Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (KAROL WOJTYLA and GULF PETROLEUM 4) maintained close proximity (min 454m, avg 456m) for 105 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 (RIKER and KAROL WOJTYLA) maintained close proximity (min 476m, avg 477m) for 51 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: 65/100

Moderate-confidence STS candidate. Two tankers (GULF PETROLEUM 4 and KAROL WOJTYLA) maintained close proximity (min 456m, avg 457m) for 72 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.
