The cofferdam will be built around the Battleship North Carolina, allowing the enclosed around the ship to be de-watered to create a dry work environment. Four water-tight weir gates are built into the structure allowing water to be pumped in and out of the work space. The cofferdam will allow for a dry work space for repair, without moving the ship.
However, unlike most cofferdams, which are temporary, this one will serve as a permanent structure around the Battleship- allowing for future repairs and maintenance.
