Vessel A: IMO 9335915 (BLUE ROSE) MARSHALL ISLANDS

Vessel B: IMO 9326811 (PERSEAS) LIBERIA

Minimum Distance: 2 meters
Average Distance: 6 meters
Duration: 34 minutes
Period: 2026-06-05T16:13:30+00:00 to 2026-06-05T16:47:40+00:00
Vessel A Avg Speed: 0.0 knots
Vessel B Avg Speed: 0.0 knots
Zone: Eastern Mediterranean Surveillance Zone

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (BLUE ROSE and PERSEAS) maintained close proximity (min 2m, avg 6m) for 34 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.

Moderate-confidence STS candidate. Two tankers (PERSEAS and MUMBAI) maintained close proximity (min 2m, avg 8m) for 40 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.

Vessel A: IMO 9326811 (PERSEAS) LIBERIA

Vessel B: BOBCAT (BOBCAT) Oman

Minimum Distance: 4 meters
Average Distance: 8 meters
Duration: 39 minutes
Period: 2026-06-05T15:58:11+00:00 to 2026-06-05T16:37:41+00:00
Vessel A Avg Speed: 0.1 knots
Vessel B Avg Speed: 0.0 knots
Zone: Eastern Mediterranean Surveillance Zone

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (PERSEAS and BOBCAT) maintained close proximity (min 4m, avg 8m) for 40 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.

Confidence Analysis

Score: 80/100

High-confidence STS candidate. Two tankers (HYPERION and PERSEAS) maintained close proximity (min 2m, avg 36m) for 55 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.

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."
