Overview of NACE State of the Art Report T7L192 “Cathodic Protection Design Considerations for Deep Water Projects”

A major update of the 1992 NACE T7l92 Publication “Cathodic Protection Design Considerations for Deep Water Structures” has been completed by Task Group TG 269 and the updated document issued.  The report update addresses the significant changes regarding cathodic protection that have occurred in deep water projects since 1992 when the deepest structures were in ~700 meters water depth while projects of today are in ~3000 meters water depth. This state-of-the-art report provides a summary of the information currently available in the literature regarding CP in deep water and the variables in seawater chemistry that affect CP and CP design. This report addresses environmental effects on CP, results of tests and field experience in deep water, and the present state-of-the-art technology in deep water CP design.  An overview of the report's updates is provided.
