Abstract

This research seeks to reduce corrosion using cathodic protection with anode separation for the pipeline structures in Nembe Creek Flow Station. . Sacrificial anode and impressed current cathodic protection current demands of offshore X42 steel pipeline with 1.5m diameter and 100km length, and the onshore X65 steel pipeline with 1.0m diameter and 80km length, located in Niger Delta region spanning from Delta to Bayelsa State in Nigeria was determined using the data of the design parameters for the pipeline, anode and environment collected from NNPC/PPMC and by employing relevant Sacrificial Anode Cathodic Protection and Impressed Current Cathodic Protection methods respectively 4147440mA was estimated as 8381 anodes while 4839 anodes separated at a distance of 16.5m proportionally along the entire onshore pipeline length, are required to meet 35 years intended design life of the onshore pipeline
