Confidence Analysis

Score: 87/100

High-confidence STS candidate. Two tankers (FAIR STAR and KOCATEPE) maintained close proximity (min 88m, avg 105m) for 91 minutes. Both vessels were slow-moving (avg speeds 0.3 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.

Moderate-confidence STS candidate. Two tankers (KOCATEPE and EASTERLY JUPITER) maintained close proximity (min 328m, avg 332m) for 60 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.5 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.

High-confidence STS candidate. Two tankers (KOCATEPE and FAIR STAR) maintained close proximity (min 85m, avg 92m) for 378 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 Eastern Mediterranean Sanctions Monitoring Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (KOCATEPE and EASTERLY JUPITER) maintained close proximity (min 326m, avg 330m) for 357 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: 95/100

High-confidence STS candidate. Two tankers (KOCATEPE and FAIR STAR) maintained close proximity (min 84m, avg 87m) for 384 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: 95/100

High-confidence STS candidate. Two tankers (KOCATEPE and FAIR STAR) maintained close proximity (min 84m, avg 87m) 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: 80/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and KOCATEPE) maintained close proximity (min 326m, avg 330m) 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: 95/100

High-confidence STS candidate. Two tankers (KOCATEPE and FAIR STAR) maintained close proximity (min 84m, avg 87m) for 387 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: 80/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and KOCATEPE) maintained close proximity (min 326m, avg 331m) 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.

High-confidence STS candidate. Two tankers (KOCATEPE and EASTERLY JUPITER) maintained close proximity (min 326m, avg 331m) 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.

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and KOCATEPE) maintained close proximity (min 326m, avg 331m) for 388 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: 80/100

High-confidence STS candidate. Two tankers (EASTERLY JUPITER and KOCATEPE) maintained close proximity (min 328m, avg 332m) for 378 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.
