Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (CHEM HELEN and RINA) maintained close proximity (min 2m, avg 2m) for 145 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 Unknown Maritime Surveillance Zone, a known STS activity area.
