Williams Partners LP announced Oct. 29 it expects its expanded Geismar Olefins plant to begin manufacturing ethylene for sale in November. That time line is consistent with the financial guidance the partnership provided in July.

All major construction related to the rebuild of the damaged plant, the expansion project and the safety-related equipment installation is now complete. The general contractors for the expansion and rebuild projects have demobilized, and Williams' operations personnel are now directing the dry-out and commissioning of the plant.

"We are in the final stages of commissioning and startup," said John Dearborn, senior vice president of NGL & Petchem Services, in a statement. "We fully expect to be manufacturing ethylene for sale in November, consistent with our financial guidance. We continue to place our highest focus on restoring safe and reliable operations for our employees, contractors, community and customers."

Capacity at the plant is now 1.95 billion pounds of ethylene per year.
