OFFSHORE COMPUTE INFRASTRUCTURE

We research, design and develop offshore compute infrastructure using repurposed energy assets.

EXPLORE THE RESEARCH
SCROLL TO CONTINUE

Compute growth has become a physical infrastructure problem.

Power, grid access, land and cooling now shape where large compute systems can be built.

The marine structure carries value before compute arrives.

Selected late-life assets may offer offshore location, engineered structure and access systems. Each candidate demands asset-specific structural, power, safety and decommissioning analysis.

One structure. A different industrial purpose.

Legacy drilling systems leave the topsides. Modular power, cooling, compute and fibre systems occupy the released deck volume.

LEGACY CONFIGURATION

Legacy offshore configuration ready.

STRUCTURAL LIMITPontoons, ballast spaces, columns, bracing and mooring interfaces remain marine structure. They do not become compute floor space.

OFFSHORE POWERCOMPUTE AT SOURCEDATA OVER FIBRE

Electricity crosses a short engineered path to the compute load. Fibre carries the resulting data to network landing points.

A persistent marine host and service manifold remain in place while compute modules are exchanged. The persistent host services are electrical, cooling, control, and fibre.

Compute hardware moves on its own cycle.

Removable modules separate server refresh from the service life of the marine structure.

CONNECTED Generation A is connected to all four host services.

PLATFORM TOPSIDE SURVEY

HELICOPTER DECK / CRANE ENVELOPE / ACCESS ROUTES

SEVEN ADJACENT PRECEDENT FAMILIES GROUP INTO FOUR TECHNICAL DOMAINS.

  1. PLATFORM REUSE / MARINE HOST , TECHNICAL DOMAIN: MARINE HOST
  2. FLOATING INDUSTRIAL FACILITIES , TECHNICAL DOMAIN: MARINE HOST
  3. OFFSHORE ELECTRICAL , TECHNICAL DOMAIN: OFFSHORE ELECTRICAL
  4. MARINE COOLING , TECHNICAL DOMAIN: THERMAL SYSTEMS
  5. SUBSEA COMPUTE , TECHNICAL DOMAIN: COMPUTE + CONNECTIVITY
  6. MODULAR COMPUTE , TECHNICAL DOMAIN: COMPUTE + CONNECTIVITY
  7. SUBSEA FIBRE , TECHNICAL DOMAIN: COMPUTE + CONNECTIVITY

UNRESOLVED INTEGRATION BOUNDARY: HOST, POWER, COOLING, COMPUTE, AND FIBRE EXIST ACROSS THESE DOMAINS BUT ARE NOT YET RESOLVED AS ONE INTEGRATED SYSTEM.

HORIZON RACK PROPOSITION: HOST, POWER, COOLING, COMPUTE, FIBRE ASSEMBLED AS ONE SYSTEM.

Seven precedents define one integration boundary.

Offshore power, marine cooling, modular compute and fibre are established in adjacent domains. Horizon Rack examines how they can operate as one system on a reused or relocatable marine host.

THE UNRESOLVED WORK IS SYSTEM INTEGRATION.
