Confidence Analysis

Score: 72/100

Moderate-confidence STS candidate. Two tankers (SINO STAR and ANHONA) maintained close proximity (min 0m, avg 11m) for 35 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.1 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 (SAMBA and SINO STAR) maintained close proximity (min 3m, avg 14m) for 42 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.2 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 (ASTROLIGHT and SINO STAR) maintained close proximity (min 0m, avg 11m) for 36 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.2 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.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (AKAR WEST and SINO STAR) maintained close proximity (min 7m, avg 8m) for 156 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.
