The control panel supplies an impressed current which provides the driving force ‘potential’ which ensures protection of the whole subsurface structure. This protects nodes and extends beneath the mudline.

  • Proven robust design.
  • Low maintenance cost.
  • Control of corrosion by zones.
  • Compact size.
  • Local, hard wire or internet interfaces.

Thyristor control panels

As an alternative, Cathelco offer thyristor control panels, built to a well proven design. Adjustments can be made to finely balance the system to achieve the best spread of potentials across all of the anodes. As with the modular design, the system can be controlled directly from the panel or land based central control room. In addition, the performance of the system can be monitored remotely over the internet using a personal computer.
