Confidence Analysis

Score: 60/100

Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 444m, avg 446m) 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.

Moderate-confidence STS candidate. Two tankers (STAVANGER STAR and GAS HUSKY) maintained close proximity (min 437m, avg 444m) for 297 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: 55/100

Low-confidence STS candidate - may warrant review. Two tankers (STAVANGER STAR and GAS HUSKY) maintained close proximity (min 439m, avg 443m) for 36 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.

Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 438m, avg 444m) 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 Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 440m, avg 443m) 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.

Confidence Analysis

Score: 70/100

Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 440m, avg 444m) for 96 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.

Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 439m, avg 441m) for 318 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: 55/100

Low-confidence STS candidate - may warrant review. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 443m, avg 443m) for 36 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.

Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 442m, avg 444m) for 288 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 (STAVANGER STAR and GAS HUSKY) maintained close proximity (min 443m, avg 455m) for 49 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 Augusta, Sicily STS Zone, a known STS activity area.
