Partnering with leading institutions across the blue economy
01 The industry challenge
The ocean is dynamic.
Most operational intelligence is not.
Today's weather and ocean forecasts are too coarse, fragmented, and static for decisions at the scale of ports, offshore assets, and individual voyages.
ARMS transforms global ocean and atmospheric data into local, continuously updated intelligence built around the operation—not the other way around.
Fragmented data
Operators spend valuable time reconciling disconnected models, observations, and systems.
Static intelligence
Fixed products cannot follow a vessel, fleet, mission, or rapidly changing operating area.
Data without decisions
Environmental information rarely arrives in a form ready for immediate operational action.
02 Core technology
ARMS™
One ocean digital twin.
Two deployment modes.
Fathom’s Automated Relocatable Modeling System combines coupled ocean physics, observations, AI, and cloud automation to deliver predictive intelligence wherever it is needed.

03 How ARMS works
From global data to operational decisions
Observe. Model.
Learn. Predict. Act.
Ingest
Satellites, buoys, radar, global models, vessel systems, and private data.
Simulate
Coupled atmosphere–ocean–wave physics at the resolution operations require.
Augment
AI accelerates computation, assimilates observations, and improves prediction.
Deliver
Decision-ready intelligence through APIs, dashboards, GIS, and onboard systems.
04 Industry solutions
Ocean intelligence
built around the mission.
One core platform supports operations across the blue economy—configured for each environment, asset, and decision.
Ports & Harbors
Port-call planning, dynamic under-keel clearance, metocean intelligence, hazard response.
Shipping & Navigation
Route-specific currents, waves, weather, arrival planning, fuel and emissions optimization.
Offshore Operations
Site-specific forecasts for planning, construction, safety, maintenance, and asset portfolios.
Defense & Security
Rapidly relocatable environmental intelligence for mission planning and maritime awareness.
Fisheries & Conservation
Predictive habitat intelligence for efficient fishing and safer coexistence with marine life.
05 Operational by design
Built for the real ocean.
Proven in real operations.
ARMS is not a static model or research prototype. It is a cloud-optimized operational platform validated against observations and deployed for maritime decision-making.
