This presentation was made by Ken Lax, Technical Director of Corroconsult, on behalf of the Pipeline Industries Guild (PIG) Onshore Panel as part of their ongoing free webinar series.

The presentation is aimed as a non-tenchnical introduction to this rapidly growing phenomenon, within the field of corrosion, as the scale and number of photovoltaic (PV) systems, i.e. solar farms, increase worldwide.

No electrical or electrochemical knoweledge is assumed.

An overview of the following is given;

• External corrosion on buried pipelines

• Cathodic protection and coatings

• Effects of stray current on external corrosion

• Photovoltaic (PV) system construction components

• Sources of electrical interference from PV systems

• Prevention of stray currents from PV systems

• Mitigation of adverse effects on buried pipelines

The scope of the presentation covers the follwoing three possibilities;

• New PV System with Existing Pipeline

• Existing PV System with Existing Pipeline

• Existing PV System with New Pipeline

All slides prepared by Ken Lax and Richard Lindley (Projects Director at Corroconsult UK Limited) with additional content provided by Professor C. Charalambous (Univeristy of Cyprus) and Dr Thomas Löffler (Dekotec).
