The document summarizes a presentation on Reliability Centered Maintenance (RCM) given at an IADC conference. It provides background on RCM, describing it as a process initiated in 1978 to improve aircraft maintenance. The presentation discusses the objectives of RCM as preserving system performance over time through cost-effective maintenance. It notes RCM is part of larger programs and aims to improve reliability by identifying and controlling failure modes. An example project applying RCM to marine riser tensioners is presented, resulting in a maintenance plan focusing on condition monitoring and on-site repair.

Quality without results is pointless.
Results without quality is boring.

Agenda
• Introduction and a bit of history;
• What do we want to achieve with RCM;
• RCM as part of a program not as end-solution;
• Payzone and pitfalls, do’s and don’ts;
• Project case.
Introduction and a bit of history
• The abbreviation RCM stands for Reliability Centered Maintenance.
• This has become an acronym, almost like a brand name.
• Initiated in 1978 by Mr. Nowlan and Mr. Heap to change the way aircraft
maintenance was done. (following up on MSG-2)

Introduction and a bit of history
• Followed up in several ways:
o MIL-STD-3404 ( + MIL-STD-1629)
o RCM-II / John Moubray
o RCM-Uptime / John D. Campbell
o SAE JA-1011 (RCM process evaluation)
• The abbreviation RCM stands for Reliability Centered Maintenance.
• This has become an acronym, almost like a brand name.
• Initiated in 1978 by Mr. Nowlan and Mr. Heap to change the way aircraft
maintenance was done. (following up on MSG-2)
Introduction and a bit of history
• Different approaches, many views and opinions.
• The Nowlan and Heap ‘variance’ is often referred
to as ‘the classical’ RCM.
• The Moubray ‘variance’ has a more in-depth approach
and the process (owned by the Aladon network).

• The Campbell ‘variance’ is a very practical approach and
has some extensions , perhaps more practical appealing.
• The SAE standard is a process evaluation to allow identification if
something might be called RCM.
• No matter which process is followed, some are successful where others fail
to achieve.
• All follow an almost identical path and similar ‘steps’.

Introduction and a bit of history
Presented is a high level summary of important RCM process information
and documentation.
Not focus on the process of RCM itself, that can be read and taught with
books and training.
Highlighted is what is not (almost) in the
books and documents but what is
required to make a RCM process successful.

What we do want to achieve
Critical principles.
 Logical, demonstrable, clear line of sight, focussed and descriptive
(tailored);
 Identification and prioritization of failure modes that affect system
performance;
 Select applicable and effective strategy to control the failure modes.
Objectives:
 Preservation of system functional performance (i.e. safety, operational,
compliance) over time of usage. (note; it’s preservation not reinstatement)
 Cost and Reliability optimization with effective and efficient maintenance
tasks without loss of safety or operational performance.
Many other objectives can be found by browsing i.e. the internet.
The objectives above are core objectives of RCM applications.

What we do want to achieve
RCM recommendations revolve (centred) around Reliability.
• Reliability is depicted by probability of failure of components or the system in
which the components perform.
• Performance also include safety or compliance performance not only
operational.
• Measuring RCM effectiveness involves being able to measure reliability /
performance.
• The consequence (effect) of component failure depends
on the criticality of the system of operation
of that component.
• Assessing risk is not a game but depicts the focus of your RCM process.
• A reliable system assures safe and efficient operations:
lower overall risk exposure.

What we do want to achieve
RCM recommendations revolve (centred) around Reliability.
•Component failure is affected by degradation or damage mechanisms (ref. to
failure modes)
•Effective maintenance focusses on mitigating these
mechanisms’ effects.
•In some cases failures require a design change
(think of recall actions), often beyond control.
•Some failures are related to overload, or unawareness
of people or less effective management systems,
beyond RCM control.
•RCM is not a holy grail for all problems but an effective
means to gain more control over reliability and added value of that.
•Operational success (Safety increase / NPT decrease ) is strongly dependent on
the reliability of technical equipment.
Payzone or pitfall: do’s and don’ts
Experience and research show why some programs are a success (and
others fail). Do’s and don'ts (not conclusive) :
I. Make a plan. Don’t skip organizing the process, implementation and how to
measure success.
II. Select appropriate KPI’s: can you measure (reliability) improvement?
III. RCM is a process not a project, it should be a continues loop of improvement.
IV. Review and refine the plan during the RCM process, allocate dedicated process
resources and assure sufficient available manpower during the whole process.
V. Assure a long and good management relationship and
engagement. Involve them as the other ones
in your RCM team: inform and report.
VI. Careful selection of initial assets:
tailoring to what matters most (safety, cost, NPT etc.)
VII. Consider evaluating your process with an
evaluation program (i.e. SAE standard) JA 1011

Payzone or pitfall: do’s and don’ts
Experience and research show why some programs are a success (and
others fail). Do’s and don’ts (not conclusive) :
VIII. RCM implementation is often last-on-the-line: all work can be ruined due to that.
IX. Have some quick-wins built in the process: early results motivate.
X. Assure ‘performance’ includes safety and not only operational performance.
XI. Include training in your set up, unawareness and misunderstanding lead to
confusion and lost focus (and money, interest and engagement).
XII. Assure that the assets can be maintained according what RCM recommends.
XIII. The achievements must be measurable and demonstrable:
it is important to pick assets of which it can be shown what the RCM process
achieves.
Project case
A Maintenance Optimization study for Marine Riser tensioners / MRT
(fall 2014)
Review of > 10 years of maintenance history for 74 rigs, > 15 different
OEM’s and > 45 different models of MRT systems.
Objective: identification of RCM strategies that eliminating the need for costly shop
overhauls by providing improved, predictive analytics, and allowing more repairs to
be made on the rig.
• MRT: Critical / costly maintenance – overhaul
• LORA ‘To be done on the rig’,
• Maintenance Strategy: searching for
Condition Based maintenance
• Finding predominant failure modes
• Best practice strategy appeared to be type
specific (based on recorded failure data)

• Result: an RCM based maintenance plan for the critical riser components failure
modes with specific attention for condition monitoring and on-site repair.
• Implementation pending as this involves a major change in maintenance culture
and maintenance system / management on a global scale (planning, scheduling…)

Application of an RCM process is beneficial with major added value.
• Reliability of systems and cost effective become more and more
important in the Oil and Gas Industry.
• Be prepared to embrace the do’s and don’ts and accept limitations.
