Welcome to [NDT Inspection Portal]’s cathodic protection group, a place for professionals to connect and discuss the latest techniques and technologies in cathodic protection.
Cathodic protection is a method used to prevent corrosion in metal structures, such as pipelines, tanks, and offshore platforms. It involves the application of a direct current to the metal structure, which creates an electrochemical reaction that slows or stops the corrosion process.
Cathodic protection is an important aspect of ensuring the integrity and reliability of metal structures in various industries, including oil and gas, water and wastewater, and transportation. It involves the use of specialized equipment and techniques, including voltage and current measurements, to monitor and control the cathodic protection process.
Our member group offers a platform for sharing knowledge and best practices on cathodic protection and its applications in various industries. Join our community of experts from around the world and be a part of the conversation on advancing the practice of cathodic protection and its applications in the field of NDT and inspection. Whether you are new to cathodic protection or an experienced professional, you’ll find valuable resources and a welcoming community in our group.

If the existing cathodic protection system is adequate, it should easily protect the portion of pipeline in the water as water is less resistive than soil. However, you might consider installing a permanent reference electrode in this location for occasional measurement.
I believe however that the biggest risk will likely be possible crevice corrosion at the tape to paint interface.
A very diligent visual inspection procedure should be established to insure the exterior of the pipeline remains corrosion free.
