Confidence Analysis
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.

Confidence Analysis
High-confidence STS candidate. Two tankers (KALYMNOS DAWN and KRITI SAMARIA) maintained close proximity (min 68m, avg 79m) for 147 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
High-confidence STS candidate. Two tankers (KRITI SAMARIA and KALYMNOS DAWN) maintained close proximity (min 68m, avg 78m) for 318 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
High-confidence STS candidate. Two tankers (KALYMNOS DAWN and KRITI SAMARIA) maintained close proximity (min 73m, avg 105m) for 259 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.0 knots). Moderate distance variation observed during the encounter. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
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.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (STI HACKNEY and KRITI SAMARIA) maintained close proximity (min 380m, avg 441m) for 202 minutes. 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
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
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
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
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
Moderate-confidence STS candidate. Two tankers (KRITI SAMARIA and STI HACKNEY) maintained close proximity (min 446m, avg 449m) for 138 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.
