Foreword

This state-of-the-art report provides owners, engineers, contractors, and operators with information on electrical isolation/continuity issues and coating issues to consider when designing and operating offshore pipeline cathodic protection (CP) systems. The detailed specifications for application of pipeline coatings are beyond the scope of this report, though it gives references to some specifications that are used. This report is a support document for the pipeline CP design standards.

This technical committee report was prepared by Task Group (TG) 169 on Control of External Corrosion of Steel Pipelines in Natural Waters. TG 169 is administered by Specific Technology Group (STG) 30 on Oil and Gas Production-Cathodic Protection, and sponsored by STG 05 on Cathodic/Anodic Protection and STG 35 on Pipelines, Tanks, and Well Casings. This report is issued by NACE International under the auspices of STG 30.
