Confidence Analysis
Low-confidence STS candidate - may warrant review. Two tankers (NAVIGER 5 and LYDIA KA) maintained close proximity (min 467m, avg 474m) for 39 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
Low-confidence STS candidate - may warrant review. Two tankers (INTEGRATOR and LYDIA KA) maintained close proximity (min 478m, avg 485m) for 39 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
Low-confidence STS candidate - may warrant review. Two tankers (LYDIA KA and NAVIGER 5) maintained close proximity (min 476m, avg 488m) for 33 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
Low-confidence STS candidate - may warrant review. Two tankers (LYDIA KA and NAVIGER 5) maintained close proximity (min 475m, avg 486m) for 42 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
Moderate-confidence STS candidate. Two tankers (NAVIGER 5 and LYDIA KA) maintained close proximity (min 420m, avg 447m) for 63 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
Moderate-confidence STS candidate. Two tankers (INTEGRATOR and LYDIA KA) maintained close proximity (min 444m, avg 461m) for 54 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
Moderate-confidence STS candidate. Two tankers (LYDIA KA and INTEGRATOR) maintained close proximity (min 430m, avg 463m) for 174 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
Low-confidence STS candidate - may warrant review. Two tankers (LYDIA KA and INTEGRATOR) maintained close proximity (min 479m, avg 488m) for 33 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
Moderate-confidence STS candidate. Two tankers (INTEGRATOR and LYDIA KA) maintained close proximity (min 258m, avg 275m) for 34 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
Low-confidence STS candidate - may warrant review. Two tankers (INTEGRATOR and LYDIA KA) maintained close proximity (min 336m, avg 380m) for 45 minutes. Both vessels were slow-moving (avg speeds 0.2 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.
