Shipyard Infrastructure and Optimization Program Multi-Mission Dry Dock

The Multi-Mission Dry Dock (M2D2) constructs a reinforced concrete pressure relieved multi-mission dry dock with caisson to support the USS FORD (CVN-78) class and USS NIMITZ (CVN-68) class nuclear aircraft carriers, as well as all fleet nuclear submarine classes. Construction utilizes upland groundwater cutoff walls and cofferdam systems and includes bulkheads, quay walls, stairs, enclosed utility galleries, electrical and mechanical utility tunnels, drainage tunnels, discharge tunnels and saltwater system intake(s), closed loop cooling system, flooding and dewatering systems, passenger and freight elevators, vessel mooring hardware, bollards, capstans, perimeter safety railing, temporary services support hangers and area lighting. Work also includes fire protection, information technology, automated control systems compatible with the Shipyard and Naval Base Kitsap (NBK) Supervisory Control and Data Acquisition System (SCADA), dry dock process water collection system, and the process water/oily waste treatment system. Additionally, construction will include 40-foot gauge portal crane tracks, sanitary sewer, mechanical and electrical utilities, saltwater and freshwater fire protection, information and communications systems, and lighting. Procurement of equipment including a ship-style floating caisson gate and electrified 40-foot gauge portal cranes may also be included. Jessica Allen Alternative
