Portsmouth Navy Yard, Modular Submarine Enclosure

Portsmouth, NH



The Portsmouth Naval Shipyard owns and maintains a temporary steel modular-enclosure system to protect submarines during overhaul, repair, and modernization operations. While a contractor was repairing the modules in a nearby staging area, strong winds knocked over two wall stacks, damaging and distorting a stair stack and five wall modules. The contractor engaged SGH to assess the damage and design repairs to restore the damaged modules to their original condition.
