Confidence Analysis

Score: 51/100

Low-confidence STS candidate - may warrant review. Two tankers (SRIWANGI III and FAIR STAR) maintained close proximity (min 306m, avg 326m) for 41 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.2 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (SRIWANGI III and FAIR STAR) maintained close proximity (min 305m, avg 312m) for 70 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 Eastern Mediterranean Sanctions Monitoring Zone, a known STS activity area.

Moderate-confidence STS candidate. Two tankers (SRIWANGI III and FAIR STAR) maintained close proximity (min 305m, avg 312m) for 85 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 Eastern Mediterranean Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (SRIWANGI III and FAIR STAR) maintained close proximity (min 303m, avg 312m) for 244 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 Eastern Mediterranean Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 89/100

High-confidence STS candidate. Two tankers (WECO MADELEINE and FAIR STAR) maintained close proximity (min 78m, avg 91m) for 369 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 Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (EASTERLY JUPITER and FAIR STAR) maintained close proximity (min 297m, avg 301m) for 88 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 Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and FAIR STAR) maintained close proximity (min 297m, avg 301m) for 208 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 Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and FAIR STAR) maintained close proximity (min 297m, avg 301m) for 328 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 Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and FAIR STAR) maintained close proximity (min 297m, avg 301m) for 394 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 Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and FAIR STAR) maintained close proximity (min 295m, avg 300m) for 390 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 Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and FAIR STAR) maintained close proximity (min 298m, avg 301m) for 393 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 Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and FAIR STAR) maintained close proximity (min 290m, avg 301m) for 383 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 Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and FAIR STAR) maintained close proximity (min 290m, avg 301m) for 393 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 Sanctions Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and FAIR STAR) maintained close proximity (min 290m, avg 301m) for 392 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 Sanctions Monitoring Zone, a known STS activity area.
