Confidence Analysis
Score: 75/100
Moderate-confidence STS candidate. Two tankers (SAMBA and PIERO A) maintained close proximity (min 2m, avg 11m) for 31 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 (PIERO A and SAMBA) maintained close proximity (min 2m, avg 5m) for 52 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.

Confidence Analysis
Score: 73/100
Moderate-confidence STS candidate. Two tankers (SEAGAS MAJOR and PIERO A) maintained close proximity (min 0m, avg 30m) for 50 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.

Confidence Analysis
Score: 75/100
Moderate-confidence STS candidate. Two tankers (ALMOND and PIERO A) maintained close proximity (min 3m, avg 4m) for 31 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.

"summary": "High-confidence STS candidate. Two tankers (THALIA and PIERO A) maintained close proximity (min 0m, avg 2m) for 66 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."
