Keystone provided project management, engineering, and design services at a greenfield and existing site in South Carolina for the installation of additional compressors. The project goal included increasing the overall pipeline capacity.

The brownfield compressor station expansion added new compressors to increase capacity from 150 MMSCFD to 300 MMSCFD. The scope of work included the installation of new separation vessels, coolers, and fuel gas coalescers. The greenfield site included installing a Solar Saturn turbine with centrifugal compressors for 175 MMSCFD with separation vessels, compression coolers, and fuel gas coalescers. Additionally, Keystone provided procurement, bidding, and permitting support services for this project.
