Subsea Structures Inspection

Subsea Pipeline Inspection

The MEC-Combi PipeCrawler supports the inspection of smaller diameter subsea pipes, risers and caissons ranging from 6” to 16” for internal and external defects and wall loss.

The MEC-Combi PipeCrawler is a sophisticated self-crawling inspection tool designed to support the inspection and lifetime assessment of smaller diameter subsea assets like pipes, risers and caissons ranging from 6” to 16”, with deployment by ROV from a support vessel or by divers.

The MEC-Combi PipeCrawler combines the Magnetic Eddy Current fast scanning sensor array system with an Ultrasonic sensor unit to provide valuable data on the internal and external wall thickness. This advanced inspection system identifies localised defects and general wall loss. The fitted camera and light system supports a visualisation of the scan while the position encoder system enables its location on the inspection surface to be determined.

The MEC-Combi PipeCrawler enables the incorporation of selected advanced inspection techniques such as high resolution Ultrasonic mapping, Pulsed Eddy Current (PEC), laser triangulation system, camera system, etc to be used in combination to allow the different detection aspects of corrosion and general wall loss.

Key features of MEC-Combi PipeCrawler:

  • Capable of moving along the inspection surface on its own due to its hydraulic motors
  • Capable of remaining in stable contact with the inspection surface despite the turbulences and waves due to its integral buoyancy and magnetic system
  • Preparation of the inspection surface is less critical due to its electromagnetic technique

Key capabilities of MEC-Combi PipeCrawler:

  • High defect detection sensitivity
  • High inspection speed of up to 20m/min
  • Ability to detect both external and internal corrosion and defects
  • Ability to inspect at various subsea depths
  • Ability to inspect through surface coating, clad or painting
  • Minimal surface preparation prior to inspection, except for the removal of heavy marine growth

Together with Innospection's comprehensive reporting software, accurate and reliable inspection results are generated in real time. The advanced colour condition mapping report provides analysis of the internal and external defects in term of size, severity of wall loss and locations of defects and other occurrences.
