As artificial intelligence is essential in all sectors, the pressure exerted on digital infrastructure becomes colossal. Behind each vocal request, an image generated or predictive algorithm, millions of calculations pass through energy -consuming data centers. Faced with this explosion of demand, industrial actors explore new solutions. Among them, the emergence of floating data centers draws a new technological landscape, where the oceans become the last border of modern IT.
According to Radio France, a 10,000 square meter data center can consume as much as a city of 50,000 inhabitants. This energy request is not only used to run the servers, it also feeds essential cooling systems, as the machines heat under the calculation load. While the available terrains are becoming scarce and tensions on electrical networks are intensifying, digital giants come up against physical limits.
The constraints accumulate. The land is expensive, the sites take time, and the networks remain too dependent on the room. To accompany the rise of artificial intelligence, some seek to overcome these blockages. A new dynamic begins, this time at sea, far from the limits imposed by the land.
Floating data centers reinvent maritime infrastructure
In Japan, the Mitsui Osk Lines group, specialist in maritime transport, has decided to transform the oceans into digital reception land. In partnership with the Turkish company Karpowership, which operates floating power plants, it develops an unprecedented fleet of sea data centers. The displayed objective is to launch, by 2027, a duo of complementary ships. One would carry the servers, the other would produce energy to feed them.
The project is based on already existing ships, converted to accommodate between 20 and 73 megawatts of computer power, according to Itdaily. For comparison, a modern data center like that of Penta infra in Belgium starts at only 7 megawatts. This modular approach changes the situation. The ships can be operational quickly, without waiting for many years of work. They do not occupy any strategic terrain and incorporate a cooling system drawing directly from seawater.
Mitsui and its partners are considering a system capable of connecting to the Internet either via underwater cables or by land exchange points. This mobile infrastructure could arrive near regions in tension or distant industrial zones, providing massive calculation power where it is necessary. The idea recalls the Google project initiated in 2013 in the Bay of San Francisco, where the American firm already experienced mobile platforms fueled by marshal sources.
Between flexibility and sobriety, an alternative still to the test
If the floating data centers offer new promises, they are not free from major challenges. Natural cooling by sea water or river effectively reduces energy consumption, but the ecological footprint of such a structure is not limited to this single parameter. The manufacture, the conversion of ships, their maintenance, the underwater cables and the possible relocation of such a center ask many questions, especially in terms of environmental impact.
The precedent of submerged data centers, such as Microsoft's Natick project, serves as a reference. Smoked off the Orcades in Scotland, this cylinder filled with servers had demonstrated better energy efficiency and a material failure rate lower than land centers. However, the costs and maintenance issues quickly tempered the ambitions. The simple replacement of a component requires complex operations, and the impact on marine ecosystems remains poorly evaluated in the long term.
Unlike underwater data centers, floating versions have the advantage of remaining accessible and modular. This flexibility, combined with a relative speed of deployment and the energy independence offered by naval power plants, could attract a niche market in search of adaptability. It remains to prove that such a solution can respond to the rise of AI without generating new imbalances, neither on land, nor at sea.
