NYK and Partners Develop Port-Based Floating Data Center
Cubierto por 3 fuentesPublicado
A Japanese consortium led by shipping company NYK unveiled a new floating data center concept that would be moored alongside a quay within a port, rather than operating offshore. The initiative seeks to expand digital infrastructure options without relying solely on land-based facilities, making use of existing services such as electricity, telecommunications, and coastal power generation.
Members and roles
The group is made up of NYK, data center design specialist NTT Facilities, wind and solar power generator Eurus Energy Holdings Corp, and MUFG Bank, a subsidiary of Mitsubishi UFJ Financial Group. According to Splash 247, NYK will lead the project's development and business strategy, NTT Facilities will oversee the design, construction and operation of the floating data center, Eurus Energy will assess the integration of renewable energy, and MUFG Bank will evaluate financing and potential business partnerships.
Precedent in Yokohama
The work builds on a demonstration project at Yokohama's Osanbashi Pier, where NYK, NTT Facilities, Eurus Energy, MUFG and the city of Yokohama have been testing a renewable energy-powered floating data center since March 2026.
Why a port-based model
The consortium argues that this port-based format can be deployed in metropolitan areas and regional communities, where access to onshore infrastructure is easier than at remote offshore sites. According to NYK and its partners, the proposal would help address the shortage of suitable land, power supply constraints and the long construction timelines affecting conventional data centers, while also enabling the use of local renewable generation, including offshore wind.
The long-term goal
Sources agree that floating data centers located far from the coast are seen as the ideal long-term model, as they allow for more direct use of large-scale renewable energy, greater scalability and independent operation, although they still face challenges in terms of accessibility, high-capacity telecommunications connectivity, and power supply configurations separate from conventional grids. The consortium suggests that starting with the port-based model will help accelerate the practical application of these facilities and pave the way toward deployments farther from shore, in a space where other developers such as Mitsui OSK Lines and Hitachi, and Samsung Heavy Industries together with Hanwha Ocean, are already competing.
