Neumann Class Modular Data Centres

Compute capacity, wherever demand takes you.

Type Modular floating data centre platform Configuration 10MW, scaling to 20MW and 40MW Delivery Single EPC contract with Dimension Status Concept design · September 2026

Neumann Class is Dimension's modular floating data centre platform, bringing compute, power and cooling together on a purpose-built marine asset. Designed around a 10MW configuration, with a platform architecture that scales to 20MW and 40MW, it offers a redeployable approach to delivering high-density compute infrastructure. Independent onboard power, marine battery storage and N+1 liquid cooling reduce dependence on land availability and grid connections — giving operators more flexibility over where they deploy capacity.

The Story

Demand Moves Fast. Infrastructure Should Keep Up.

Digital growth is creating demand for compute in places where conventional infrastructure can take years to catch up. Land acquisition, grid connection queues and cooling requirements can determine when — and where — a data centre becomes viable.

Neumann Class starts with a different question: what if the infrastructure could move closer to demand?

Dimension brings naval architecture and data centre engineering together in one integrated platform. Server facilities, power generation, battery storage and seawater heat rejection are housed aboard a purpose-built steel vessel, designed for deployment in sheltered coastal waters.

The platform combines dual-fuel LNG and diesel generation with containerized battery storage, rooftop solar and N+1 liquid cooling. Its enclosed arrangement provides dedicated spaces for compute and energy systems, with clear access for operations and maintenance.

Compute, power and cooling on one purpose-built steel marine platform — built in a yard, towed to a sheltered-water site and redeployable as demand shifts.

Arrangement

One Deck, Three Systems

Scaling the Platform

One Architecture. More Capacity.

The Neumann Class architecture starts at 10MW and extends to 20MW and 40MW configurations on larger hulls. Larger generating units and shared marine infrastructure are designed to improve capital efficiency as capacity grows.

Unlike a fixed land asset, the platform can be redeployed as demand changes. That gives operators a longer-term choice: expand capacity, serve a new coastal market or reposition infrastructure as their business evolves.

10MW — Baseline Configuration
Genset configuration (N+1)	4 × 3.5MW
Installed generation capacity	14MW
Standby redundancy overhead	25%
20MW
Genset configuration (N+1)	5 × 5MW
Installed generation capacity	25MW
Standby redundancy overhead	20%
40MW
Genset configuration (N+1)	6 × 8MW
Installed generation capacity	48MW
Standby redundancy overhead	~17%
