Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (HAWK III and ATLAS) maintained close proximity (min 82m, avg 113m) for 33 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 Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (HAWK III and ALEXIA) maintained close proximity (min 38m, avg 57m) for 74 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

Moderate-confidence STS candidate. Two tankers (HAWK III and ANGEL K) maintained close proximity (min 15m, avg 38m) for 30 minutes. Both vessels were slow-moving (avg speeds 0.0 and 1.3 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.

High-confidence STS candidate. Two tankers (THALIA and HAWK III) maintained close proximity (min 52m, avg 60m) for 123 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 Copenhagen Offshore Monitoring Zone, a known STS activity area.

Event occurred in Copenhagen Offshore Monitoring Zone, a known STS activity area."
