Ownership

Who owns a ship

Published 9 August 2026 · updated 22 September 2026

Ask who owns a bulk carrier and there are up to five correct answers. They answer different questions, and only one of them is the company a broker should write to.

The roles

The reason the first row is nearly always a company with no staff is financing rather than secrecy. A ship is a large single asset carrying a large single liability, so she is usually held in her own company, financed against that company, and sold by transferring it. The name on the registry is therefore the name of a legal container. Writing to it achieves nothing, and this is not a sign that anybody is hiding: it is the ordinary shape of the industry.

The last row is the one that catches people out. A disponent owner does not own the ship at all. She holds it on charter from somebody who does and is re-letting it, so on that fixture she is the owner, and on the fixture above her she is the charterer. Neither statement is loose talk; both are correct at the same time, and who is who on a fixture walks the whole chain.

How to find out who owns a ship

The practical order, and it is an order rather than a menu, because each step costs more than the one before it:

1. Get the IMO number first. Everything downstream is keyed on it, and a name is not a substitute. If you have only a name, resolve it to a hull before you go any further: names collide and names change, and both failures are silent. Read the full IMO number guide for the check digit that tells you whether the seven digits you were given are even a real IMO.
2. Look at the operating layer. Commercial vessel data vendors carry technical and commercial managers with contact details, which is the answer to the question a broker usually means. This is where a chartering enquiry should go.
3. Check the flag and the class. The registry tells you whose law and whose certificates the ship carries, and it narrows where the registered owner is incorporated. See flag states and open registries.
4. Only then go to a registry-derived source for the registered owner. It is the slowest and most rationed step, and in most chartering situations it is also the least useful. Do it when you need the legal owner, for a sale, an arrest or a claim, and not to find somebody to send a cargo to.

If the question is "who do I e-mail about this ship", you are done at step two. If the question is "who legally owns this ship", step four is the only one that answers it, and the next section explains why that step is so much harder than it should be.

The mistake that hides entire fleets

Keying a company's fleet off the registered owner column alone looks reasonable and is wrong. An owner-operator is its own registered owner. A third-party manager appears only as technical manager. A holding company appears only as group owner. Do it that way and a manager with 478 ships shows a fleet of none, which is exactly the company a broker most wants to call.

A company's fleet is the union of all four columns, with each hull labelled by the role that company plays for that ship. The role varies by ship, not by company. The same manager can be technical manager on twenty hulls, commercial manager on twelve of those twenty, and neither on the rest of a fleet she is nonetheless spoken of as running.

Why nobody can sell you registered owners

This is the structural gap in the whole market, and it is worth understanding before paying anyone for a contact database.

So the contact chain runs through the commercial manager first, then the technical manager, then the registered owner. Anyone promising bulk registered owners is selling you the operating layer with a different label on it.

The arithmetic of the cap is worth doing once, because it settles the question. At roughly 78 hulls per seven-day period, a registry-derived source would take well over twenty years to walk a fleet of ninety thousand, by which time the early answers would be a decade stale. There is no clever way around that, which is why in the register behind this site 88,145 of 101,850 hulls still carry a placeholder registered owner. The honest thing a database can do with that column is admit it is empty, rather than copying the technical manager into it and calling the field populated.

Coverage is not uniform, and averages hide it

Contact reachability concentrates in the tonnage that actually trades. Measured by segment:

The small end is one-ship regional owners with no chartering desk to write to. Judge a contact database against the tonnage you actually fix, not against a whole-fleet percentage. A headline figure averaged over the whole register is dominated by the small tonnage nobody is enquiring about, and it will understate the coverage that matters to a Panamax desk and overstate it for anyone working coasters.

A desk address beats a named one

An address like chartering@ survives staff turnover; firstname.lastname@ leaves with the person. A contact database that does not distinguish the two will quietly rot at whatever rate the industry changes jobs.

The rot is invisible, which is what makes it dangerous. A named address that has been deactivated usually bounces, and a bounce is at least information. A named address that has been handed to somebody else, or quietly forwarded to a colleague who never reads it, accepts mail and does nothing, so the desk records an enquiry sent and hears nothing back and draws the wrong conclusion about the owner rather than about the address.

Company names are not a key either

A shipping company's name is written a dozen ways across registers. Soki Kisen Co., Ltd. and SOKI KISEN CO.,LTD. are one company, and a case-insensitive match still treats them as two. The IMO company number is the only stable key: issued once per legal entity, never reissued.

Hull names have the same disease and worse. In the register behind this site 5,027 folded names are shared by more than one hull, covering 14,252 hulls, and 11,869 hulls have been inspected under more than one name. So a lookup that starts from a name has to return a ranked list of candidates rather than one answer, and a system that quietly picks the first row will attribute one company's ship to another with no sign that anything happened. That failure and the ranking that avoids it are the subject of ship names change, and they are not unique.

The Vessel Register behind this site is keyed on that number throughout, and carries the four ownership roles separately rather than flattening them into a single owner field. It records which of the four is usually missing against a hull, and what becomes of a correction your own desk makes.

Questions people ask

Who do I actually e-mail about a ship?

The commercial manager, in almost every case. That is the party that fixes the ship and the one a cargo should be addressed to. The registered owner is usually a single-ship company with no chartering desk behind it, and writing to it is how an enquiry goes nowhere quietly.

What is a disponent owner?

A charterer who has taken the ship on time charter and is now offering her out again. To the next charterer down the chain they are the owner for every practical purpose, and they are the party whose name goes on that fixture, but they do not appear in any registry.

Why can nobody sell me a database of registered ship owners?

Because the registries that hold it do not publish it in bulk. Equasis carries registry-derived ownership and is free to registered users, and both of those are true at once: it is readable a hull at a time and it is not available as a file. Every vendor selling ownership data at scale is selling the operating layer, which is managers, and that is a different column.

What is the difference between a technical manager and a commercial manager?

The technical manager runs the ship: crew, maintenance, class, the safety certificates. The commercial manager sells her: fixtures, freight, laytime. The same firm often does both on one hull and only one of them on the next, so the role has to be recorded per ship rather than per company. Only the commercial one answers a chartering enquiry.

How can I find who owns a ship?

Start from the IMO number, never the name. Then read the operating layer from a commercial vessel data vendor for the managers, and the flag registry and class society for the registered owner. Expect the last of those to be the one you cannot get, and expect coverage to be uneven rather than uniformly thin.
