Service history

In May 1984, Indiana Harbor became the largest ship to ever enter the harbor at Ludington, Michigan, delivering 45,000 tons of limestone to the Dow plant in Ludington. The following year, it also set another record delivering 50,090 tons of limestone. In August 1986, Indiana Harbor broke the Lake Erie record for loading coal by taking on 52,000 tons of coal at Toledo, Ohio. Ten days later, Indiana Harbor ran aground in the St. Clair River.
On September 8, 1993, the ship collided with the Lansing Shoals Light Station. There were no injuries, but the collision caused approximately $1.9 million damage to the ship and $100,000 in damage to the light. On January 3, 1996, Indiana Harbor grounded in the St. Marys River and suffered an gash in the port bow.
