Clay and limestone in; coal and iron ore pellets out

Above, after arriving Duluth under the Duluth Aerial Lift Bridge at 8:45 this morning (June 02, 2016), the Paul R. Tregurtha stopped by the Calumet Fuel dock for fuel before going to Midwest Energy Resources to load 66,000 tons of coal for Detroit Edison. In front of her, the Trudy is still discharging a cargo of clay at the Port Terminal. Just below, the Cason J. Callaway arrived Duluth at 11:25 this morning with limestone. Twenty five minutes later, she passes by the two vessels at the Port Terminal on her way to discharge her cargo at the C. Reiss Dock before moving over to the CN dock to load iron ore pellets. Ten minutes later (below), the Tregurtha moves away from the dock to make the short trip up the St. Louis River to the Midwest Energy dock.


  1. Ken, I’ve been reading about the Presque Isle and was interested in your story about the tug barge combination. Do you have a photo of a barge slot without the tug? I have trouble imagining how the two are put together. Also are they difficult to separate? Do the tugs ever go with different barges or do they stay with one barge their whole life. I assume they’re capable of interchange if they can be separated for inspections. Perhaps you have an article on the ITBs.

  2. The AIS system appears to have a fix on a boat named the Advantage at Gavilon. However, it doesn’t appear in the shipping news or at Dennis’ site. What’s the story?

    • No it was not on the shipping schedule. I saw your message on DHC Forum. It is not listed by name either on my Marine Traffic App or on boatnerd AIS. This is indeed strange.

    Curious to learn how much fuel can contain this vessel , and an average of distance a ship like “Thrgurtha” can do….??
