Crowley Alaska Tankers announced today that it has signed an agreement, subject to regulatory approval, to purchase three tankers from SeaRiver Maritime and charter them back to SeaRiver under varying multi-year terms.

Included in the acquisition are the tankers Liberty Bay and Eagle Bay, each of which has a capacity of 800,000 barrels and transport crude from Alaska to West Coast refineries; and the tanker SR American Progress, which has a capacity of 342,000 barrels and transports refined petroleum between US Gulf and East Coast ports.

Crowley operates and manages the largest US flag petroleum and chemical tank vessel fleet in the country.

By the end of 2017, the company will be operating 37 Jones Act qualified large petroleum transportation vessels in the United States with a combined capacity of more than 10 million barrels.

Among this tank vessel fleet are a tanker and an articulated-tug-barge (ATB) already on charter to SeaRiver.
