With required federal and state permits in place, construction on the nearly $3 billion Atlantic Sunrise project began in September 2017 and is expected to last approximately 10 months. The project is scheduled to be placed into full service in mid-2018. Follow along to find out the latest on construction.
Williams has worked closely with permitting agencies to minimize environmental and stakeholder impacts, making modifications to more than half of the original pipeline route. In addition, Williams has worked with local stakeholders to provide an additional $2.5 million for conservation projects located within the project area.
Pipeline and compressor station construction is anticipated to last approximately 10 months, weather permitting. The nearly $3 billion project, which is designed to increase natural gas deliveries by 1.7 billion cubic feet per day, is scheduled to be placed into full service in mid-2018. Here is what you can expect to happen over the next few weeks:
Crews began staking out the rights of way (ROWs) Aug. 14. It’s important that the construction right of way is clearly identified, and staking allows that to happen. Stakes are used to mark the construction corridor, as well as environmental features, such as wetlands.
CLEARING AND GRADING
and other designated areas and stockpile it as part of reclamation. The ROWs will then be leveled and graded so contractors have a safe space in which to work. Part of grading involves the installation of erosion and sediment control devices along stream banks and wetlands so disturbed soil doesn’t erode and water sources are protected.
TRENCHING AND STRINGING
Upon completion of clearing and grading, excavators will dig the trench and place the excavated soil to the side. In agricultural areas, topsoil is removed from the work area and stockpiled to ensure it is not mixed with subsoil. Stringing is when pipes are transported from storage areas and laid out end to end along the ROWs so that they are easily accessible for construction personnel to bend, weld and lower into the trench.
BENDING AND WELDING
A pipe-bending machine bends the joints of the pipes to t the terrain and account for directional changes. After the pipes have been bent, contractors weld them together to ensure a proper, uninterrupted ow of natural gas. All welds are X-rayed
Before the trench digging starts, the ROWs must be cleared of trees and vegetation. When the area is cleared, contractors will remove the and coated. The entire pipe coating topsoil in agricultural, residential is then electronically inspected
