Confidence Analysis
High-confidence STS candidate. Two tankers (PROMETEY and PIERO A) maintained close proximity (min 61m, avg 64m) for 90 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 Monitoring Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (PROMETEY and PIERO A) maintained close proximity (min 57m, avg 68m) for 222 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 Monitoring Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (URSUS ARCTOS and PIERO A) maintained close proximity (min 71m, avg 78m) for 96 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 Monitoring Zone, a known STS activity area.
