Vessel A: IMO 8711760 (KAPITAN DZHUMANOV) Russia

Vessel B: IMO 9010931 (GALA) RUSSIA

Minimum Distance: 91 meters
Average Distance: 92 meters
Duration: 3h 8m
Period: 2026-09-23T07:05:11+00:00 to 2026-09-23T10:13:51+00:00
Vessel A Avg Speed: 0.0 knots
Vessel B Avg Speed: 0.0 knots
Zone: Ust-Luga/St. Petersburg Approach

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (KAPITAN DZHUMANOV and GALA) maintained close proximity (min 90m, avg 92m) for 189 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: 95/100

High-confidence STS candidate. Two tankers (KAPITAN DZHUMANOV and GALA) maintained close proximity (min 86m, avg 95m) for 252 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 Ust-Luga/St. Petersburg Approach, a known STS activity area.
