Confidence Analysis

Score: 55/100

Low-confidence STS candidate – may warrant review. Two tankers (INTEGRATOR and NAVIGER 5) maintained close proximity (min 411m, avg 419m) for 38 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: 60/100

Moderate-confidence STS candidate. Two tankers (INTEGRATOR and NAVIGER 5) maintained close proximity (min 358m, avg 369m) for 30 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.

High-confidence STS candidate. Two tankers (NAVIGER 5 and INTEGRATOR) maintained close proximity (min 360m, avg 395m) for 384 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.

Score: 77/100

Moderate-confidence STS candidate. Two tankers (NAVIGER 5 and INTEGRATOR) maintained close proximity (min 360m, avg 408m) for 315 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.
