Many older offshore structures are approaching the end of their design lives, however, for a number of reasons they are still required to operate beyond this time.

It has been found that if early intervention is undertaken, (before the structure’s anodes are consumed and depolarisation takes place) that significant savings in terms of anode material, vessel and diver intervention costs can be achieved.

ISIS can undertake studies which, in conjunction with CP inspection and current density analysis provide the Client with recommendations as to the continued efficiency of the installed CP system, as well as provide assistance with regard to the optimisation of any future anode retrofit programs.
