Welcome To American Steamship Company
(A Subsidiary of GATX Corporation)

Throughout our history, American Steamship Company (ASC) has been a pioneer in Great Lakes vessel transportation. Our Great Lakes fleet consists of self-unloading vessels that range in length from 635-feet to 1,000-feet. The diversity of our asset base enables us to transport a variety of dry bulk commodities including iron ore pellets, coal, and limestone aggregates. Our single trip vessel carrying capacity ranges from 24,000 to 70,000 net tons. During the Navigation Season, our vessels operate twenty-four hours a day, seven days a week and require no onshore assistance to unload cargo. Unloading speeds range from 7,000 to 10,000 net tons per hour.

Today, under the ownership of GATX Corporation, ASC continues to provide safe, efficient and environmentally responsible waterborne transportation. We are dedicated to continuously building value for GATX, our customers, our employees, and the communities in which we live and operate.
