Cathodic Protection Survey for Whyalla to Port Bonython Gas Pipeline – Epic Energy

We conducted a detailed cathodic protection survey on behalf of our client, Epic Energy, for the Whyalla to Port Bonython gas pipeline. The focus of this project was to ensure the pipeline’s integrity and longevity by utilizing the Direct Current Voltage Gradient (DCVG) technique—a leading method for detecting coating defects and assessing the effectiveness of existing cathodic protection systems.

Project Objective

The main objective was to evaluate and identify areas along the pipeline where coating damage or defects may compromise its structural integrity. Through this DCVG survey, Epic Energy can ensure that their infrastructure meets safety and performance standards, minimizing the risks associated with corrosion.

Survey Methodology

Our team deployed the DCVG technique to measure voltage gradients in the soil above the pipeline. This method enabled us to:

Pinpoint Coating Defects: DCVG allows precise detection of even minor coating defects that may not be visible to the naked eye, which are critical to monitor for pipeline health.
Assess Corrosion Potential: By identifying areas with high voltage gradients, we provided Epic Energy with data on spots where corrosion potential is heightened, helping prioritize repairs.
Verify Cathodic Protection Efficiency: The survey also verified the effectiveness of the current cathodic protection system, ensuring that it adequately shields the pipeline from corrosion.

Outcomes and Client Benefits

The survey data provided Epic Energy with actionable insights into areas that required immediate attention. With our findings, they can implement targeted maintenance, thereby extending the pipeline’s service life and enhancing safety for the surrounding environment.

This DCVG survey for Epic Energy’s Whyalla to Port Bonython gas pipeline showcases our commitment to delivering precise, reliable, and proactive solutions for infrastructure protection and sustainability.
