The GREENSTONE II, a U.S. Department of Interior fuel barge, was hauled out at the Port Calcite facility in late May 2014 with MIW’s 440-ton Manitowoc 16000 crane. Schwartz Boiler of Cheboygan, MI performed the blasting, painting, and repair work. Upon completion of drydocking, repair work, and inspections by the U.S. Coast Guard, the barge was relaunched at Port Calcite in late June.

Built by Fraser Shipyards in 2004, the 70’ long, 65-ton GREENSTONE II is a double-skinned fuel barge commissioned by the U.S. National Park Service for operation in Isle Royale National Park.
