Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (DENVER and CHARIOT TIDE) maintained close proximity (min 30m, avg 35m) for 33 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 Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (DENVER and CHARIOT TIDE) maintained close proximity (min 24m, avg 33m) for 50 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 Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 87/100

High-confidence STS candidate. Two tankers (DENVER and CHARIOT TIDE) maintained close proximity (min 20m, avg 41m) for 100 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.2 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 87/100

High-confidence STS candidate. Two tankers (DENVER and CHARIOT TIDE) maintained close proximity (min 20m, avg 46m) for 316 minutes. Both vessels were slow-moving (avg speeds 0.6 and 0.6 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (CHARIOT TIDE and OPAL) maintained close proximity (min 51m, avg 55m) for 152 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 Monitoring Zone, a known STS activity area.
