|The Edgar B. Speer arrived today for her first trip to the Twin Ports this season, coming under the Duluth Aerial Lift Bridge at 8:16 this morning (June 25, 2014). She will be loading iron ore pellets at the CN dock in West Duluth after she takes on fuel at the Calumet Fuel Dock at the Port Terminal. She made 9 trips here last year.The Canadian flagged Thunder Bay (below) came under the bridge this morning at 4:39; she is here for the 3rd time this season; she was here 6 times last season. Below, she is waiting at the inner anchorage for the Indiana Harbor to complete loading coal at Midwest Energy Resources (note her anchor chain off her bow).|
|The Hon. James L. Oberstar came in to port early morning on Friday, September 20, 2013 to load iron ore pellets at the CN dock in West Duluth. She is seen here, in back, entering the Duluth harbor on her way to the Aerial Lift Bridge and Lake Superior with her cargo of pellets. Meanwhile, the Great Lakes Trader (unseen here) moved in to load iron ore pellets at the CN. The Thunder Bay, in front of the Oberstar, had just arrived to load pellets. After the Great Lakes Trader departed with her pellets early Saturday morning, the Thunder Bay moved into the busy dock to collect her share.|
|The Thunder Bay came in from the anchorage at one minute before midnight on Friday, August 16, 2013. She is a new boat, the third of 4 new, large, red boats built for Canada Steamship Lines in Chengxi Shipyard in Jiangyin, China. She loaded coal at Midwest Energy. The Whitefish Bay, the second of the 4 new boats, was here about a month ago. The first of the group was the Baie St. Paul. She has been here 8 times since she arrived in 2012. The Baie Comeau will be the last. They and other Canadian boats have been loading coal here and taking it to the St. Lawrence River above Montreal where it is transferred to larger ocean ships that take it to Europe. It takes 3 of these new Trillium class boats to fill one of the ocean boats. The ocean boats are too big to get through the Welland Canal and other locks on the Seaway; the new Canadian boats where built as large as they could be and still be able to transit the Welland.|
|The Coast Guard cutter Mackinaw has been in the Twin Ports for a couple weeks for bow thruster repairs at the Fraser Shipyards. She is currently (Friday, December 16, 2011) moored at the DECC (above) but is expected to depart in the next couple days to begin another season of ice breaking on the Great Lakes.|
The US Coast Guard cutter Thunder Bay departed their home port in Rockland, Maine to come to the Great Lakes to assist in any ice breaking operations that may be needed. Bringing an east coast ship into the Great Lakes has been a Coast Guard tradition for some years, and provides them with an additional opportunity to cross train the crews and put the ship into a different environment, although the Thunder Bay is an ice breaking tug and is very good at that job. The 140-foot icebreaking tug was built to break ice; they use a low-pressure-air hull lubrication or bubbler system that forces air and water between the hull and ice. This system improves icebreaking capabilities by reducing resistance against the hull.
They arrived in Cleveland on December 12, 2011. Although currently based in Maine, she is named for the town of Thunder Bay, Michigan, on Lake Huron near Alpena.
