- Minimum Distance: 68 meters
- Average Distance: 155 meters
- Duration: 40 minutes
- Period: 2026-10-23T08:06:06+00:00 to 2026-10-23T08:46:08+00:00
- Vessel A Avg Speed: 0.1 knots
- Vessel B Avg Speed: 0.1 knots
- Zone: Sakhalin South Approach
Confidence Analysis
Moderate-confidence STS candidate. Two tankers (SOLARIS and BUKHTA NAGAEVA) maintained close proximity (min 68m, avg 155m) for 40 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
High-confidence STS candidate. Two tankers (BUKHTA NAGAEVA and SOLARIS) maintained close proximity (min 43m, avg 147m) for 259 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
High-confidence STS candidate. Two tankers (BUKHTA NAGAEVA and SOLARIS) maintained close proximity (min 43m, avg 159m) for 340 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 knots). Moderate distance variation observed during the encounter. Event occurred in Sakhalin South Approach, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (BUKHTA NAGAEVA and SOLARIS) maintained close proximity (min 43m, avg 167m) for 386 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.2 knots). Moderate distance variation observed during the encounter. Event occurred in Sakhalin South Approach, a known STS activity area.
