A new maritime transport barge arrives at Electric Boat’s


On Monday, the new Holland sea transport barge arrived at Electric Boat’s Groton shipyard. The barge was specifically designed to support the delivery of Columbia-class guided missile submarines. General Dynamics Electric Boat is the prime contractor for the construction of the Columbia class.

The Holland was designed by Bristol Harbor Group, Inc. (BHGI) and built by Bollinger Shipyards, LLC, of ​​Lockport, La. The namesake of the new barge is John Holland, the Irish-born immigrant who designed the first submarine purchased by the US Navy. Holland’s design was designed by the Electric Boat shipbuilders and delivered in 1900.

BHGI started working with electric boat engineers in 2017 to design the one-of-a-kind vessel, and Bollinger was selected to build the 400ft by 100ft barge in November 2019. The concept and contract design was made by the Port of Bristol. Group in Rhode Island, while Bollinger performed detailed design engineering at its plant in Lockport, Louisiana, and construction at Bollinger’s marine manufacturing facility in Amelia, Louisiana.

“We are pleased to welcome Holland to his new home at the Groton Shipyard,” said Kevin Graney, President of General Dynamics Electric Boat. “Our fellow shipbuilders at Bollinger delivered a tremendous asset, on time and on budget. Holland will play an important role in building the Columbia class of submarines, which will carry nearly 70% of the country’s nuclear arsenal.

Bristol Harbor Group is proud to be part of the team that designed and built this unique vessel that will play a pivotal role in building the next generation of American ballistic missile submarines. Solving many unique design challenges involved demonstrates the world-class capabilities of our naval architects and naval engineers. ” said Daniel Eling, PE, BHGI Senior Naval Architect.

“Bollinger is proud to partner with General Dynamics-Electric Boat to support the United States Navy and one of our nation’s top strategic priorities,” said Bollinger President and CEO Ben Bordelon. “Being able to deliver OTB Holland on time and on budget is a testament to the strength, commitment and resilience of the men and women of Bollinger’s workforce, particularly as a result of significant damage to our shipyards and communities as a result of Hurricane Ida earlier this year. Bollinger looks forward to continuing to help meet the growing needs of the U.S. Navy and to support efforts to modernize our nation’s fleet. “

The Columbia class is now under construction at the Quonset Point Manufacturing Plant in Electric Boat, RI. Skilled workers will build and equip the Columbia modules at Quonset Point, which will then be transported by the Holland barge to the company’s final test and assembly facility in Groton. The first Columbia module is expected to arrive in Groton in 2023.

Construction of the Columbia-class, which will replace Ohio’s aging class, is the country’s top strategic defense priority. For almost 15 years, Electric Boat has been working on plans to execute the design and build of this crucial program. As a result, the Columbia class was the most complete design of any previous submarine class when construction began in October 2020. The company hired and trained thousands of new skilled workers, worked with its suppliers to prepare for the increased demand for technical services. and invested nearly $ 2 billion in new facilities to support the construction of the Columbia class.
