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 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
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
Moderate-confidence STS candidate. Two tankers (KRITI SAMARIA and STI HACKNEY) maintained close proximity (min 446m, avg 450m) for 129 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.
