Pacific Connector Gas Pipeline LP (PCGP) is seeking US Federal Energy Regulatory Commission (FERC) approval to construct and operate a new 229-mi. (368-km), 36-in. (914-mm) diameter natural gas transmission pipeline capable of transporting 1,200,000 dekatherms per day of natural gas from interconnections with two existing interstate natural gas pipelines (Ruby Pipeline LLC’s Ruby Pipeline and Gas Transmission Northwest LLC’s GTN Pipeline) near Malin, Oregon, to the proposed Jordan Cove Liquefied Natural Gas (LNG) export facility being developed by Jordan Cove Energy Project LP.

The proposed Pacific Connector Project is comprised of the pipeline; a new compressor station in Klamath County, Oregon, USA; three new meter station locations; five new pig launcher/receiver units; and new communications towers and equipment.

The Klamath Compressor Station is needed to meet contract pressure and flow requirements at the Jordan Cove Meter Station. PCGP will install 82,000 hp (61,172 kW) of turbine-driven centrifugal compression – three operating units totaling 61,500 hp (45,879 kW), plus one standby unit of 20,500 hp (15,293 kW).

The compression units will be installed in a new Class 1 Division 2 rated compressor building. The compressor building will include fuel gas conditioning, measuring, and regulation equipment. Related suction and discharge headers and piping will be installed between the pipeline and the compressor units. Other buildings inside the station include a new control room/ancillary equipment building and unit valve skid buildings. The ancillary equipment building will include an air compressor system, hot water boiler, and back-up generator. A high-pressure vent system with a silencer will be installed in order to allow the station to be blown down. Other facilities will include an inlet filter/separator, lube oil cooler, inlet air silencer/cleaner, exhaust system, and gas coolers.
