Confidence Analysis
Score: 90/100
High-confidence STS candidate. Two tankers (FRANK LIGHT and FORTUNA ONE) maintained close proximity (min 32m, avg 40m) for 93 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.

Confidence Analysis
Score: 95/100
High-confidence STS candidate. Two tankers (FRANK LIGHT and FORTUNA ONE) maintained close proximity (min 30m, avg 39m) for 174 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.
