The Tangier Med Port is a strategic investment by the government of Morocco which has been built to serve the country for the next 100 years.  An impressed current cathodic protection system has been installed to prevent the corrosion of the reinforced concrete caissons supporting the nearly 3km long jetty at the heart of the new port.

CPCL was selected to provide the cathodic protection materials for the caissons, including embedded anodes, reference electrodes and cables. 28 multi-channel, oil cooled, transformer rectifiers were manufactured to a rigorous client specification featuring nearly 1,000 separate DC outputs and monitoring/control using over 2,000 reference electrode inputs.  These TR units were equipped with full remote control and monitoring capability.  The large scale and complexity of the project presented a number of unique challenges affecting both the design and manufacture of these units which were successfully overcome.  Many innovations were necessary to ensure that the client’s expectations in terms of reliability, cost and performance were achieved.

This was the largest Transformer Rectifier project ever undertaken by the company.  It was completed on time and on budget and we believe that it is the largest thyristor transformer rectifier installation in the world.

Ras Laffan, Qatar


Lying 50 miles north of the capital Doha, Ras Laffan is Qatar’s main site for the production of liquefied natural gas and gas to liquid.  Client Qatar Petroleum commissioned CPCL back in 2007 for what has become the company’s largest ongoing project to date.

The contract has involved the design, supply and commissioning of cathodic protection systems for a new reinforced concrete substation building, as well as metallic water tanks.  As the contract progressed, the company was commissioned to also supply CP systems for piles, decks, capping beams and walkways for container and tug berths as well as naval base structures.

To date the project has been worth close to £3.5 million.
