American Steamship acquires six freighters for $120 million

American Steamship Co. has bolstered its fleet by acquiring six vessels for $120 million. The Amherst-based company bought the vessels from Oglebay Norton Marine Services in Cleveland, expanding its fleet to a total of 18 vessels. American Steamship already had the largest U.S.-flag fleet on the Great Lakes prior to the deal. Oglebay Norton is selling six of its nine freighters, to pay down debt and strengthen its balance sheet. American Steamship earlier this year was identified as a potential suitor for the ships.
