Confidence Analysis

Score: 61/100

Moderate-confidence STS candidate. Two tankers (STI HACKNEY and KRITI SAMARIA) maintained close proximity (min 380m, avg 437m) for 76 minutes. Both vessels were slow-moving (avg speeds 0.3 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.

Both vessels were slow-moving (avg speeds 0.2 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: 60/100

Moderate-confidence STS candidate. Two tankers (STI HACKNEY and KRITI SAMARIA) maintained close proximity (min 452m, avg 455m) for 48 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 (STI HACKNEY and KRITI SAMARIA) maintained close proximity (min 449m, avg 454m) for 132 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 (STI HACKNEY and KRITI SAMARIA) maintained close proximity (min 446m, avg 448m) for 216 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: 65/100

Moderate-confidence STS candidate. Two tankers (KRITI SAMARIA and STI HACKNEY) maintained close proximity (min 446m, avg 449m) for 63 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: 65/100

Moderate-confidence STS candidate. Two tankers (STI HACKNEY and KRITI SAMARIA) maintained close proximity (min 448m, avg 451m) for 75 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: 65/100

Moderate-confidence STS candidate. Two tankers (STI HACKNEY and KRITI SAMARIA) maintained close proximity (min 446m, avg 448m) 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: 70/100

Moderate-confidence STS candidate. Two tankers (KRITI SAMARIA and STI HACKNEY) maintained close proximity (min 446m, avg 449m) for 105 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: 65/100

Moderate-confidence STS candidate. Two tankers (STI HACKNEY and KRITI SAMARIA) maintained close proximity (min 450m, avg 452m) for 63 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.
