Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (RAS TOMB and RONG HUA WAN) maintained close proximity (min 324m, avg 329m) for 111 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Low-confidence STS candidate - may warrant review. Two tankers (WINTER SUN and RONG HUA WAN) maintained close proximity (min 436m, avg 467m) for 39 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (RONG HUA WAN and RAS TOMB) maintained close proximity (min 300m, avg 341m) for 93 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Moderate-confidence STS candidate. Two tankers (RONG HUA WAN and RAS TOMB) maintained close proximity (min 300m, avg 374m) for 201 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Event occurred in Augusta, Sicily STS Zone, a known STS activity area."
