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.

Moderate-confidence STS candidate. Two tankers (NAVIGATOR and DELPHI) maintained close proximity (min 399m, avg 402m) for 84 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.

Sts🛰️? Augusta, Sicily STS Zone

Oct 25, 2026 01:22 UTC 80/100 ▼

Vessel A: IMO 9370719 (NAVIGATOR) Marshall Is

Vessel B: IMO 9283796 (DELPHI) Liberia

Minimum Distance: 395 meters
Average Distance: 398 meters
Duration: 5h 18m
Period: 2026-10-25T01:22:51+00:00 to 2026-10-25T06:40:51+00:00
Vessel A Avg Speed: 0.0 knots
Vessel B Avg Speed: 0.0 knots
Zone: Augusta, Sicily STS Zone

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: 70/100

Moderate-confidence STS candidate. Two tankers (NAVIGATOR and DELPHI) maintained close proximity (min 395m, avg 399m) for 87 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 400m) for 159 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 126 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.

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.

Confidence Analysis

Score: 60/100

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.
