Confidence Analysis
Moderate-confidence STS candidate. Two tankers (E PIONEER and KASTOS I) maintained close proximity (min 26m, avg 35m) for 33 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 (E PIONEER and KASTOS I) maintained close proximity (min 25m, avg 60m) for 90 minutes. Both vessels were slow-moving (avg speeds 0.5 and 0.6 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.

High-confidence STS candidate. Two tankers (KASTOS I and E PIONEER) maintained close proximity (min 19m, avg 63m) for 227 minutes. Both vessels were slow-moving (avg speeds 0.5 and 0.5 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 (E PIONEER and KASTOS I) maintained close proximity (min 12m, avg 30m) for 163 minutes. Both vessels were slow-moving (avg speeds 0.3 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.
