Confidence Analysis
Moderate-confidence STS candidate. Two tankers (SAMBA and ASTROLIGHT) maintained close proximity (min 3m, avg 12m) for 31 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.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (DORIN and ASTROLIGHT) maintained close proximity (min 4m, avg 8m) for 38 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 Surveillance Zone, a known STS activity area.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (NISSOS ANTIMILOS and ASTROLIGHT) maintained close proximity (min 0m, avg 1m) for 68 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
Moderate-confidence STS candidate. Two tankers (ASTROLIGHT and NISSOS ANTIMILOS) maintained close proximity (min 1m, avg 18m) for 38 minutes. Both vessels were slow-moving (avg speeds 0.3 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.
