Confidence Analysis

Score: 72/100

Moderate-confidence STS candidate. Two tankers (TAHITI and KUKDONG3HO) maintained close proximity (min 36m, avg 63m) for 39 minutes. Both vessels were slow-moving (avg speeds 0.3 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.

        "summary": "Moderate-confidence STS candidate. Two tankers (TAHITI and KUKDONG3HO) maintained close proximity (min 36m, avg 63m) for 39 minutes. Both vessels were slow-moving (avg speeds 0.3 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."
