Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (OMSK and OKEAN) maintained close proximity (min 6m, avg 11m) for 54 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 Prigorodnoye/Sakhalin LNG, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (OKEAN and OMSK) maintained close proximity (min 6m, avg 10m) for 132 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 Prigorodnoye/Sakhalin LNG, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (OKEAN and OMSK) maintained close proximity (min 6m, avg 10m) for 159 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 Prigorodnoye/Sakhalin LNG, a known STS activity area.
