Confidence Analysis

Score: 67/100

Moderate-confidence STS candidate. Two tankers (DORIN and HYPERION) maintained close proximity (min 9m, avg 17m) for 38 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.7 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 (HYPERION and THALIA) maintained close proximity (min 5m, avg 70m) for 66 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.0 knots). Moderate distance variation observed during the encounter. Event occurred in Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (DENVER and HYPERION) maintained close proximity (min 6m, avg 7m) for 80 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 (ILAN and HYPERION) maintained close proximity (min 2m, avg 4m) for 54 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.
