Ownership

Who owns a ship

Published 9 August 2026 · updated 17 October 2026

If you ask who owns a bulk carrier, there are up to five correct answers. Each answers a different question, and only one of them is the company a broker should write to.

The roles

The first row is nearly always a company with no staff, and the reason is financing, not secrecy. A ship is one large asset with one large liability, so it is usually held in its own company, financed through that company, and sold by transferring the company. The name on the registry is a company that exists only to hold the ship, so writing to it achieves nothing. This does not mean that anyone is hiding. It is how the industry normally works.

The last row often confuses people. A disponent owner does not own the ship at all. It holds the ship on charter from someone who does and lets it out again, so on that fixture it is the owner, and on the fixture above it, it is the charterer. Both statements are correct at the same time. Who is who on a fixture explains the whole chain.

How to find out who owns a ship

Follow these steps in order, because each step costs more than the one before it:

1. Get the IMO number first. Everything after this depends on it, and a name cannot replace it. If you have only a name, match it to a hull before you do anything else, because names are shared and names change, and you will not notice either problem. Read the full IMO number guide for the check digit that tells you whether the seven digits you were given are a real IMO, or check the IMO number and look up the ship with the free tool.
2. Look at the operating layer. This means the managers who run and trade the ship. Commercial vessel data vendors list technical and commercial managers with contact details. That answers the question a broker usually means, and it 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 down where the registered owner is incorporated. See flag states and open registries.
4. Only then use a registry-based source for the registered owner. This is the slowest step, with the strictest limits, and in most chartering work it is also the least useful. Do it when you need the legal owner for a sale, an arrest or a claim, not to find someone to send a cargo to.

For the lookup itself, source by source, see how to find a ship's owner from its IMO number.

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

The mistake that hides entire fleets

Building a company's fleet from the registered owner column alone looks sensible, but it 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. If you use only that column, a manager with 478 ships shows a fleet of none, and that is exactly the company a broker most wants to call.

A company's fleet is all four columns combined, with each hull labelled by the role the company plays for that ship. The role changes from ship to ship, not from company to 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 that people still say it runs.

Why nobody can sell you registered owners

This is the basic gap in the whole market, and it is worth understanding before you pay anyone for a contact database.

So the contact order is the commercial manager first, then the technical manager, then the registered owner. Anyone who promises registered owners in bulk is selling you the operating layer under a different label.

Do the calculation once, and the answer is clear. At roughly 78 hulls per seven-day period, a registry-based source would need well over twenty years to cover the world's merchant fleet, by which time the first answers would be ten years out of date. There is no clever way around this, which is why, in the register behind this site, 88,145 of 101,900 hulls still carry a placeholder registered owner. The honest thing a database can do is admit that column is empty, rather than copy the technical manager into it and call the field filled.

Coverage is not uniform, and averages hide it

Contacts are easiest to find for the ships that actually trade. Measured by segment:

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

A desk address is better than a named one

An address like chartering@ keeps working when staff change. firstname.lastname@ leaves with the person. A contact database that does not tell the two apart becomes less accurate every time people in the industry change jobs.

You cannot see this loss of accuracy, and that makes it dangerous. A closed named address usually bounces, and a bounce at least tells you something. But a named address given to someone else, or forwarded to a colleague who never reads it, accepts mail and does nothing. The desk records an enquiry as sent, hears nothing back, and draws the wrong conclusion about the owner when the problem is the address.

Company names are not a reliable identifier either

A shipping company's name is written in a dozen ways across registers. Soki Kisen Co., Ltd. and SOKI KISEN CO.,LTD. are one company, but a match that ignores capital letters still treats them as two. The IMO company number is the only stable identifier, because it is issued once for each legal entity and never reused.

Ship names have the same problem, and worse. In the register behind this site 5,027 names are shared by more than one hull, covering 14,252 hulls (comparing names without capital letters or punctuation), and 11,869 hulls have been inspected under more than one name. So a search that starts from a name must return a ranked list of possible ships, not one answer. A system that picks the first row without telling you will give one company's ship to another with no sign that anything went wrong. That problem, and the ranking that avoids it, are covered in ship names change, and they are not unique.

The Vessel Register behind this site uses that number as its identifier everywhere, and keeps the four ownership roles separate instead of squeezing them into one owner field. It shows which of the four is usually missing for a hull, and what happens to a correction your own desk makes.

If you own or manage the ship, you can offer it to every desk on one public board.

Questions people ask

Who do I actually e-mail about a ship?

The commercial manager, in almost every case: that is the company that fixes the ship, and the one to send a cargo to. The registered owner is usually a one-ship company with no chartering desk, and an enquiry sent there usually gets no answer.

What is a disponent owner?

A charterer who has taken the ship on time charter and now lets it out again. To the next charterer down the chain, they are the owner in every practical way, and their 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 this data do not publish it in bulk. Equasis has registry-based ownership and is free to registered users, but you can read it only one hull at a time and cannot get it as a file. Every vendor selling ownership data at scale is selling the operating layer, which is the 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 and the safety certificates. The commercial manager sells the ship’s time: fixtures, freight and laytime. The same firm often does both on one hull and only one on the next, so the role must be recorded for each ship, not for each company. Only the commercial manager answers a chartering enquiry.

How can I find who owns a ship?

Start from the IMO number, never the name. Then get the managers from a commercial vessel data vendor (the operating layer), and the registered owner from the flag registry and class society. Expect the registered owner to be the one you cannot get, and expect coverage to be good for some segments and poor for others, rather than equally low everywhere.
