Title:
Algonquin Hubline natural gas pipeline, Massachusetts Bay, Massachusetts
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
This GIS layer shows the Hubline, an approximately 29.5 mile natural gas pipeline constructed primarily in the ocean along the coast of Massachusetts between Beverly and Weymouth. The route travels in a southerly direction through the communities of Salem, Beverly, Marblehead, Swampscott, Lynn, Nahant, Winthrop, Boston, Hull, Quincy, and Weymouth. This dataset represents an as-built location of the pipeline. 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.
Purpose:
The data were developed to support the requirements of both the Federal Energy Regulatory Commission and the U.S. Coast Guard, that a post construction survey be completed. Component of Massachusetts Office of Coastal Zone Management Human Uses database.
