Saturation diving jobs and how hiring works
The contractors that run saturation spreads, the agencies that genuinely place divers, and exactly what a vacancy screens on.
Saturation diving work comes from two places: contractors hiring direct — Boskalis, Subsea7, TechnipFMC, Helix, Oceaneering, DOF and Micoperi all run saturation spreads and advertise on their own careers sites — and crewing agencies. Of the big agency names, only a few demonstrably place divers rather than marine crew. To be placed you need an IMCA-recognised certificate, a current diving medical, BOSIET with CA-EBS, MIST for UK waters, and an IMCA logbook with verifiable lockout hours and bell runs inside the last twelve months — vacancies screen on hours, not on years.
Who actually employs saturation divers
Start here, because a lot of the companies people assume are diving employers are not.
| Company | HQ | Saturation? | Notes |
|---|---|---|---|
| Subsea7 | London / Luxembourg | Yes | DSVs Seven Atlantic, Seven Falcon, Seven Pegasus. Seven Pegasus carries a twin-bell 18-man system rated to 300 m with two 18-man hyperbaric lifeboats. Diving heritage back to Stolt-Nielsen Seaway, 1970 |
| TechnipFMC | Newcastle upon Tyne (fleet base) | Yes | Deep Discoverer has an 18-person twin-bell 300 m system plus air diving; Deep Arctic and Deep Explorer carry 24-man chamber complexes |
| Boskalis | Netherlands | Yes | Five DSVs: BOKA Da Vinci, BOKA Polaris, BOKA Atlantis, Constructor, BOKA Topaz. Single and twin-bell saturation, 300 m, DP-2/DP-3. Advertises saturation roles directly on its own careers site |
| Helix Well Ops, now part of Hornbeck Offshore | Houston / Aberdeen | Yes — "core competency since 1987" | Seawell and Well Enhancer, each 18-man sat to 300 msw. Over 5,500 bell runs logged 2011–2025. Won a multi-year North Sea decommissioning contract starting Q2 2027 with saturation diving explicitly in scope. The Hornbeck merger took effect 1 September 2026 |
| Oceaneering | Houston | Yes | Air, mixed gas and saturation. One of the younger DSV fleets in the Gulf of Mexico; runs a portable hyperbaric reception facility out of Morgan City, Louisiana |
| DOF Group | Norway | Yes | Advertises "a complete range of diving services — saturation and air" |
| Micoperi | Ravenna, Italy | Yes | Owns portable systems: Fernanda 4 (4-man, 250 msw, spherical bell) and Castagna 1 (12-man, 3-man bell, 300 msw, built 2016, IMCA D 024 compliant). Modular, for vessel-of-opportunity work |
| KD Marine | Kintore, Scotland | No — surface/air only | Offshore surface diving and underwater intervention. An ODIA signatory |
| Hydrex | Antwerp | No | In-water ship repair; seals, thrusters, propellers, hulls. 24/7 emergency response |
| Subsea Global Solutions | Miami | No | Underwater ship repair and marine construction across 14 home ports |
| N-Sea | Dordrecht | Not stated | Survey, UXO, cable repair, IRM, decommissioning across the North Sea and Baltic |
| Fugro | Netherlands | Largely ROV-led | Supports construction "with diving teams and ROVs" but the emphasis is on ROV. Divested its Asia-Pacific subsea services business in 2016. Treat as a survey and ROV employer first |
Two more to strike off the list people circulate: Allseas is pipelay and heavy lift, and Van Oord is dredging and offshore wind installation — neither advertises a diving service.
Crewing agencies, honestly assessed
Agencies are how most freelance divers find work, but the big recognisable names are not all diving agencies. Several are marine crewing houses placing deck and engine officers onto vessels — useful if you want to work on a DSV as marine crew, not if you want to be in the bell.
| Agency | Base | Places divers? | What they actually do |
|---|---|---|---|
| Worldwide Recruitment Solutions (WRS) | Altrincham, UK; 5 offices worldwide | Yes — diving is an advertised specialism | Oil and gas, renewables, offshore and maritime |
| Subnet Services | UK and Philippines | Yes — states it recruits subsea, diving and ROV personnel; has advertised air diver roles in the Middle East | Oilfield recruitment plus competency training in ROV, fibre optics, welding inspection and NDT |
| NES Fircroft | Manchester; 80+ offices, 45 countries, 25,000+ contractors | Not verified as a diving discipline | Oil and gas, renewables, power, mining, life sciences. Also a contractor payroll operator |
| Atlas Professionals | Netherlands | Worth checking directly | Energy, marine and renewables, plus payroll and workforce management. Its diving discipline page could not be verified from here |
| OSM Thome | Arendal, Norway and Singapore; ~1,000 vessels, ~31,000 people | No — marine crew | Ship and crew management. The right route to marine crew work on a DSV, not to the dive team |
| Petroplan | UK | Not verified | Oil and gas, renewables, infrastructure staffing |
| Faststream Recruitment | Southampton, plus Americas and APAC | No diving roles verified | Shore-based maritime and shipping, crewing, cruise, superyacht, energy |
| Navis Consulting | Portsmouth, UK | No diving coverage found | Shipping, seagoing, marine engineering, superyacht |
| Progressive Recruitment | 33 offices incl. Houston | No diving coverage found | Utilities, manufacturing, oil and gas, renewables, engineering |
| Select Offshore | UK, six continents | No diver roles found | Listings skew to marine officers, engineers, ROV technicians and surveyors |
The practical conclusion: register with the two that demonstrably place divers, and apply direct to the contractors. Boskalis runs saturation diving supervisor vacancies on its own careers site. Direct application is a primary channel here, not a fallback.
