Monitored Infrastructure Categories

Petroleum-support infrastructure comprises numerous interconnected systems and components, each subject to different operational stresses and environmental influences. PetroSentinel monitors eight primary infrastructure categories across varied operational environments.

Storage Tanks

Primary fuel containment vessels and storage systems

Above-Ground Storage Tanks (AST)

  • External shell condition and coating integrity
  • Seam and weld joint inspection
  • Support saddle and mounting assessment
  • Corrosion patterns and rust development
  • Roof structure and vent system condition
  • Level gauge and valve housing integrity
  • Foundation stability and settlement
  • Secondary containment berm status

Underground Storage Tanks (UST)

  • Fill and vent pipe condition (accessible elements)
  • Tank top and manway integrity
  • Spill bucket condition assessment
  • Cathodic protection system markers
  • Groundwater monitoring well status
  • Overfill protection equipment
  • Access point and seal condition
  • Surface indicators and leak detection

Key Observation Areas

Tank monitoring focuses on protective coating effectiveness, structural integrity indicators, connection point condition, and environmental exposure effects. Long-term pattern recognition includes corrosion progression rates, settlement trends, and coating system degradation timelines.

Pipeline Systems

Fuel transfer lines and distribution networks

Above-Ground Piping

  • Pipe surface condition and coating status
  • Support bracket integrity and alignment
  • Connection and flange condition
  • Valve body and stem assessment
  • Expansion joint condition
  • Insulation wrap integrity (where present)
  • Corrosion at supports and contact points
  • Vibration damper condition

Underground Piping (Accessible Points)

  • Above-grade transition zone condition
  • Exposed sections at manholes/vaults
  • Cathodic protection test stations
  • Surface indicators of subsurface issues
  • Trench settlement and surface disturbance
  • Access point integrity
  • Leak detection system markers
  • Ground movement effects on alignment

Key Observation Areas

Pipeline observation emphasizes support point condition (where stress concentrates), connection integrity, coating effectiveness, and effects of ground movement or settlement on alignment. Underground sections monitored through accessible points and surface indicators.

Cable Runs

Conduit systems, cable trays, junction boxes, weatherproof enclosures, grounding systems

Access Platforms

Catwalks, ladders, stairs, railings, safety gates, non-slip surfaces, corrosion protection

Utility Connections

Water lines, drainage systems, electrical services, communications, monitoring equipment

Common Infrastructure Issues

Frequently observed patterns across petroleum infrastructure categories

Coating Failure

Progressive breakdown of protective paint and coating systems, particularly at edges, corners, and high-exposure surfaces. Accelerated in UV-intense or chemically harsh environments.

Corrosion Development

Rust formation and metal degradation at moisture accumulation points, dissimilar metal junctions, and areas with compromised protective systems. Rate varies by environmental exposure.

Joint Degradation

Seal and gasket deterioration at connection points, flanges, and access openings. Compression set loss, material hardening, and crack development over operational timelines.

Foundation Movement

Settling, heaving, or shifting of foundations and support bases. Causes misalignment, connection stress, and structural loading changes. Seasonal patterns common in freeze-thaw zones.

Vibration Damage

Loosening of fasteners, fatigue cracking, and wear at connection points from operational vibration. Most pronounced near pumps, compressors, and high-flow piping systems.

Weather Degradation

Cumulative effects of UV exposure, temperature cycling, moisture, and wind. Material embrittlement, surface chalking, crack formation, and accelerated aging in high-exposure locations.
