Confidence Analysis
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
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.

Confidence Analysis
High-confidence STS candidate. Two tankers (CHALLENGER and BW YUSHI) maintained close proximity (min 26m, avg 75m) for 296 minutes. Both vessels were slow-moving (avg speeds 0.9 and 0.9 knots). Moderate distance variation observed during the encounter. Event occurred in Southern Öresund Surveillance Zone, a known STS activity area.
