PEC is the cost effective solution to examine the Splash Zone area of raisers, caissons and offshore structures. The Splash Zone is the most aggressive corrosion area, see Figure.
PEC can easily measure through the riser coating and through the Monel protective metal layer detecting corrosion in the carbon steel section and through the marine growth layer.
Splash Zone area and marine growth on Offshore structures, Risers and Caisson.
Operation is generally performed with rope access and divers. To increase safety and to reduce risks, PEC measurements can be deployed remotely mounted on a riser tool. Different riser tools have been developed with diameters from 15” up to 50” in Australia and in Europe.
