Home / Cathodic protection

Cathodic protection for pipelines, wells and tanks.

Buried and submerged steel in southern Iraq faces saline, high-chloride soils. We supply and install complete cathodic protection systems built by UK and European manufacturers, and commission them to the operator's protection criteria.

Services

From survey to commissioning

Design is carried out with qualified CP engineers from our UK manufacturing partners. Our Basra crews install, test and hand over.

  1. Survey

    Soil resistivity, existing potentials and current requirement tests.

  2. Design

    Groundbed and rectifier sizing to the operator's specification.

  3. Supply

    UK and European equipment, documented and delivered to site.

  4. Install

    Groundbed drilling, cable laying, connections and test stations.

  5. Commission

    On and instant-off potential surveys and a full commissioning report.

Standards

Built and tested to recognised standards

We work to the standard the operator names. Typical references for Iraqi pipeline and facility work are listed here. The usual protection criterion for buried steel is an instant-off potential of −850 mV or more negative against a copper/copper sulphate reference electrode.
