Cathelco systems for Chinese newbuilds
The biggest order is from New Times Shipbuilding for ten 33,000dwt chemical tankers being built for Jo Tankers of Norway. The vessels will be fitted with Cathelco’s Quantum impressed current cathodic protection (ICCP) system to protect hulls against corrosion. The aft-only systems consist of hull-mounted anodes and reference electrodes connected to a thyristor control panel.
“One of the advantages of the Quantum system is that the control panel stores comprehensive information about the performance of the system. said Adam Rogers, sales manager at Cathelco. “This can be downloaded to a USB stick and emailed to Cathelco for analysis, avoiding the need for completing and returning paper log sheets.”
Installation of the ICCP system will be made easier by the use of C-Max anodes, which are lighter and more compact than conventional anodes and provide a relatively large current output from a small surface area. They are designed to be replaceable by divers, without the need for drydocking. The tankers will also be fitted with Cathelco seawater pipework anti-fouling systems to protect engine cooling lines and auxiliary equipment against blockages caused by barnacles and mussels.
Eight 82,000dwt bulk carriers planned for construction for Norwegian company Klaveness Shipping at Jiangzu New Shipyard in Yangzijiang will be equipped with forward and aft ICCP systems. Two Quantum control panels will operate in a ‘master’ and ‘slave’ configuration with the whole system controlled from the aft panel. The installation package for the tankers includes the provision of Cathelco seawater pipework anti-fouling systems.
Jiangzu New Shipyard is also building four 64,000dwt bulk carriers for German owner Peter Dohle, which will feature forward and aft Quantum ICCP and seawater pipework anti-fouling systems.
Two anchor handling tug supply (AHTS) vessels being built for Pacific Crest by Nantong Tongshun, with delivery scheduled for July and August, will also house Cathelco seawater pipework systems installed in four seachests.
