Splash Zone Inspection

The splash zone – the area immediately above and below the mean water level – has long been a major concern to both design and corrosion engineers of offshore installations. This vulnerable area faces corrosion from both the atmosphere and the sea. Because it is just above the waterline, it also can suffer from impact and abrasion and is one of the most challenging offshore inspection areas.

Splash Zone Inspection

TSC Subsea’s MagCrawler™ system has shown significant capability for in-depth analysis of corrosion mapping and other failuress in splash zone inspections. The MagCrawler is deployed via ROV or basket or can be launched directly from the deck. Capable of carrying an array of inspection technologies, this robust inspection method is the smart choice for splash zone integrity inspections.

Typical applications include:

  • Jackets and subsea structure welds
  • Conductors and guides
  • Bridge supports
  • Jetty piles
  • Risers
  • Monopiles

Subsea Phased Array (SPA)

TSC Subsea were challenged to investigate sand erosion concerns on subsea structure piping off the coast of Western Australia. The inspection campaign covered multiple assets including Pipeline End Manifold (PLEM), tie in spool and subsea cooling skid in the Halyard Field and a PLEM in the East Spar Field.
