Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (PRAGUE and ECO STREAM) maintained close proximity (min 355m, avg 361m) for 48 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 Malacca Strait Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (PRAGUE and ECO STREAM) maintained close proximity (min 351m, avg 362m) for 129 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 Malacca Strait Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (PRAGUE and ECO STREAM) maintained close proximity (min 351m, avg 374m) for 258 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 Malacca Strait Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (SUPER G and ECO STREAM) maintained close proximity (min 454m, avg 464m) for 78 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 Malacca Strait Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (ECO STREAM and SUPER G) maintained close proximity (min 452m, avg 469m) for 60 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 Malacca Strait Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (PRAGUE and ECO STREAM) maintained close proximity (min 361m, avg 409m) for 266 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 Malacca Strait Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 60/100

Moderate-confidence STS candidate. Two tankers (ECO STREAM and PRAGUE) maintained close proximity (min 361m, avg 362m) 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 Malacca Strait Surveillance Zone, a known STS activity area.
