Microsoft, Naval Group Deploy Underwater Datacenter Off Orkney

Microsoft chose Naval Group to implement Phase 2 of its underwater datacenter project, also called Project Natick.

The Datacenter was deployed in early June 2018 off the Orkney Archipelago, and will be operated for a period of one year.

Eric Papin, Naval Group’s director of Innovation and Technological Expertise, said: “We are proud to bring Naval Group’s expertise on design, implementation, deployment and maintenance of innovative  projects in maritime environments to the service of Microsoft. Naval Group has always invested in research and development, most recently  Marine Renewable Energies. We are pleased to participate in Microsoft’s vision for a clean energy future.”

Naval Group and its subsidiary Naval Energies have adapted their technologies to the design of the Natick Phase 2 Datacenter structure.

Today, Naval Group is supporting Microsoft towards its objective to build, deploy and operate an underwater datacenter which is as powerful as several thousand high end consumer PCs with enough storage for about five million movies.

The datacenter is contained in a submersible cylindrical system inspired by the underwater constructions of Naval Group. A triangular base (also called Subsea Docking Structure), ensures the positioning of the datacenter at the bottom of the ocean. A dual air-water system enables cooling of the datacenter, thus taking advantage of the temperature of the underwater environment.

Naval Group, with the support of its subsidiary Naval Energies, carried out this project relying on its strong industrial capabilities, involving the sites of Nantes-Indret (design), Cherbourg (model tests), Lorient (subsea base manufacturing) and Brest (design and manufacturing of the pressure vessel 2).

The EMEC test base provided a favorable environment for the deployment of Phase 2 of the Natick Project, which is powered by marine renewable energy sources.The underwater datacenter is designed to remain immersed for 5 years without direct intervention and will be operated “lights-out” for a year to evaluate its performance in real use conditions.

Ben Cutler, Project Natick manager at Microsoft Research, stated: “Microsoft is pleased to collaborate with Naval Group on Phase 2 of Project Natick. Project Natick reflects Microsoft’s ongoing quest for cloud datacenter solutions that offer less resource intensive options, rapid provisioning, lower costs, and high agility in meeting customer needs. A key advantage is getting closer to our customers: half the world’s population lives within 200 km of the sea, so placing datacenters offshore increases the proximity of the cloud to the population, reducing latency and providing better responsiveness. And by deploying in the water we benefit from ready access to cooling – reducing the requirement for energy for cooling by up to 95%.

Naval Group’s deep expertise in innovative marine technologies, including renewables, makes it an ideal choice for collaboration on Phase  ’s design, fabrication, and deployment of a standard,manufacturable, rapidly deployable datacenter.”
