With ongoing cost, schedule and implementation
pressures there are better ways to contract and manage the preparation of Safety Cases.
