Every unplanned cylinder failure costs mining operations thousands of dollars in lost production. Hydraulic cylinder reliability mining operations seek directly impacts equipment availability, maintenance costs, and personnel safety. Yet reliability remains one of the most under-managed aspects of mining hydraulic systems.

Problem: Mining cylinder reliability suffers from predictable failure modes that are rarely systematically addressed. Most mines accept frequent cylinder replacement as normal operating cost rather than implementing systematic improvements that would dramatically reduce failure rates. What practical strategies actually improve mining cylinder reliability?

Answer: Improving reliability requires a systematic approach across four dimensions: proper initial specification, proactive maintenance, condition monitoring, and continuous improvement based on failure analysis. Hydraulic cylinder reliability mining operations can achieve requires addressing root causes, not just treating symptoms. This guide examines specific, actionable strategies that mines can implement immediately to reduce cylinder failure rates, extend service life, and lower total operating costs.

Mining equipment availability directly determines production output. For most surface mining operations, hydraulic cylinder failures account for 15-25% of all unplanned downtime. In underground operations, the percentage is often higher due to confined spaces and limited maintenance access.

Yet despite this significant impact, most mining operations lack systematic approaches to hydraulic cylinder reliability mining improvement. Cylinders are typically treated as consumable items — replaced when they fail, with little analysis of why they failed or what could prevent similar failures in the future.

This guide provides a comprehensive framework for improving mining hydraulic cylinder reliability. It covers specification strategies, maintenance practices, condition monitoring technologies, failure analysis methodologies, and continuous improvement processes that have demonstrated proven results in mining operations worldwide.

Understanding Mining Cylinder Failure Modes

Before implementing reliability improvements, you must understand how and why cylinders fail in mining service.

Primary Failure Modes

Seal Failure from Contamination: This accounts for approximately 50-60% of all mining cylinder failures. Abrasive mining dust penetrates wiper systems and scores rod surfaces. The damaged rod surface then rapidly wears seal lips, leading to external leakage and contamination ingress into the hydraulic system. This failure mode is progressive — problems start months before visible leakage occurs.

Rod Coating Degradation: Another 15-20% of failures result from rod coating breakdown. Standard hard chrome plating develops micro-cracks and porosity under mining conditions. Chloride and water penetrate these defects and attack the base material. The resulting corrosion creates surface irregularities that accelerate seal wear and eventually cause leakage.

Structural Fatigue: Approximately 10-15% of failures involve structural fatigue cracking. These failures typically occur at stress concentration points — weld toes, thread roots, sharp geometric transitions — and result from repeated loading cycles over time. Fatigue failures are often catastrophic and can cause significant safety hazards.

Shock Load Damage: 5-10% of failures result from acute shock load events. Excavators striking unexpected rock formations, haul trucks receiving dropped loads, and roof supports experiencing roof falls all create shock loads that can bend rods, break pistons, or damage end caps. These failures are often immediate and catastrophic.

Internal Wear and Bypass: The remaining 5-10% of failures involve internal wear that causes piston bypass and cylinder drift. Contamination in the hydraulic fluid wears piston seals and tube surfaces, gradually increasing internal leakage. This failure mode is progressive and often goes undetected until performance degradation becomes obvious.

Failure Progression Characteristics

Most hydraulic cylinder reliability mining failures follow predictable progression patterns. Understanding these patterns allows proactive intervention before catastrophic failure.

Early Warning Phase: During this phase, the failure mechanism is active but not yet producing visible symptoms. Rod coating may be developing micro-cracks. Seals may be experiencing accelerated but undetectable wear. Fatigue cracks may be initiating at the microscopic level. Detecting failures during this phase provides the maximum maintenance value.

Symptomatic Phase: During this phase, the failure produces measurable symptoms. Minor rod scoring becomes visible. Seal leakage begins as dampness rather than active dripping. Cylinder drift under load increases slightly. Pressure fluctuations may be detectable. Most condition monitoring technologies are designed to detect failures during this phase.

Catastrophic Phase: In this final phase, the failure becomes immediately obvious. Seals leak significant fluid. Rods bend or break. Cylinders lose functionality completely. Failure at this stage requires immediate maintenance, typically with significant production disruption. This is the most expensive point in the failure progression to perform maintenance.

