Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (NISSOS SIFNOS and STRIZH) maintained close proximity (min 1m, avg 1m) for 31 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.

Moderate-confidence STS candidate. Two tankers (NISSOS SIFNOS and ARINA) maintained close proximity (min 1m, avg 2m) for 31 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

Score: 75/100

Moderate-confidence STS candidate. Two tankers (OCEAN THALIA and NISSOS SIFNOS) maintained close proximity (min 0m, avg 1m) for 31 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

Score: 85/100

High-confidence STS candidate. Two tankers (NISSOS SIFNOS and STRIZH) maintained close proximity (min 0m, avg 2m) for 75 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.
