Visual characteristics
Hull, superstructure, proportions, equipment, markings, damage, configuration and other distinguishing features.
Dark Ship IdentificationFrom an image
From an image
to an attributable vessel.
A custom government and enterprise capability combining image evidence, geospatial context, vessel characteristics, historical activity and available signals.
Image-led attribution
Identify the ship or reduce the candidate set to an operationally useful level.
Tevuna starts from an image or imagery set and tests visible and contextual evidence against vessel records and activity history. Where sufficient evidence exists, the output identifies the vessel and connects it to ownership, management and risk intelligence.
- Government and enterprise requests
- Unknown or deliberately obscured vessels
- Imagery captured with limited identifying information
- Cases requiring a traceable candidate-elimination process

Evidence layers
Combine what is visible with what is historically consistent.
Evidence availability depends on image quality, location, time window and the observable characteristics of the vessel.
GEO
Geospatial context
Coastline, port, anchorage, traffic lane, weather, lighting and environmental indicators.
HIS
Historical activity
AIS, port calls, known routes, registry history and prior vessel behavior where available.
SIG
Available signals
Non-image signals and event correlations that can support candidate confirmation.
REG
Vessel records
IMO identity, names, flags, dimensions, type, ownership and management history.
ALT
Alternative candidates
Competing matches and the evidence supporting or excluding each candidate.
Workflow
Preserve the attribution path from observation to identity.
- Validate image provenance, location and time window where available
- Extract vessel and environmental characteristics
- Generate and rank a candidate set
- Compare registry, AIS and historical activity
- Correlate additional signals where available
- Assess identification confidence and alternative candidates

The final package is configured around the operational or evidentiary use case.
01
Identity assessment
Identified vessel or ranked candidate set, with IMO and historical identity where available.
02
Evidence comparison
Visual, geospatial, activity and registry factors supporting and contradicting each conclusion.
03
Ownership intelligence
Shipowner, manager, beneficial-owner company, UBO or UCB and related risk after identity is established.
04
Confidence and limits
Explicit confidence, evidence gaps and alternative candidates.
Custom scope
Pricing depends on the image set and attribution problem.
Dark Ship Identification is offered on request to government and enterprise clients. Scope depends on image quality, number of observations, available coordinates or time windows, geographic area, required urgency and the depth of ownership intelligence requested after identification.
