Confidence Analysis

Score: 82/100

High-confidence STS candidate. Two tankers (ANDINO DELTA and DIDIMON) maintained close proximity (min 61m, avg 68m) for 78 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Southern Black Sea Sanctioned Vessel Zone, a known STS activity area.

Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (DIDIMON and ANDINO DELTA) maintained close proximity (min 47m, avg 67m) for 90 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 Southern Black Sea Sanctioned Vessel Zone, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (DIDIMON and ANDINO DELTA) maintained close proximity (min 61m, avg 69m) for 379 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 Southern Black Sea Sanctioned Vessel Zone, a known STS activity area.

Confidence Analysis

Score: 71/100

Moderate-confidence STS candidate. Two tankers (HIGH FREEDOM and ANDINO DELTA) maintained close proximity (min 69m, avg 87m) for 57 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Southern Black Sea Sanctioned Vessel Zone, a known STS activity area.
