        "summary": "High-confidence STS candidate. Two tankers (THALIA and ATLAS) maintained close proximity (min 0m, avg 19m) for 97 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."
