    Cathelco wins orders from Chinese shipyards for their hull corrosion protection and seawater pipework anti-fouling systems

    Cathelco have won a succession of orders from Chinese shipyards for their hull corrosion protection and seawater pipework anti-fouling systems, the company said in its press release.

    The largest order has come from New Times Shipbuilding where a series of ten 33,000 dwt tonne chemical tankers are to be built for Jo Tankers of Norway.

    Each of the vessels will be installed with the latest Cathelco Quantum impressed current cathodic protection (ICCP) system to protect the hulls against corrosion. The aft only systems will consist of an arrangement 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. This can be downloaded to a USB stick and e-mailed to Cathelco for analysis, avoiding the need for completing and returning paper log sheets”, said Adam Rogers, sales manager at Cathelco.

    Installation of the ICCP system will be made easier by the use of C-Max anodes. These are lighter and more compact than conventional anodes, whilst providing a relatively large current output from a small surface area. They are also designed to be ‘diver’ changeable, enabling replacement to be carried out in the future without the need for drydocking.

    The Jo 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.

    Another order has come from Jiangzu New Shipyard in Yangzijiang where Klaveness Shipping of Norway has options on some of eight 82,000 dwt bulk carriers which are planned for construction.

    The size of the vessels means that they will be installed with forward and aft Cathelco ICCP systems to protect the hulls against corrosion. In these circumstances, the two Quantum control panels can operate in a ‘master’ and ‘slave’ configuration with the whole system controlled from the aft panel.

    “Engineers can control and monitor the ICCP system from one location eliminating the time and inconvenience of going from one end of the ship to the other”, Mr Rogers explained.

    The installation package for the tankers includes the provision of Cathelco seawater pipework anti-fouling systems.

    The Jiangzu New Shipyard is also building four 64,000 dwt bulk carriers for German owners Peter Dohle. These will installed with Cathelco forward and aft Quantum ICCP systems offering the same advantages of easier control and monitoring. The vessels will also be installed with seawater pipework anti-fouling systems.

    Last but not least, Nantong Tongshun has received an order to for two Anchor Handling Tug Supply (AHTS) vessels Pacific Crest with delivery scheduled for July and August 2015. Each of the vessels will have Cathelco seawater pipework systems installed in four seachests.

    “Sales in the China are beginning to return to 2008 levels, although the market is still very competitive. By developing products with innovative features such as the Quantum ICCP panels and combining this with first class support for the shipyards, Cathelco are winning a major share of this very important market”, concluded Peter Smith, sales director of Cathelco.
