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.

High-confidence STS candidate. Two tankers (DIDIMON and ANDINO DELTA) maintained close proximity (min 47m, avg 66m) for 45 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: 95/100

High-confidence STS candidate. Two tankers (DIDIMON and ANDINO DELTA) maintained close proximity (min 47m, avg 67m) for 123 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.

High-confidence STS candidate. Two tankers (DIDIMON and ANDINO DELTA) maintained close proximity (min 47m, avg 68m) for 224 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.

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: 82/100

High-confidence STS candidate. Two tankers (ATMOS and DIDIMON) maintained close proximity (min 47m, avg 72m) for 81 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Surveillance Zone, a known STS activity area.
