Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (TRANS FJORD and NISSOS ANTIMILOS) maintained close proximity (min 1m, avg 1m) 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.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (NISSOS ANTIMILOS and HIGH FREEDOM) maintained close proximity (min 1m, avg 7m) for 56 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

Score: 70/100

Moderate-confidence STS candidate. Two tankers (NISSOS ANTIMILOS and HYPERION) maintained close proximity (min 6m, avg 14m) for 43 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.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (NISSOS SERIFOS and NISSOS ANTIMILOS) maintained close proximity (min 0m, avg 2m) for 55 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.

Both vessels were slow-moving (avg speeds 0.2 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: 95/100

High-confidence STS candidate. Two tankers (NISSOS ANTIMILOS and TRANS FJORD) maintained close proximity (min 0m, avg 5m) for 228 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

Score: 80/100

High-confidence STS candidate. Two tankers (TRANS FJORD and NISSOS ANTIMILOS) maintained close proximity (min 1m, avg 3m) for 58 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

Score: 92/100

High-confidence STS candidate. Two tankers (NISSOS ANTIMILOS and SEAGAS MAJOR) maintained close proximity (min 0m, avg 2m) for 191 minutes. Both vessels were slow-moving (avg speeds 0.0 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.

High-confidence STS candidate. Two tankers (JASPER and NISSOS ANTIMILOS) maintained close proximity (min 1m, avg 1m) for 53 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 (NISSOS ANTIMILOS and GAZ SERENITY) maintained close proximity (min 0m, avg 4m) for 37 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 (NISSOS ANTIMILOS and TRANS FJORD) maintained close proximity (min 0m, avg 4m) for 37 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.
