en.Wedoany.com Reported - Sempra Infrastructure has completed the Port Arthur Pipeline, which will support the transport of 20 billion cubic feet per day (Bcfd) of U.S. natural gas to global markets, supplying the currently under-construction Port Arthur LNG Phase 1 project, which has a nameplate capacity of approximately 13 million tonnes per annum (mtpa).

Sempra Infrastructure completes Port Arthur Pipeline

The company stated that the pipeline connects to Sempra Infrastructure's Gillis Hub Pipeline, a highly interconnected natural gas pipeline gathering system in the energy corridor of southwestern Louisiana. The pipeline also connects to Sempra Infrastructure's LA Storage facility, which is under construction, facilitating the transport of natural gas to and from storage facilities along the Gulf Coast.

The capital expenditure for the Port Arthur Pipeline Louisiana Connector is less than $1 billion, and the project includes a 72-mile (116-kilometer) long, 42-inch diameter pipeline, a compressor station in Beauregard Parish, Louisiana, and related above-ground and underground facilities.

Justin Bird, CEO of Sempra Infrastructure, stated that through rigorous execution, the project was delivered ahead of schedule and under budget, demonstrating what the team can achieve around the shared mission of becoming the leading energy infrastructure company in North America.

In March 2023, Sempra Infrastructure (Sempra is reducing its stake to 25%) made a final investment decision on Phase 1 of its approximately $13 billion Port Arthur LNG export project. Bechtel won a $10.5 billion EPC contract, including the construction of two production trains with a total capacity of approximately 13 mtpa and two storage tanks with a capacity of 160,000 cubic meters each. The expected commercial operation dates for Train 1 and Train 2 are 2027 and 2028, respectively.

Additionally, Sempra Infrastructure made a final investment decision on Phase 2 of the Port Arthur LNG project last year. Including the 13 mtpa capacity from Phase 1, the facility's total capacity will reach approximately 26 mtpa. The expected commercial operation dates for Train 3 and Train 4 are 2030 and 2031, respectively.
