Atlantic Sunrise pipeline project, US
Name of the Project
Atlantic Sunrise pipeline project.
Location
US.
Client
Transcontinental Gas Pipe Line Company (Transco), a subsidiary of Williams.
Project Description
The project aims to expand Transco’s existing pipeline system from the Marcellus shale production area, in northern Pennsylvania, to deliver an incremental 1.7-million dekatherms a day of year-round firm transportation capacity to its existing south-eastern market areas.
The proposed project includes about 317 km of pipeline comprising:
• about 300 km of new 76-cm- and 107-cm-diameter greenfield natural gas pipeline;
• a pipeline known as Central Penn Line (CPL) North and CPL South, in Pennsylvania;
• 19 km of new 91- and 107-cm-diameter looping pipeline, known as the Chapman and Unity loops, in Pennsylvania;
• 4 km of 76-cm-diameter replacements in Virginia; and
• associated equipment and facilities.
The project’s above-ground facilities will include:
• Two new compressor stations in Pennsylvania;
• additional compression and associated modifications to three existing compressor stations in Pennsylvania and Maryland;
• two new meter stations and three new regulator stations in Pennsylvania; and
• minor modifications at existing above-ground facilities at various locations in Pennsylvania, Virginia and North and South Carolina to allow for bidirectional flow, and the installation of supplemental odourisation, odour detection, and/or odour masking/deodorisation equipment.
Potential Job Creation
During peak construction periods, the project is expected to directly employ an estimated 2 300 people in ten Pennsylvania counties. In addition, the project could support an additional 6 000 jobs in related industries and generate up to $1.6-billion in economic activity, according to researchers at Pennsylvania State University.
Value
$3-billion.
Duration
The pipeline is scheduled to be put into full service in mid-2018.
Latest Developments
Williams Partners has announced that the US Court of Appeals for the District of Columbia has denied an emergency motion to stay the Federal Energy Regulatory Commission’s authorisation of the company’s Atlantic Sunrise pipeline project, allowing for construction to immediately resume.
Construction on the project started seven months ago after a nearly four-year, comprehensive federal and state regulatory review process.
Key Contracts and Suppliers
