Hovensa Oil Refinery News

Rolls-Royce Commercial Marine has been contracted to upgrade Interlake Steamship Company’s Tug Dorothy Ann. The 124-foot, 7,200-horsepower Z-drive tug is the largest Z-drive ATB tug built to date in North America and is mated to the barge Pathfinder. The duo is engaged in hauling bulk commodities on the Great Lakes. The upgrade will convert the Dorothy Ann’s Rolls-Royce/Ulstien azimuth thrusters from fixed-pitch to controllable-pitch propellers. The project will include replacement of the lower drive units as well as all thruster control systems on the vessel.

At Great Lakes Shipyard, Cleveland, OH, the laying of the keel marks the start of construction on a 60-foot work boat for the Port of Milwaukee. The city of Milwaukee, Wisconsin awarded the contract in June 2011. The vessel is scheduled for completion by the end of this year. Designed by Jensen Maritime Consultants, Seattle, WA, the vessel’s capabilities will include general harbor work, icebreaking, salvage and dive operations. The stem and hull shape will be strengthened to optimize performance in ice.
