Maritime Anomaly Detection

This application focuses on automatically detecting suspicious or abnormal vessel behavior across large ocean areas, with a particular emphasis on “dark” ships that switch off AIS/transponders to evade monitoring. By continuously analyzing satellite imagery, radar, RF, and AIS data, the system flags vessels, routes, and patterns that diverge from normal maritime activity, such as unusual loitering, covert rendezvous, or inconsistent identity and location data. It matters because manual maritime surveillance cannot keep pace with the scale of global sea traffic or the sophistication of illicit actors involved in smuggling, illegal fishing, sanctions evasion, piracy, and covert military operations. AI systems ingest multi-sensor data, automatically detect vessels (including non-cooperative ones), and rank anomalies by risk, turning raw sensor feeds into actionable intelligence that maritime security, defense, and law-enforcement organizations can act on quickly and reliably.

The Problem

Unmasking Dark Vessels with AI-Driven Maritime Surveillance

Organizations face these key challenges:

1

Missed detection of AIS-silent ('dark') vessels evading conventional monitoring

2

Delayed reporting and escalation due to manual video/image analysis

3

Operator overload from false positives and data deluge

4

Inability to correlate multi-source data (SAR, RF, AIS) for behavioral anomalies

Impact When Solved

Persistent wide-area maritime visibility, including dark vesselsHigher detection rates of illicit and covert activity with fewer false positivesScale surveillance coverage without linear increases in analysts or patrols

The Shift

Before AI~85% Manual

Human Does

  • Monitor AIS feeds and radar displays in real time and triage basic alerts based on rules or thresholds.
  • Manually review satellite and SAR imagery to visually identify ships and potential dark activity in priority areas.
  • Correlate vessel tracks, registry data, and intelligence reports to investigate suspicious behavior and identity inconsistencies.
  • Define and tune static rules, geofences, and watchlists to generate alerts for known patterns of concern.

Automation

  • Basic AIS aggregation, storage, and display in maritime traffic monitoring tools.
  • Static rule-based alerting (e.g., entering/exiting predefined zones, AIS turned off near a border).
  • Basic radar and imagery pre-processing (noise reduction, mapping to coordinates) with limited automation of object detection.
With AI~75% Automated

Human Does

  • Set mission priorities, risk policies, and feedback labels that guide AI models (e.g., what constitutes high-risk behavior).
  • Review and validate AI-ranked anomalies and investigate complex, ambiguous, or high-impact cases in depth.
  • Make operational decisions—tasking patrols, aircraft, or assets based on AI alerts and broader intelligence context.

AI Handles

  • Continuously ingest and fuse multi-sensor data (AIS, SAR, EO, RF, radar) into a unified, real-time maritime picture.
  • Automatically detect vessels in imagery and radar, including dark and non-cooperative ships, and associate them with tracks when possible.
  • Learn baseline patterns of normal maritime behavior and flag deviations such as dark activity, unusual loitering, rendezvous, route anomalies, and identity spoofing.
  • Score and prioritize anomalies by risk, filter out obvious false positives, and push only the most relevant alerts to analysts in near real time.

Quick Win

Cloud-Based AIS Outlier Alerts via Pre-Trained Anomaly Detection APIs

Typical Timeline:2-4 weeks

Leverages managed cloud APIs to ingest AIS tracks and surface-level movement data, automatically flagging vessels that deviate from known shipping lanes, exhibit speed anomalies, or show sudden course changes. Provides basic automated notifications to operators for further investigation.
