Confidence Analysis

Score: 87/100

High-confidence STS candidate. Two tankers (ROBA and TRITONEA) maintained close proximity (min 3m, avg 13m) for 180 minutes. Both vessels were slow-moving (avg speeds 1.0 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.

Confidence Analysis

Score: 77/100

Moderate-confidence STS candidate. Two tankers (ROBA and THALIA) maintained close proximity (min 5m, avg 11m) for 71 minutes. Both vessels were slow-moving (avg speeds 0.7 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.

Confidence Analysis

Score: 87/100

High-confidence STS candidate. Two tankers (ROBA and TRITONEA) maintained close proximity (min 8m, avg 18m) for 133 minutes. Both vessels were slow-moving (avg speeds 0.6 and 0.3 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.

Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (ROBA and ALBERTA) maintained close proximity (min 6m, avg 16m) for 161 minutes. Both vessels were slow-moving (avg speeds 0.5 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.

Confidence Analysis

Score: 74/100

Moderate-confidence STS candidate. Two tankers (THALIA and ROBA) maintained close proximity (min 99m, avg 125m) for 54 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.3 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Copenhagen Offshore Monitoring Zone, a known STS activity area.
