Confidence Analysis

Score: 87/100

High-confidence STS candidate. Two tankers (MESTRAL and TRITONEA) maintained close proximity (min 41m, avg 75m) for 330 minutes. Both vessels were slow-moving (avg speeds 1.3 and 1.4 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Gulf of Oman Sanctioned Vessel Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (MESTRAL and TRITONEA) maintained close proximity (min 40m, avg 64m) for 351 minutes. Both vessels were slow-moving (avg speeds 1.0 and 1.1 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Gulf of Oman Sanctioned Vessel Monitoring Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (MESTRAL and TRITONEA) maintained close proximity (min 40m, avg 63m) for 374 minutes. Both vessels were slow-moving (avg speeds 1.2 and 1.3 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Gulf of Oman Sanctioned Vessel Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (ROCK N ROLL and MESTRAL) maintained close proximity (min 0m, avg 1m) for 191 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 Eastern Mediterranean Surveillance Zone, a known STS activity area.
