Ships

1,000 vessels indexed by their permanent seven-digit IMO number — the identifier assigned for life by Lloyd's Register on behalf of the IMO, which stays with the hull through ownership, flag, and name changes. The current set is curated (famous ULCVs, ULCCs, cruise flagships, historic vessels, plus representative bulkers, tankers, gas carriers, ro-ros, and offshore units) and is the working seafarer's lens onto specific hulls: flag of registry, classification society, current status, port-state-control detention history where recorded, and cross-links to the operator and shipyard.

How to use this directory: search by name or IMO in the box below, filter by ship type, or jump to /ships/by-flag for the flag-state breakdown. For real-time AIS tracking of any vessel by IMO, see MarineTraffic, VesselFinder, or Equasis (the latter has the most authoritative class + flag + manager data, though it requires registration).

Before joining: a vessel's flag, class, and P&I cover are visible on the certificates posted on the bridge or in the SMS; those are the authoritative live documents. The data here is a starting point — verify on board. The PSC banner shown on detail pages reflects an inspector's judgement at the time of inspection and is not a permanent reputation marker.

Ships directory: FAQ

What is an IMO number?
An IMO number is a unique 7-digit identifier assigned by Lloyd's Register on behalf of the IMO to a vessel for life, regardless of ownership or flag changes. Every commercial vessel of 100 GT or above carries a unique IMO number marked on the hull and stern. Our /ships directory is keyed by IMO number.
Is this ship still in service?
Each ship detail page shows the vessel's current status where known — in service, laid up, scrapped, or status uncertain. Status data is refreshed quarterly from a combination of MarineTraffic, Equasis, flag registries, and our own AIS sampling. Older vessels may have status discrepancies between sources.
What does the Port State Control (PSC) banner mean?
When a vessel has been detained or recorded with serious deficiencies at a port-state-control inspection in the Paris MoU, Tokyo MoU, or Indian Ocean MoU regimes within the last 24 months, our /ships pages render a PSC banner with the detention details. Detentions reflect the inspector's judgement at the time and are not a permanent reputation marker.
How do I find a ship's flag, class, and P&I cover?
Flag is shown on every ship page. Classification society and P&I cover are populated where we have them — these are not always public. The /classification-societies and /p-and-i directories cover the major registries and clubs. For dispute and complaint purposes, the most authoritative source is the certificates posted on the vessel's bridge or in the SMS.
