Engineering Services

A: Quest Integrity performs comprehensive Failure Analysis to help operators understand the root cause of pipeline or equipment failures and prevent recurrence. The process combines field evidence collection, laboratory examination, metallurgical testing, and engineering assessment to identify the key technical factors that contributed to the incident.

Typical deliverables include a clear cause-and-effect evaluation, detailed photographs and test results, materials characterization, fracture and corrosion analysis, and a root-cause determination supported by industry-recognized methodologies. Each report also provides practical recommendations for mitigation, design improvements, operating changes, or maintenance strategies.

The outcome is a thorough, defensible assessment that equips operators with actionable insights to improve safety, reliability, and long-term asset performance.

A: Fitness-for-Service (FFS) and Remaining Life assessments evaluate whether a pipeline with corrosion, deformation, or other imperfections can continue to operate safely. Using industry-recognized engineering methods, Quest Integrity determines the pipeline’s current structural integrity, how defects may grow over time, and the safe operating limits of the asset.

For operators, these assessments provide actionable insight into which anomalies require immediate repair, which can be monitored, and how long the pipeline can continue operating reliably. The result is improved safety, optimized maintenance planning, and confident, defensible integrity decisions, helping asset owners reduce risk while maximizing operational uptime.

A: Integrity Optimization helps operators maximize the value and service life of their pipelines by using data-driven insights to prioritize maintenance where it delivers the greatest impact. By combining inspection results, engineering assessments, and risk-based planning, Quest Integrity identifies the safest and most efficient path for managing corrosion, defects, and operational threats over time.

This approach reduces uncertainty, prevents unexpected failures, and ensures resources are focused on the highest-risk areas. The result is improved safety, extended asset life, and smarter long-term integrity management, helping operators operate confidently while minimizing downtime and lifecycle costs.

A: Quest Integrity offers a full suite of Metallurgical and Materials Engineering services to help operators understand why damage occurs and how to prevent recurrence. Our experts provide material characterization, failure analysis, corrosion mechanism identification, weld and heat-affected zone assessment, and Fitness-for-Service support.

These services are recommended whenever pipeline, vessel, or well components show unexpected degradation, when historical damage trends need validation, or when operators are planning repairs, life-extension projects, or changes in operating conditions. By combining advanced laboratory analysis with engineering insight, we deliver clear, defensible guidance that supports safe, reliable, long-term asset performance.

Metallurgical & Materials Engineering services include:

• Failure & fracture analysis (root cause, brittle/ductile behavior, fatigue, SCC, HIC/SOHIC)
• Metallography & microstructural evaluation (welds, HAZ, heat treatment verification)
• Mechanical testing (tensile, impact, hardness, fracture toughness, bend tests)
• Corrosion & environment assessments (CO₂/H₂S corrosion, MIC, galvanic, pitting/crevice, EAC)
• Materials selection & specification (line pipe, risers, CRA cladding/liners, elastomers, coatings)
• Welding & fabrication support (WPS/PQR development, procedure qualification, welder qualification, repair welding)
• Fitness-for-Service inputs (material properties, defect characterization, fracture mechanics parameters)
• Failure prevention & life extension (residual life, degradation mechanisms, heat treatment/PWHT guidance)
• Coatings, linings, and CP review (compatibility, defect causes, performance optimization)
• Laboratory testing & characterization (SEM/EDS, microhardness mapping, chemical analysis)

Recommended when:

• A failure, leak, or anomaly requires root-cause determination and corrective action
• ILI or inspection indicates cracking, hydrogen damage, or accelerated corrosion
• Material upgrades or design changes are being considered (new environments, higher pressures/temperatures, sour service)
• Repair planning requires weldability, procedure, or toughness validation
• Regulatory or compliance requirements demand defensible materials evidence for audits or incident reviews
• Remaining life or Fitness-for-Service assessments require accurate material properties or fracture mechanics inputs
• Coating/CP performance is uncertain, or microbiologically influenced corrosion (MIC) is suspected

Outcome: Clear, defensible materials insights that reduce uncertainty, prevent recurrence, and support safe, cost-effective integrity decisions across the asset lifecycle.

A: Pipeline Integrity Engineering helps operators meet regulatory requirements and manage risk by transforming inspection data and operating information into defensible engineering decisions. Quest Integrity’s approach aligns assessments with applicable codes, standards, and regulatory expectations, ensuring operators have the documentation, traceability, and technical justification required for audits and compliance reviews.

By combining Fitness-for-Service methods, corrosion growth analysis, risk ranking, and remediation planning, our integrity engineers help identify the highest-priority threats, justify safe operating limits, and support long-term integrity programs. This structured, engineering-led approach reduces uncertainty, strengthens regulatory compliance, and supports safe, reliable, and cost-effective pipeline operations.

A: Quest Integrity supports the Power and Utilities sector with a suite of advanced inspection and engineering services designed to enhance safety, reliability, and asset performance. We help operators assess critical components such as boilers, turbines, piping systems, heat-recovery units, and high-energy steam lines using high-resolution inspection technologies and industry-recognized assessment methods.

Our services include inline inspection of complex piping, remaining life evaluations, Fitness-for-Service assessments, materials and metallurgical analysis, and failure investigations, all aimed at preventing unplanned outages and optimizing maintenance programs. By delivering clear, actionable insights, Quest Integrity helps utilities operate more safely, extend asset life, and make confident decisions across their power generation and distribution infrastructure.

A: Quest Integrity provides comprehensive Storage Tank Integrity Assessment Solutions designed to help operators ensure safe, compliant, and reliable tank performance. Our services combine advanced inspection methods with engineering evaluations to identify corrosion, settlement, structural issues, and risk factors across aboveground storage tanks.

These solutions typically include external and internal tank inspection, floor and shell assessment, corrosion mapping, settlement and geometric analysis, remaining life calculations, and Fitness-for-Service evaluations aligned with industry standards. We also provide repair recommendations, compliance documentation, and long-term integrity planning to support safe operation and regulatory readiness.

The result is a clear, defensible understanding of tank condition, enabling operators to make informed maintenance decisions while maximizing asset longevity and safety.

A: Structural and Mechanical Integrity Consulting helps operators identify issues early and take decisive action by combining targeted inspections with engineering analysis and risk-based decision-making. Quest Integrity evaluates loads, materials, welds, supports, vibration, corrosion, and fatigue to pinpoint failure drivers and recommend practical mitigation strategies.

What we do:

• Risk-based assessments (RBI, FMEA, RCM): Identify high-consequence components and prioritize actions
• Advanced analysis: Finite element analysis, Fitness-for-Service, vibration and fatigue evaluations, and remaining life assessments
• Degradation diagnostics: Corrosion and wall thinning, cracking (SCC, fatigue), creep, misalignment, foundation and settlement effects
