Commercial diving is still an overwhelmingly male profession, even though there's no technical requirement that justifies it. The barriers that women in the sector describe are about access, about equipment designed for a different body, about accommodation on board and about team culture, more than about physical capability or regulation.
On a commercial diving job it's common to go weeks without seeing a single woman on the team. That's not just an impression: it's the reality of a sector that remains one of the most male-dominated there is, with no technical reason to explain it.
It's worth looking at this with data where it exists, and with caution where it doesn't, because on this topic there are a lot of figures repeated with no source behind them.
How many there are: what can be said with confidence
There's no international census of commercial diving that would let anyone say precisely how many women work in the sector. Certifying bodies don't systematically publish data broken down by sex, markets are national, and many professionals work campaign by campaign for different contractors.
What can be said, based on what schools and associations report, is that women's presence is a small minority, and that it's somewhat higher in training than in ongoing offshore work. In other words: proportionally more women enter training than end up staying embarked long-term. That gap between entering and staying is probably the most telling figure of all.
We cover the general context of the trade, its size and how it's spread across markets, in how many saturation divers there are in the world.
The barriers that get described
Access to the first job
Commercial diving runs on a logic of trust and recommendation: training opens the door, but the first berth almost always comes through a personal contact, as we explain in how to get your first job as an offshore diver. In a sector where almost all the contacts are men, that dynamic acts as a filter without anyone designing it that way on purpose.
Equipment designed for a different body
The trade's kit was developed around male proportions. Helmets, harnesses, drysuits and hot water suits in small sizes or with proper fit have for years been hard to come by, and badly fitted equipment isn't just uncomfortable: it compromises safety and performance.
It's a real problem with a simple technical fix, and one that also affects anyone of small build, whatever their sex. In equipment we cover the trade's standard equipment.
Accommodation and logistics on board
Modern vessels and platforms usually handle this without difficulty, with cabins and heads laid out appropriately. On older installations, with shared bunks and limited communal space, it gets more complicated, and it fairly often becomes the reason given for not bringing a woman onto a team, even though it's an infrastructure problem, not a capability one.
Team culture
This is the hardest barrier to measure and the one that comes up most in professional accounts: the feeling of being permanently on trial, having to prove what's assumed of others by default, condescending treatment, and isolation in the intense shared living of weeks offshore. None of that shows up in a safety report, but it explains a large share of the people who leave.
Rotations and personal life
Long campaigns away from home affect anyone, as we describe in rotations and time at home. In societies where caregiving is still shared unevenly, that model penalises women disproportionately, and it's a recognised cause of people leaving the sector midway through their career.
What isn't a barrier
It's worth being clear about this, because a lot of confusion goes around.
There's no rule that excludes women. The recognised certification schemes we compare in which certification to choose apply the same requirements to everyone, and the medical and physical fitness criteria assess the ability to do the job, not sex.
Nor is there a physiological argument that supports exclusion. The demands of the trade are real and serious — functional strength, endurance, tolerance to cold and exertion — but they're individual and measured individually. Preparing for those tests is the same for any candidate.
On pregnancy, the professional guidance is unambiguous: no diving, and no hyperbaric exposure, during pregnancy. It's a recognised contraindication in diving medicine, and managing it is part of the employment relationship, the same as other temporary medical situations.
What's changing
There are concrete shifts, though uneven across markets. Schools are recording more applications from women than a decade ago, and some actively publicise it. Networks and associations for women in maritime and underwater professions now exist as a substitute for the informal network that was historically missing. End clients, especially the big energy operators, are building diversity criteria into their contracts, and that puts pressure on contractors.
The trade itself is also diversifying. The growth of inspection work, of work with remotely operated vehicles, and of technical roles — covered in ROV versus diver— widens the routes into the sector beyond physical work in the water.
Practical recommendations
For anyone considering getting into the trade, the advice doesn't differ from the general advice, though some points carry more weight:
- Choose a school by asking explicitly about prior experience with women students, equipment available in appropriate sizes and real job placement. The list is in schools.
- Prepare for the physical demands well in advance and with a clear plan, rather than improvising on the course.
- Document every working hour rigorously: in an environment where you're more exposed to scrutiny, a spotless record is your best argument.
- Build a network from day one, at courses, trade shows and associations. In community y eventos there are some starting points.
- Ask directly, during the hiring process, about accommodation, equipment and the company's policy. The answer tells you a lot before you ever embark.
The honest conclusion is that commercial diving isn't a trade closed off by rule, but it is one that still isn't designed to make getting in easy. Changing that depends less on the women applying than on the companies, schools and teams already inside it.
What companies and schools can do
Most of the barriers described here aren't solved from the side of the person trying to get in, but from the side of the people already inside. The concrete measures are well known and far from spectacular.
On equipment, keeping appropriate sizes and fittings as part of the normal inventory, not as an exception that has to be specially requested. On infrastructure, planning onboard accommodation in advance instead of using it as a reason to rule out candidates. On selection, relying on verifiable criteria — certification, logged hours, references — rather than the informal contact network, which is exactly where the unintended filtering happens.
And within the team, something as basic as setting a standard of conduct on board and enforcing it. The accounts describing people leaving rarely talk about serious incidents, but about a steady wear-down that nobody corrects because nobody feels responsible for doing so.
It's also a practical matter. The sector has spent years flagging the difficulty of bringing in the next generation of professionals; effectively ruling out half the possible candidates doesn't help solve that.
It's worth adding a note of caution about sources. On this topic, very specific percentages circulate, repeated from article to article, that don't trace back to any verifiable study. We've chosen to describe what can be supported — a small minority presence, higher in training than in ongoing work, and barriers that recur consistently across professional accounts — rather than give a figure that sounds precise but isn't.
Frequently asked questions
Can a woman be a commercial or saturation diver?
Yes. There's no regulatory restriction by sex in the main commercial diving certification schemes, and women work in industrial diving, inspection and saturation in various markets.
How many women are there in the sector?
It's a very small minority, and there's no reliable global census that would give an exact figure. The estimates that circulate come from schools and associations, and they agree on describing a small presence, somewhat higher in training than in offshore work.
Are the physical tests the same for everyone?
Yes. The physical and medical fitness criteria applied by schools and certification schemes are the same regardless of sex, and they're aimed at the ability to do the job safely.
Is the equipment designed for different body types?
It was historically designed around male sizes and proportions. Helmets, suits and harnesses in small sizes or with proper fit have long been hard to find, though the range on offer has been widening.
How is onboard accommodation handled?
It depends on the vessel. Many modern units have cabins and heads that allow for a proper layout, but on older installations or with shared bunks, the issue still causes logistical friction that's sometimes used as an excuse not to hire.
What's changing?
Women's presence in schools, the existence of professional networks, clients demanding more on diversity, and the growing availability of better-fitted equipment. The change is slow and uneven depending on the market.
