Confidence Analysis

Score: 84/100

High-confidence STS candidate. Two tankers (KILBURN and TSUBAKI) maintained close proximity (min 10m, avg 68m) for 175 minutes. Both vessels were slow-moving (avg speeds 1.8 and 1.8 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Sanctions Monitoring Zone, a known STS activity area.
