How the risk score works
14 weighted factors feed one number — open any one below to see exactly what it measures.
All 14 factors below are the complete set the scorer evaluates, and their weights sum to 100% of the composite risk score. Every vessel is scored against the same 14factors, in the same order, every time.
AIS Gap Detection
9.0%Measures the duration of a vessel's AIS gaps, with longer gaps contributing more risk.

Gap Frequency (90d)
9.0%Measures how many AIS gaps the vessel has recorded in the prior 90 days.
View methodology →
Location Risk
9.0%Weights proximity to known high-risk hotspots and the configured risk of those hotspots.
View methodology →
Flag State
9.0%Scores vessel flags associated with higher evasion or oversight risk.
View methodology →
Vessel Age
5.0%Scores older vessels according to the model's configured age thresholds.
View methodology →
Vessel Type
2.5%Applies the model's vessel-class signal, including its configured tanker weighting.
View methodology →
Prior History
5.0%Scores the vessel's prior AIS gap history as accumulated evidence.
View methodology →
Sanctions Match
9.0%Adds a binary signal when the vessel matches a sanctions record.
View methodology →
STS Transfer Detection
7.5%Scores confirmed, verified, and suspected ship-to-ship transfer evidence.
View methodology →
Draft Cargo Mismatch
7.5%Scores draft mismatches, directional anomalies, and high-deviation readings.
View methodology →
Vessel Loitering
7.5%Scores loitering events near vessels, hotspots, or outside routine port context.
View methodology →
Identity Change Tracking
7.5%Scores flag, name, and MMSI changes in a vessel's identity history.
View methodology →
P&I Insurance Coverage
7.5%Scores P&I coverage status and International Group membership evidence.
View methodology →
Obfuscation Risk
5.0%Scores entity-history signals such as renames, jurisdiction cycling, and address changes.
