The tug Defiance and barge Ashtabula departed Duluth on June 13, 2014, with a cargo of iron nuggets loaded at the Hallett #5 dock in West Duluth. Both were built in 1982 although they have had other names during that time. They are both owned by a Canadian Company, Lower Lakes Towing, and operated by the U.S. company Lower Lakes Transportation. The vessel therefore sails under a U.S. flag.

    Is the tug guided from the closed in crows nest area up high on the tugs tower?

    Why is it a tug?
    Is it really only 48 feet long?

    • It is a tug because the tug/barge combo is the cheapest way to ship cargo. You don’t need that large of a crew, it’s more energy efficient, and the number one to the company: it doesn’t cost much to build (still a hefty amount, but not as much as re-powering an older vessel or building a new one in general).
      And yes, it really only is 48 feet long.

      • Tristin (loves ships) says:

        only the tug is 48 feet long. with the combination of the tug and barge, it is much longer that 48 feet.

    When reading the shipping reports,they report some boats loading iron ore pellets or taconite pellets and sometimes just plain nuggets, could you tell me what the difference is?

    • Taconite is a finer version of iron ore. Simply that’s all there is. They both still come in pellet form. Not sure about the nuggets, though, that would be closer in relation to stone.

      • I think that taconite refers to the ore, usually less than 30% iron content, dug up from the ground. I list here info from Wikipedia. I usually refer to the stuff loaded into boats in Duluth as iron ore pellets, which contain taconite –
        Taconite is a variety of iron formation, an iron-bearing (> 15% iron) sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate. Newton Horace Winchell, the Minnesota State Geologist, coined the term during his pioneering investigations of the Precambrian Biwabik Iron Formation of northeastern Minnesota. He noted the rock had a superficial resemblance to iron-bearing rocks from the Taconic Mountains of New York.

        The iron content of taconite, commonly present as finely dispersed magnetite, is generally 25 to 30%.

        To process taconite, the ore is ground into a fine powder, the magnetite is separated from the gangue by strong magnets, and the powdered iron concentrate is combined with a binder such as bentonite clay and limestone as a flux. As a last step, it is rolled into pellets about one centimeter in diameter that contain approximately 65% iron. The pellets are fired at a very high temperatures to harden them and make them durable. This is to ensure that the blast furnace charge remains porous enough to allow heated gas to pass through and react with the pelletized ore. Firing the pellet oxidizes the magnetite (Fe3O4) to hematite (Fe2O3), an exothermic reaction that reduces the cost of pelletizing the concentrate. E. W. Davis of the University of Minnesota Mines Experiment Station is credited with developing the pelletizing process. Since the commercial development of this process in the Lake Superior region in the 1950s, the term taconite has been used globally to refer to iron ores amenable to upgrading by similar processes.

    I have never yet seen this tug/barge combo on the St. Clair River and anxiously awaiting to see them in order to add them to my large photo collection sometime.

  5. Tristin (loves ships) says:

    It’s too bad that this boat doesn’t go to Duluth.

    • She will most likely make 1-3 trips a season for ore. LLT mainly has the Michipicoten get ore from Duluth.
