Confidence Analysis

Score: 72/100

Moderate-confidence STS candidate. Two tankers (TRANS FJORD and JASPER) maintained close proximity (min 1m, avg 26m) for 30 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.

Moderate-confidence STS candidate. Two tankers (JASPER and GAZ SERENITY) maintained close proximity (min 1m, avg 11m) for 43 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: 75/100

Moderate-confidence STS candidate. Two tankers (JASPER and TRANS FJORD) maintained close proximity (min 1m, avg 12m) for 43 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: 69/100

Moderate-confidence STS candidate. Two tankers (GEORGY MASLOV and JASPER) maintained close proximity (min 3m, avg 4m) for 42 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: 95/100

High-confidence STS candidate. Two tankers (AKAR WEST and JASPER) maintained close proximity (min 2m, avg 5m) for 164 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.

Moderate-confidence STS candidate. Two tankers (JASPER and SEAGAS MAJOR) maintained close proximity (min 1m, avg 13m) for 53 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.5 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 0.0 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."
