Naval engineering firm Samsung Heavy Industries has unveiled a modular floating data center concept engineered to deliver 50 megawatts of computing capacity directly to coastal megacities. Floating on maritime platforms, these mobile installations utilize surrounding seawater for high-efficiency direct cooling, drastically reducing the electrical energy usually required for air conditioning system heat dissipation. The deployment model offers dense coastal metropolitan areas a flexible alternative to land-constrained urban data centers without straining local power grids or real estate. Overcoming Onshore Land and Energy Constraints In a strategic effort to overcome severe land shortages, grid interconnection delays, and cooling limitations facing global data infrastructure, Samsung Heavy Industries (SHI) has transitioned its purpose-built floating data center (FDC) concepts into full execution. The South Korean shipbuilding giant has signed a major engineering contract with U.S.-based developer Mousterian Corporation to perform basic and detailed engineering for 50-megawatt (MW) critical IT capacity units. Designed to support high-density artificial intelligence (AI) workloads, these moored offshore structures allow tech companies to bypass long municipal land-acquisition battles and draw directly from coastal power resources. By applying standardized shipyard fabrication methods, SHI can build data center hulls simultaneously while onshore marine site preparation occurs, drastically reducing the multi-year timelines standard for conventional land-based hyperscale facilities. Engineering Ocean-Based Cooling and Dual Power Systems The engineering architecture of Samsung Heavy’s floating platform solves two of the most critical operational challenges in modern AI computing: thermal management and continuous power availability. Equipped with specialized heat exchangers, the floating hull leverages surrounding seawater for non-evaporative cooling, completely eliminating the massive freshwater consumption associated with traditional evaporative cooling towers. To protect delicate computing equipment from corrosive maritime environments, SHI engineered specialized hull insulation and atmospheric seal systems to keep humidity and salt spray out of server rooms. For power, the modular floating units can draw grid power via subsea cables or operate autonomously using onboard LNG-fueled solid oxide fuel cells. This dual-power design gives hyperscalers unprecedented operational flexibility when deploying computing clusters near densely populated coastal markets. Regulatory Approval and Scaling to Hyperscale Capacity Demonstrating the rapid commercialization of the offshore data platform, Samsung Heavy Industries has secured critical regulatory approvals from leading international classification societies. The company achieved design approval from the American Bureau of Shipping (ABS) for its initial 50 MW design alongside a formal Approval in Principle (AIP) for a massive 200 MW floating facility. This fourfold capacity expansion directly targets the massive scale requirements of global cloud providers and frontier AI labs. With initial commercial deployments targeted for 2028, SHI’s maritime computing platform establishes a scalable model that transforms traditional shipyards into vital production hubs for global digital infrastructure.
