2. Content Introduction Why this study Output Team Planning System boundaries Functional Block diagram & Major Equipment Key information Let’s get started

3. Introduction From within the Maintenance Forum the initiative was born to conduct a “Virtual RCM” study to learn and share knowledge in an interactive way. A Case & Operating Context is defined for the Company Ollie’s Olefins based on business impact/criticality. There are a lot of methods which are called RCM In this study the RCM2 methodology of John Moubray will be applied

4. Goal and output Make a maintenance plan which preserve the functions of the chosen Cooling Fan System throughout the technologically useful live by selecting and applying the most cost effective technique for managing failures and their consequences Output: -Maintenance schema -Operator Care Instruction -Modifications (can also be operational procedure)

5. Team Facilitator: Rogier Team members: (list to be defined) It is nice to have a fixed team giving input during all steps to prevent having discussions all over again.

6. Planning The project kick-off is in week 41 after publishing project plan on forum Minimum 1 session a week depending on input A live chat or telecom can be organised to discuss different views if necessary Estimated time needed is 11 sessions, completion date end 2007 Participant are assumed to have basic RCM knowledge starting the study Session Content Kick off – Setup project and team1 session (WK 42) Functions and performance standards1 sessions Functional Failures & Failure Modes2 sessions Failure Effects2 sessions Failure Consequences 2 sessions The RCM Task Selection Process3 sessions Spare2 sessions Finalizing report by facilitator 1 week

8. Funct. Block diagram & Major Equipement

9. Key information Plant located on island near to sea Operation 24h/7 days a week /365 day’s a year It can sell all product it can make 30 equal systems in production unit System supplies ambient air to refrigeration system Performance indicator: If fan < 200 RPM audible alarm sounds in control room Revenue loss of $5000 per hour if one system down for > 30 min System cost a lot of maintenance hours due to breakdown disturbing the process (how much cost / failure history?)

10. Let’s get started -Who is willing to be part of the team? -let share email addresses within the team, mail me your email address please? -When the team is complete I will setup a platform to share / add remark or something to be able to give your input when it suits your agenda -We are in different time zone's I think, so live discussion can be a problem, Can we make an overview of possibilities when to discuss /chat live? -To share learning's everyone get’s read rights on chosen platform and only team member write rights All information needed for study will documented and posted -Final Result per session will be post on maintenanceforum to share learning -English is not everyone’s native language so can give misunderstanding, treat everyone with respect, lets focus on the big picture and not argue about minor language details.

11. Step 1 functions -Step 1 – Describing Functions We have enough information to start with defining the function A function statement should consist of a verb, an object and a desired standard of performance If we miss relevant information it will be an action point for someone to retrieve of we make a decision as a group We can use the template supplied by Rolly12 Other steps will be added during the study

12. Step 1 functions Primary functions: What's the main reason the asset exist? Secondary functions: Asset is expected to fulfill one ore more functions in addition to their primary function To help none of these functions is overlooked they are diveided in 7 categories (ESCAPES): - Environmental integrity - Safety/structural integrity - Control/containment/comfort - Appearance - Protection - Economy/Efficiency - Superfluous functions One of the most mistakes in the RCM process is carrying out the analysis on too low level in the equipment hierarchy.

13. Step 2 Functional Failures Step 2 – Describing Functional Failures A functional failure is defined as the inability of any asset to fulfil a function to a standard of performance which is acceptable to the user Functional Failures can be placed under the following headings: partial and total failure Upper and lower limits Gauges and indicators The operating context

14. Step 2 Functional Failures Who shoulls set the standard?
