Cathodic Protection

Complete CP Solutions

BSI cathodic protection (CP) systems combine mitigation of corrosion on structures with enhanced capabilities for performance monitoring, data collection, and control. Real-time data is uploaded to BSI’s online dashboard to provide constant assurance of a structure’s protection.

AC Mitigation

AC interference on pipelines threatens personnel safety and pipeline integrity. Proximity of cathodically protected pipelines to alternating current (AC) high voltage transmission lines necessitates an AC mitigation system to prevent electric shock and safely ground the pipeline to protect against AC-induced corrosion.

BSI provides complete AC mitigation solutions. Our experienced team of engineers design and install AC mitigation systems after assessing each unique situation. Systems paired with BSI monitoring equipment and services ensure AC-induced corrosion risks are controlled.
