Ship Deck Pulsed Eddy Current Array Solution
A seven-channel pulsed eddy current array solution maps corrosion in steel ship decks through floor coverings while vessels remain in service.
Product overview
The Ship Deck Pulsed Eddy Current Array Solution assesses corrosion in structural steel deck plates without removing the flooring. Designed for maritime structures, mainly ships, it provides radiation-free inspection and compartment-wide corrosion mapping while the vessel remains in service.
The PECA-7CH-SM probe uses an array of seven pulsed eddy current sensors to inspect a 178 mm (7 in) swath in one pass. It supports inspection through floor coverings up to 38 mm (1.5 in) thick, with dynamic scanning speeds up to 150 mm/s (6 in/s), depending on deck plate thickness. A complementary single-element PEC probe provides access to confined areas using a compact body and rear-mounted clip-on encoder port.
Operators can work standing up with the quick-release carbon fiber telescopic pole or manipulate the probes directly with an ergonomic clip-on handle. SurfacePro3D reporting software overlays PEC C-scan data on 2D or 3D models of inspected structures, allowing array and single-element results to be combined into one report that contextualizes corrosion location and severity.
Key capabilities
Seven-channel array
Seven sensors provide 178 mm (7 in) coverage in a single pass for productive steel deck corrosion assessment.
Through-floor inspection
The array probe inspects steel deck plates through floor coverings up to 38 mm (1.5 in) thick.
In-service assessment
Radiation-free inspection produces a map of inspected compartments while the vessel remains in service.
Encoded dynamic scanning
A removable clip-on encoder enables scanning up to 150 mm/s (6 in/s), depending on deck plate thickness.
Restricted-access coverage
The single-element PEC probe combines a compact body with a rear encoder port for inspection in restricted-access areas.
Standup operation
The lightweight carbon fiber telescopic pole provides quick-release probe attachment and extends up to 2 m (6.5 ft).
Ergonomic handling
The clip-on handle helps keep the operator’s fingers clear of surrounding walls and obstructions.
Combined corrosion reporting
SurfacePro3D combines array and single-element PEC data in reports with C-scans overlaid on 2D or 3D structural models.
