Asset Integrity Management (AIM)

We deliver comprehensive asset integrity management services aimed at ensuring the continued fitness, reliability, and safe operation of pipelines, facilities, and equipment throughout their service life.

Outcome:

Improved inspection effectiveness, reduced risk of failure, optimized maintenance planning, and extended asset life.

  • Corrosion Monitoring Location (CML) optimization
  • Advanced Non-Destructive Examination (NDE)
  • Risk-Based Inspection (RBI) development and support
  • Fitness-for-Service (FFS) assessments (API 579 / ASME FFS-1)
  • Deadleg identification, assessment, and management
  • Integrity-driven preventive and corrective maintenance support
  • Remaining life and degradation rate assessment
  • Life extension and integrity assurance studies
  • Development and implementation of Integrity Operating Windows (IOW)

Corrosion Control

We deliver practical and engineered corrosion mitigation solutions to control external and internal corrosion threats across asset systems.

Outcome:

Reduced corrosion rates, improved asset reliability, compliance with industry standards, and lower lifecycle costs.

  • Cathodic protection engineering (SACP & ICCP)
  • Coating and lining specification, inspection, and QA/QC
  • Corrosion monitoring systems (coupons, ER probes)
  • Materials selection and corrosion management strategies
  • CP surveys, audits, and performance assessments

Pipeline & Facility Inspections & Surveys

We provide specialized inspection and survey services to assess the condition and integrity of pipelines and associated facilities.

Outcome:

Early detection of coating defects, verification of CP effectiveness, targeted remediation, and improved pipeline integrity.

  • Close Interval Potential Survey (CIPS)
  • Direct Current Voltage Gradient (DCVG) surveys
  • Pipeline coating condition assessment
  • CP system performance evaluation
  • Data analysis, reporting, and anomaly prioritization

Materials & Corrosion Engineering

This ties design, operations, and mitigation together and is very credible for AIM-focused companies.

  • Materials selection and corrosion threat assessment
  • Internal corrosion assessment and modelling
  • Corrosion management plans (CMP)
  • Failure analysis and root cause analysis (RCA)
  • Corrosion allowance verification and life prediction
  • Detailed engineering design
