Atomarine

Atomarine designs and manufactures floating data center platforms built in shipyards and deployed at sea, cooled by seawater and powered on the platform. The Boston-based startup pairs standardized compute barges with separate offshore power vessels, initially natural-gas turbines while it develops marine nuclear reactors for future deployment. Moving compute offshore sidesteps grid interconnection queues that now stretch close to a decade, avoids local community opposition tied to land, water and electricity competition, and uses seawater for near-free cooling. Atomarine has modeled a power usage effectiveness of 1.1 for its facilities and is targeting a first gas-powered pilot deployment in 2028, with early partnerships across offshore barge builders and small modular reactor developers.
