Floating data centers cruise a bit closer after a major show of support from
Japanese giant Hitachi

Description:
Japan is advancing floating data center plans using converted ships, with
Hitachi support, to address land shortages and growing AI infrastructure
demand.

FULL STORY
A floating data center
project in Japan has gained significant backing from Hitachi, bringing a
ship-based computing concept closer to possible deployment. 

The company and its subsidiary Hitachi Systems signed a memorandum with
shipping firm Mitsui OSK Lines to develop and operate the facility. The
agreement covers the conversion of a second-hand vessel into a working data
center, with operations tentatively expected from 2027 onward. Hitachi will
contribute its experience from operating land-based facilities in Japan and
deploying containerized data systems in overseas markets.

Why Japan is looking to the water for server farms

Demand for data center capacity continues to increase as artificial
intelligence systems require more computing power and supporting
infrastructure. 

This demand creates pressure to identify locations that can support cooling,
energy supply, and long-term operational stability. 

Japan faces land constraints, particularly around Tokyo and Osaka, where most
existing data campuses remain concentrated, and the floating concept offers 
an alternative, reducing construction timelines, meaning ship conversion 
could potentially be completed in about one year.

Conventional data centers often require several years to design, approve, and
construct under current regulatory conditions. 

Earlier plans referenced converting a 120-meter, 9,731-ton vessel, although
attention has shifted toward repurposing a car carrier instead, as such
vessels provide large internal cargo areas that can accommodate server
installations and associated infrastructure. 

A capacity of roughly 54,000 square meters would place the facility near the
scale of large terrestrial data centers.

Cooling would rely on seawater or river water, reducing dependence on
freshwater sources that are increasingly constrained, although this approach
introduces different engineering requirements, particularly around corrosion
control, filtration, and thermal exchange efficiency. 

Mitsui OSK Lines is also examining how it can reuse existing onboard systems
during conversion, including air conditioning, water intake, and power
generation infrastructure already integrated into the vessel. 

Reusing these systems may reduce upfront costs, although the extent of 
savings remains unclear without detailed disclosures. 

Hitachi and Hitachi Systems will oversee IT infrastructure design,
installation, and operational management, and will also engage customers and
define technical requirements for deploying workloads on the platform. 

Mitsui OSK Lines will manage vessel conversion, coordinate with port
authorities, and handle maritime logistics and maintenance. 

The arrangement reflects a division between digital infrastructure expertise
and maritime operational control.
