Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (NORELIA and IZOLA) maintained close proximity (min 56m, avg 59m) for 33 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.2 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.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (IZOLA and NORELIA) maintained close proximity (min 48m, avg 54m) for 150 minutes. Both vessels were slow-moving (avg speeds 0.2 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.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (IZOLA and NORELIA) maintained close proximity (min 43m, avg 53m) for 334 minutes. Both vessels were slow-moving (avg speeds 0.2 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.
