Moderate-confidence STS candidate. Two tankers (RINA and ARDMORE ENTERPRISE) maintained close proximity (min 3m, avg 9m) for 36 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.2 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.

Moderate-confidence STS candidate. Two tankers (RINA and MAERSK KAYA) maintained close proximity (min 0m, avg 4m) for 36 minutes. Both vessels were slow-moving (avg speeds 0.0 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.

High-confidence STS candidate. Two tankers (RINA and GAZ HORIZON) maintained close proximity (min 0m, avg 1m) for 360 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Central Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (RINA and PHOENIX II) maintained close proximity (min 0m, avg 1m) for 345 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Central Mediterranean Surveillance Zone, a known STS activity area.
