Sacrificial cathodic protection system was applied for protection of prestressed concrete cylinder pipe in the Great Man made River Project pipelines in Libya, where 100 mV Polarization\Decay criteria was used to evaluate the performance of the cathodic protection.
Section of 2.29 km of protected pipeline that was existing between two sections of long non protected pipeline was selected for testing. All of the applicable tests were executed on the selected section before and after installation of sacrificial zinc anode system. The purpose of this study is to assess the reliability and efficiency of sacrificial CP system in the relatively high soil resistivity which has high chloride content and low moisture.
