Foreword. Foreword . Since the late 1970’s, marine and offshore operators have increasingly applied various proactive maintenance techniques to prevent failures before they occur, detect the onset of failures, or discover failures before Corrosion Measurement Techniques - PowerPoint PPT Presentation.

Because corrosion occurs via electrochemical reactions, electrochemical techniques are ideal for the study of the corrosion processes. In electrochemical studies, a metal sample with a surface area of a few square centimeters is used to model the metal in a corroding system.Measurements can be taken at 50 feet, 100 foot or larger intervals. It does not need to be taken every 5 feet to be effective. Measurements can be taken over many types of cover including concrete, rocks, pavement, and water with no detrimental effect. It allows the operator a quick way to determine the overall pipeline coating condition.
