EXXONMOBIL GLOBAL RELIABILITY SYSTEM
GRS
Agenda
• System Overview
• Q&A
Objectives
–Review ExxonMobil’s Global Reliability System in
sufficient detail to provide an understanding of how
the system achieves
•Improved facility reliability
•Improved maintenance effectiveness
2
GRS - BACKGROUND
GRS
GRS supersedes and replaces earlier ExxonMobil
systems which date from the mid 90’s
GRS is a Global Common System, a common framework for
Reliability Improvement
• Facilitates Identification and Accelerated Application of Global
Best Practices
The System has requirements, supported by practices; benefits are
obtained from the Practices, the “how to’s”

targets
Reliability is the probability that assets will
produce the required product, at the target rate
without interruption for a predetermined time,
within applicable quality specifications, when
the assets are operated within a specified design
and operating envelope.

In order to achieve this RELIABILITY,
DEFINE the CAPABILITY of the process and equipment
Operating Envelopes (6B)
Equipment Strategies (6C)
Ensure that we OPERATE WITHIN THAT CAPABILITY
Operator Care (6H)
Abnormal and Non-Routine Operation (6I)
To be COMPETITIVE,
OPTIMIZE support effort consistent with the potential loss
and probability of that loss

ELEMENT 1 - LEADERSHIP
Expected Results:
Sustainable reliability, availability and manufacturing
(maintenance and operations) cost performance that is consistent with
Business objectives
An organization that understands and is working to achieve the
site's reliability, availability, and manufacturing cost objectives
Leadership and commitment that is demonstrated through
management behavior and visible actions

Element 6F - Turnaround PS&E
Site long range plans developed to identify timing for SD/TA’s and
long term milestones
Provide Steering Committee and organizational structure to manage
TA
Establish the TA strategies, objectives, basis, and key constraints
Utilize a milestone plan based on SD/TA complexity covering all
major activities
Integrate Maintenance, Operations, Inspection & Projects plans &
schedules including pre and post work activities
Identification of critical and near-critical path work; includes risk
assessing potential discoverables and impact on SD/TA objectives
Schedule key reviews throughout Planning & Scheduling, Execution
and Closeout to steward progress, cost & performance

the business objectives
Site design and equipment selection incorporates Reliability Best
Practices. Reliability Reviews conducted by knowledgeable site
representatives and technical specialists
Facilities meet the requirements of the Global Reliability System prior
to commissioning and startup
