Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (CROCO and PIERO A) maintained close proximity (min 40m, avg 43m) for 110 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 Black Sea Sanctioned Vessel Monitoring Zone, a known STS activity area.
