New methods for survey and monitoring of cathodic protection systems for offshore platforms and pipelines

Corrosion has long been one of the biggest problems in the maritime, oil and gas industries. Corrosion not only cause high repair costs, but also to stop production at the time of repair and safety issues are the enormous damage it creates. Construction and operation of offshore production facilities is tremendously expensive. The consequences of anoffshore corrosion failure can be devastating. For these reasons, cathodic protection has become a universally appliedtechnique for mitigating corrosion on subsea pipeline and production facilities. Newly developed survey methods,combined with innovative design software and low cost hardware, are helping take the pain out of asset life extension for many operators worldwide. The purpose of this paper is to present an overview of subsea cathodic protection and corrosion control survey techniques in use today for monitoring and maintenance of offshore pipelines and platforms
