Boston Harbor Shipyard Launches New Dock Barges for MBTA
On January 29, 2026, Boston Harbor Shipyard & Marina (BHSM) in East Boston successfully completed a significant roll-on operation using its 500-ton floating drydock, *Providence*. This operation involved the launch of two newly fabricated dock barges, which are set to serve the Massachusetts Bay Transportation Authority (MBTA) ferry terminal in Hingham. The 115-foot by 30-foot barges, each weighing 120 tons, were constructed by Blue Atlantic Fabricators, a tenant of BHSM and an AISC-certified facility. The project was awarded to Blue Atlantic in February 2025, with the first two barges delivered in November of the same year. A third barge is currently under construction.
The new dock barges are anticipated to enhance the rider experience at the Hingham ferry terminal. Michael Julian, general manager of Blue Atlantic Fabricators, emphasized that the new docks will also ensure compliance with updated accessibility standards. This initiative is part of a broader effort to improve transportation infrastructure in the region.
Innovative Launch Process Utilizes Advanced Technology
The launch of the dock barges involved a carefully coordinated transfer process. The barges were rolled directly from Blue Atlantic’s fabrication shop onto the *Providence* using self-propelled modular transporters (SPMTs) provided by Bay Crane Northeast, based in Wilmington, Massachusetts. To facilitate this operation, the drydock deck was matted to create a secure runway, with additional support from ACK Marine, another BHSM tenant.
Myles Murphy, drydock manager at BHSM, noted the advantages of the drydock’s design, stating, “The fact that the dry dock can sink to over 12 feet allowed us to be able to block the barge high enough for the SPMTs to safely egress from the pontoon deck with room to spare.” This capability was crucial for the successful transfer of the barges.
Engineering and planning support for the operation was provided by A. Waller Associates and JMS Naval Architects. These firms developed the dock loading arrangement, ballast plan, and sequencing necessary for the operation. Murphy highlighted the collaborative effort, stating, “This is a great example of what can be achieved when shipbuilders, heavy-lift specialists, naval architects, and shipyard operators work as one team.”
The *Providence* drydock, installed in May 2025, measures 120 feet by 60 feet and features eight ballast tanks equipped with remotely operated pumps and flood gate valves. The system is fully computer-controlled from a central control station, ensuring precise management of the drydock’s operations. Additionally, 12 LevelCOM sensors monitor tank levels and draft at all four corners, allowing for accurate leveling during operations. The drydock is also outfitted with 10 sliding side-bilge blocks, which can be adjusted to support various hull configurations, enhancing its versatility for future projects.
