Presently, we operate and manage three 125,000 Moss LNG Vessels, seven Large Medium Speed Roll-on/Roll-off (LMSR) Vessels for the U. S. Navy and two Heavy Lift Vessels.

AMSEA was founded in 1984 in Quincy, Mass. to operate the five new-construction ships built by the former General Dynamics, Quincy Shipbuilding Division. Since that time, AMSEA has managed a number of Ready Reserve Force vessels for the U.S. Maritime Administration and Sealift Ships for the U.S. Navy's Military Sealift Command.

Employment has grown to over 450 with the seagoing crews coming from two maritime unions.
The officers belong to the American Maritime Officers Union (AMO) and the unlicensed from the Seafarers International Union (SIU).
