Corrosion Surveys & Diagnostic Studies
CORPS performs high-precision field surveys to evaluate corrosion health, assess coating integrity, and detect stray current interference along buried and submerged cross-country pipelines and plant networks.
- Close Interval Potential Surveys (CIPS / CIS): Continuous pipe-to-soil potential profiling under on/instant-off conditions.
- Direct Current Voltage Gradient (DCVG): High-resolution pinpointing and sizing of microscopic coating defects.
- AC & DC Stray Current Interference Surveys: Detection and mapping of high-voltage powerline and traction current influences.
- Multi-Layer Soil Resistivity Surveys: Four-pin Wenner and electromagnetic conductivity profiling.
- Offshore Pipelines Corrosion Surveys: Subsea trailing wire potential profiling and offshore platform CP surveys.
External Corrosion Direct Assessment (ECDA)
Our structured 4-step ECDA methodology complies with NACE SP0502 standards, enabling operators to identify and proactively remediate external corrosion threats without taking pipelines out of service.
- Pre-Assessment: Historical operational data gathering, pipeline records integration, and feasibility analysis.
- Indirect Examinations: High-density aboveground surveys including CIS, DCVG, ACVG, soil studies, resistivity, depth of cover, and sub-meter GPS locating.
- Direct Examination: Bell-hole excavations, visual coating inspection, pitting measurements, Microbiologically Influenced Corrosion (MIC) testing, and root cause failure analysis.
- Post-Assessment: Remaining pipeline life modeling, re-assessment interval calculations, and long-term remediation planning.
Internal Corrosion Direct Assessment (ICDA)
CORPS delivers advanced ICDA programs for gas, liquid, and multiphase pipelines in accordance with NACE standards to predict, locate, and prevent internal corrosion in critical assets.
- Pipeline System Evaluation: Flow modeling, fluid composition analysis, and critical inclination angle identification.
- Engineering Calculations & Modeling: ICDA process optimization and predictive modeling of multiphase corrosivity.
- Laboratory Fluid & Solid Analysis: Chemical sampling and analysis of extracted liquids, gases, scales, and corrosion solids.
- Microbiologically Influenced Corrosion (MIC): Laboratory culturing, testing, and bacteriological threat assessment.
- Corrosion Monitoring & NDT: ER probes, corrosion coupons, and non-destructive ultrasonic thickness testing.
- Chemical Treatment & Pigging: Cleaning pig programs and optimized application of corrosion inhibitors and bactericides.
AC & DC Interference Services
Interference from high-voltage AC power transmission lines, co-located foreign pipelines, and DC electrified transit systems can cause rapid metal loss and safety hazards. CORPS provides comprehensive diagnostic modeling and engineered mitigation.
