The Ems Ore was built with her pilothouse amidships. The ship's original dimensions were 546’00” (166.42m) loa x 73’10” (22.50m) beam x 40’02” (12.24m) depth with a carrying capacity of 20,032 tons (20,354 mt). The Ems Ore was one of 8 sister-ships built in 1959/60 specifically for a long-term charter arrangement with Navios Corp. of the Bahamas (a U.S. Steel owned subsidiary) to be used in the iron ore trade between Venezuela and Europe for U.S. Steel interests. Of the 8 ships built, 4 were owned by the German company Transatlantic Bulk Carriers and registered out of the port of Monrovia, Liberia. These were the Ems Ore, Rhine Ore, Ruhr Ore and Weser Ore. The other 4 were owned by Polaris Shipping Co., an American company. These 4 were named the Clyde Ore, Tees Ore, Thames Ore and Tyne Ore.
