OES CO2 PIPELINE FEED PROJECT Design Basis Memorandum

Summary

The Illinois Storage Corridor CarbonSAFE Phase III project outlines the Front End Engineering & Design (FEED) for the OES CO2 Pipeline, a 7.8-mile system to transport 4.5 MMTPA of CO2 from 2 sources to 3 injection sites in Illinois. The pipeline will operate at a maximum pressure of 2,500 psig and is designed with a 0.72 factor for mainline pipe. Key specifications include 16-inch OD X-60 steel pipe with 0.500-inch wall thickness, FBE coating (14-16 mils) with ARO (30-40 mils) for bores, and a minimum depth of cover of 6 feet (25 feet for HDDs). All field welds will be 100% inspected, and below-ground piping will undergo hydrostatic testing for at least 8 hours at 1.25 times the design pressure.
