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 management- to 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?
