Experimental Investigation of Effectiveness of FRP Composite Repair System on Offshore Pipelines Subjected to Pitting Corrosion Under Axial Compressive Load

Abstract The application of FRP composite is quite well demonstrated in strengthening on RC structures but steel still being investigated by many researchers. aggressive marine environment can cause corrosion to the offshore pipelines which would affect structural performance such as pitting could be considered most destructive was simulated this research. This study had attempted carry out experimental investigation effectiveness repair system subjected under axial compressive load. 3 groups specimens have been categorized intact, corroded and repaired. Results peak load, failure modes load–displacement behavior were concerned study. has proved that it significant effect ultimate strength pipelines. Number CFRP layer layers results showed capable However, more detailed studies are required conducted future consideration internal pressure order expand understanding system.
