Abstract

Assembly for the cathodic protection of a from galvanic corrosion suffering active component, which transports corroding medium, within a steel tube or casing containing a corroding medium. A plurality of anodes is equally distributed across the annular gap, while avoiding that these anodes are galvanically contacting the active component, e.g. pump, and one or more of the casing and tube or other component within the casing, other then through the corroding seawater, and a switching galvanic circuit. These anodes are suspended from a riser contained within the casing and providing the extension of the active component.
