Shielding of cathodic protection (CP) by disbonded coatings is considered a “worst case scenario” for external corrosion in the pipeline industry. It has been hypothesized that if coatings were partially permeable to CP, the imbalance between cathodic and anodic reactions would induce a high pH environment under disbonded coatings and that would impede corrosion. However, direct experimental evidence of this process has been limited. Moreover, this line of reasoning is often inversed incorrectly assuming that the only reason for the presence of a high pH environment under disbonded coatings is their partial permeability to CP current.

The recent development of an electrochemical self-validating technique to measure the relatively small ionic currents that could permeate through defect free coatings has shed a new light on the topic. It has been found that most of the commercial pipeline coatings tested in unaged conditions present a CP shielding behavior. Accelerated hydrothermal ageing of fusion-bonded epoxy (FBE) coatings was performed to study the effect of water absorption. Ageing resulted in major plasticization, which increased the conduction of CP current through FBE coatings. However, FBE seems to be partially permeable to H+ and/or OH-, which reduces its ability to form and retain a high pH environment under disbonded coatings. In conjunction, these results thus indicate the extremely limited capability of commercial pipeline coatings to prevent corrosion in case of disbondment.

Painting Practices for Floating, Storage and Offloading Systems

Product Number: 41211-655-SG

Author: Michael B. Surkein, Robert H Rogers, Sophia Woodley

Publication Date: 2011

Floating production storage offloading (FPSO) system hulls physically resemble ocean going transport vessels but operate more like fixed offshore structures. FPSOs normally are moored in deep water and are connected to unique riser systems. As these production systems are typically designed for long life, 20 to 30 years, corrosion control of the hull is extremely critical to help assure the required performance is obtained.

Performance of Distributed Galvanic Anode Systems in Bridge Structures

Corrosion of reinforcing steel is recognized as the major cause of the deterioration of reinforced concrete structures. Exposure to de-icing salts, seawater and chloride-containing set accelerators, plays a significant role in reinforcing steel corrosion (Figure 1). When the chloride content at the rebar level exceeds the threshold for initiation of corrosion, the passivation protective film on the rebar surface is destroyed and a corrosion cell can form either on the same piece of rebar with anodic and cathodic sites adjacent to each other, or a macro-cell between two different layers of reinforcement.

Potential Theory Applied to Cathodic Protection Design, 2nd Edition

Product Number: 37694-POD

Publication Date: 2024

NEW! The first edition of Potential Theory Applied to Cathodic Protection Design showcases the mathematical development of analytical equations for the design of cathodic protection (CP) systems for underground structures with anode groundbeds having various configurations. Equations include calculations for the resistance and voltage (potential) to assist the CP design engineer.

This second edition has several important changes including updates on integral and analytic solutions for horizontal anodes in the same trench, an approach that was insufficiently developed in the first edition.

Also new for the second edition is an index for enhanced reader experience.

Other updates include:

•Generalization of groundbed resistance combining the equation for anodes with different length and depth, with the equation for different distance between anodes.

•Calculation of anode’s current in a groundbed, based on the crowding factor.

•Generalization of groundbed resistance combining the equation for anodes with different length and depth, with the equation for different distance between anodes.

•Calculation of anode’s current in a groundbed, based on the crowding factor.

•By means of the use of integral formulations, particularizes the use of the APM for any combination of underground anode systems.
