Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (CLEAN IMPERIAL and AURORA) maintained close proximity (min 281m, avg 284m) 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 Ceuta/Gibraltar STS Zone, a known STS activity area.

Moderate-confidence STS candidate. Two tankers (AURORA and CLEAN IMPERIAL) maintained close proximity (min 273m, avg 287m) 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 Ceuta/Gibraltar STS Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (CLEAN IMPERIAL and AURORA) maintained close proximity (min 274m, avg 287m) for 312 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 Ceuta/Gibraltar STS Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (CLEAN IMPERIAL and AURORA) maintained close proximity (min 274m, avg 287m) for 351 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 Ceuta/Gibraltar STS Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (CLEAN IMPERIAL and AURORA) maintained close proximity (min 284m, avg 291m) for 312 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 Ceuta/Gibraltar STS Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (CLEAN IMPERIAL and AURORA) maintained close proximity (min 282m, avg 291m) for 369 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 Ceuta/Gibraltar STS Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (CLEAN IMPERIAL and AURORA) maintained close proximity (min 282m, avg 292m) for 201 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 Ceuta/Gibraltar STS Zone, a known STS activity area.