Specification Strategy for Improved Reliability

The most impactful reliability decisions occur during initial cylinder specification. Hydraulic cylinder reliability mining operations achieve starts with proper engineering.

Safety Factor Specification

Minimum 4:1 Burst Safety Factor: Specify minimum 4:1 burst safety factor for all mining cylinders, increasing to 5:1 for critical applications. This additional margin provides capacity for shock loads that routinely exceed nominal working pressure. Many standard cylinders use 3:1 safety factors that provide insufficient margin for mining conditions.

Explicit Shock Load Calculation: Require suppliers to perform explicit shock load calculations as part of their design validation. Finite element analysis should simulate impact conditions up to twice the working pressure, not just nominal operating pressure. Shock load resistance should be a documented design requirement, not an accidental byproduct of general safety factors.

Fatigue Life Validation: Require fatigue life calculation using actual mining load spectra, not generic industrial assumptions. The design should demonstrate infinite fatigue life at operating loads and predictable, calculable life at overload conditions. Cyclic pressure testing to 100,000+ cycles should validate these calculations.

Sealing System Specification

Multi-Stage Wiper Requirement: Specify minimum dual-stage wiper systems, with triple-stage preferred for especially dusty applications. The system should include a metallic scraper removing large particles and heavy contamination, primary polyurethane wiper removing finer dust particles, and tertiary labyrinth or additional seal for extreme dust conditions. Never accept single-stage wiper systems for mining applications.

Seal Material Specification: Match seal materials to expected operating conditions. Standard polyurethane works for moderate temperature ranges. HNBR provides better low-temperature performance for arctic mining conditions. FKM materials handle high-temperature deep mining applications. Require material compatibility documentation for the specific hydraulic fluid in use.

Gland Drainage Design: Specify gland designs with positive drainage channels that prevent water and contamination accumulation. Some advanced designs also include positive air purge systems that create slight positive pressure inside the gland area, preventing contamination ingress during pressure cycling. Proper drainage can extend wiper life by 30-50%.

Rod Coating Specification

Move Beyond Hard Chrome: Standard hard chrome plating no longer represents best practice for mining cylinder reliability. HVOF tungsten carbide coatings deliver 2-3x service life improvement. Laser cladding delivers 3-5x improvement. The incremental cost of these coatings is almost always justified by reduced downtime and maintenance.

Coating Quality Requirements: Specify explicit coating quality requirements including thickness uniformity across the entire rod surface with no thin spots at edges or transitions, minimum bond strength verified by destructive testing of sample coupons, surface finish requirements of 4-8 micro-inch Ra after coating, and salt spray resistance verification per ASTM B117. Require suppliers to provide coating quality documentation with each cylinder.

Corrosion Allowance: Specify adequate base material corrosion allowance, particularly for underground mining applications where water chemistry may be aggressive. 0.050-0.125″ corrosion allowance provides material reserve as corrosion progresses.

Maintenance Strategy Optimization

Proper maintenance is the second major pillar of hydraulic cylinder reliability mining improvement.

Preventive Maintenance Program Design

Condition-Based Inspection Schedule: Implement condition-based inspection rather than fixed-interval replacement. Cylinders should be inspected at every scheduled machine service interval across four key areas. Rod surface condition is checked for scoring, pitting, or coating damage that indicates developing wear. Seal condition is assessed for dampness or active leakage signaling seal deterioration. Mounting points are examined for cracks or wear that could compromise structural integrity. Finally, functional testing measures piston drift under load to detect internal bypass before it affects performance.

Wiper Replacement Before Failure: Schedule wiper replacement based on condition assessment rather than waiting for failure. Most mining wipers should be replaced at 8,000-12,000 operating hours, depending on conditions. Replacing wipers before they wear out prevents contamination ingress that would otherwise damage both the cylinder and the entire hydraulic system.

Planned Overhaul Cycles: Implement planned cylinder overhaul cycles based on application and operating conditions.

These intervals should be adjusted based on actual condition monitoring data and operating environment severity. Underground applications typically require shorter intervals due to higher dust and moisture exposure.

Fluid Maintenance Practices

Target Cleanliness Levels: Maintain hydraulic fluid cleanliness to ISO 14/11 or better. This requires high-efficiency filtration on both the pressure and return sides of the hydraulic system, plus regular kidney-loop filtration during equipment idle periods. Fluid cleanliness directly impacts cylinder life — every contamination particle that enters the system accelerates wear throughout.

