Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (PASCO ODIN and BW YUSHI) maintained close proximity (min 41m, avg 51m) for 30 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 Malta/Hurd's Bank STS Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (PASCO ODIN and BW YUSHI) maintained close proximity (min 39m, avg 48m) for 77 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 Malta/Hurd's Bank STS Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (PASCO ODIN and BW YUSHI) maintained close proximity (min 39m, avg 48m) for 77 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 Gulf of Oman Sanctioned Vessel Monitoring Zone, a known STS activity area.

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.

Confidence Analysis

Score: 86/100

High-confidence STS candidate. Two tankers (CHALLENGER and BW YUSHI) maintained close proximity (min 25m, avg 72m) for 322 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.

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.
