Cathodic Protection

Evaluation of Florida Bridge Pilings

Many bridges in coastal areas are supported by precast pilings that are either continuously or periodically exposed to harsh saltwater conditions, requiring cathodic protection. These researchers studied two decommissioned pilings from the Veterans Memorial Bridge in Florida.

PHMSA Plans to Modernize U.S. Gas Pipeline Safety Rules

PHMSA is proposing to clarify that cathodic protection rectifiers can be monitored remotely and to revise the requirements for assessing atmospheric corrosion on distribution service pipelines.

U.S. Navy Utilizing Remotely Operated Vehicles to Check for Corrosion

The ROVs measure metal thickness, paint thickness, and cathodic protection (CP) voltage—a corrosion prevention technique the Navy uses that charges the hull at a certain voltage to slow down corrosion.

Nomination Period Opens for 2021 MP Corrosion Innovation Awards

The nominating period is now open for next year’s Corrosion Innovation of the Year Awards, with winners recognized in a wide range of categories related to corrosion prevention and mitigation.

Applying Over-the-Line Potential Surveys in Water/Wastewater Pipelines

Researchers performed two case studies to determine if over-the-line potential surveys could be successfully applied to electrically discontinuous water/wastewater lines and if the results aligned with the direct assessment methods.

Corrosion Basics: Locating Pipeline Coating Defects with a Pearson Survey

One of the first successful techniques for locating coating defects (holidays) on buried pipelines using surface electrical measurements is the Pearson survey, named after its inventor.

Experienced concrete maintenance and restoration specialists explain the unique challenges in protecting parking structures from a constant onslaught of environmental stressors and wear and tear, along with examples of successful repair techniques.

Unmanned Aircraft Collect Cathodic Protection Readings on Remote Pipelines

Unmanned aerial vehicles (UAVs), are being utilized more and more in various industries to safely and efficiently inspect critical assets and infrastructure that would otherwise be difficult to access.

Internal Cathodic Protection Retrofit for Auxiliary Cooling Water Pipes

A combined-cycle power plant in Asia utilizes seawater as auxiliary cooling water (ACW). The carbon steel ACW pipe was lined with coal tar epoxy. After six months in operation, the ACW pipe started leaking due to internal corrosion. A retrofit impressed current cathodic protection (ICCP) system was installed.
