Anode construction and method for deploying anode construction

Abstract

The invention relates to an anode construction comprising a frame with two or more anodes and being adapted to be used with an offshore installation for remote connection with the offshore installation through cable connections between anodes and offshore installation. The frame comprises a main part and at least one movable part mounted on the main part and adapted to be pivotable or slidable in relation to the main part, where one or more anodes are mounted in a fixed position on the main part and one or more anodes are mounted on the movable part. The main part has a bottom frame part and a top frame part and further at least two anode mounting columns between the bottom frame part and the top frame part, and where the fixed anodes are mounted on the anode mounting columns.
