REPAIRS & MAINTENANCE
Based in the former Philadelphia Naval Shipyard, our 118-acre facility is situated at the confluence of the Delaware and Schuylkill Rivers. We are conveniently positioned between Philadelphia International Airport and PhilaPort (The Port of Philadelphia). Our location in the Mid-Atlantic gives us great accessibility to the Atlantic Ocean and Gulf of Mexico. Aside from new build projects, Philly Shipyard offers services and capabilities for maintenance, repair, overhaul, and conversion (MROC) jobs.
