Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (MAERSK KAYA and ORIENTAL IXIA) maintained close proximity (min 436m, avg 438m) 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 Augusta, Sicily STS Zone, a known STS activity area.

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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (ORIENTAL IXIA and MAERSK KAYA) maintained close proximity (min 438m, avg 439m) for 201 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 Augusta, Sicily STS Zone, a known STS activity area.

Moderate-confidence STS candidate. Two tankers (MAERSK KAYA and ORIENTAL IXIA) maintained close proximity (min 437m, avg 439m) 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.

Confidence Analysis

Score: 60/100

Moderate-confidence STS candidate. Two tankers (ORIENTAL IXIA and MAERSK KAYA) maintained close proximity (min 437m, avg 439m) for 45 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (ORIENTAL IXIA and MAERSK KAYA) maintained close proximity (min 437m, avg 440m) for 108 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (MAERSK KAYA and MONTE ROSA) maintained close proximity (min 380m, avg 384m) for 150 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 60/100

Moderate-confidence STS candidate. Two tankers (ORIENTAL IXIA and MAERSK KAYA) maintained close proximity (min 437m, avg 440m) 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (MARETA and MAERSK KAYA) maintained close proximity (min 452m, avg 457m) for 99 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 Augusta, Sicily STS Zone, a known STS activity area.
