Confidence Analysis
Moderate-confidence STS candidate. Two tankers (THALIA and ARDMORE ENTERPRISE) maintained close proximity (min 1m, avg 24m) for 38 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 Unknown Maritime Surveillance Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (THALIA and CAMARO) maintained close proximity (min 0m, avg 3m) for 313 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 North Sea Surveillance Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (NISSOS TINOS and THALIA) maintained close proximity (min 2m, avg 25m) for 364 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 Central Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (THALIA and AMBELOS) maintained close proximity (min 0m, avg 4m) for 46 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 Eastern Mediterranean Surveillance Zone, a known STS activity area.

- Vessel B Avg Speed: 0.0 knots
- Zone: Eastern Mediterranean Surveillance Zone
Confidence Analysis
High-confidence STS candidate. Two tankers (THALIA and ATLAS) maintained close proximity (min 1m, avg 45m) 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 Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (THALIA and BLUE ROSE) maintained close proximity (min 1m, avg 1m) for 91 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 Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (THALIA and MILANO) maintained close proximity (min 1m, avg 27m) for 46 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.8 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Surveillance Zone, a known STS activity area.
