About Main Ore

Mary R. Koch was a 274.330-metric-ton (269.997-long-ton; 302.397-short-ton) combined ore carrier and oil tanker. The ship was named after Mary Robinson Koch, wife of American industrialist Fred C. Koch. Mary R. Koch was built at the Uljanik, Brodogradiliste l Tvornica Dizel Motora shipyard in Pula in Socialist Federal Republic of Yugoslavia, (now Croatia). Her two sister ships, Tafala and Torne were delivered to the Swedish company Trafikaktiebolaget Grengesberg in 1974. A further sister ship named Kanchenjunga was built as a pure oil carrier with no ore capability. Under Greek management Mary R. Koch (callsign A8QU) was time-chartered to Exxon for three years from going into service. Subsequently she made spot voyages arranged by the oil-trading division of Koch Industries. Around 1980 Koch Shipping was created and Mary R.
