A major update of the 1992 NACE T7L192 Publication “Cathodic Protection Design
Considerations for Deep Water Structures” has been completed by Task Group TG 269 and the
updated document issued1. The report update addresses the significant changes regarding
cathodic protection (CP) 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 ~3,000
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.
