Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (URSUS ARCTOS and URSUS MARITIMUS) maintained close proximity (min 13m, avg 43m) for 99 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Black Sea Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (URSUS ARCTOS and URSUS MARITIMUS) maintained close proximity (min 39m, avg 42m) for 33 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Black Sea Surveillance Zone, a known STS activity area.
