Marine Drilling Riser

Advanced Inspection Services


As inspection specialists, we work with OEM’s, rig owners & repair and maintenance facilities delivering quick and accurate inspection of marine drilling riser wall thickness, weld integrity and riser fasteners - without removing buoyancy or stripping components.


Our compact tool design enables fast and easy to set up, eliminating large, complicated tool packages, that are difficult to transport and operate.

Saving costs and time with innovative integrated inspection of your drilling riser system. This is achieved by the elimination of complex removal of the buoyancy, coatings & disassembly of the riser.
