We checked how reachable 876 diving companies are

What we checked, and why contactability is a real question

Commercial diving has a hiring culture that everybody describes the same way and nobody documents: you get work because someone knows you, or because someone who knows you told a supervisor your name. That is folklore, not evidence. But there is a way to get at the edge of it with data, which is to ask how much of the industry is even set up to be approached cold.

So we went through the company directory — all 876 records — and recorded four channels for each one: does it publish a website, a telephone number, a direct email address, and is there a named individual associated with the company that a stranger could plausibly address. The fourth is the interesting one, and the hardest to satisfy. A careers@ address is not a person. A "contact us" form is not a person. We counted a company as naming a person only where a human being is identifiable and reachable, not merely mentioned in a press release.

This is an audit of what companies publish, not of whether they reply. A phone number in a footer tells you nothing about whether anyone picks up, and an email address tells you nothing about whether the inbox is read. What it does tell you is whether a company has decided to be approachable in principle. That decision turns out to vary enormously by what kind of company it is.

The floor falls out at the fourth channel

The top of the distribution is unremarkable and the bottom of it is not. Phone numbers and email addresses sit almost level, at 585 and 574 companies respectively, a gap far too small across a directory of 876 to carry any meaning. LinkedIn drops to 365 companies, 41.7%. Then the fourth bar collapses: 27 companies out of 876 name someone you could ask for.

Seven companies in the whole directory publish all four: website, phone, email and a named person. Seven, out of 876, doing the complete job of being findable — and we should be careful about what that means, because it is not necessarily a sign of good practice. A small contractor run by two people who answer their own phone will publish all four naturally. A company with four hundred staff and a procurement department will publish none of them, on purpose. Contactability and size probably run in opposite directions, though the directory does not record headcount, so we cannot show that.

The likeliest reading of the 3.1% is not secrecy but structure. Naming a person on a public website means that person receives unsolicited approaches in volume, in a trade where the supply of qualified divers exceeds the number of berths at any given moment. Companies remove the name because the name becomes a cost. The 27 who keep it are either small enough that the volume is manageable, or deliberately positioned to receive inbound enquiries.

The 160 companies you cannot email or phone

160 companies, 18.3% of the directory, publish no direct email address and no telephone number. They have a website — every company in the directory does — but the website gives you a form.

A form is not the same as an address, and the difference matters more than it sounds. With an email address you control the message, you keep a copy, you can attach your certificates, and you can follow up in the same thread three weeks later. With a form you submit text into a field of unknown length, receive no record of what you sent, and have no thread to return to. You also cannot tell whether the form routes to a person, a shared inbox, or a ticketing system that quietly closes enquiries nobody reads.

We cannot tell from the directory how many of those 160 have a functioning form and how many have a broken one. That would require submitting enquiries and waiting for replies, which is a different study and one we have not done. What we can say is that for close to a fifth of the industry, the published route in is a channel that gives the sender no grip and no receipt.

Contractors answer. Operators do not.

Split the 876 by what the company does and the picture separates cleanly. Contractors — the diving companies themselves, 678 of the 876 records — are the most reachable category on both the channels that matter for a direct approach: 71.2% publish an email address and 69.5% a phone number. Operators, the 15 oil and gas companies in the directory, are the least reachable of all, with 13.3% publishing an email address.

Read the table by column and the inversion is obvious. Email falls from 71.2% to 13.3% as you move from contractors to operators; LinkedIn climbs the other way, from 36.3% to 73.3%. These are not two measurements of the same thing. They are two different theories of how a company should be approached.

An operator does not want your email because an operator does not buy diving services by email. It runs a prequalification process, a vendor portal and a tender cycle, and an unsolicited message is a thing to be deleted rather than routed. What it does want is to be legible as a corporate entity, which is what a LinkedIn page is for. Crewing agencies, at 72.7% on LinkedIn against 36.4% on email, sit in the same position for the opposite reason: their business is recruitment, LinkedIn is where recruitment happens, and an open email address on a crewing website invites a volume of CVs nobody can process.

Equipment suppliers are the balanced case, more or less evenly spread across all three channels, which fits a business that sells to anyone who can pay and therefore has no reason to filter.

What this means if you are trying to get hired

The practical reading is unflattering and worth stating plainly. If your plan is to email 876 companies, the directory says you have a real address for 574 of them, no address for 160, and a name for 27. Those 27 are the only approaches that can be personal, and personal is the only kind of approach that gets read. Everything else is a message to an inbox whose owner has already decided that unsolicited mail is not their problem.

That does not make the rest of the directory useless to you — it makes them the wrong first move. The 41.7% who are on LinkedIn are reachable through a channel where individuals are visible even when the company hides them, and the 44 crewing agencies, at 72.7% LinkedIn presence, are the category most obviously set up to be approached that way rather than by post. Our jobs and crewing pages cover how that part of the market is organised.

The wider picture from this series points the same way. The work is concentrated: only a handful of companies actually run saturation, as we counted in who actually runs saturation, and the industry clusters in a handful of regions, which the global map sets out. A short list of employers who genuinely do the work you are trained for, approached through a person, beats a long list approached through a form. If you are still at the stage of getting qualified, how to train as a commercial diver is the place to start instead.

One caution against over-reading all this: 3.1% is a statement about websites, not about the industry's willingness to hire. Companies that publish no name still recruit, constantly. They do it through supervisors, agencies, former colleagues and word of mouth — channels that leave no trace on a website and therefore cannot appear in this audit at all. The audit measures the front door. Most hiring goes through the side.

How we counted this

We read all 876 records in satdiver's company directory on 28 September 2026 and recorded four fields per company: website, telephone number, direct email address, and named contactable individual. A company counts as publishing a channel only if that channel is present on its own published material; we did not count numbers or addresses found through third-party aggregators, business registries or scraped lists. "Publish neither" means no direct email address and no telephone number — a company with a working contact form still falls into that group, and 160 companies do.

Three limits, in order of how much they should change your reading.

First, the 100% website figure is an artefact of how the directory is built, not a finding. Companies enter the directory because they have a published web presence, so a company without one is invisible to us. Any firm that operates entirely through relationships and a phone is missing from the 876 entirely, and there is no way for us to estimate how many of those exist.

Second, this is a record of what is published, not of what works. We did not phone the 585 numbers, email the 574 addresses, or submit the forms. A directory of published channels and a directory of channels that produce a reply are different documents, and only the first one exists.

Third, the named-person field is the most judgement-dependent of the four and therefore the one most likely to be wrong in either direction. We required a person who is both identifiable and reachable. A founder named in an "about us" paragraph with no way to contact them was not counted; a named sales manager with a direct address was. A different reviewer applying a looser rule would find more than 27, and a stricter one fewer. The category boundaries carry similar judgement: the 15 operators, 44 crewing agencies, 139 equipment suppliers and 678 contractors are our classification of what each company principally does, and companies that do two things are assigned to one.

The directory is also a moving target. Contact pages change, people leave, phone numbers get retired. These figures describe 28 September 2026 and will drift, and the same caveats apply to every other count in this series drawn from the same directories.
