Confidence Analysis

Score: 55/100

Low-confidence STS candidate – may warrant review. Two tankers (SAMANYOLU and VELES) maintained close proximity (min 473m, avg 483m) for 39 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: 55/100

Low-confidence STS candidate – may warrant review. Two tankers (SAMANYOLU and VELES) maintained close proximity (min 460m, avg 481m) for 34 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.
