Minimum Distance: 74 meters

Vessel A Avg Speed: 0.1 knots
Vessel B Avg Speed: 0.2 knots
Zone: Sakhalin South Approach

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (AZOV and FLAGMAN) maintained close proximity (min 74m, avg 75m) for 35 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.2 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Sakhalin South Approach, a known STS activity area.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (STI COMANDANTE and CHEM GUARD) maintained close proximity (min 247m, avg 250m) for 48 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 Southern Öresund Surveillance Zone, a known STS activity area.

Moderate-confidence STS candidate. Two tankers (ZAPRAVSHCHIK 05 and FLAGMAN) maintained close proximity (min 292m, avg 293m) for 58 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 Sakhalin South Approach, a known STS activity area.

Vessel B: IMO 8135215 (FLAGMAN) Russia

Minimum Distance: 73 meters
Average Distance: 74 meters
Duration: 31 minutes
Period: 2026-10-28T09:25:57+00:00 to 2026-10-28T09:57:21+00:00
Vessel A Avg Speed: 0.1 knots
Vessel B Avg Speed: 0.2 knots
Zone: Sakhalin South Approach

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (AZOV and FLAGMAN) maintained close proximity (min 73m, avg 74m) for 31 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 Sakhalin South Approach, a known STS activity area.

Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (ZONDAR and STI DAMA) maintained close proximity (min 307m, avg 308m) for 51 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.

Moderate-confidence STS candidate. Two tankers (CHEM GUARD and STI COMANDANTE) maintained close proximity (min 249m, avg 250m) for 42 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 Southern Öresund Surveillance Zone, a known STS activity area.

Vessel B Avg Speed: 0.1 knots

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (FLAGMAN and AZOV) maintained close proximity (min 73m, avg 79m) for 132 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 Sakhalin South Approach, a known STS activity area.

Vessel A: IMO 8135215 (FLAGMAN) Russia

Vessel B: IMO 9084401 (AZOV) Russia

Minimum Distance: 73 meters
Average Distance: 79 meters
Duration: 2h 12m
Period: 2026-10-28T08:23:09+00:00 to 2026-10-28T10:35:10+00:00
Vessel A Avg Speed: 0.1 knots
Vessel B Avg Speed: 0.1 knots
Zone: Prigorodnoye/Sakhalin LNG

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (FLAGMAN and AZOV) maintained close proximity (min 73m, avg 79m) for 132 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 Prigorodnoye/Sakhalin LNG, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (KRITI CAPTAIN and STI COMANDANTE) maintained close proximity (min 297m, avg 300m) for 126 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 Southern Öresund Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (ROSE I and ZONDAR) maintained close proximity (min 54m, avg 58m) for 60 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.
