Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (ARCTICA and SOLSTRAUM) maintained close proximity (min 318m, avg 321m) for 47 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.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (VOLGONEFT 128 and ARCTICA) maintained close proximity (min 80m, avg 86m) for 53 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: 80/100

High-confidence STS candidate. Two tankers (ARCTICA and SOLSTRAUM) maintained close proximity (min 311m, avg 320m) for 301 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.

High-confidence STS candidate. Two tankers (ARCTICA and SOLSTRAUM) maintained close proximity (min 308m, avg 310m) for 184 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.
