Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (HYPERION and ANDOVER) maintained close proximity (min 46m, avg 60m) for 38 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 ANDOVER) maintained close proximity (min 12m, avg 40m) for 62 minutes. 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: 80/100

High-confidence STS candidate. Two tankers (HIGH FREEDOM and ANDOVER) maintained close proximity (min 118m, avg 129m) for 85 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: 68/100

Moderate-confidence STS candidate. Two tankers (ANDOVER and KLEVER) maintained close proximity (min 48m, avg 129m) for 33 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.0 knots). Moderate distance variation observed during the encounter. Event occurred in Eastern Mediterranean Surveillance Zone, a known STS activity area.

Moderate-confidence STS candidate. Two tankers (BEAST and ANDOVER) maintained close proximity (min 6m, avg 30m) for 44 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.
