Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (HAVVA ANA and GAS LISBON) maintained close proximity (min 395m, avg 425m) for 81 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 (GAS LISBON and HAVVA ANA) maintained close proximity (min 429m, avg 439m) for 35 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.
