Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (ALTURA and VELORA) maintained close proximity (min 39m, avg 48m) for 32 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 Bosphorus/Dardanelles Approach, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (VELORA and ALTURA) maintained close proximity (min 45m, avg 48m) for 122 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: 80/100

High-confidence STS candidate. Two tankers (ALTURA and VELORA) maintained close proximity (min 28m, avg 56m) for 58 minutes. Both vessels were slow-moving (avg speeds 0.2 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: 95/100

High-confidence STS candidate. Two tankers (VELORA and ALTURA) maintained close proximity (min 34m, avg 44m) for 207 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 Bosphorus/Dardanelles Approach, a known STS activity area.

High-confidence STS candidate. Two tankers (VELORA and ALTURA) maintained close proximity (min 34m, avg 46m) for 341 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 Bosphorus/Dardanelles Approach, a known STS activity area.