Regular Oil Analysis: Implement monthly oil analysis programs that track particle count, water content, viscosity, acid number, and wear metal concentrations. Trends in these parameters provide early warning of developing seal problems. Increasing iron or copper concentrations may indicate cylinder wear months before visible symptoms appear.

Filter Maintenance: Follow strict filter maintenance schedules. Return filters should be changed based on pressure drop indication rather than fixed time intervals. Pressure filters should be changed at manufacturer-recommended intervals, with additional sampling to verify performance. Breather filters are frequently overlooked but critically important for preventing airborne contamination ingress.

Condition Monitoring Technologies

Advanced condition monitoring allows early hydraulic cylinder reliability mining problem detection before catastrophic failure.

Vibration Analysis

Application: Vibration sensors mounted on cylinder end caps can detect developing mechanical problems including loose piston nuts, bearing wear, and developing structural cracking. Vibration signature analysis identifies specific failure modes before they produce functional degradation.

Implementation: Install permanently mounted accelerometers on critical cylinders. Collect baseline signatures during commissioning, then perform trend analysis at regular intervals. Alarm thresholds should be set based on deviation from baseline rather than generic industry standards.

Effectiveness: Vibration analysis is particularly effective for detecting fatigue cracking and mechanical looseness. It provides early warning — typically 2-6 months before catastrophic failure. This provides ample time to plan maintenance during scheduled shutdown periods.

Pressure Monitoring

Application: Continuous pressure monitoring detects abnormal pressure spikes that indicate developing shock load problems or valve malfunctions. Trend analysis identifies gradual performance degradation from increasing internal leakage. Pressure monitoring can also verify that accumulator systems are functioning properly to absorb shock loads.

Implementation: Install pressure transducers on both piston and rod sides of critical cylinders. Collect data continuously or at frequent intervals. Advanced systems can perform real-time analysis of pressure spike magnitude and frequency, providing early warning of developing problems.

Effectiveness: Pressure monitoring is highly effective for detecting internal leakage and shock load issues. It provides quantitative data that can be trended over time and correlated to actual cylinder condition. Integration with equipment control systems allows automated alarming when thresholds are exceeded.

Visual Inspection Technologies

Automated Rod Inspection: Machine vision systems can automatically inspect rod surfaces for scoring, coating damage, and corrosion during normal equipment operation. These systems typically install near the cylinder gland and capture high-resolution images during every cylinder cycle. Image analysis algorithms detect developing problems before they become visible to human inspectors.

Thermal Imaging: Infrared thermal imaging can detect abnormal seal friction that indicates impending failure. Failing seals generate additional heat from increased friction. Thermal cameras detect this temperature increase and provide early warning. This technology is particularly useful for inaccessible cylinders in underground applications.

Borescopic Inspection: For critical applications, periodic borescopic inspection of internal cylinder surfaces provides direct visual assessment of internal condition. This allows detection of tube scoring, piston seal degradation, and internal corrosion that would otherwise go undetected until functional failure occurs.

Performance Monitoring

Drift Testing: Periodic piston drift testing measures internal leakage under controlled load conditions. Increasing drift over time indicates progressive seal wear. This test is simple to perform and provides quantitative data on cylinder condition. Baseline drift values should be established for new cylinders, with maintenance triggered when drift exceeds a defined threshold.

Cycle Time Analysis: Monitoring cylinder cycle time over equipment operation provides indirect indication of internal condition. Gradually increasing cycle time may indicate increasing internal leakage or developing valve problems. This data is often available from existing equipment control systems with no additional sensor requirements.

Load Capacity Testing: Periodic load testing verifies that cylinders maintain full load capacity. Reduced load capacity indicates internal leakage or valve problems. This testing can often be integrated into normal production operations with appropriate instrumentation.

Failure Analysis and Continuous Improvement

Systematic failure analysis drives continuous hydraulic cylinder reliability mining improvement.

Root Cause Failure Analysis

Standardized Process: Implement a standardized failure analysis process for every cylinder failure. Technicians begin by collecting the failed cylinder before any cleaning or disassembly occurs to preserve critical evidence. They photograph all components in as-received condition, documenting contamination patterns, wear locations, and any visible damage. Next, they document all visible damage characteristics including location, severity, and failure morphology. Metallographic examination follows, performed by qualified personnel who look for fatigue cracking, corrosion patterns, or material defects. Finally, analysts examine failed seal components microscopically to determine wear patterns, chemical attack signs, thermal degradation evidence, or installation damage.

