Confidence Analysis

Score: 73/100

Moderate-confidence STS candidate. Two tankers (OCEAN WAVE I and MAMMA MARIA) maintained close proximity (min 17m, avg 92m) for 82 minutes. Both vessels were slow-moving (avg speeds 0.7 and 0.8 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 (MAMMA MARIA and OCEAN WAVE I) maintained close proximity (min 7m, avg 60m) for 256 minutes. Both vessels were slow-moving (avg speeds 0.9 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.

Confidence Analysis

Score: 93/100

High-confidence STS candidate. Two tankers (MAMMA MARIA and OCEAN WAVE I) maintained close proximity (min 7m, avg 50m) for 313 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: 85/100

High-confidence STS candidate. Two tankers (OCEAN WAVE I and MULE) maintained close proximity (min 19m, avg 66m) for 97 minutes. Both vessels were slow-moving (avg speeds 0.8 and 0.9 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.
