  • Minimum Distance: 48 meters
  • Average Distance: 51 meters
  • Duration: 57 minutes
  • Period: 2026-06-06T13:02:06+00:00 to 2026-06-06T13:59:06+00:00

  • Zone: Eastern Mediterranean Monitoring Zone

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (DENVER and JASPER) maintained close proximity (min 48m, avg 51m) for 57 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 Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 85/100

High-confidence STS candidate. Two tankers (DENVER and JASPER) maintained close proximity (min 48m, avg 51m) for 81 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 Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 95/100

High-confidence STS candidate. Two tankers (DENVER and JASPER) maintained close proximity (min 46m, avg 50m) for 279 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 Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 72/100

Moderate-confidence STS candidate. Two tankers (MUMBAI and DENVER) maintained close proximity (min 0m, avg 9m) for 34 minutes. Both vessels were slow-moving (avg speeds 0.2 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (NEW LEGEND and DENVER) maintained close proximity (min 2m, avg 9m) for 40 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 Surveillance Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (GAZ HORIZON and DENVER) maintained close proximity (min 1m, avg 8m) for 131 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 Surveillance Zone, a known STS activity area.
