Confidence Analysis

Score: 77/100

Moderate-confidence STS candidate. Two tankers (JAG PRANESH and ALFA SEA) maintained close proximity (min 2m, avg 6m) for 75 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.8 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.

Moderate-confidence STS candidate. Two tankers (ALFA SEA and WECO MADELEINE) maintained close proximity (min 340m, avg 350m) for 97 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Sanctions Monitoring Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (SRIWANGI III and ALFA SEA) maintained close proximity (min 54m, avg 64m) for 239 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 Mediterranean Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (SRIWANGI III and ALFA SEA) maintained close proximity (min 54m, avg 66m) for 233 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 Mediterranean Sanctions Monitoring Zone, a known STS activity area.
