P-381 Multi-Mission Dry Dock #1, Portsmouth Naval Shipyard (PNSY), Kittery Maine

This project constructs a partitioned addition to dry dock #1 (DD1) within the superflood basin area. The addition will consist of two bays, labeled dry dock #1 North (DD1N) and dry dock #1 West (DD1W). The existing dry dock #1 will be renamed dry dock #1 East. Both DD1N and DD1W w ill be of sufficient size and depth to support the maintenance and overhaul of Virginia (VA) Class submarines, Blocks I-IV. New construction will include concrete floors, walls, and center wall separating DD1N and DD1W, new pump well systems, pump station building, portal crane rails, mooring hardware, mechanical and electrical utilities, utility tunnels, and all appurtenances required to ensure an operational dry dock. Modifications will be made to the existing basin closure wall and to Berths 1 and 11 to prevent undermining and support fully dewatered conditions. The existing DD1 pumpwell will be connected to the new pumpwell system and the interior modified.
