ESTIMATED — implied speed = straight-line distance / dark hours. Actual route unknown. Reference: loaded VLCC ~12-14 kn, ballast ~15-16 kn, stationary <1 kn = possible STS or anchorage.

Loitering Events

Port State Control

No inspection data held. This is not a clean record — we currently hold no PSC inspections for any vessel. Do not read the absence of detentions here as evidence of none.

Check Paris MOU and USCG PSIX directly for this vessel.

Cargo Manifests

No manifest data held. Our upstream manifest source now blocks automated access, so this dataset is empty for every vessel — absence here says nothing about this ship's cargo history.

Data sources: EU MRV (EMSA), CII computed, Global Fishing Watch, GFW dark events. All records cryptographically attested on Polygon.

Data sources: U.S. Treasury (OFAC SDN), U.S. Energy Information Administration, European Maritime Safety Agency (EU MRV), U.S. Coast Guard (PSIX), Global Fishing Watch (GFW satellite AIS), AISStream.io. All data cryptographically attested on Polygon blockchain.
