Confidence Analysis

Score: 60/100

Moderate-confidence STS candidate. Two tankers (DH BLOSSOMING and ANKARA) maintained close proximity (min 487m, avg 491m) for 57 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: 52/100

Low-confidence STS candidate - may warrant review. Two tankers (ANKARA and DH BLOSSOMING) maintained close proximity (min 480m, avg 481m) for 35 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.2 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 (ANKARA and DH BLOSSOMING) maintained close proximity (min 478m, avg 481m) for 162 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.1 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 (ANKARA and DH BLOSSOMING) maintained close proximity (min 478m, avg 480m) 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 (DH BLOSSOMING and ANKARA) maintained close proximity (min 475m, avg 480m) for 360 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 (ANKARA and DH BLOSSOMING) maintained close proximity (min 475m, avg 479m) for 269 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: 55/100

Low-confidence STS candidate - may warrant review. Two tankers (DIDIMON and DH BLOSSOMING) maintained close proximity (min 464m, avg 469m) for 33 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.
