TG169 “Cathodic Protection in Seawater” technical committee has two assignments, to review the application and potential changes to ISO 15589-2 Petroleum and Natural Gas Industries—Cathodic Protection of Pipeline Transportation Systems and to write a committee report on offshore pipeline CP: electrical isolation/continuity and coating issues. Two new NACE documents have been issued in the last year under TG169 to meet these assignments. A modified adoption of “ISO 15589-2 Cathodic protection of pipeline transportation systems - Part 2: Offshore Pipelines”, was issued, making this a NACE standard. For items than were not included in ISO standard, but were still thought to be important, a NACE technical committee report was produced entitled “Electrical Isolation/Continuity and Coating Issues for Offshore Pipeline Cathodic Protection Systems”. This paper will give an explanation of the key issues of these two documents. Ian Rippon is the current chairman of TG169, and this paper represents the work done on that committee.
