Beaudrey - Cathodic Protection Systems

The anodes are located so as to spread the protection of the machine evenly; BEAUDREY’s extensive experience is the key to a good design. The anodes, generally made from an aluminium alloy, are sized to protect the immersed area of the machine for a chosen duration (in practice from 6 months to 3 years).

Anodes need to be changed at the end of their life, but otherwise, the system is maintenance-free, very efficient and has no limitations induced by the type of material to be protected.

BEAUDREY works in association with a world-wide, reputed specialist.

The screens have some added features to suit the system. Anodes are located after careful study, to induce a homogenous protection.   

Voltage control is achieved by reference anodes that feed the information to the control cabinet.          

The anodes are chosen to suit each case. Control is fully automatic to accommodate tidal variations, evolution of the machine’s coating and growth without exceeding the voltage limits.     

Such a system needs a periodical specialist check-up to make sure there are no voltage excesses that may create serious corrosion rather than prevent it.    

Marine growth also interferes with the efficiency of the system.          

Great care must be taken to avoid stray current interference. When well designed and maintained, it gives remarkable results.
