The Navy does do minor repairs at sea and pier-side at Naval Stations. The majority of the work pier side is a continuation of an availability that overran time. It's very common these days unfortunately.. When the ship comes into a commercial yard for availability it is stripped down of confidential equipment. All of the radar/sonar/fire control/damage control equipment comes off. The work done in the yard is primarily mechanical. Deck inserts, foundation repair, lube oil system, oily waste, etc. I will install the foundation for a SPQ-9b antenna, but I will never see the antenna. At the end of the availability the combat systems engineers from MARMC/SWRMC will come out, install the equipment, record all "installed" alignment information, and program the systems. The major new shipbuilders are rarely in the business of ship repair. They're too busy building new ships. General Dynamics is probably one of the few in the new build and repair business. When the ships come into a commercial shipyard the work items are all specced out by the planning yard. That's typically Huntington Ingalls in Mississippi or Bath Ironworks. The days of foreign shipyards is all but over as far as I know. They brought the USS Cole all the way back to the USA on the Blue Marlin. In fact, she went to Pascagoula, but I don't know if it was to Huntington Ingalls or VT Halter. I'd imagine HI.
