Confidence Analysis
Moderate-confidence STS candidate. Two tankers (DANIA J and E PIONEER) maintained close proximity (min 2m, avg 3m) for 31 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.

High-confidence STS candidate. Two tankers (ALEXIA and DANIA J) maintained close proximity (min 0m, avg 1m) for 45 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.

"summary": "High-confidence STS candidate. Two tankers (DANIA J and THALIA) maintained close proximity (min 0m, avg 5m) for 99 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."
