Subsea and Underwater Structures
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.
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.
