Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (CHEONGHAE3HO and KUK DONG 1 HO) maintained close proximity (min 40m, avg 48m) for 36 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 Strait of Gibraltar Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 89/100

High-confidence STS candidate. Two tankers (CHEONGHAE3HO and KUK DONG 1 HO) maintained close proximity (min 20m, avg 50m) for 180 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.1 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.

High-confidence STS candidate. Two tankers (KUK DONG 1 HO and SUNGJIN ACE) maintained close proximity (min 51m, avg 66m) for 71 minutes. Both vessels were slow-moving (avg speeds 0.1 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.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (SUNGJIN ACE and KUK DONG 1 HO) maintained close proximity (min 48m, avg 69m) for 71 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 Strait of Gibraltar Surveillance Zone, a known STS activity area.
