Confidence Analysis

Score: 83/100

High-confidence STS candidate. Two tankers (CHALLENGER and BW YUSHI) maintained close proximity (min 1m, avg 37m) for 76 minutes. Both vessels were slow-moving (avg speeds 0.6 and 0.6 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: 92/100

High-confidence STS candidate. Two tankers (CHALLENGER and BW YUSHI) maintained close proximity (min 1m, avg 46m) for 151 minutes. Both vessels were slow-moving (avg speeds 0.5 and 0.5 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.

High-confidence STS candidate. Two tankers (BW YUSHI and CHALLENGER) maintained close proximity (min 28m, avg 48m) for 88 minutes. Both vessels were slow-moving (avg speeds 0.7 and 0.7 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: 90/100

High-confidence STS candidate. Two tankers (CHALLENGER and BW YUSHI) maintained close proximity (min 2m, avg 58m) for 257 minutes. Both vessels were slow-moving (avg speeds 0.7 and 0.8 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.
