Subsea Reliability and Integrity Management
• Reliability and Integrity Management
– Have very similar intent - almost the same definition
– Treated separately by some - integrated in others
– Can appear as competing philosophies in organisations
• Typical Problems areas when not integrated

Duplication of effort
Conflicting goals and requirements
Conflicting management roles and responsibilities
Gaps and Blind spots
Proposed new RP
• Integrate two fundamentally important management systems
– Subsea reliability engineering
– integrity management
• Unify under single SRIMS process
• Supported by a single, fully aligned, API RP.
• Aim :
– To develop guidance on management practices and tools to assess,
optimise, manage and meet Safety, Environment and Production goals
– To bring Design and Operations stage into closer alignment- including
critical handover period
– Operations to have greater input and control over design decisions
Motive and Approach
• Motive
– Greater safety and environmental protection
– More cost effective production
– Integration of best practices in reliability engineering, technical risk
management and Operational integrity Management
• Address :
– Reliability and Integrity Management Leadership and Direction
– Coherence and consistency of process and assessment between
design and operation
– Data Management, feed back and organizational learning
– System Integrity

Scope (TBD)
• Reliability Engineering and Integrity Management Systems (building on API
RP 17N and other RP and standards)
– Including Operations input at design stage
– Handover to Operations
– Reliability Management of operating assets
• Practical reliability and integrity assessment tools and management tools
• Application to
– Subsea production systems
– subsea HIPPS
– Drilling and BOP systems
• Failure Data Collection and on-line/in-service condition monitoring of
subsea systems
• Etc.

Impact on SC17
•
Options for Consideration
1. Update API 17N (Subsea reliability/technical risk managementto address integration between reliability and integrity
2. New API 17 standard/RP on Reliability and Integrity
management with updates and cross references to 17N and 17O
and 17Q
3. API 17O (HIPPS) - Include annex on Reliability Modelling and
Calculation of System Safety for HIPPS
4. Any other suggestions?
