Subsea and Underwater Structures

Pulse Eddy Current (PEC) Inspection for Subsea and Underwater Structures Offered by NDT AND PWHT SOLUTIONS PVT LTD – Global Leaders in Advanced NDT Services. Pulse Eddy Current (PEC) technology is revolutionizing the way subsea and underwater structures are inspected by enabling non-intrusive corrosion detection through marine growth, coatings, and insulation without the need for cleaning, surface preparation, or shutdowns.

At NDT AND PWHT SOLUTIONS PVT LTD, we bring the power of PEC to the most challenging underwater environments, offering safe, efficient, and high-accuracy inspection for subsea pipelines, caissons, conductors, riser supports, and mooring components.

Why PEC for Subsea and Underwater Integrity?

Subsea structures are at constant risk of corrosion under marine growth (CUMG) and coatings, especially in the splash zone, tidal zone, and deepwater environments. Traditional ultrasonic or visual techniques often require marine growth removal, diver intervention, and high downtime.

PEC changes the game by allowing through-coating and through-growth inspection using ROV-mounted or diver-assisted scanning tools. It reduces risk, increases speed, and provides valuable wall thickness data in real time.

Subsea and Underwater Structures

Typical Applications

✅Subsea pipelines and flowlines

✅ Caissons and conductors

✅ Mooring lines and chains

✅ Subsea risers and clamps

✅ Platform legs and structural nodes

✅ Marine riser supports and tie-ins.

Technical Capabilities

✅Works through: Marine growth, coatings, insulation, fireproofing

✅ No surface prep required

✅ Deployable via: ROV, diver-held tools, or manipulator arms

✅ Material compatibility: Ferromagnetic (e.g., carbon steel)

✅ Outputs: Wall loss profiles, thickness estimations, corrosion maps.

Benefits of PEC for Subsea Applications

✅ Non-intrusive & contactless – Safe for divers and equipment

✅ Works in turbid water – No visibility required

✅ No marine growth removal needed – Saves time & cost

✅ Fast scanning speeds – Wide coverage in minimal time

✅ Supports RBI and life extension planning

✅ Reduced downtime & logistics complexity.
