Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (ETHERA and CRATOS) maintained close proximity (min 134m, avg 138m) for 69 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 Archipelago Sea Sanction Zone, a known STS activity area.

Confidence Analysis

Score: 77/100

Moderate-confidence STS candidate. Two tankers (CRATOS and ETHERA) maintained close proximity (min 134m, avg 157m) for 210 minutes. Both vessels were slow-moving (avg speeds 0.3 and 0.0 knots). Moderate distance variation observed during the encounter. Event occurred in Archipelago Sea Sanction Zone, a known STS activity area.

Confidence Analysis

Score: 81/100

High-confidence STS candidate. Two tankers (CRATOS and ETHERA) maintained close proximity (min 132m, avg 154m) for 258 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 Archipelago Sea Sanction Zone, a known STS activity area.

Confidence Analysis

Score: 81/100

High-confidence STS candidate. Two tankers (CRATOS and ETHERA) maintained close proximity (min 132m, avg 149m) for 336 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 Archipelago Sea Sanction Zone, a known STS activity area.

Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (CRATOS and ETHERA) maintained close proximity (min 132m, avg 137m) for 375 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 Archipelago Sea Sanction Zone, a known STS activity area.

Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (CRATOS and ETHERA) maintained close proximity (min 131m, avg 137m) for 384 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 Archipelago Sea Sanction Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (CRATOS and ETHERA) maintained close proximity (min 131m, avg 137m) for 360 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 Archipelago Sea Sanction Zone, a known STS activity area.
