The tugboat Powhatan, operated by Donjon Marine
, Co., Inc., leads Donjon's 1,000-ton-capacity derrick barge the Chesapeake, the largest floating crane on the East coast, and two laden Lockwood Marine tug/barge units southbound in the ice-laden Hudson River from
the Port of Albany in late January. The Donjon tugboat, Mary Alice, provides escort and added ice breaking capacity for the flotilla. The flotilla had just completed loading of General Electric manufactured turbines, generators and rotors onto barges for the domestic market. The 250-mile round trip on the Hudson was often through 20 inches of ice.
