Confidence Analysis

Score: 87/100

High-confidence STS candidate. Two tankers (RYAZAN and ABIGAIL) maintained close proximity (min 133m, avg 147m) for 289 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.0 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.
