Confidence Analysis

Score: 67/100

Moderate-confidence STS candidate. Two tankers (STI FULHAM and TWINKLE STAR) maintained close proximity (min 319m, avg 323m) for 80 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (STI FULHAM and TWINKLE STAR) maintained close proximity (min 316m, avg 320m) for 230 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Northern Baltic Sea Surveillance Zone, a known STS activity area.
