Abstract

An anode structure (1) for connection to an offshore foundation. The body (2) of the offshore foundation has an anticorrosion coated surface region (7) and an exposed surface region (8) without an anticorrosion coating. The anode structure (1) comprises one or more anode elements (5) formed of a material having a more negative electrode potential than the body of the offshore foundation, and an electrically conductive frame (3,4,6) for supporting the one or more anode elements (5). When the frame is attached to the offshore foundation (2), one or more electrical contact formations (9) provided on the frame contact the exposed surface region (8).
