Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (OPAL and INDUS 1) maintained close proximity (min 20m, avg 50m) for 81 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 Sanctioned Vessel Zone, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (OPAL and INDUS 1) maintained close proximity (min 20m, avg 50m) for 258 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 Sanctioned Vessel Zone, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (OPAL and INDUS 1) maintained close proximity (min 20m, avg 51m) for 386 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 Sanctioned Vessel Zone, a known STS activity area.
