Confidence Analysis

Score: 72/100

Moderate-confidence STS candidate. Two tankers (SUPER G and JAXSON) maintained close proximity (min 49m, avg 63m) for 42 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.3 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 (SUPER G and JAXSON) maintained close proximity (min 48m, avg 59m) for 72 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: 80/100

High-confidence STS candidate. Two tankers (SUPER G and MULE) maintained close proximity (min 17m, avg 61m) for 69 minutes. Both vessels were slow-moving (avg speeds 0.9 and 1.0 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: 77/100

Moderate-confidence STS candidate. Two tankers (MAMMA MARIA and SUPER G) maintained close proximity (min 13m, avg 52m) for 68 minutes. Both vessels were slow-moving (avg speeds 1.4 and 1.4 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.
