Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (RYAZAN and ABRAU) maintained close proximity (min 13m, avg 16m) for 134 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 Ust-Luga/St. Petersburg Approach, a known STS activity area.
