Vessel A: IMO 9411989 (REGUETON) Liberia

Vessel B: IMO 8727939 (NAVIGER 5) RUSSIA

Minimum Distance: 489 meters
Average Distance: 494 meters
Duration: 30 minutes
Period: 2026-09-06T09:01:58+00:00 to 2026-09-06T09:32:04+00:00
Vessel A Avg Speed: 0.0 knots
Vessel B Avg Speed: 0.0 knots
Zone: Bosphorus/Dardanelles Approach

Confidence Analysis

Score: 55/100

Low-confidence STS candidate - may warrant review. Two tankers (REGUETON and NAVIGER 5) maintained close proximity (min 489m, avg 494m) for 30 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 Bosphorus/Dardanelles Approach, a known STS activity area.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (REGUETON and NAVIGER 5) maintained close proximity (min 471m, avg 486m) for 90 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 Bosphorus/Dardanelles Approach, a known STS activity area.

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 Black Sea Sanctioned Vessel Monitoring Zone, a known STS activity area."
