Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (ROSE I and ZONDAR) maintained close proximity (min 51m, avg 54m) for 54 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (ROSE I and ZONDAR) maintained close proximity (min 55m, avg 58m) for 246 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (ROSE I and ZONDAR) maintained close proximity (min 55m, avg 58m) for 282 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (ROSE I and ZONDAR) maintained close proximity (min 56m, avg 59m) for 351 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (ZONDAR and ROSE I) maintained close proximity (min 54m, avg 57m) for 54 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (ROSE I and ZONDAR) maintained close proximity (min 54m, avg 57m) for 75 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (ROSE I and ZONDAR) maintained close proximity (min 54m, avg 56m) for 120 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 Northern Baltic Sea Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (HISTRIA ATLAS and ROSE I) maintained close proximity (min 312m, avg 312m) for 54 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.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (VENTUS MARIA and ROSE I) maintained close proximity (min 0m, avg 2m) for 32 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 Central Mediterranean Surveillance Zone, a known STS activity area.
