Detected Events (100)
- Minimum Distance: 0 meters
- Average Distance: 3 meters
- Duration: 41 minutes
- Period: 2026-06-03T14:22:15+00:00 to 2026-06-03T15:04:06+00:00
- Vessel A Avg Speed: 0.0 knots
- Vessel B Avg Speed: 0.1 knots
- Zone: Eastern Mediterranean Surveillance Zone
Confidence Analysis
Moderate-confidence STS candidate. Two tankers (SAMBA and NISSOS SERIFOS) maintained close proximity (min 0m, avg 3m) for 42 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 Surveillance Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (SAMBA and ANHONA) maintained close proximity (min 2m, avg 9m) for 54 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 Surveillance Zone, a known STS activity area.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (SAMBA and HORAE) maintained close proximity (min 5m, avg 56m) for 58 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.1 knots). Moderate distance variation observed during the encounter. Event occurred in Eastern Mediterranean Surveillance Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (PIERO A and SAMBA) maintained close proximity (min 2m, avg 5m) for 52 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 Surveillance Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (HYPERION and SAMBA) maintained close proximity (min 9m, avg 10m) for 66 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.

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.
