Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (PRAGUE and MULE) maintained close proximity (min 23m, avg 49m) for 152 minutes. Both vessels were slow-moving (avg speeds 1.0 and 1.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Southern Öresund Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (PRAGUE and NORTHERN OSPREY) maintained close proximity (min 21m, avg 24m) for 51 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 English Channel Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 84/100

High-confidence STS candidate. Two tankers (NORTHERN OSPREY and PRAGUE) maintained close proximity (min 21m, avg 47m) for 104 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in English Channel Surveillance Zone, a known STS activity area.
