Engineering Insight Through
Real Integrity
Challenges.
TES case experience highlights practical engineering thinking – operational context, engineering reasoning, multidisciplinary assessment, and lessons drawn from real infrastructure integrity challenges.
Case experience on this page draws upon the accumulated engineering knowledge of TES personnel and technical collaborators developed through previous roles and professional involvement – not all cases represent TES Canada direct project delivery.
Real Integrity Challenges
Rarely Fit Simple
Service Categories
The most technically demanding integrity situations are defined by their complexity – not by which service line addresses them. Aging infrastructure, degradation mechanism interactions, data uncertainty, operational constraints, and repair-or-run decisions rarely arrive neatly packaged within a single discipline.
TES case experience illustrates how engineering thinking integrates across disciplines – and why the reasoning behind an integrity decision matters as much as the decision itself.
Engineering Thinking Applied to Real Challenges
Multi-Phase CUI Integrity Management Program for LNG Facility Assets
TES Canada supported a Canadian LNG facility operator with a multi-phase CUI integrity management program, combining field inspection, risk-informed prioritization, a plant-wide CUI manual, and a digital reassessment tool to support sustainable integrity decisions.
Risk-Based Inspection Assessment for Pressure Safety Valves at a Canadian LNG Facility
TES Canada completed a pilot API 581 Part 5 RBI assessment for 60+ pressure safety valves at a Canadian LNG facility, ranking PSV risk and identifying opportunities to optimize inspection intervals and move toward risk-informed integrity management.
API 581-Based RBI Assessment for Pressure Vessels at a Canadian LNG Facility
TES Canada completed an API 581-based RBI assessment for eight pressure vessels at a Canadian LNG facility, supporting continued operation, inspection prioritization, and vessel-specific integrity plans while reducing unnecessary intrusive inspection.
Representative Leadership Experience: Large-Scale Pipeline Direct Assessment and LRUT Integrity Program
A TES Canada leadership team member previously led a major 3,700 km pipeline integrity program covering ECDA, ICDA, SCC direct assessment, LRUT screening, corrosion assessment, FFS, and long-term integrity planning for oil and gas assets.
Representative Leadership Experience: Large-Scale Digital Asset Integrity Program for Offshore and Onshore Oil Assets
TES Canada’s digital integrity capability is informed by leadership experience from a large-scale offshore program covering 170+ platforms, 3D modelling, inspection records, CML development, advanced NDT, and software-based integrity delivery.
API 579 Fitness-for-Service Assessment for Local Metal Loss in an Industrial Storage Tank
TES Canada’s team supported an API 579 fitness-for-service assessment for an industrial storage tank with metal loss. The work helped evaluate remaining integrity, inspection findings, and practical engineering options for continued safe operation.
Multi-Client CWB Retained Welding Engineering Support for Canadian Fabrication Companies
TES Canada provides retained welding engineering support for clients requiring CWB-related guidance, procedure review, fabrication support, and technical interpretation. The service helps organizations maintain compliant, practical, and responsive welding engineering oversight.
Representative Leadership Experience: Offshore Risk-Based Inspection and Fitness-for-Service Program
TES Canada’s key personnel bring prior experience in RBI and fitness-for-service programs for offshore production platforms. The work involved integrity assessment, inspection planning, corrosion evaluation, and risk-based prioritization for complex upstream assets.
Common Themes Across
Integrity Engineering Challenges
These engineering themes recur across different industries, infrastructure types, and operating environments. They define the types of integrity challenges that require more than standard inspection delivery – they require engineering thinking.
Aging Infrastructure
Assets operating beyond design life – with degradation patterns and inspection demands that original programme assumptions cannot adequately address.
Inspection Prioritisation
How to direct limited inspection resources toward the equipment and mechanisms that actually carry risk – rather than defaulting to schedule or compliance criteria.
Hidden Degradation
Damage mechanisms that develop in locations or at rates that conventional inspection strategies are not structured to detect – until consequences emerge.
Repairability Decisions
Engineering assessment of repair vs. run under operational constraints – balancing technical safety, production continuity, and documented rationale.
Risk-Informed Planning
Structuring integrity programmes around actual risk rather than compliance minimums – and maintaining that alignment as operating conditions evolve.
Multidisciplinary Assessment
Integrity challenges that require simultaneous application of corrosion engineering, NDT, structural assessment, and operational context to reach a defensible conclusion.
Data Uncertainty
Making sound engineering decisions when inspection data is incomplete, inconsistent, or requires engineering context that the data alone cannot provide.
Operational Constraints
Engineering that must function within real operational realities – access limitations, production schedules, regulatory notification, and cost constraints.
