Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (KRITI CAPTAIN and STI COMANDANTE) maintained close proximity (min 296m, avg 299m) for 84 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 Southern Öresund Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (KRITI CAPTAIN and STI COMANDANTE) maintained close proximity (min 299m, avg 299m) for 42 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 Southern Öresund Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (STI COMANDANTE and KRITI CAPTAIN) maintained close proximity (min 292m, avg 297m) for 84 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 Southern Öresund Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (STI COMANDANTE and KRITI CAPTAIN) maintained close proximity (min 292m, avg 298m) for 114 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 Southern Öresund Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (KRITI CAPTAIN and STI COMANDANTE) maintained close proximity (min 292m, avg 298m) for 174 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 Southern Öresund Surveillance Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (KRITI CAPTAIN and STI COMANDANTE) maintained close proximity (min 296m, avg 298m) for 162 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 Southern Öresund Surveillance Zone, a known STS activity area.
