Confidence Analysis

Score: 60/100

Moderate-confidence STS candidate. Two tankers (METIN HUSEYNOV and BERTOLLE) maintained close proximity (min 333m, avg 348m) for 39 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.1 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: 80/100

High-confidence STS candidate. Two tankers (METIN HUSEYNOV and BERTOLLE) maintained close proximity (min 333m, avg 362m) for 219 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.1 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: 80/100

High-confidence STS candidate. Two tankers (METIN HUSEYNOV and BERTOLLE) maintained close proximity (min 333m, avg 363m) for 294 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Bosphorus/Dardanelles Approach, a known STS activity area.
