Sts🛰️? Sakhalin South Approach FLAGMAN (IMO: 8135215, MMSI: 273443820)

Sep 15, 2026 10:25 UTC 65/100 ▼

Vessel A: IMO 8135215 (FLAGMAN) Russia

Vessel B: IMO 8930744 (ZAPRAVSHCHIK 05) Russia

Minimum Distance: 260 meters
Average Distance: 264 meters
Duration: 34 minutes
Period: 2026-09-15T10:25:05+00:00 to 2026-09-15T10:59:19+00:00
Vessel A Avg Speed: 0.0 knots
Vessel B Avg Speed: 0.1 knots
Zone: Sakhalin South Approach

Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (FLAGMAN and ZAPRAVSHCHIK 05) maintained close proximity (min 260m, avg 264m) for 34 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 Sakhalin South Approach, a known STS activity area.

Vessel A Avg Speed: 0.0 knots
Vessel B Avg Speed: 0.0 knots
Zone: Ust-Luga/St. Petersburg Approach

Confidence Analysis

Score: 55/100

Low-confidence STS candidate – may warrant review. Two tankers (ODIN and FREYA) maintained close proximity (min 464m, avg 473m) for 36 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: 70/100

Moderate-confidence STS candidate. Two tankers (NOSTOS and MANTA BEYLERBEYI) maintained close proximity (min 421m, avg 449m) for 96 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 Black Sea Sanctioned Vessel Monitoring Zone, a known STS activity area.

Vessel A Avg Speed: 0.1 knots
Vessel B Avg Speed: 0.1 knots
Zone: Bosphorus/Dardanelles Approach

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (NOSTOS and MANTA BEYLERBEYI) maintained close proximity (min 421m, avg 449m) for 96 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 Bosphorus/Dardanelles Approach, a known STS activity area.

Moderate-confidence STS candidate. Two tankers (ORIS and RIST) maintained close proximity (min 2m, avg 29m) for 38 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.3 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Sakhalin South Approach, a known STS activity area.

Minimum Distance: 3 meters
Average Distance: 18 meters
Duration: 1h 11m
Period: 2026-09-15T08:24:27+00:00 to 2026-09-15T09:35:28+00:00
Vessel A Avg Speed: 0.2 knots
Vessel B Avg Speed: 0.0 knots
Zone: Sakhalin South Approach

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (PHOENIX II and OMSK) maintained close proximity (min 3m, avg 18m) for 71 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Sakhalin South Approach, a known STS activity area.
