Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (OSAR and TRITONEA) maintained close proximity (min 2m, avg 5m) for 89 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

Score: 90/100

High-confidence STS candidate. Two tankers (OSAR and THALIA) maintained close proximity (min 0m, avg 2m) for 91 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.
