Confidence Analysis

Score: 55/100

Low-confidence STS candidate - may warrant review. Two tankers (REGUETON and NAVIGER 5) maintained close proximity (min 441m, avg 468m) for 33 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 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: 55/100

Low-confidence STS candidate - may warrant review. Two tankers (REGUETON and NAVIGER 5) maintained close proximity (min 489m, avg 494m) for 30 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 Bosphorus/Dardanelles Approach, a known STS activity area.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (REGUETON and NAVIGER 5) maintained close proximity (min 471m, avg 486m) 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 Bosphorus/Dardanelles Approach, a known STS activity area.
