Overview AISUS was engaged by a North Sea offshore operator to undertake external cleaning and Pulsed Eddy Current Testing (PECT) inspection of two 6″ OD risers through the splash zone. The project presented several challenges, including restricted access, the presence of heavy marine growth and 50 mm thick passive fire protection (PFP) coating. To overcome […]

Overview AISUS was engaged to undertake a combined cleaning and Ultrasonic Testing (UT) Inspection on a Norwegian offshore platform jacket leg. The external scope included cleaning, visual and UT inspections through the splash zone, on two 2 metre width sections of the jacket leg. Time of Flight Diffraction (ToFD) inspection was also carried out on […]

Overview AISUS delivered internal visual, cleaning, and ultrasonic thickness (UT) inspection of a seawater lift caisson on an offshore platform in the Dutch Sector. The project highlighted AISUS’ ability to mobilise at short notice to global locations. The inspection equipment was requested on a Thursday, mobilised by the following Tuesday, and the AISUS team was […]
