Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (DELPHI and KALYMNOS DAWN) maintained close proximity (min 398m, avg 401m) for 66 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (KALYMNOS DAWN and DELPHI) maintained close proximity (min 396m, avg 399m) for 60 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (KALYMNOS DAWN and DELPHI) maintained close proximity (min 396m, avg 402m) for 90 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (DELPHI and KALYMNOS DAWN) maintained close proximity (min 387m, avg 396m) for 66 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (KALYMNOS DAWN and DELPHI) maintained close proximity (min 394m, avg 400m) for 111 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 79/100

Moderate-confidence STS candidate. Two tankers (KALYMNOS DAWN and KRITI SAMARIA) maintained close proximity (min 75m, avg 93m) for 75 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.4 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.
