Confidence Analysis

Score: 72/100

Moderate-confidence STS candidate. Two tankers (SPRING FORTUNE and GAZ SERENITY) maintained close proximity (min 37m, avg 127m) for 38 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 Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 74/100

Moderate-confidence STS candidate. Two tankers (SPRING FORTUNE and GAZ SERENITY) maintained close proximity (min 37m, avg 124m) for 55 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 76/100

Moderate-confidence STS candidate. Two tankers (TRANS FJORD and SPRING FORTUNE) maintained close proximity (min 37m, avg 132m) for 71 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.4 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 76/100

Moderate-confidence STS candidate. Two tankers (THALIA and SPRING FORTUNE) maintained close proximity (min 36m, avg 127m) for 77 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.4 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Surveillance Zone, a known STS activity area.
