Confidence Analysis

Score: 82/100

High-confidence STS candidate. Two tankers (ATMOS and DIDIMON) maintained close proximity (min 47m, avg 72m) for 81 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 Eastern Mediterranean Surveillance Zone, a known STS activity area.