Classification System: Develop a failure classification system that categorizes failures by root cause, not just symptom. Categories should include contamination-induced seal failure, coating degradation, fatigue cracking, shock load damage, manufacturing defect, maintenance error, and fluid incompatibility. This classification allows trend analysis across the entire cylinder fleet.

Corrective Action Tracking: For each root cause identified, track specific corrective actions and verify their effectiveness. Simply replacing the cylinder without addressing the root cause guarantees repeat failures. Corrective actions may involve specification changes, maintenance procedure updates, or operator training.

Fleet Reliability Database

Centralized Tracking: Maintain a centralized database tracking every cylinder in the fleet, including cylinder identification and equipment location, installation date and operating hours at installation, all maintenance and repair events with date and operating hours, failure mode classification when failures occur, and condition monitoring data and trends.

Statistical Analysis: Perform regular statistical analysis on the database to identify failure mode trends across equipment types and operating areas. Identify cylinders with significantly higher or lower failure rates than average. Analyze the impact of specification changes, coating upgrades, and maintenance procedure improvements.

Life Prediction Modeling: Use historical data to develop statistical life prediction models for each cylinder type and application. These models predict expected remaining life based on current operating hours and condition monitoring data. Life prediction enables optimized maintenance scheduling and spare parts inventory management.

Economic Analysis of Reliability Improvement

Investing in hydraulic cylinder reliability mining improvement delivers substantial economic returns.

Cost of Failure Analysis

Direct Failure Costs: These include replacement cylinder cost, maintenance labor cost, rental equipment if required, and parts shipping and expediting charges. For a typical large mining cylinder, these direct costs range from $25,000 to $75,000 per failure.

Indirect Failure Costs: These are typically much larger and include lost production revenue, which is usually the largest cost component ranging from $50,000 to $500,000+ per day depending on equipment size, overtime and premium pay for emergency maintenance work, ancillary damage to other hydraulic components from contamination, safety incident risk and potential liability, and environmental cleanup costs for hydraulic fluid spills.

Total Cost Impact: Total failure cost typically ranges from 5x to 20x the direct cylinder replacement cost. This means reliability improvements that reduce failure frequency deliver ROI that far exceeds the initial investment cost.

ROI Calculation Example

Consider a mine with 24 haul trucks experiencing an average of 1.5 hoist cylinder failures per truck annually:

• Annual failures: 36 cylinders
• Average direct cost per failure: $45,000
• Average downtime per failure: 3 days
• Production value: $80,000 per day
• Total annual cost: 36 × ($45,000 + 3 × $80,000) = $10.26 million

Investing in upgraded cylinders that reduce failure frequency by 70%:

• Remaining failures: 10.8 cylinders annually
• Annual cost reduction: $7.18 million
• Upgrade cost premium: $12,000 per cylinder × 24 trucks × 2 cylinders = $576,000
• First-year ROI: 1,246%

Even with conservative assumptions, hydraulic cylinder reliability mining improvements deliver exceptional returns. This economic analysis demonstrates why reliability investment should be a top priority for mining operations.

Implementation Roadmap

Implementing a comprehensive reliability improvement program follows a logical progression.

Phase 1: Assessment and Foundation (Months 1-3)

Current State Assessment: Audit current cylinder fleet condition, failure history, maintenance practices, and specification standards. Establish baseline failure rates and costs. Identify high-frequency failure modes and high-cost problem areas.

Standard Development: Develop standard cylinder specifications for each application type incorporating safety factor requirements, sealing system standards, rod coating specifications, and quality documentation requirements. Establish minimum acceptable standards that all new cylinder purchases must meet.

Failure Analysis Process: Implement standardized failure analysis procedures and train maintenance personnel. Establish the fleet reliability database and begin entering historical and current failure data.

Phase 2: Initial Improvements (Months 4-12)

High-Impact Upgrades: Identify the applications with highest failure cost impact. Implement specification upgrades for these applications first. Typically, haul truck hoist cylinders and excavator bucket cylinders deliver the highest ROI.

