Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (DIDIMON and DH BLOSSOMING) maintained close proximity (min 464m, avg 470m) for 102 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 DIDIMON) maintained close proximity (min 464m, avg 470m) for 156 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 (DIDIMON and DH BLOSSOMING) maintained close proximity (min 466m, avg 469m) for 69 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 DIDIMON) maintained close proximity (min 466m, avg 469m) for 135 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 (DIDIMON and DH BLOSSOMING) maintained close proximity (min 466m, avg 470m) for 243 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: 60/100

Moderate-confidence STS candidate. Two tankers (DIDIMON and DH BLOSSOMING) maintained close proximity (min 466m, avg 469m) for 51 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 (DIDIMON and DH BLOSSOMING) maintained close proximity (min 465m, avg 469m) for 294 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.

Minimum Distance: 465 meters
Average Distance: 469 meters
Duration: 5h 51m
Period: 2026-09-05T14:07:20+00:00 to 2026-09-05T19:58:20+00:00
Vessel A Avg Speed: 0.0 knots
Vessel B Avg Speed: 0.0 knots

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (DIDIMON and DH BLOSSOMING) maintained close proximity (min 465m, avg 469m) 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 Augusta, Sicily STS Zone, a known STS activity area.
