Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (JS SUN and KUM KANG) maintained close proximity (min 19m, avg 32m) for 59 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.2 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Strait of Gibraltar Surveillance Zone, a known STS activity area.