Condition Monitoring Pilot: Implement condition monitoring pilot programs on the highest impact equipment. Start with pressure monitoring and periodic vibration analysis. Develop baseline signatures and establish alarm thresholds.

Maintenance Procedure Updates: Update maintenance procedures incorporating best practices for cylinder inspection, wiper replacement intervals, and fluid maintenance. Train maintenance personnel on updated procedures.

Phase 3: Full Implementation and Optimization (Months 13-24)

Fleet-Wide Standardization: Roll out updated specifications across the entire cylinder fleet. Implement upgrade programs for existing standard cylinders where economically justified.

Full Condition Monitoring Deployment: Expand condition monitoring to all critical cylinders. Integrate monitoring data with equipment management systems for automated alarming and work order generation.

Continuous Improvement System: Establish formal continuous improvement processes. Regularly review failure analysis data, implement corrective actions, and verify effectiveness. Continuously refine specifications and maintenance procedures based on actual field performance.

Case Studies: Hydraulic Cylinder Reliability Improvement

Hypothetical Scenario: Gold Mining Operation Fleet Reliability Program

Challenge: A large gold mining operation with a fleet of 18 haul trucks, 8 excavators, and 12 loaders experienced chronic hydraulic cylinder reliability problems. The operation recorded 127 cylinder failures annually costing an estimated $17.8 million in parts and downtime. No systematic failure analysis was performed, and cylinders were treated as consumable items replaced on failure.

Cenbifyn Solution: We implemented a comprehensive hydraulic cylinder reliability mining improvement program beginning with a fleet audit and baseline failure analysis to document current failure rates and costs. Specification upgrades followed, implementing 4:1 safety factors, HVOF rod coatings, and multi-stage wipers across all new cylinder purchases. Additionally, we established a standardized failure analysis process for every failure event, launched a condition monitoring pilot program on haul truck hoist cylinders, and updated maintenance procedures to include scheduled wiper replacement and hydraulic fluid cleanliness targets.

Results: After 24 months, annual cylinder failures dropped to 38 — a 70% reduction. Total annual cost decreased to $4.7 million, representing $13.1 million in annual savings. The initial program implementation cost of $850,000 delivered 1,541% first-year ROI. The mine has since expanded the program to include all underground equipment as well.

Hypothetical Scenario: Coal Mine Roof Support Reliability Improvement

Challenge: An underground coal mine operating two longwall faces with 336 roof supports experienced approximately 350 cylinder failures annually. Failures were attributed to severe coal dust contamination overwhelming the single-stage wiper systems. Each failure required underground maintenance in confined spaces, creating significant safety exposure.

Cenbifyn Solution: We implemented a targeted hydraulic cylinder reliability mining improvement program centered on a triple-stage wiper system upgrade — metallic scraper, dual polyurethane wipers, and labyrinth seal — to address the severe coal dust contamination. Enhanced gland drainage design prevented dust accumulation at seal surfaces. In addition, electroless nickel rod coating improved corrosion resistance, structured failure analysis tracked failure modes and validated improvement effectiveness, and targeted training equipped underground maintenance personnel with proper inspection techniques.

Results: After 12 months, annual cylinder failures dropped to 42 — an 88% reduction. Underground maintenance hours decreased by approximately 1,800 hours annually, substantially reducing personnel safety exposure. Annual cost savings exceeded $3.7 million. The upgraded design became the corporate standard for all underground roof support cylinders.

Hypothetical Scenario: Copper Mine Excavator Reliability Optimization

Situation: An open-pit copper mine operating six 450-ton excavators experienced repeated structural cylinder failures. Fatigue cracking at the tube-to-end-cap weld joint caused 4-6 catastrophic failures annually, each resulting in 5-7 days of downtime.

Root Cause Analysis: Systematic failure analysis identified three contributing factors: inadequate 3:1 safety factor providing insufficient fatigue margin, improper weld geometry creating stress concentration points, and incomplete post-weld heat treatment leaving residual stresses. The combination created conditions ideal for fatigue crack initiation and propagation.

Cenbifyn Solution: We implemented a comprehensive reliability improvement starting with a cylinder redesign featuring a 5:1 safety factor and optimized weld joint geometry to eliminate the original stress concentration. Controlled post-weld heat treatment with temperature monitoring and documentation removed residual stresses from the manufacturing process. Furthermore, ultrasonic inspection verified all critical weld joints, a pressure monitoring system installed on all excavator cylinders provided early detection of developing problems, and annual borescopic inspection assessed internal cylinder condition throughout service life.

