Conceptual Sacrificial Anode Cathodic Protection Design for offshore wind monopiles

Abstract The design and implementation of a cathodic protection system for offshore steel monopiles used to support wind turbines are required to protect them from corrosion. This paper uses the recommended practice DNVGL-RP-B401-Cathodic Protection Design to demonstrate the step-by-step sacrificial anode cathodic protection system design of an offshore monopile located off the coast of Massachusetts. It compares the requirements for coated and uncoated structures and discusses the other factors that need to be taken into consideration.
