The first phase of construction is underway at EEW-AOS monopile manufacturing facility that will include a 110,100 sq-ft monopile welding plant, located at the Port of Paulsboro Marine Terminal in Gloucester County, New Jersey.

This offshore wind manufacturing facility will be the largest in the U.S. and will be able to build 400-foot long, 2,500-ton monopiles to supply the 1,100 MW Ocean Wind farm off the coast of southern New Jersey.

The Harman Group provided structural engineering for concrete foundation systems for Phase 1 of construction.

The 70-acre site requires a concrete mat foundation to support the manufacturing of monopiles, which are 40 ft in diameter and weigh the same amount as 1,572 average cars. With this weight upwards of 5.5 million pounds, it is an enormous load to be put on a foundation system. These mammoth monopiles must be made on the waterfront, for direct loading onto barges as roads are unable to support this kind of load.

To ensure the manufacturing facility does not settle excessively, 9,250 cubic yards of concrete must be poured to create a supportive foundation system.

“The Harman Group has substantial knowledge of constructing and designing mat foundations, especially on demanding sites, which allows us to take on this engineering feat,” said Jan Vacca, principal and VP of The Harman Group. “We are proud to be a part of the team that is building offshore wind and clean energy, making New Jersey a leader in this category.”

Once completed, the foundation system will support multiple buildings on this 70-acre site. The project construction is ongoing.
