Excellence in Reliability
•
•
Reliability : Availability of operating unit on demand
Focused on “Excellence” and not on “Compliance” applies to all equipment, NOT JUST PSM covered!
OPERATIONAL EXCELLENCE PROGRAM
Safety – Environment – Reliability – Cost – Quality
People – Community
•
Demonstrated experience in reliability; driving excellence
in safety, environmental, quality and cost performance
Competitive Advantage

Why Focus on Stationary Equipment?
•
•
Accounts for >50% of the capital /
maintenance cost and reliability events
Safety, Environment and Reliability
•
•
•
•
•
•
Accounts for a large % of total equipment
Very high consequence due to stored volume
Accounts for very high % of incidents
Critical components in thin sections by design
Extreme operating conditions and damage
mechanisms. In most cases damage is not
immediate
On-line feed back is not available
Stationary Equipment reliability leads overall reliability.

Stationary Equipment Reliability Focus Areas
Management Systems
• Performance / Inspection / Maintenance
Standards, Workflows, KPI and Audits
7
Management Support
Engineering Practices
• Continuous, consistent, and at
the highest and all levels
• Global Engineering Standards,
master databases
People
Reliability Practices
• Knowledge transfer, benchmarking,
unit inspector concept, training
• Corrosion Manual, RBI, Data
Management System, Focused
Reliability Improvement Programs such
as CUI
Implementation Discipline
Operations Discipline
• Maintenance, turnaround, projects,
purchasing, warehouse, QA/QC
• MI-critical variables, MOC,
operator rounds, incident reporting
Management Systems
Compliance Audits
Verification system is functioning by outside
representatives.
Key Performance Indicators
Performance-related actionable metrics for
reliability and cost improvement
Engineering, Inspection and
Maintenance Standards
Mandatory technical requirements – Single
owner responsibility and accountability
Inspection and Maintenance
Procedures
“How to” documents – plant procedures
containing workflow, forms, roles and
responsibilities and accountability
Performance Standards
Reliability Beliefs and
Principles
8
Management systems required at each site
Example: A management system exists for
notifying past due inspections and
recommendations
Foundation
Engineering Practices
•
•
•
Global Engineering Standards and Piping Specifications
Single sponsor – responsibility and accountability
Mandatory requirements – reduces debate
•
•
•
•
•
Requires strong management support for implementation
Plant or project addenda and deviation process
Administered and kept evergreen by a dedicated group
Continuous improvement - Process to incorporate lessons learned
and best practices
Robust computer-based systems for engineering data
management
Reliability by design

-
External inspections in lieu of
internal inspections (general
corrosion) resulting in turnaround
extensions and cost reduction
-
Focus on external damage
-
Cost savings through interval
optimization
-
Cost savings through storage tank
internal inspection interval
optimization
Pressure vessels, piping
inspection interval and
plans
Retube Analysis Tool
(RAT)
API RBI, draft Appendix
O with internal best
practices
Benefits
Storage tanks
Improved bundle reliability
Minimizing unplanned retubes
RBI Implementation
•
•
•
Over 30,000 equipment items evaluated
$6.5MM annual cost avoidance
Study results are being used to:
•
•
•
•
Determine inspection TA work scope
Focus resource spending to match damage source → 80%
leaks are external
Unit inspector, corrosion specialist and process engineer
participation is critical
•
•
12
Identify and budget for CUI
Accuracy of process, design and inspection input data
Review of results (especially if a contractor is involved)
Mock Exchanger

Focused Reliability Improvement Programs
•
Issues are global in nature and require greater focus in
terms of resources and commitment - Integral to Lyondell’s
long term reliability philosophy
•Corrosion-under-Insulation (CUI)
•Inspection catch-up
•Storage tank inspection (AST)
•Structural remediation
•Heat exchanger reliability
•Cooling water performance
improvement
•Painting program
•Furnace re-tube
•Auto-refrigeration and brittle
fracture analysis
•Underground leak prevention
•Technical Directives – Small bore
branch connections
• Success factors: champions, leadership and ownership
Special programs can make step improvement
15
CUI Program
•
•
•
•
Carbon steel in 25 – 300 degree F and stainless steel in ESCC
temperature range
Over $150MM committed in 12 years
Ceramic coating/metal cages for personnel protection
Insulation Elimination
•
•
New Coatings and Fire Proofing
•
•
•
Coatings for cold and damp surfaces
Subliming-type fireproofing
Rope Access
•
•
16
Areas not requiring personnel protection and not justified for energy
conservation
Tower CUI inspection and caulking
Evaluation of each application for cost effectiveness
CORROSION-UNDER-INSULATION FINDINGS
Plant Outages; Flaring;
Fires; Major Losses
XX
•Permanent repairs done on the run
•Temp. Repairs, Leak Boxes
•OK to run, but must repair at T/A
•Repairs completed during T/A
•Pin hole leaks, installed leak clamp
CUI active, metal loss acceptable,
blast, clean and paint

Operations Discipline
•
•
Management of change process – involvement of inspection
department
Operator rounds
•
•
•
•
•
Equipment and piping visual inspections
Example: Insulation damage and CUI awareness
Reporting all non-utility leaks. Consider leaks as failure of
RBI to predict - opportunity for improvement
MI critical variables and operating envelop. Incident
investigation when exceeded and action plan
Operator training
Operators are first-line inspectors
18
Maintenance / Turnarounds / Projects
•
•
•
•
•
•
•
Risk-based tools for turnaround scope development and
prioritization
Total cost of ownership philosophy
Approved Vendor List and audit program
Vendor/Contractor Alliances
Shop fabrication and field construction QA/QC
Receiving inspection, PMI, warehouse control
Quality performance indicators
This is where the “rubber meets the road”
19
KPIs and Audits
•
•
•
•
Performance related actionable metrics to improve reliability
and cost objectives
Internal metrics: Past due inspections & recommendations,
Number of leaks, Weld reject rates, PMI reject rate
External benchmarking - Solomon and API survey
Performance Audits
•
•
•
Verification of management systems
Verification of performance - vertical slice audit
High level plant management support
Know where you are and where you are going
