Confidence Analysis
High-confidence STS candidate. Two tankers (TM HAI HA 568 and GARUDA) maintained close proximity (min 47m, avg 53m) for 234 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
High-confidence STS candidate. Two tankers (TM HAI HA 568 and GARUDA) maintained close proximity (min 42m, avg 49m) for 299 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
High-confidence STS candidate. Two tankers (GARUDA and TM HAI HA 568) maintained close proximity (min 50m, avg 52m) 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 Malacca Strait Surveillance Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (GARUDA and TM HAI HA 568) maintained close proximity (min 50m, avg 58m) for 138 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.
