Considerations Associated with the Selection of Electrochemical Protection Systems for Reinforced Concrete Structures

Impressed current cathodic protection (ICCP) for reinforced concrete structures has been installed on numerous bridges and wharves in Australia over the past 40 years. The exposure conditions at the majority of these bridges and wharves made them more susceptible to chloride-induced corrosion.


The ICCP systems in Australia are designed, installed and monitored in accordance with the global cathodic protection standards such as AMPP Standard SP 0290-2019, International Standard ISO 12696:2022, and Australian Standard AS 2832.5 – 2008 (R2018).

Electrochemical corrosion protection systems have been used in Australia for many years for the corrosion protection of concrete infrastructure assets in marine environments.
Impressed current cathodic protection (ICCP) can be highly effective for the corrosion protection of reinforced concrete structures, however, some of the potential shortcomings of these systems are their performance in high resistivity concrete, anode installation defects in tidal zones, premature failure of some system components and the requirements for ongoing monitoring.


For galvanic-based anode systems, most of the recent innovations have been associated with backfill materials and the development of systems that incorporate a temporary impressed current phase followed by permanent galvanic protection. While the long-term performance of some of the newly developed systems is still subject to ongoing assessment, the overall performance data from galvanic-based systems indicates that one of the potential shortcomings is the inability of these systems to deliver sufficient corrosion protection over time, especially in highly corrosive environments.


This paper presents guidelines related to the selection process of the corrosion protection system for concrete structures. These guidelines have been developed based on the author’s experience with the design, installation, and monitoring of various corrosion protection systems installed in Australia for the protection of marine infrastructure assets.

Assessing the corrosion degradation of aboveground tank bottom plates is a critical challenge for the industry. Internal inspections are a useful way of assessing the integrity of assets but might severely impact normal plant operation. In 2006, Chang et al. conducted a study on storage tank accidents and concluded that 74% of reported accidents occurred in petrochemical refineries, and 85% of them had caused fire and explosions.

Over the past two decades, bio-based fuel-grade ethanols (BFGEs), derived from a variety of agriculture feedstocks (e.g., corn, sugar cane, soybean oil, and sugar beet), are increasingly being used as a renewable energy source to reduce the dependence of fossil fuels for motor vehicle applications. One cost-effective and environmentally benign way to transport BFGEs is through steel transmission pipelines. However, cases of environmentally assisted cracking (EAC) in the transportation of BFGEs have been documented including some in pipelines.

This production asset located in the deep-water offshore Brazil, producing heavy oil in the range of 16 to 24 oAPI. Mudline caisson separators with electrical submersible pumps (ESPs) are used to process fluids from multiple wells and boost them to the receiving floating production, storage, and offloading (FPSO) vessel(1). There are significant flow-assurance and corrosion challenges in operating the asset. One of the challenges is the production fields have limited subsea umbilical, necessitate the use of
multifunctional products to maintain the field’s integrity and mitigate any flow assurance and scale issues.
