- Abstract:
-
This GIS data layer represents the Northeast Gateway Deepwater Port and Lateral, an approximately 16-mile long, 24-inch diameter natural gas pipeline lateral that interconnects with Algonquin's existing offshore Hubline natural gas pipeline system in Massachusetts Bay. The original survey for the bottom position of the pipeline was established by a combination of surface position of the installation vessel using DGPS, diver's surveys, multibeam surveys, and sidescan surveys. The project was surveyed in accordance with the USACOE's minimum standards and techniques as defined in the engineering manual EM 1110-2-1003. This file represents pipeline lateral layout as of 09/27/05, with an update on 06/30/2009 to include the subsea flowlines to the two natural gas receiving facilities that are part of the Northeast Gateway Deepwater Port.
- Purpose:
-
The data was developed in support of Algonquin's Application to the U.S. Maritime Administration and the U.S. Coast Guard for the Construction of the Northeast Gateway Deepwater Port, June 2005, and the Supplemental Environmental Report for the Northeast Gateway Deepwater Port and Pipeline Lateral, October 2005. The data is subject to change as a result possible issues remaining in the local, state and federal regulatory permit approval process, and minor changes typical between permit plans and as-built conditions.
