Corridor Management

Typical Applications

Any utility and transportation corridor carrying a mix of electrical transmission lines, pipelines, communication systems, roads and railways, all in close proximity to each other
Corridor management who need to ensure that the different corridor participants "play well" together so that one party in the corridor doesn't disrupt other participants
AC mitigation systems to reduce induced voltages in pipelines and other metal infrastructure
Lightning protection grounding systems to reduce the impact of lightning strikes on adjacent infrastructure and facilities and improve worker safety in the corridor
Grounding systems to protect control, monitoring and transportation signaling systems from noise and extraneous electrical signals produced by adjacent corridor infrastructure
Railway signaling systems
Highway monitoring and information advisory systems
Corrosion protection systems
Ground Potential Rise (GPR) safety studies required by telecom companies for sites located at or near high voltage utility infrastructure subject to ground faults, including soil testing and ground resistance calculations

Risks and Opportunities

Flashover from electrical or telecom towers in the corridor to adjacent pipelines due to insufficient lightning protection and other grounding systems, causing pipeline perforation and environmental contamination
Personnel safety compromised by high induced voltages due to insufficient grounding and AC mitigation systems
Corrosion of pipelines and other metal infrastructure due to galvanic and other electromagnetic activity, lack of AC mitigation or to insufficient or aged cathodic protection systems
Need to meet strict environmental regulatory guidelines for groundwater aquifer and soil contamination within the corridor
Potential failure and corresponding downtime due to the induced electrical noise or disruption of improperly grounded electronic control, monitoring and signaling systems in adjacent infrastructure
Need for Ground Potential Rise (GPR) safety studies by corridor participants locating near electrical transmission lines

Potential Solutions

Install or upgrade electrical and telecommunications tower grounding with robust, long-life and low maintenance SAE engineered grounding systems better suited to dissipating lightning energy without collateral effects to adjacent infrastructure
Install or upgrade pipeline AC mitigation systems with advanced materials that extend service life and reduce operational and maintenance costs for corridor users
Upgrade deep anode bed cathodic protection systems with the advanced technology, environmentally compliant EnvirAnode from SAE, an extremely long life, operationally efficient and 21st Century solution for this critical area
Provide grounding audits or GPR studies to meet technical and safety requirements

Next Steps

Review our products and capabilities in the context of your corridor requirements, whether technical, operational or environmental. Then call or eMail SAE inc. along with your corridor partners and users to discuss how we can manage the inevitable headaches when different infrastructures interact with natural phenomenon and with each other.
