DESIGN CONSIDERATION AND INTERFACING BETWEEN ONSHORE TO OFFSHORE PIPELINE CATHODIC PROTECTION SYSTEMS

摘要

The design of cathodic protection systems for offshore pipelines generally follows design parameters from DNV, ISO or in many cases in-house standards prepared by the pipeline owners/owners. Onshore pipelines follow very different and less defined standards and parameters. The interfacing between the onshore and offshore pipeline can therefore lead to a number of challenges and conflicting requirements. This paper is aimed at highlighting the potential issues, the design approaches which can be considered, and the factors affecting the final design.
