Title (EN) CATHODIC PROTECTION FOR OFFSHORE WIND TURBINE STEEL SUPPORT STRUCTURES
(FR) PROTECTION CATHODIQUE POUR STRUCTURES DE SUPPORT EN ACIER D'ÉOLIENNES EN MER
Abstract:
(EN) Disclosed is a support system (100) for supporting an offshore wind turbine comprising a steel support structure (180) for supporting the offshore wind turbine and a cathodic protection system (101-105) configured to protect the steel support structure from corrosion. The cathodic protection system comprising one or more galvanic anodes (101) arranged in connection with the steel support structure and a first electrical connection (102) electrically connecting the one or more galvanic anodes to the steel support structure. This allows the steel support structure to be polarized by the electrons flowing from the one or more galvanic anodes to the steel support structure. The first electrical connection is an adaptable electrical connection that can change the rate of electrons flowing from the one or more galvanic anodes to the steel support structure and thereby change the polarization of the steel support structure.
(FR) L'invention concerne un système de support (100) destiné à soutenir une éolienne en mer, ledit système comprenant une structure de support en acier (180) pour soutenir l'éolienne en mer et un système de protection cathodique (101 à 105) conçu pour protéger la structure de support en acier contre la corrosion. Le système de protection cathodique comprend au moins une anode galvanique (101) agencée en connexion avec la structure de support en acier et une première connexion électrique (102) qui relie électriquement l'anode galvanique à la structure de support en acier. Ceci permet à la structure de support en acier d'être polarisée par les électrons s'écoulant depuis l'anode galvanique vers la structure de support en acier. La première connexion électrique est une connexion électrique adaptable qui peut modifier le débit d'électrons s'écoulant depuis l'anode galvanique vers la structure de support en acier, et ainsi modifier la polarisation de la structure de support en acier.
