Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (SAMBA and ASTROLIGHT) maintained close proximity (min 3m, avg 12m) for 31 minutes. Both vessels were slow-moving (avg speeds 0.1 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 (ANHONA and ASTROLIGHT) maintained close proximity (min 1m, avg 2m) for 40 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: 80/100

High-confidence STS candidate. Two tankers (SAMBA and ASTROLIGHT) maintained close proximity (min 3m, avg 10m) for 54 minutes. Both vessels were slow-moving (avg speeds 0.1 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 (JASPER and ASTROLIGHT) maintained close proximity (min 1m, avg 12m) for 43 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: 72/100

Moderate-confidence STS candidate. Two tankers (ASTROLIGHT and GEORGY MASLOV) maintained close proximity (min 1m, avg 5m) for 38 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.3 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: 77/100

Moderate-confidence STS candidate. Two tankers (THALIA and ASTROLIGHT) maintained close proximity (min 0m, avg 1m) for 59 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.2 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: 87/100

High-confidence STS candidate. Two tankers (ILAN and ASTROLIGHT) maintained close proximity (min 0m, avg 4m) for 91 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 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: 66/100

Moderate-confidence STS candidate. Two tankers (ASTROLIGHT and NISSOS ANTIMILOS) maintained close proximity (min 1m, avg 18m) for 38 minutes. Both vessels were slow-moving (avg speeds 0.3 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 (ASTROLIGHT and HIGH FREEDOM) maintained close proximity (min 0m, avg 1m) for 34 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.
