        "summary": "High-confidence STS candidate. Two tankers (ALFA SEA and VELOS AQUARIUS) maintained close proximity (min 67m, avg 76m) for 267 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."
