Confidence Analysis

Score: 79/100

Moderate-confidence STS candidate. Two tankers (AHINOS and MILANO) maintained close proximity (min 78m, avg 148m) for 68 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.

Moderate-confidence STS candidate. Two tankers (AHINOS and DENVER) maintained close proximity (min 201m, avg 211m) for 72 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: 82/100

High-confidence STS candidate. Two tankers (AHINOS and SAMBA) maintained close proximity (min 55m, avg 119m) for 84 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: 82/100

High-confidence STS candidate. Two tankers (AHINOS and HYPERION) maintained close proximity (min 48m, avg 120m) for 86 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 (DORIN and AHINOS) maintained close proximity (min 116m, avg 140m) for 35 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: 72/100

Moderate-confidence STS candidate. Two tankers (MANTA and AHINOS) maintained close proximity (min 118m, avg 142m) for 48 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.2 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: 87/100

High-confidence STS candidate. Two tankers (AHINOS and DORIN) maintained close proximity (min 81m, avg 116m) for 104 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.

High-confidence STS candidate. Two tankers (THALIA and AHINOS) maintained close proximity (min 82m, avg 139m) for 122 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: 92/100

High-confidence STS candidate. Two tankers (AHINOS and SEAGAS MAJOR) maintained close proximity (min 21m, avg 77m) for 193 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.
