Challenge

Abu Dhabi Marine Operating Company (ADMA-OPCO) is a major producer of oil and gas from the offshore areas of Abu Dhabi in the United Arab Emirates. ADMA-OPCO operates multiple barge-type offshore platforms constructed on caisson legs. Previously, internals of the platform caisson legs were left uncoated and filled with biocide-treated water and protected using suspended sacrificial anodes. Over time the anodes depleted and an alternative environmentally friendly method of protecting caisson legs was recommended.

Application
VpCI®-337 BD was sprayed in the caisson legs to stop bio-growth, VpCI®-609 S was then fogged in to the void space to counter dead volume of water at the bottom. Custom manufactured strips of Cortec’s Ecopouch® were then suspended from the top side for additional protection.

Conclusion
After two years, the pilot was deemed a success and Cortec® VpCI® was proven to effectively mitigate corrosion in an offshore environment by reducing the corrosion rate in the protected leg Vs the control by 584%.
