Zone: Bosphorus/Dardanelles Approach

Confidence Analysis

Score: 55/100

Low-confidence STS candidate - may warrant review. Two tankers (AVIVA and MONA) maintained close proximity (min 472m, avg 472m) for 35 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.

Vessel A: IMO 9125279 (NORMAN) TUVALU

Vessel B: IMO 9410131 (AVIVA) Marshall Is

Minimum Distance: 404 meters
Average Distance: 420 meters
Duration: 1h 3m
Period: 2026-07-07T16:25:09+00:00 to 2026-07-07T17:28:08+00:00
Vessel A Avg Speed: 0.1 knots
Vessel B Avg Speed: 0.0 knots
Zone: Bosphorus/Dardanelles Approach

Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (NORMAN and AVIVA) maintained close proximity (min 404m, avg 420m) for 63 minutes. Both vessels were slow-moving (avg speeds 0.1 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: 80/100

High-confidence STS candidate. Two tankers (AVIVA and NORMAN) maintained close proximity (min 383m, avg 431m) for 252 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.

Confidence Analysis

Score: 78/100

Moderate-confidence STS candidate. Two tankers (AVIVA and NORMAN) maintained close proximity (min 299m, avg 411m) for 332 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 knots). Moderate distance variation observed during the encounter. Event occurred in Bosphorus/Dardanelles Approach, a known STS activity area.

Low-confidence STS candidate - may warrant review. Two tankers (AVIVA and NORMAN) maintained close proximity (min 452m, avg 468m) for 36 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 (AVIVA and NORMAN) maintained close proximity (min 356m, avg 433m) for 131 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.
