Prigorodnoye/Sakhalin LNG
Vessel A: IMO 9004310 (ORIS) TOGO
Vessel B: IMO 9449651 (RIST) TOGO
- Minimum Distance: 2 meters
- Average Distance: 29 meters
- Duration: 38 minutes
- Period: 2026-09-15T08:55:08+00:00 to 2026-09-15T09:33:18+00:00
- Vessel A Avg Speed: 0.2 knots
- Vessel B Avg Speed: 0.3 knots
- Zone: Prigorodnoye/Sakhalin LNG
Confidence Analysis
Score: 75/100
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 Prigorodnoye/Sakhalin LNG, a known STS activity area.