Results: After 30 months of operation with the redesigned cylinders and monitoring program, the mine recorded zero structural fatigue failures. Annual savings exceeded $4.5 million in avoided downtime. The condition monitoring program also identified five developing seal failures in early stages, allowing planned maintenance during scheduled shutdowns.

Frequently Asked Questions (FAQ)

Q1: What provides the largest reliability improvement for mining cylinders? A1: Rod coating upgrade from standard hard chrome to HVOF tungsten carbide or laser cladding typically delivers the single largest reliability improvement. Service life improvement of 2-5x is commonly achieved. Combined with multi-stage wiper system upgrade, these two changes typically reduce failure rates by 60-80% for most mining applications.

Q2: How much does improving reliability typically cost? A2: Upgrading to HVOF coating adds 20-30% to initial cylinder cost. Upgrading to laser cladding adds 40-60%. Multi-stage wiper systems add 5-10%. Safety factor increases add 10-20%. Total premium for heavy-duty specification typically ranges from 35% to 100% over standard industrial cylinders. However, this investment typically delivers ROI of 500% to 2,000% in the first year through reduced downtime and maintenance costs.

Q3: Can existing cylinders be upgraded to improve reliability? A3: Many existing cylinders can be upgraded to significantly improve reliability. Common upgrade options include rod re-coating with HVOF or laser cladding during overhaul, seal system upgrade to multi-stage wiper arrangements, gland modification adding drainage features, and accumulator integration for shock absorption. Structural limitations such as inadequate wall thickness typically cannot be economically corrected.

Q4: What condition monitoring technologies deliver the best value? A4: The highest value technologies are typically pressure monitoring providing quantitative data on internal condition and shock loads, periodic vibration analysis detecting mechanical looseness and fatigue cracking, regular rod surface inspection by trained maintenance personnel, and piston drift testing measuring internal leakage. The combination of these four methods detects the vast majority of developing failures at the symptomatic stage, allowing planned maintenance.

Q5: How do I justify reliability improvement investment to management? A5: The most compelling justification focuses on downtime cost reduction, which is typically 5-20x direct cylinder cost. Calculate current annual failure costs, estimate expected reduction from proposed improvements, and calculate ROI. Include additional benefits such as reduced safety exposure, improved equipment availability, and reduced maintenance labor. Most reliability improvement programs deliver ROI well above typical corporate hurdle rates.

Q6: What maintenance practices most impact cylinder reliability? A6: Three maintenance practices have disproportionate impact: maintaining hydraulic fluid cleanliness to ISO 14/11 or better, which directly reduces wear throughout the hydraulic system; scheduled wiper replacement before wear allows contamination ingress, preventing damage that would otherwise require complete cylinder overhaul; and regular rod surface washing to remove accumulated dust before it can cause abrasive wear. These three practices typically account for 60-70% of maintenance’s impact on cylinder reliability.

Q7: How long does it take to see results from reliability improvement programs? A7: Maintenance procedure improvements and condition monitoring implementation deliver results within 3-6 months. Specification upgrades deliver results as cylinders are replaced over time — typically 12-24 months for full fleet impact. Comprehensive programs combining all elements typically deliver 50% of projected savings within 12 months and 90% within 24 months.

Conclusion

Hydraulic cylinder reliability mining operations achieve requires systematic attention across specification, maintenance, monitoring, and continuous improvement. Cylinder reliability should not be treated as an unavoidable operating cost — it can be actively managed and dramatically improved with proven strategies.

The economic case for reliability investment is overwhelming. The cost of cylinder failure — particularly the indirect cost of lost production — dwarfs the incremental cost of proper specification and maintenance. Most mining operations can reduce cylinder failure rates by 50-80% through systematic improvement programs, delivering returns on investment that far exceed typical corporate requirements.

The implementation roadmap provides a practical approach to achieving these results. Start with assessment and foundation work, implement high-impact improvements on the most costly applications first, then systematically expand and optimize across the entire fleet.

As mining equipment continues to grow larger and production rates increase, hydraulic cylinder reliability will become even more critical. Operations that recognize this and invest in systematic reliability improvement will gain significant competitive advantage through higher equipment availability, lower operating costs, and improved safety performance.
