Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (GAZ SERENITY and BEAST) maintained close proximity (min 26m, avg 52m) for 143 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: 80/100

High-confidence STS candidate. Two tankers (NISSOS ANTIMILOS and BEAST) maintained close proximity (min 74m, avg 105m) 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 Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 66/100

Moderate-confidence STS candidate. Two tankers (BEAST and NISSOS ANTIMILOS) maintained close proximity (min 1m, avg 41m) for 44 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: 66/100

Moderate-confidence STS candidate. Two tankers (BEAST and ATLAS) maintained close proximity (min 1m, avg 49m) for 41 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.4 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: 79/100

Moderate-confidence STS candidate. Two tankers (BEAST and TRANS FJORD) maintained close proximity (min 1m, avg 55m) for 72 minutes. Both vessels were slow-moving (avg speeds 0.2 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 (HIGH FREEDOM and BEAST) maintained close proximity (min 26m, avg 94m) for 36 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.
