Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (YENISEI and TEWEST) maintained close proximity (min 34m, avg 42m) for 102 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.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (YENISEI and TEWEST) maintained close proximity (min 34m, avg 42m) for 216 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.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (SPHERE and YENISEI) maintained close proximity (min 34m, avg 36m) for 270 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.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (SPHERE and YENISEI) maintained close proximity (min 31m, avg 36m) for 337 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.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (SPHERE and YENISEI) maintained close proximity (min 33m, avg 37m) for 37 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.
