Chesterfield’s Cathelco wins orders for cruise ship corrosion protection


Chesterfield-based Cathelco have won orders to supply corrosion protection equipment for a number of cruise and commercial vessels being built in European and Far East shipyards.

Impressed current cathodic protection systems will be supplied for five cruise vessels being built by Fincantieri in Italy.

One of the systems will be installed on the latest Princess Cruise vessel, under construction for the Chinese market with the capacity to accommodate 3,600 guests. The 143,000-tonne ship, scheduled for delivery in 2019, will be identical to the Royal PrincessRegal Princess and Majestic Princess.

The Cathelco ICCP system, consisting of an arrangement of hull-mounted anodes and reference electrodes wired to a thyristor control panel, will protect the wetted surface of the hull against corrosion. In operation, the reference electrodes measure the electrical potential at the hull/seawater ‘interface’ and send a signal to the control panel which automatically raises or lowers the output to the anodes. In this way, the hull receives the optimum level of corrosion protection at all times.

Cathelco are also supplying ICCP systems for two 135,500 grt cruise ships which Fincantieri are building for Costa Asia and P&O Cruises Australia.  The hulls of both vessels will be protected against corrosion with 200 amp forward systems and 400 amp stern systems.

Viking Ocean Cruises already have Cathelco ICCP systems installed on six of their latest ships ordered from Fincantieri. They have now ordered a further two vessels from the Italian builder which will be installed with ICCP equipment. The sister ships, scheduled for delivery in 2021 and 2022 will be of the same design as the current vessels with the capacity to accommodate 930 guests in 465 cabins.

In the commercial sector, Cathelco are supplying two types of systems for six 82,000 dwt bulk carriers which are to be built for Oldendorff Carriers by the Hantong Heavy Industries shipyard in China.

Each of the vessels will be installed with marine growth prevention systems to protect seawater pipework against biofouling and ICCP systems to safeguard the hulls against corrosion.

The MGPS systems consist of copper and aluminium anodes which are fitted in the seachests and wired to a control panel. In operation the copper anodes produce ions which flow through the pipework system and create an environment where the larvae of barnacles and mussels do not settle or grow. At the same time, ions from the aluminium anodes create an anti-corrosive layer on the internal surfaces of pipes.

Cathelco MGPS and ICCP systems will also be installed on four 38,800 dwt chemical tankers which are being built by HHI for Carl Buttner of Bremen for delivery between July 2018 and September 2019

Meanwhile, Brittany Ferries’ newest cruise ferry is to be built at the Flensburger yard in Germany. The vessel, named Honfleur, will be installed with a Cathelco ICCP system to protect the hull against corrosion. It will operate on the company’s busiest route from Portsmouth to Caen and is planned to enter service in spring 2019.
