Protection Of Offshore Platform Caisson Legs With Vapour Phase Corrosion Inhibitors

Protection With Vapour Phase Corrosion Inhibitors Abu Dhabi Marine Operating Company Of Offshore Platform Caisson Legs is a significant manufacturer of oil and gas in the offshore areas of Abu Dhabi in the United Arab Emirates. This sizeable UAE oil company manages multiple barge-type off shore platforms constructed on caisson legs. Gas accumulation inside the restrained compartment around an offshore platform caisson leg caused a surge. The petrol was found to be hydrogen generated by the depleted anodes in the caisson leg. A study of the surge that was deadly made several recommendations, including elimination of the anodes, biocide treated water grit that had collected inside the caisson legs over two years. In the existence of among the most challenging rust environments on world is assisting gas and oil facilities to protect vital assets beyond their expected lives. Internals of the platform caisson thighs were left uncoated and full of biocide-handled water and protected using suspended anodes. Over time the anodes depleted and of protecting caisson thighs an alternate environmentally friendly method was urged. A successful pilot study was conducted to evaluate the use of the Vapor Phase Corrosion Inhibitors of a Cortec and the method was adopted for rectification of the difficulty. The final recommendation was rust management utilizing Vapor Phase Rust Inhibitor (VpCI®).
