FPSO Caisson NDT Inspections

The mini-ROV Class Survey System (CSS) was used to inspect an area of coating breakdown around a discharge caisson during an FPSO in water hull survey.

The objectives of the scope was to quantify the extent of the damaged coating using visual and ultrasonic thickness (UT) NDT data.
The NDT and visual data captured gave the class surveyor the data they needed to approve the UWILD. The ROV surveyed 12 caissons without any isolations or disruption to operations. Two active caissons hadn’t been inspected on two previous UWILD diving campaigns (over 10 years) because it was too dangerous to access the area with divers. The ROV system also captured HD video, cathodic protection measurements and high pressure blasted the weld seams and coating for close visual inspections.
