Robotic Arrays

LIZARD LP180SR robotic subsea probe

LP180SR

Subsea nodal weld eddy current probe for robotic inspection with right-angled (90°) version available. Features 6 array pairings with 8 mm lift-off and software-selectable interrogation.

The LP180SR is a subsea nodal weld eddy current probe for robotic inspection of medium to large ferritic welds, with a right-angled (90°) version available. Its array design inspects the HAZ, weld toe, and cap in a single pass and accommodates offshore nodal joints with up to 30° connection tolerance. Featuring 6 array pairings (6 Bx, 6 Bz) across two sensor faces, software-selectable interrogation minimizes handling and inspection time. Each active face provides 8 mm lift-off capability with independent lift-off indicators, enabling inspection through most coatings. A hard-wearing protective array, threaded mounts, and a galvanised aluminium housing make the LP180SR ideal for harsh subsea environments.

LIZARD LP170SR robotic subsea probe

LP170SR

Subsea nodal weld eddy current probe for robotic inspection of medium to large ferritic welds. Features 7 array pairings with 8 mm lift-off and software-selectable interrogating faces.

The LP170SR is a subsea nodal weld eddy current probe designed for robotic inspection of medium to large ferritic welds. Its array configuration inspects the HAZ, weld toe, and cap in a single pass and is optimized for offshore nodal joints with up to 30° connection tolerance. Featuring 7 array pairings (7 Bx, 7 Bz) with software-selectable interrogating faces, it minimizes mechanical handling and inspection time. Each active face offers 8 mm lift-off capability with independent lift-off indicators, enabling inspection through most coatings. A hard-wearing protective array, threaded mounts, and galvanised aluminium housing make the LP170SR ideal for harsh subsea and offshore environments.
