Applied Ultrasonics was hired to treat one of Noble Drilling's rigs in the North Sea, the Ton van Langeveld, an offshore drilling rig built in 1979 that had developed deep stresses from years of high demand work in the face of some the harshest operating conditions in the world. In the North Sea, a drilling rig takes a constant beating and welds are exposed to enormous stresses coupled with the corrosive saltwater environment.
Applied Ultrasonics uses a patented technology called, Ultrasonic Impact Technology (UIT) to treat a range of metals, removing weaknesses and reducing metal fatigue while extending the life of critical parts and structures.
Applied Ultrasonics' quick-reaction team was mobilized to treat welds inside and out on the cross bracing (the middle columns, K-joints, outer columns / chain lockers) using Applied Ultrasonics' PLC 05 portable equipment. The team got in, treated the high stress areas and got out with minimal time on the site, ensuring uninterrupted workflow while the Ton van Langeveld was in dry-dock.
Applied Ultrasonics' PLC 05 portable equipment was used to treat welds that were deep inside enclosed areas, thus imparting compressive stresses and stress relief in areas that are inaccessible by other methods. The results were successful in extending fatigue life by a factor of 6-8 while reducing overall downtime.
