Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (NAVIGATOR ARIES and CRATOS) maintained close proximity (min 435m, avg 437m) for 90 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 English Channel Surveillance Zone, a known STS activity area.
