Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (DIDIMON and BLUE ROSE) maintained close proximity (min 0m, avg 1m) for 149 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.

Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (THALIA and BLUE ROSE) maintained close proximity (min 2m, avg 2m) for 103 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.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (BLUE ROSE and MILANO) maintained close proximity (min 4m, avg 9m) for 32 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.1 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: 75/100

Moderate-confidence STS candidate. Two tankers (TRANS FJORD and BLUE ROSE) maintained close proximity (min 1m, avg 3m) for 33 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.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (BLUE ROSE and PERSEAS) maintained close proximity (min 2m, avg 6m) for 34 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.

High-confidence STS candidate. Two tankers (BLUE ROSE and MUMBAI) maintained close proximity (min 0m, avg 9m) for 52 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.1 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: 72/100

Moderate-confidence STS candidate. Two tankers (DENVER and BLUE ROSE) maintained close proximity (min 1m, avg 30m) 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 Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (SEAGAS MAJOR and BLUE ROSE) maintained close proximity (min 0m, avg 4m) for 51 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 Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (BLUE ROSE and ANHONA) maintained close proximity (min 1m, avg 9m) for 36 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.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (BLUE ROSE and AVELORA) maintained close proximity (min 41m, avg 68m) for 32 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.2 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.

Moderate-confidence STS candidate. Two tankers (BLUE ROSE and AVELORA) maintained close proximity (min 6m, avg 43m) for 33 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.3 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 (BLUE ROSE and AVELORA) maintained close proximity (min 6m, avg 49m) for 163 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 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.

Score: 95/100

High-confidence STS candidate. Two tankers (BLUE ROSE and AVELORA) maintained close proximity (min 6m, avg 49m) for 223 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.2 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 (AVELORA and BLUE ROSE) maintained close proximity (min 33m, avg 50m) for 384 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.2 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.

Both vessels were slow-moving (avg speeds 0.2 and 0.2 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."
