[1] Stephens-Adamson designed a loop belt elevator system, that feeds a stern mounted 260-foot (79 m) discharge boom that can be swung 100 degrees to port or starboard.

De Lancey departed Lorain on her maiden voyage on May 10, 1981, sailing in ballast to Silver Bay, Minnesota, to load 55,944 long tons (56,842 t) of iron ore pellets.

Loading 43,000 net tons in Conneaut, Ohio, both United States and Canadian Coast Guard services provided ice breaking assistance so that the voyage was completed without any delays.

That program recounts how in 2008, while leaving Sturgeon Bay, Wisconsin, MV Paul R. Tregurtha got stuck in ice and cracked steel plating on the port side of her bow, causing ballast tank water to leak out.

[2] At around 3 a.m. on August 15, 2012, as she was proceeding downbound with 62,000 tons of coal, the bow of MV Paul R. Tregurtha grounded in the outbound channel of St. Marys River, just north of the Neebish Island ferry crossing, near Sault Ste.

Her stern then pivoted and grounded on the opposite side of the channel, completely blocking the approach to the Rock Cut in the Lower St. Marys River.

This enabled salvage experts to successfully raise the ship's bow by filling stern voids which reduced the amount of forward weight on the rocks, and hence refloat the vessel.
