Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (NAVIGATOR and DELPHI) maintained close proximity (min 397m, avg 398m) for 150 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: 80/100

High-confidence STS candidate. Two tankers (NAVIGATOR and DELPHI) maintained close proximity (min 395m, avg 398m) for 177 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: 80/100

High-confidence STS candidate. Two tankers (DELPHI and NAVIGATOR) maintained close proximity (min 396m, avg 399m) for 261 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: 80/100

High-confidence STS candidate. Two tankers (NAVIGATOR and DELPHI) maintained close proximity (min 395m, avg 398m) 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

Score: 75/100

Moderate-confidence STS candidate. Two tankers (DELPHI and NAVIGATOR) maintained close proximity (min 395m, avg 399m) 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.

Minimum Distance: 395 meters
Average Distance: 400 meters
Duration: 2h 27m
Period: 2026-10-24T22:10:51+00:00 to 2026-10-25T00:37:51+00:00

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (NAVIGATOR and DELPHI) maintained close proximity (min 395m, avg 400m) 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

Score: 70/100

Moderate-confidence STS candidate. Two tankers (DELPHI and NAVIGATOR) maintained close proximity (min 396m, avg 400m) for 78 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: 80/100

High-confidence STS candidate. Two tankers (NAVIGATOR and DELPHI) maintained close proximity (min 398m, avg 400m) for 252 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.

Moderate-confidence STS candidate. Two tankers (NAVIGATOR and DELPHI) maintained close proximity (min 396m, avg 399m) for 36 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: 80/100

High-confidence STS candidate. Two tankers (NAVIGATOR and DELPHI) maintained close proximity (min 395m, avg 397m) for 144 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.
