Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (STI SOLACE and OSLO STAR) maintained close proximity (min 34m, avg 38m) for 30 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 Atlantic Midway Monitoring Zone, a known STS activity area.

Moderate-confidence STS candidate. Two tankers (STI SOLACE and OSLO STAR) maintained close proximity (min 27m, avg 33m) for 41 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 Atlantic Midway Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (STI SOLACE and OSLO STAR) maintained close proximity (min 27m, avg 37m) for 132 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 Atlantic Midway Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (STI SOLACE and OSLO STAR) maintained close proximity (min 21m, avg 36m) for 82 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 Atlantic Midway Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (STI SOLACE and OSLO STAR) maintained close proximity (min 34m, avg 37m) for 47 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 Atlantic Midway Monitoring Zone, a known STS activity area.
