Google said it was exploring them as interactive spaces for learning about technology. A 2008 trade report had already said the portable data-center project was discontinued.
Google’s plan: a modular data center on a floating platform
Google’s U.S. patent, US7525207B2, describes a floating platform carrying multiple computing units, a sea-based electrical generator and seawater-cooling equipment. It is evidence of a patented concept—not proof that Google built or operated an offshore data center.
The design treated computing equipment as modular cargo. Standard intermodal shipping containers could house the equipment, and a cargo ship or another floating platform could carry them. The patent envisioned deploying the platform where computing or telecommunications capacity was needed, anchoring it offshore, and swapping modules in port for upgrades or repairs.
How the proposed power and cooling worked
In the patent’s concept, wave or tidal motion could drive generators and pumps. A closed-loop cooling circuit would carry heat away from the computers, while heat exchangers transferred that heat to seawater. This describes the proposed architecture; the available reporting does not establish how efficiently it would have performed in operation.

How the patent relates to the barges seen in 2013
Reports in October and November 2013 described large, multi-level structures made from container-like units on barges near Treasure Island in San Francisco Bay and in Portland Harbor, Maine. Their appearance and Google’s secrecy prompted speculation that they were floating data centers. Google’s November statement addressed those visible barges directly:
“Google Barge … A floating data center? A wild party boat? A barge housing the last remaining dinosaur? Sadly, none of the above. Although it’s still early days and things may change, we’re exploring using the barge as an interactive space where people can learn about new technology.”

The statement supports interpreting the 2013 structures as a proposed interactive learning space, not a working data center. It did not specify the final exhibit design or an operating schedule.
| Question | Patent concept | Visible 2013 barges |
|---|---|---|
| What was described? | A floating platform-mounted data center with computing units, sea-based generation and seawater cooling (US7525207B2). | Multi-level, container-like structures on barges, reported near Treasure Island and Portland Harbor in October and November 2013. |
| What did Google say it was for? | The patent describes temporary computing or telecommunications deployment; it does not establish actual deployment. | In November 2013, Google said it was exploring an interactive space for people to learn about new technology. |
| Was it a deployed offshore data center? | Not established by the patent. | Google explicitly rejected the floating-data-center interpretation of the visible barges. |
What happened to the projects
A 2008 DatacenterKnowledge report titled “Google Planning Offshore Data Barges” said the portable data-center project had been discontinued. It quoted Google as having nothing to announce about that specific technology.

Later historical reporting says the 2013 barge experiment was halted and the barges were eventually sold or dismantled. The available sources do not provide a complete primary-source cancellation record or a definitive cost breakdown. Regulatory costs have been offered as reported explanations, not as a confirmed Google explanation.

The patent and contemporary news reports establish that Google explored a floating data-center architecture and that it had conspicuous barges in 2013. They do not establish a completed offshore data center or provide verified figures for the number of completed barges, computing capacity, construction cost or operating performance. Those figures should not be inferred from the patent or the barges’ appearance.
Rank #4
Google’s 2025 Environmental Report provides context for its current data-center strategy, not evidence that the barge concept returned: it says data-center energy emissions fell 12% in 2024 despite increased energy demand, and that Google signed contracts for more than 8 GW of clean-energy generation in 2024. Those figures concern company-wide sustainability work and should not be attributed to offshore barges.
