Bottom Pit Inspection

Bottom Pit Inspection evaluates the extent of pitting corrosion on tank and hull bottom structures. Using gauges or ultrasonic devices, inspectors record pit size, depth, and distribution for corrosion management.

Technique capability:

  • Detects localized corrosion and pitting in tank bottoms.
  • Provides pit depth and mapping for structural evaluation.
  • Supports renewal planning and steel weight estimation.
  • Essential for compliance with classification survey requirements.
