TULSA, Oklahoma -- The 30-in. (76-cm) mainline of the Discovery offshore gathering system has been repaired and is back in service following damage sustained during Hurricane Ike, according to Williams Partners.
The offshore gathering system moves natural gas from Gulf of Mexico fields to shore. It sustained the damage in September, when an 18-in (46-cm) lateral was severed from its connection to the mainline in 250 ft (76 m) of water. The system had not been accepting gas from producers since being shut-in prior to Hurricane Ike, the company says.
The mainline is now delivering 150 MMcf/d of production, which was its approximate volume prior to the hurricane.
The damaged 18-in. lateral remains offline while repairs are being made, shutting in approximately 30 MMcf/d of production. The lateral is expected to be repaired and placed back in service by mid-February.
Williams Partners owns 60% of the Discovery system, which includes an offshore natural gas gathering system, as well as the Larose natural gas processing plant and Paradis fractionation facility. Neither onshore facility was seriously damaged. Both have been processing gas from third party sources since September.
