Here is the Indiana Harbor making her second entrance into Duluth, Minnesota on the evening of June 4, 2023. She had initially arrived earlier that morning, originally scheduled to load taconite at the CN dock. However, as she waited for her turn to load, her orders changed to load coal at the SMET dock. Before she could do so, she needed to head back onto Lake Superior to clean out her cargo holds... as any non-toxic dry taconite residue needs to be cleaned out at least 3 miles from the Duluth shoreline. That departure was covered in a previous video on this channel. After about four hours on the lake, she made her way back into Duluth for a second time... arriving as light was quickly fading for the evening. She would then need to wait a couple more hours in the harbor while her fleet mate the American Integrity finished taking on her own load of coal.
Fortunately, the Indiana Harbor's crew will still happy enough to give up a nice captain's salute on the way in... with the bridge willing to reply. It was nearly the end of a very long day for the Indiana Harbor and the bridge operator... not to mention the guy with a video camera... but it was still a pleasure to watch a giant move through the canal.
It was less of a joy for the private boat that decided to follow the Indiana Harbor through the canal, however. While there were no big waves in the wake of the Indiana Harbor, there was plenty of turbulence in the water. The private craft bobbed and weaved back and forth, fighting the restless current stirred up by the 1000-footer's dual propellers. I missed catching some of the more violent rolls the private vessel made before I could refocus my camera on her. At one point it looked like she might capsize in the wake. But once they got out of the worst of the turbulence, they sailed on smoothly again. Clearly wake turbulence is not just limited to large jetliners!
The 1000-foot Indiana Harbor was launched in March 1979, making her the ninth 1000-footer on the Great Lakes (out of 13 total). She is powered by four GM V-20-cylinder 3,500 horsepower diesel engines, giving her a service speed of 14 knots. Her seven cargo holds are accessed by 37 hatch covers. She has a maximum cargo capacity of 80,900 tons. Her self-unloading system consists of a loop conveyor that carries cargo up to her 250-foot self-unloading boom. She can discharge up to 10,000 tons per hour. She sails for the American Steamship Company.
