Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (YARA J and SAMANYOLU) maintained close proximity (min 478m, avg 488m) for 60 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 Bosphorus/Dardanelles Approach, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (SAMANYOLU and YARA J) maintained close proximity (min 464m, avg 475m) for 275 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.
