Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (KAPITAN DZHUMANOV and RYAZAN) maintained close proximity (min 281m, avg 285m) for 181 minutes. Both vessels were slow-moving (avg speeds 0.0 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.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (KAPITAN DZHUMANOV and RYAZAN) maintained close proximity (min 276m, avg 283m) for 58 minutes. Both vessels were slow-moving (avg speeds 0.0 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.
