How it works
The ultimate beneficial owner (UBO) is the natural person or top-level company that genuinely owns or controls a ship, as opposed to the single-ship registered owner, the manager or the disponent owner that may appear in routine records. Shipping ownership is frequently layered through one-ship companies and holding structures.
Identifying the UBO is central to sanctions compliance and counterparty due diligence, since restrictions attach to the controlling party, not just the name on the registry. We build owner-to-parent links from public corporate data and disclose where the chain is incomplete.
