About this file
This is a historical drawing attachment depicting the salt water tunnel systems and Building 72 infrastructure at Portsmouth Naval Shipyard in Kittery, Maine. The document references Yard Plate No. 12, which provides a general layout of salt water tunnels updated through the early 1980s, and includes multiple engineering references spanning from 1912 through 1944. The original salt water intake tunnel was constructed in 1912 per reference drawing 72-12-0140, subsequently converted to a discharge tunnel after a new intake tunnel was constructed from Berth 5 in the 1930s (per drawings 72-33-0311 and 72-33-0317). Building 72's salt water pump room, currently referred to as "Room S," was constructed over the original intake well location, with initial construction documented in 1933 (drawing 72-33-0699) and an easterly addition completed in 1944 (drawing 72-42-0992). Additional engineering references include drawing 72-18-0311 (dated 1918) depicting the new salt water intake tunnel and planned initial construction limits of Building 72, and drawing 72-18-0317 (dated 1918) providing the tunnel profile and construction details. This historical documentation serves as reference material for the P1112 B72 Resiliency Improvements project at Portsmouth Naval Shipyard.
