Ocean Compute Infrastructure

Scaling Compute to 10 Terawatts

Clean ocean energy and free cold-water cooling enable compute to grow far beyond land-based limits — with low PUE, deployment without regulatory delays, and environmental benefits including marine habitat, nutrient upwelling, and aeration of hypoxic waters.

Platform Concept A — Tower

Platform Architectures

Two Engineering Paths, One Construction System

Both platform concepts are built with the same UHPC airform methodology — inflatable formwork, monolithic concrete shells, at-sea fabrication. The choice between tower and dome is a deployment decision driven by site depth, program requirements, and stability tradeoffs.

Platform Concept A Tower Architecture

Concept A

Tower

A slender vertical structure with the deep-water cold pipe integrated through the structural core — optimized for OTEC deployment in deep tropical waters.

Integrates deep-water cold pipe along the structural core
Lower center of gravity — superior stability in open ocean
Minimal waterplane area reduces wave loading
Efficient vertical stacking for OTEC heat exchangers

Limited above-water deck area per footprint
Higher aspect ratio increases wind exposure aloft

Concept B

Dome

A wide monolithic shell with maximum above-water volume — optimized for habitation, compute floorplate, and mixed-use development at scale.

Maximum above-water area for habitation and tourism
Stability from wide diameter and heavy submerged base
Efficient floorplate for mixed-use development
Lower profile reduces wind loading at elevation

Cold-water pipe requires separate riser infrastructure
Larger waterplane limits location to equatorial and other hurricane-free regions

Core Technology

Two Integrated Engineering Systems

RB Sea's platform architecture combines advanced concrete construction with ocean thermal energy conversion — enabling durable floating structures with continuous, low-cost power and industrial-grade cooling.

System 01

UHPC Airform Construction

At-Sea Monolithic Dome Fabrication

Ultra-High Performance Concrete (UHPC) deployed via airform inflation — the same principle Monolithic Domes uses for land-based megastructures, adapted for marine fabrication. Inflatable formwork enables rapid, repeatable construction of spherical and toroidal hull geometries without traditional shipyard infrastructure.

Compressive strength exceeding 150 MPa
Superior strength-to-weight vs. conventional concrete
Monolithic shells — no welded seams or fatigue points
Scalable from residential modules to industrial platforms
Fabrication possible at sea, reducing logistics costs

System 02

OTEC / ORC / SWAC Hybrid

Ocean Thermal Energy & Seawater Cooling

A tri-modal energy system leveraging the ocean's natural thermal stratification. Ocean Thermal Energy Conversion (OTEC) generates baseload power from the temperature differential between warm surface water and cold deep water. Organic Rankine Cycle (ORC) turbines capture waste heat. Seawater Air Conditioning (SWAC) provides industrial-grade cooling for compute workloads.

24/7 baseload power independent of weather
Cold seawater cooling for high-density compute
Dual revenue: electricity generation + thermal services
Optimal in tropical latitudes with deep ocean access
Near-zero marginal cost once infrastructure is deployed

Compute Platform

Ocean-Powered AI Infrastructure

Floating platforms with dedicated OTEC power and SWAC cooling create an ideal environment for high-density compute — with energy costs a fraction of land-based data centers and cooling essentially free.

Primary Focus

AI Compute & Inference

Training and inference workloads demand massive, reliable power and continuous cooling. Ocean thermal systems deliver both at scale. Offshore platforms provide physical security, jurisdictional flexibility, and expansion capacity that land-based facilities cannot match. The combination of cheap baseload power and free cold-water cooling creates a structural cost advantage for AI infrastructure operators.

Secondary Revenue

Proof-of-Work Compute

Bitcoin mining and other proof-of-work workloads serve as an ideal bootstrap revenue stream during platform deployment. Mining operations monetize excess power capacity immediately, generating cash flow while AI tenant infrastructure is provisioned. Power cost is the primary determinant of mining profitability — OTEC delivers the lowest sustained energy cost of any generation method.

Engineering Validation

The Coquina Prototype

Before scaling to industrial platforms, we built and tested a full-scale modular floating home — validating materials, construction methods, and off-grid systems in real marine conditions.

What We Proved

The Coquina project demonstrated end-to-end capability: structural engineering, modular fabrication, marine deployment, and sustained off-grid operation. The platform was designed, built, and lived in — providing real-world data on buoyancy, stability, thermal performance, and systems integration.

Growth Path

Phased Investment & Deployment

RB Sea follows a disciplined scaling strategy — proving technology at each phase before committing capital to the next order of magnitude. Small-scale deployments are not expected to be efficient or commercially useful on their own.

Phase I — Current

Proof of Concept

$5M

Validate core technology at sea — at-sea UHPC airform construction, deep-water piping, and integrated energy/cooling systems that reduce structural and operational costs at scale. Not revenue-generating; the objective is technical proof. El Salvador is an option, but a $5M test in international waters works if needed.

At-sea UHPC airform construction demonstration
Deep-water cold pipe and OTEC/SWAC system integration
Validated cost models for structure, energy, and cooling
Technology readiness for Phase II scale-up

Phase II — Scale

Full-Scale Structure

$300M

Build a full-scale monolithic floating structure — the primary goal of this phase. Power generation is included but not at full gigawatt scale; generation capacity is the more expensive component and ramps in Phase III. Validate construction, deployment, and operations at production size.

Phase III

Gigawatt Scale

$1B+

City-scale floating developments combining compute, energy, logistics, and habitation. Permanent ocean infrastructure serving as industrial hubs, launch platforms, and population centers — enabled by decades of materials and systems engineering.

Strategic Position

Central American Pacific — Optimal Conditions for First Deployment

Tropical Pacific waters off Central America offer the ideal combination of warm surface temperatures, accessible cold deep water, favorable regulatory environments, and proximity to major fiber routes. El Salvador's progressive digital asset policies and active infrastructure investment create a compelling jurisdiction for a first commercial deployment.

Strategic partnerships with established financial institutions in the digital asset space provide a credible funding pathway — aligning capital deployment with sovereign-level commitment to technology infrastructure development.
