Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (SAMBA and GEORGY MASLOV) maintained close proximity (min 3m, avg 15m) for 34 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: 82/100

High-confidence STS candidate. Two tankers (HYPERION and GEORGY MASLOV) maintained close proximity (min 5m, avg 11m) for 66 minutes. Both vessels were slow-moving (avg speeds 0.2 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 (TRANS FJORD and GEORGY MASLOV) maintained close proximity (min 3m, avg 6m) for 86 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.8 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.

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."
