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).
