Hubline Natural Gas Pipeline Route in Massachusetts Bay

Massachusetts Bay hosts the as-built location of the Hubline, a 29.5-mile natural gas pipeline constructed primarily offshore between Beverly and Weymouth. The dataset was created by SCIOPS, representing the pipeline's surveyed bottom position. The route traverses 11 coastal communities including Salem, Boston, and Quincy.

Use Cases

• Analyze pipeline proximity to coastal communities like Salem and Boston using the route geometry.
• Assess potential environmental risks by overlaying the pipeline's geospatial location with marine habitat maps.
• Plan new infrastructure projects by referencing the surveyed bottom position established via DGPS and multibeam surveys.
• Model pipeline exposure to coastal hazards using its documented path through Massachusetts Bay.

Strengths

• Precise route defined for a 29.5-mile pipeline.
• Location established using multiple survey methods: DGPS, diver surveys, multibeam, and sidescan surveys.
• Route passes through 11 specified coastal communities.

Limitations

• Unknown number of data points or vertices defining the route.
• No metadata on coordinate reference system or positional accuracy.
• Dataset represents a single 'as-built' snapshot with no temporal updates.
