Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (SOLSTRAUM and KORD ARCTIC) maintained close proximity (min 52m, avg 53m) for 30 minutes. Both vessels were slow-moving (avg speeds 0.1 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.
