Massachusetts Bay 30-inch Pipeline

HubLine Pipeline

The HubLine Pipeline Project is a 30-inch diameter offshore pipeline approximately 29 miles in length constructed in the environmentally sensitive waters of Massachusetts Bay. The pipeline extends from Beverly, Massachusetts to Weymouth, Massachusetts.

The installation of the HubLine Pipeline Project involved a variety of construction techniques and methodologies never before performed in this area of the Atlantic Ocean. These included Horizontal Directional Drilling (land-to-water and water-to-water drills predominantly through bedrock to protect sensitive near-shore areas), shallow water construction utilizing spud moored vessels, and offshore construction utilizing anchor moored vessels. Burial of the pipeline was also accomplished by multiple construction techniques including bucket dredging, rock blasting, plowing, jetting, backfill plowing, and rock and sand cover placement.
