ESPOO, Finland – Evac subsidiary Cathelco is supplying a marine growth prevention system to a new multi-purpose vessel under construction at the Uzmar shipyard in Turkey for Kuwait Oil Co.
The 60-m (197-ft) long vessel, due to be delivered later this year, will be equipped for towing services, area surveillance, offshore fire-fighting, logistics support and search and rescue around Kuwait and in international waters.
To protect the pipework against marine growth and corrosion, Cathelco will provide copper and ferrous anodes installed in five sea chests, connected to a control panel.
The copper anodes will produce ions which should prevent the larvae of barnacles and mussels from settling, forming blockages in engine cooling and firefighting systems.
At the same time, the ferrous anodes will produce ions to create a protective coating on the internal surfaces of pipes.
The concentrations of copper ions are around 2 parts per billion, sufficient to prevent marine growth from settling, but with no effect on the wider marine environment after discharge, Cathelco claimed.
