Williams Partners reports Atlantic Sunrise pipeline nears completion on East Coast

Tulsa’s Williams Partners L.P. reports its Atlantic Sunrise pipeline project is nearing completion.

The line is considered by the company to be a “critical expansion” of the existing Transco natural gas pipeline connecting Marcellus gas supplies with markets in the Mid-Atlantic and Southeastern U.S.

Williams indicated this week that the project is targeted for mechanical completion in August with full service anticipated to commence in the second half of the month. Full service will include transportation of 1.7 billion cubic feet a day of natural gas.

The company said that part of the mainline component of the project is already in service and moving about 550 million cubic feet per day of gas.

The mechanical completion date is based on the contractor schedules and could be affected by weather. The Greenfield construction on the Pennsylvania part of the line started in September 2017.

The project includes the installation of nearly 200 miles of large diameter pipeline, two greenfield compressor stations and compressor station modifications in five states. The segment known as the Central Penn Line will be jointly owned by Transco and a third party.

Approval for the project came in February 2017 from the Federal Energy Regulatory Commission.
