Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (GELOR and NORDIC ZENITH) maintained close proximity (min 485m, avg 486m) for 60 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.3 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Bosphorus/Dardanelles Approach, a known STS activity area.
