Confidence Analysis
Moderate-confidence STS candidate. Two tankers (SATURN A and COAST BUSTER) maintained close proximity (min 341m, avg 345m) for 38 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 Bosphorus/Dardanelles Approach, a known STS activity area.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (SATURN A and COAST BUSTER) maintained close proximity (min 341m, avg 392m) for 161 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 Bosphorus/Dardanelles Approach, a known STS activity area.

"summary": "Moderate-confidence STS candidate. Two tankers (SATURN A and COAST BUSTER) maintained close proximity (min 341m, avg 397m) for 227 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 Bosphorus\/Dardanelles Approach, a known STS activity area."

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (SATURN A and TRITONEA) maintained close proximity (min 18m, avg 25m) for 36 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.3 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (SATURN A and TRITONEA) maintained close proximity (min 11m, avg 48m) for 106 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.4 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Sanctions Monitoring Zone, a known STS activity area.
