CAnDU Anti Fouling

Cuprion CAnDU Anti-Fouling

AN OVERVIEW

Bio-Fouling of water intake pumps and pipework can be a major problem, causing expensive equipment damage and pipework blockages, leading to shut down of vital seawater supplies.

To address these issues Cathodic Protection Co. Limited has developed a deck mounted anti-fouling system, which can use the existing delivery pipework from a chlorine anti-fouling system. This latest version from Cathodic is known as the CAnDU™ system. It features a modular design which can be expanded to suit different pump capacities, allowing manufacturing costs to be minimised. The result is an affordable system which will provide complete anti fouling protection to the pump and significant savings to the operator.

Maintenance Managers would consider any remedial actions involving pipe section removal, repair, cleaning and re-installation as major refurbishment work on any operating offshore facility.

Cathodic Protection Co. Limited has developed the Cuprion™ range of anti-fouling systems to protect submerged pumps, seawater intakes and associated pipework against marine growth.  Originally the Cuprion™ system was developed and utilised for North Sea application during the early 1970’s.  Today the system is specified for use on offshore platforms and costal seawater intakes worldwide by many of the major Oil & Gas offshore operators.

The new anti-fouling system is designed to protect submerged pumps from marine growth.  A derivative of the proven Cuprion™ anti-fouling system, this latest version has been developed as a direct replacement for existing hypochlorite and other chlorine based anti fouling systems used on offshore platforms and jetties.

Corrosion problems and poor reliability are issues which are often reported by operators of chlorine based anti fouling systems.  The Cuprion™ system in contrast is non-corrosive and requires no routine maintenance. Protection to the pump is provided by copper and aluminium ions which are generated by the electrolysis of solid electrodes.
