Cathelco has won an order to supply a seawater pipework anti-fouling system for a new FPSO which will be operated in the Cendor offshore oil field by Petrofac Malaysia.

The system will be installed on the MT Onozo, an Aframax tanker, which is being converted to an FPSO at the MHB yard in Pasir Gudang, Johor, Malaysia. After modification the vessel will be renamed the FPSO Cendor and deployed offshore Terengganu in West Malaysia.

Cathelco will be supplying the anti-fouling electrolysis tank system to protect seawater inlets and pipework against blockages caused by barnacles and mussels. The tank will be fitted with copper and ferrous anodes which are fed with an electrical current from a control panel.

The purpose of the tank is to dose seawater with copper ions which create an environment where fouling species larvae do not settle or breed. At the same time, ions from the ferrous anode help to maintain a protective oxide layer on the internal surfaces of pipes to suppress corrosion.

The dosed water will be distributed to intakes serving fire fighting pumps and ballast water pumps, plus machinery room and pump room seachests.
