Project Profile
Value: Undisclosed
Location: southeast portion of the Keathley Canyon protraction area, Gulf of Mexico, USA
Length (pipeline): 336-km
Capacity (pipeline): 400 MMcf/d of natural gas
Water Depth: 350 ft
The platform, located in approximately 350 feet of water, will be a four-pile structure with a two-level deck. It will be designed as an unmanned structure with a control system designed to shut down the facility in the event of an upset condition. The new infrastructure will enable the existing Discovery pipeline to operate at a higher pressure, both before and after the connection of the new Keathley Canyon pipeline. The 20-in., 209-mi (336-km) Keathley Canyon Connector, which is capable of gathering more than 400 MMcf/d of natural gas, originates in the southeast portion of the Keathley Canyon protraction area and terminates into Discovery’s 30-in. diameter mainline at Discovery’s new junction platform. The pipeline was constructed in depths of up to 7,200 ft (2,195 m) of water approximately 300 mi (483 km) south-southwest of New Orleans. The Keathley Canyon Connector extension is supported by long-term agreements with the Lucius and Hadrian South owners, as well as the Heidelberg and Hadrian North owners, for natural gas gathering, transportation and processing services for production from those fields. In addition, the new pipeline system is in proximity to other high-potential deepwater Gulf of Mexico discoveries and prospects. Williams Partners L.P. owns 60% of the Discovery system and operates it. DCP Midstream Partners, LP owns 40% of the system.
