Ojibwa Submarine


Riggs Engineering was hired by the Elgin Military Museum to assist on the marine engineering components of the project that brought HMCS Ojibwa, a cold war submarine to Port Burwell, Ontario. Our tasks included ensuring that the harbour bottom was dredged to sufficient grades and the design of the shore transfer dock.
