Cover Story: Cathodic protection (CP) is critical to the long-term deployment of steel monopiles used to support offshore wind turbines. The application of CP to internal surfaces has created byproducts which alter seawater chemistry and may accelerate corrosion. One option for this is to incorporate perforations into the design to enable seawater flow. This could also create habitats for marine organisms and contribute to the sustainability goals of the industry. This research investigated aluminum sacrificial anode and impressed current CP applied to the inside of sealed and perforated steel pipes on the basis of current demand, internal water chemistry, and marine life. The CP systems inside the perforated pipes effectively controlled corrosion and behaved similarly to external systems. Marine organisms grew inside the perforated pipes, demonstrating the ability to create habitats for marine life. View this paper
