Confidence Analysis

Score: 49/100

Low-confidence STS candidate – may warrant review. Two tankers (FLINT WIND and TWERK) maintained close proximity (min 334m, avg 390m) for 32 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.7 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: 57/100

Low-confidence STS candidate – may warrant review. Two tankers (TWERK and FLINT WIND) maintained close proximity (min 334m, avg 391m) for 66 minutes. Both vessels were slow-moving (avg speeds 0.5 and 0.1 knots). Moderate distance variation observed during the encounter. Event occurred in Black Sea Sanctioned Vessel Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (TWERK and FLINT WIND) maintained close proximity (min 234m, avg 348m) for 147 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.1 knots). Moderate distance variation observed during the encounter. Event occurred in Black Sea Sanctioned Vessel Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 78/100

Moderate-confidence STS candidate. Two tankers (TWERK and FLINT WIND) maintained close proximity (min 234m, avg 346m) for 186 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 knots). Moderate distance variation observed during the encounter. Event occurred in Black Sea Sanctioned Vessel Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 58/100

Low-confidence STS candidate – may warrant review. Two tankers (FLINT WIND and TWERK) maintained close proximity (min 320m, avg 400m) for 46 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.1 knots). Moderate distance variation observed during the encounter. Event occurred in Black Sea Sanctioned Vessel Monitoring Zone, a known STS activity area.
