Standardized floating data center platforms paired with standalone marine power vessels.
Overview
Atomarine, Inc. is developing floating data center campuses that combine standardized compute barges with separate power vessels. The company’s proposed architecture is intended to avoid grid interconnection constraints, use seawater for cooling and centralize fabrication in shipyards. Its public roadmap uses gas turbines for an initial pilot and envisions marine nuclear reactors as a later power source, while keeping generation separate from the data halls. Founded in 2026 by Dimitris Koutentakis and Emile Germonpre, Atomarine is a Y Combinator Summer 2026 company with a two-person team. Public materials describe early partnerships but do not name vendors or completed deployments.
