Modular Anode Sled Development and Testing for Cathodic Protection of Immersed Steel Structures

Project ID: 22060
Principal Investigator: Matthew Jermyn
Research Topic: Improved Power Generation
Funded Fiscal Years: 2022, 2023 and 2024
Keywords: None

Research Question

How does the use of an anode sled to apply CP to Reclamation infrastructure compare to traditional approaches?
• What cable protection/redundancy is needed to achieve 20 year service life?
• How do anode-to-anode interactions affect current output and anode consumption?
• Can anodes be configured on a sled in such a way to minimize anode-to-anode interference?
-Performance calculations, as found in von Baeckmann's "Handbook of Cathodic Corrosion Protection" will be used to benchmark performance of a closely installed CP system. Current literature on the theoretical performance of anode arrays will be used to estimate performance for design of the anode sled CP system.

-For empirical determination of performance, several anode sled configurations will be designed for and installed on the fish screens and trash racks at Marble Bluff Dam and Pyramid Lake Fishway. With the aid of junction boxes routine CP inspection techniques can be utilized to track performance over the period of this study.

-Comparison of empirical results to theoretical calculations and the performance of traditional CP systems will be used to determine if the system performs adequately (equal or better than traditional systems). Use of multiple configurations will determine the optimal anode sled design out of those installed.

Need and Benefit

This research will demonstrate an alternative technique, the use of alternative anode sled anode sled designs, to improve corrosion protection for existing structures and equipment. A draft revision of this proposal was provided to the appropriate research coordinator and has received permission to proceed.
