Design Issues • Alarm management
– Address during design / commissioning.
• Material selection – Souring of the reservoir is a common outcome of
facilities that conduct produced water reinjection. – This generally results in a higher than anticipated H2S
content in well, process & rundown streams.
• Process vs Tanker – Interfaces between topsides and existing marine tanker
systems

Design Issues • Hazardous Area Electrical Equipment
– Non compliant & Poor installation
• Vibration and fatigue failures. – account for high proportion of Loss of Containment.
• Design for Africa vs Australian manning levels • Trend to retaining pump rooms
– lower cost of conversion vs higher risk.

Design Issues
• Critical Function Testing (CFT) – SCEs not meeting performance standards. – SCE often requires a production shutdown to CFT with
frequency implications. – Systems should allow for performance tracking /
reporting of SCE during unscheduled shutdowns.

Commissioning Issues • Safety-critical elements: performance non-
compliance: BDVs / SDVs • Incomplete commissioning
– construction debris – excessive punch list items – lack of Quality Assurance/Quality Control

Operational Issues • Inadequacies in competency / training
– Restart of plant and processes – cyclone disconnection complex tasks requiring technical skills and experience.
• Operators must ensure sufficient time for required competencies to be acquired

Operational Issues • Procedures Incorrect / Not Followed
– Procedures take time to achieve and should be considered as dynamic.
– Procedures should be validated or reviewed to reflect the current, best practice.
– Use Management of Change (MOC), otherwise procedures can be undermined, resulting in shortcuts and risk taking.

Operational Issues • Failure to complete Corrective Actions
– "Case to Operate", "Deviations”, "Temporary Operating Procedures”, and the like are used to justify continued operations
– Such permissions to operate should be time-limited and tracked to ensure permanent rectification is applied and maintained

Maintenance management • Variation between documented maintenance
system and how maintenance is actually conducted • Formal deferrals process not used – risks not
assessed • Auditing – inadequate

Emergency Management • Drills being undertaken with limited number of
scenarios • PA systems ineffective, emergency escape routes
not clearly marked or obstructed • Response times – not subject to performance
standards and not tested • Inadequate debriefs • Auditing - inadequate

• Positive feedback regarding process
• Useful introduction for new operators
• A limited opportunity to question:
– Safety & design philosophies
– Concept selection
– Design choices
– ALARP demonstration

Early Engagement Today: Challenges
• No provisions for Concept Selection & Design
• Dialog constraints (requests for further information)
• Decision making focus of the regulations
• Optional process, no submission trigger
= Sub-optimal arrangements with limited potential to improve safety outcomes.
