HPFF PIPE TYPE CABLE SYSTEM

MasTec Professional Services delivered a complete cathodic protection engineering program for parallel 13-mile long high-pressure fluid-filled feeders between two substations. Our work included system evaluation, design, permitting, installation, and commissioning, along with assessment of oil tanks, low-pressure supply piping, and adjacent high-pressure feeder lines.

Our team performed electrical isolation inspections, corrosion assessments, and wall-thickness measurements, and conducted field testing along the route to evaluate existing cathodic protection performance and identify external stray AC and DC electrical influences. Findings, recommendations, and an action plan were provided in a comprehensive report.

MPS then designed and permitted a new cathodic protection system—ground beds, rectifiers, cut-out boxes, and isolation devices—and commissioned the installation with close-interval and DCVG surveys to verify system effectiveness.
