High-confidence STS candidate. Two tankers (KILBURN and TSUBAKI) maintained close proximity (min 10m, avg 68m) for 175 minutes. Both vessels were slow-moving (avg speeds 1.8 and 1.8 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: 74/100

Moderate-confidence STS candidate. Two tankers (KILBURN and PASCO STAR) maintained close proximity (min 46m, avg 77m) for 76 minutes. Both vessels were slow-moving (avg speeds 1.1 and 1.3 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: 84/100

High-confidence STS candidate. Two tankers (PASCO STAR and KILBURN) maintained close proximity (min 40m, avg 77m) for 235 minutes. Both vessels were slow-moving (avg speeds 1.4 and 1.2 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 (PASCO STAR and KILBURN) maintained close proximity (min 41m, avg 83m) for 194 minutes. Both vessels were slow-moving (avg speeds 0.9 and 0.6 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: 93/100

High-confidence STS candidate. Two tankers (KILBURN and PASCO STAR) maintained close proximity (min 36m, avg 56m) for 365 minutes. Both vessels were slow-moving (avg speeds 0.9 and 0.9 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.
