Problem
Land‑based data centers face high capital and operating expenses due to extensive cooling infrastructure, limited proximity to subsea fiber routes, and growing environmental constraints. These factors increase latency for edge workloads and restrict the scalability of compute resources needed for AI and high‑performance applications.
Solution
Subseacloud delivers modular, containerized data center units that are installed directly on subsea telecommunications cables. By leveraging the ocean’s natural heat sink, the units achieve passive cooling with a Power Usage Effectiveness (PUE) of 1.01, eliminating traditional chillers and reducing energy consumption. Each standardized container is built for 25+ years of service, integrates both power and fiber connections, and can scale to 700 MW per deployment site. The solution enables rapid, 12‑week rollout of AI‑ready compute capacity, provides on‑deck maintenance within 24 hours, and supports co‑location with offshore renewable assets, delivering high performance at a markedly lower total cost of ownership.
Target Audience
Primary customers are telecom operators, hyperscale cloud providers, and enterprises that require low‑latency, high‑performance compute at the network edge, as well as offshore renewable developers seeking co‑located data center capacity.
