JDR would supply 196km of inter-array cables and 180km export cabling to the project, currently under consideration by Maryland's Public Service Commission (PSC).
"We are extremely proud to be selected by US Wind for the full cable package," said David Currie, CEO of JDR Cable Systems.
"This partnership will strengthen Maryland and Baltimore as a regional business hub and support additional job creation. We are thrilled to be part of this exciting Maryland project," Currie added.
US Wind, a subsidiary of Italian renewable energy firm Renexia, submitted its plans to the PSC in November.
The 187-turbine project is planned for a site 18km from Ocean City, on the Maryland coastline.
It is competing with a 120MW Deepwater Wind submission for a different project to receive Maryland's offshore renewable energy credit.
"We're interested in putting together a whole new offshore wind industry right here, in Maryland, and bringing JDR here is a big piece of that puzzle," said US Wind president Riccardo Toto.
