This twin-screw self-unloading bulk carrier was built in two sections. The forward cargo section was built by American Shipbuilding Co., Toledo, OH and was transferred to the Amship yard in Lorain, OH where it was mated up with the aft section. The thousand footer was launched May 8,1980 and was christened Edgar B. Speer on June 4, 1980 for the Great Lakes Fleet of the United States Steel Co., Duluth, MN. She is powered by two Pielstick V-18 cylinder 9630 horsepower diesel engines driving 2 controllable pitch propellers making her one of the most powerful vessels on the Great Lakes. Her rated service speed is 14.75 knots. She is equipped with a bow thruster. The Speer's 20 hatches feed 5 holds where she is capable of carrying 73,700 tons at her maximum mid-summer draft of 32 feet 1 inch. Her unusual self-unloading system consists of a stern mounted 52 foot transverse shuttle unloading boom designed specifically for shore hopper loading.
With the Edgar B. Speer entering service in 1980, seven smaller lakeboats were sent to the scrap yards. These were the Eugene J. Buffington, D. M. Clemson, Thomas F. Cole, Alva C. Dinkey, D. G. Kerr, Governor Miller, and the J. P. Morgan Jr. The Speer's first cargo consisted of 55,000 tons of taconite pellets from Two Harbors, MN to Gary, IN.
Her unique unloading system restricts the Speer's cargo to taconite pellets. The only two locations that can accept the Speer's unloading boom are located in Gary, IN and Conneaut, OH. Her fleet-mate Edwin H. Gott, also built with a similar self-unloader, was converted to a standard self-unloading system with a 280 foot stern-mounted discharge boom thus increasing her flexibility. This conversion may be in the Speer's future as well.
