Gap Analysis of CP Design for Subsea Pipelines

Offshore pipelines face challenging marine conditions, such as exposure to seawater that speeds up the corrosion rate. While corrosion cannot be entirely eradicated, there are methods available for its reduction. Cathodic protection (CP) has traditionally been utilized as a crucial strategy for corrosion control and is widely acknowledged as the most efficient way to protect subsea pipelines. This study explores the complexities involved in the CP design for offshore pipelines and examines variations and discrepancies in design principles across different international standards.
