Vessel A Avg Speed: 0.1 knots
Vessel B Avg Speed: 0.0 knots
Zone: Gulf of Oman Sanctioned Vessel Monitoring Zone

Confidence Analysis

Score: 55/100

Low-confidence STS candidate - may warrant review. Two tankers (LADY YASSO and DAISY) maintained close proximity (min 471m, avg 481m) for 39 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 Gulf of Oman Sanctioned Vessel Monitoring Zone, a known STS activity area.

Vessel A Avg Speed: 0.0 knots
Vessel B Avg Speed: 0.0 knots
Zone: Gulf of Oman Sanctioned Vessel Monitoring Zone

Confidence Analysis

Score: 55/100

Low-confidence STS candidate - may warrant review. Two tankers (LADY YASSO and DAISY) maintained close proximity (min 468m, avg 477m) for 30 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 Gulf of Oman Sanctioned Vessel Monitoring Zone, a known STS activity area.

Low-confidence STS candidate - may warrant review. Two tankers (LADY YASSO and DAISY) maintained close proximity (min 455m, avg 469m) for 36 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.

Confidence Analysis

Score: 65/100

Moderate-confidence STS candidate. Two tankers (LADY YASSO and DAISY) maintained close proximity (min 468m, avg 474m) for 87 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 Gulf of Oman Sanctioned Vessel Monitoring Zone, a known STS activity area.

Confidence Analysis

Score: 75/100

Moderate-confidence STS candidate. Two tankers (LADY YASSO and DAISY) maintained close proximity (min 463m, avg 473m) for 129 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 Gulf of Oman Sanctioned Vessel Monitoring Zone, a known STS activity area.

Vessel B Avg Speed: 0.0 knots
Zone: Gulf of Oman Sanctioned Vessel Monitoring Zone

Confidence Analysis

Score: 60/100

Moderate-confidence STS candidate. Two tankers (LADY YASSO and DAISY) maintained close proximity (min 466m, avg 474m) for 54 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 Gulf of Oman Sanctioned Vessel Monitoring Zone, a known STS activity area.
