CCSL renews cathodic protection on Tipner Interchange Bridge

Corrosion Control Services Limited (CCSL) has undertaken repairs to the existing cathodic protection monitoring system installed on M275 Tipner Interchange Bridge in Portsmouth.

Tipner Interchange comprises of two bridges, each with two reinforced concrete piers. Each pier consists of 10 concrete columns and two crosshead beams which an Impressed Current Cathodic Protection (ICCP) system is installed to each of the structures.

The contract, awarded by Colas, was to carry out initial testing of the system to confirm compliance with the standards. CCSL undertook testing with a portable power supply and showed that the ICCP system polarised and satisfied the performance monitoring criteria. The works also involved replacing the existing remote monitoring and control equipment and re-commissioning of the ICCP system installed to the structures.

CCSL engaged the services of remote monitoring specialists Omniflex to design and manufacture the new remote monitoring equipment.

The solution Omniflex provided, using their innovative web based PowerView ICCP System and incorporating their highly efficient PowertermT/Rs, can be operated and controlled by the client locally on an Easyview Touchscreen Interface or remotely via the web.

The PowerView ICCP system allows the client to access to the data and control of the system from any web enabled device. This also means the client no longer needs a dedicated PC and software license to monitor their ICCP system. As a result, management and control of M275 Tipner Interchange Bridge ICCP assets are now more economic, easier, quicker and more reliable.

The new monitoring system, which is the first use of Omniflex equipment for a reinforced concrete structure in the UK, was installed and successfully re-commissioned and will subsequently be monitored by CCSL for a period of 52 weeks.
