Moderate-confidence STS candidate. Two tankers (NISSOS ANTIMILOS and SEAGAS MAJOR) maintained close proximity (min 0m, avg 24m) for 56 minutes. Both vessels were slow-moving (avg speeds 0.1 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.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (THALIA and SEAGAS MAJOR) maintained close proximity (min 2m, avg 2m) for 45 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.3 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
High-confidence STS candidate. Two tankers (ILAN and SEAGAS MAJOR) maintained close proximity (min 2m, avg 15m) for 193 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.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (SPRING FORTUNE and SEAGAS MAJOR) maintained close proximity (min 35m, avg 124m) for 38 minutes. Both vessels were slow-moving (avg speeds 0.2 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
High-confidence STS candidate. Two tankers (DENVER and SEAGAS MAJOR) maintained close proximity (min 1m, avg 5m) for 57 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.

- Zone: Eastern Mediterranean Surveillance Zone
Confidence Analysis
High-confidence STS candidate. Two tankers (TRANS FJORD and SEAGAS MAJOR) maintained close proximity (min 0m, avg 3m) for 59 minutes. Both vessels were slow-moving (avg speeds 0.0 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.

Confidence Analysis
High-confidence STS candidate. Two tankers (AHINOS and SEAGAS MAJOR) maintained close proximity (min 21m, avg 77m) for 193 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.3 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.
