Great Lakes Shipyard Launches Tug Wisconsin propulsion system includes the Logan

FlexaDrive Hybrid power system, allow- ing the tug to operate on electric power while at idle, underway at low speeds or when under low loads, without the need to utilize the main engines, reducing emis- sions and the cost of engine maintenance.

The tugs Cleveland, Ohio, Michigan and Pennsylvania were the ?rst new tugs built in the series as part of the Towing

Company’s ?eet renewal program.
