Confidence Analysis

Score: 73/100

Moderate-confidence STS candidate. Two tankers (SILVER TIGER and LOVE) maintained close proximity (min 50m, avg 62m) for 37 minutes. Both vessels were slow-moving (avg speeds 0.7 and 0.7 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Northern Baltic Sea Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 90/100

High-confidence STS candidate. Two tankers (SILVER TIGER and LOVE) maintained close proximity (min 34m, avg 62m) for 324 minutes. Both vessels were slow-moving (avg speeds 0.9 and 0.8 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Northern Baltic Sea Surveillance Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (SILVER TIGER and LOVE) maintained close proximity (min 26m, avg 55m) for 366 minutes. Both vessels were slow-moving (avg speeds 0.8 and 0.7 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Northern Baltic Sea Surveillance Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (SILVER TIGER and LOVE) maintained close proximity (min 40m, avg 69m) for 387 minutes. Both vessels were slow-moving (avg speeds 0.8 and 0.8 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Northern Baltic Sea Surveillance Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (SILVER TIGER and LOVE) maintained close proximity (min 40m, avg 64m) for 391 minutes. Both vessels were slow-moving (avg speeds 0.7 and 0.7 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Northern Baltic Sea Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 87/100

High-confidence STS candidate. Two tankers (LOVE and SILVER TIGER) maintained close proximity (min 46m, avg 70m) for 343 minutes. Both vessels were slow-moving (avg speeds 0.7 and 0.8 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Northern Baltic Sea Surveillance Zone, a known STS activity area.
