WHAT IS DIFFERENTDefence vs. Oil & Gas
REGULATORY ASPECTSMaintenance Management
Regulatory and Class• Focus in regulation:
• Internal control - documentation
• Work processes – Management Regulation (MR) § 10
• Risk reduction – MR, § 1
• Barrier mgmt – MR, § 2
• Maintenance - ”Activity regulation § 43-46”
• Criticality according to Norsok Z-008 or equivalent
• Methodology selection and documentation
• Criticality basis for PM, CM and spare parts
• Failure modes (FMEA/RCM) basis for maintenance activities
• Vessels normally under maritime rules/class
• PSA Regulations
MAINTENANCE STRATEGYMaintenance Management
Maintenance strategy (Pintelon et al., 2006)
Strategy provides a sense of direction, integrity and purpose. It guides in making a series of unified and integrated decisions to achieve objectives
Maintenance strategy can be defined as a series of unified and integrated pattern of decisions made in four structural and six infrastructural decision elements

Maintenance Management
Criticality assessment (NORSOK Z-008)
What is a criticality evaluation?
─ A way to group (classify) equipment dependent of consequence of failures
What are the purposes of the criticality evaluation?
─ to establish a maintenance program with the right priority on activities
─ to specify a common spare-part strategy for equipment of equal importance. (availability of spares)
─ to standardize maintenance programs
─ to decide the extent and quality of technical documentation
─ one of the elements deciding the priority on corrective maintenance activities
Work process “Streamlined RCM” based PM-program

Consequence S- Safety & environment P- Production availability C- Economic losses
3 - High
Potential for serious personnel injuries. May render safety systems inoperable. Potential for fire in classified areas.
Stop in production/ significant reduced rate of production exceeding X hours (specify duration) within a defined period of time.
Substantial cost
- exceeding Y NOK (specify cost limit)
2 – Medium
Potential for injuries requiring medical treatment. Limited effect on safety systems controlling hydrocarbons
No potential for fire in classified areas.
Brief stop in production/ reduced rate of production lasting less than X hours (specify duration) within a defined period of time.
Moderate cost between Z – Y NOK. (Specify cost limits)
1 – Low
No potential for: Injuries, fire or effect on safety systems.
No effect on production within a defined period of time.
Insignificant cost less than Z NOK. (Specify cost limit)

Maintenance concepts - example
Together with a predetermined service level for the critical spare parts Stock Optimiser can provide;
• Spare parts demand per period for both corrective and planned maintenance
• Analysis against existing stock• Sensitivity analyses• Cost information over time• Materials planning input

Total amount of sparepartsOne should use the 80 - 20 rule when analysing store.Exclude from analyses: (examples)
Standardparts, Partswith low price, parts with short lead time, parts to be ordered in bulk etc
Spare parts evaluation
• Spare part selection based on criticality classification
• Analysis include:• First year operating spares
• Review of vendor recommondated spares for operation past first year
• ”Insurance spares”
CMMS Integration
Deliverables
• Maintenance Strategy and work process according to MR §10 (optional)
• Tag hierarchy facilitating PM program
• Criticality according to AR §43
• PM Program according to AR §44
─ Including Barriers and SIL requirements
Maintenance Management
• Link existing procedures and company policies to a maintenance management loop
• Identify GAPs• Basis for communication with the PSA

Technical hierarchy
• Plant structure (data model)• Equipment identification• Link to documantation and drawings• Equipment must be identifiable offshore
─ AOC requrement
Criticality analysis
• Criticality for all main functions and sub-functions• According to AR §43 and NORSOK Z-008• All background decissions documented
PM program
• Maintenance Concepts─ equipment strategies
• Uploaded to CMMS• Class requirements
included in evaluation• AGR Library of basic
eqipment• RCM for client specific
equipment• Involvement of offshore
personnel─ AOC requirements
