Potential Measurements, How To Effectively Monitor The ‘Health’ Of Your Cathodic Protection System

Potential Measurements, How to Effectively Monitor the ‘Health’ of your Cathodic Protection System
Available for download

Potential measurements are often referred to as the ‘language’ of corrosion.  They are the most fundamental process in the field of corrosion control.  The purpose of potential measurements is to obtain a general idea of the ‘health’ of the cathodic protection system.

Structure-to-electrolyte potential measurements are the most fundamental process in the field of corrosion control.  The purpose of a potential measurement is to obtain a general idea of the ‘health’ of the cathodic protection system.  Potential measurements are often referred to as the ‘language’ of corrosion.

Some companies call it taking a read or measuring a key point, but in the end we are all performing the same type of testing.  Many of us perform this activity year after year without acknowledging all of the very import factors involved to complete the work effectively.  A well-maintained cathodic protection system requires reliable testing in order to verify its status.

Obtaining The Polarized Potential Under AC Interference

The -850 mV (CSE) criterion refers to the polarized pipeline potential that is free of any IR-drop. Different methods to obtain the polarized potential exist. Interruption of the CP current will cause the current, I, and thus the IR-drop to become zero and the remaining polarization immediately after the interruption is representative of the polarized potential of the pipeline.

There are several ways to validate the performance of a cathodic protection (CP) system for buried pipelines. Over the years, pipeline networks and their corrosion challenges have become increasingly complicated, not least due to the many sources of both AC and DC interference that affects CP operation. Also, the various measurement techniques that can be applied to test CP effectiveness has increased over the years. Finally, the sheer number of buried pipeline miles has been constantly increasing.

Oil and gas buried pipelines are protected against corrosion by both organic coatings, a passive protection system, and cathodic protection, an active protection system. When coating defects occur, CP controls the corrosion of the exposed steel surface. From an operating point of view, cathodic protection interruptions can occur on the network during interventions, consignments, or technical problems. Literature indicates that during CP interruption the corrosion rate of the metal remains lower than its free corrosion rate. Application of CP confers a remanence of protection to the metal. The objective of this study is to determine the safe duration for cathodic protection interruptions depending on environmental and cathodic protection conditions.
