Service history

In May 1984, Indiana Harbor was the largest ship to ever enter the harbor at Ludington, Michigan and delivered 45,000 tons of limestone to Ludington's Dow plant.[3] It also set another record the following year with 50,090 tons of limestone.[4] In August 1986, Indiana Harbor broke the Lake Erie record for loading coal, 52,000 tons, at Toledo, Ohio.[5] Ten days later, Indiana Harbor ran aground in the St. Clair River.[6]

On September 8, 1993, the ship collided with the Lansing Shoals Light Station. There were no injuries and the damage was about $1.9 million for the ship and $100,000 for the light.[7] On January 3, 1996, Indiana Harbor grounded in the St. Marys River and suffered an 8-foot (2.4 m) gash in the port bow.[8]
