Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (KORSAKOV and VANINO) maintained close proximity (min 14m, avg 14m) for 43 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 Terminal Complex, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (VANINO and KORSAKOV) maintained close proximity (min 14m, avg 14m) for 78 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 Terminal Complex, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (VANINO and KORSAKOV) maintained close proximity (min 13m, avg 15m) for 228 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 Terminal Complex, a known STS activity area.

Minimum Distance: 13 meters
Average Distance: 14 meters
Duration: 6h 6m
Period: 2026-10-23T07:31:06+00:00 to 2026-10-23T13:37:06+00:00
Vessel A Avg Speed: 0.0 knots
Vessel B Avg Speed: 0.0 knots
Zone: Ust-Luga Terminal Complex

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (VANINO and KORSAKOV) maintained close proximity (min 13m, avg 14m) for 366 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 Terminal Complex, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (VANINO and KORSAKOV) maintained close proximity (min 18m, avg 19m) for 75 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 Terminal Complex, a known STS activity area.

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 Terminal Complex, a known STS activity area."