Staff, freelance and "guaranteed days"
There are three engagement models and the wording in a vacancy tells you which one you are looking at.
| Model | How it works | Who gets it |
|---|---|---|
| Freelance / day rate | Paid only for contracted days. No pay between tours, no sick pay, no pension. Holiday pay rolled into the rate | The majority of saturation divers |
| Guaranteed days | Permanent employment status with a contracted minimum number of paid offshore days per year. Boskalis advertises its saturation diving supervisor role on exactly this basis | Increasingly common for supervisors and experienced divers |
| Salaried staff | Annual salary paid year-round, with offshore supplements. Lower peak, much higher floor | LSTs, supervisors, superintendents, and nationals in regimes with local employment rules |
On how agencies pay: most of the large agencies are contractor payroll operators as well as introducers — NES Fircroft supports 25,000-plus contractors, Atlas Professionals lists payroll and workforce management as a service line. Payment terms, umbrella arrangements and invoicing mechanics vary and are negotiated per contract; ask before you travel rather than after, and get the standby and weather-day treatment in writing.
The documents you need on file
An agency or contractor cannot put you forward without a complete file. A real vacancy gives the clearest picture of what is screened — Boskalis's saturation diving supervisor advert requires all of the following:
| Requirement | Detail |
|---|---|
| Diving qualification | Approved under the Diving at Work Regulations 1997 in the UK. HSE maintains an approved-qualifications list against four standards: SCUBA, Surface Supplied, Surface Supplied Top-Up, and Closed Bell. Without an approved qualification, competence must be assessed by an HSE-recognised organisation |
| Medical | Certificate of fitness to dive from an Approved Medical Examiner of Divers, valid up to 12 months, renewed annually. UKCS vacancies also specify an offshore (OGUK) medical |
| Survival training | OPITO-approved BOSIET with CA-EBS (compressed air emergency breathing system), plus MIST for UK continental shelf work |
| Logbook and hours | An IMCA professional diver's logbook with verified entries. The Boskalis supervisor role specifies a minimum of 400 lockout hours evidenced in the IMCA logbook over the last 12 months, a bell diving supervisor qualification with a minimum of 50 bell runs over 90+ days, an air diving supervisor qualification with at least 10 offshore commercial air dives, IMCA grading with verified bell qualification, IMCA Diving Supervisor CPD, and two years of DSV supervisory experience |
| First aid / DMT | Current first aid at work. Every offshore dive team must carry a current Diver Medical Technician |
| Passport, visas, vaccinations | Required; specifics vary by region — see below |
Australia adds its own set: ADAS Part 3 minimum for divers and Part 4 for closed bell, an ADAS Offshore Air supervisor qualification as the supervisory minimum, OPITO-recognised BOSIET, an MSIC, a Construction White Card, a current occupational diving medical, and general first aid with CPR and oxygen administration.
One thing worth knowing from both sides of the table: IMCA operates a public portal to verify a diver training certificate. Fabricated tickets are checkable, and they get checked.
What a diving CV must contain
There is no official template, so this is drawn from what vacancies actually screen on. The pattern is unmistakable: employers quantify experience in hours and bell runs within a rolling twelve months, not in years of employment. A CV that lists companies and dates will fail the first filter.
Include, prominently:
- Certification — level, issuing regime (HSE, ADAS, DCBC, ADCI…), certificate numbers, issue dates.
- Logged experience in numbers — bell runs, lockout hours, bottom time, with dates, matching your IMCA logbook exactly.
- Supervisor gradings and CPD status, if you have them.
- Expiry dates for the medical, BOSIET/CA-EBS and MIST. Agencies filter on these before they read anything else.
- DMT and first aid currency.
- Vessels and systems worked — named DSVs, bell type, system depth rating.
- Clients, operators and regions — it tells a supervisor whether you have worked to their standards.
- Passport and visa status, and how quickly you can travel.
Where the jobs are advertised
| Channel | What it is |
|---|---|
| Contractor careers pages | The most direct route. Boskalis, Subsea7, TechnipFMC, Oceaneering and DOF all recruit on their own sites |
| cDiver.net | Describes itself as the number one source for commercial diving jobs, with job alerts and a résumé bank |
| Energy Jobline | Large energy-sector board, partnered with recruiters including NES Fircroft |
| Oil and Gas People | UK and Aberdeen-focused energy platform, broadening into wind, solar, nuclear and LNG |
| Agency boards | WRS, NES Fircroft and Select Offshore all run their own job search and CV submission |
| Rigzone | Large oil and gas board but its category list carries no diving category — not a diving channel despite its size |
Visas and work permits
United Kingdom
Three routes matter. The Continental Shelf Worker visa is issued for twelve months at a time, multiple entry, for work on the continental shelf. The Skilled Worker visa suits workers who rotate between the continental shelf and territorial waters or who are on a long project — no maximum stay, but expensive, with English language and salary thresholds. The Frontier Worker Permit is for EU citizens only, who must have started UK employment by 31 December 2020 and who reside outside the UK.
Since 12 April 2023, regulations require employers or workers to notify the Home Office of offshore personnel arriving in and departing from UK waters. The separate offshore wind workers' concession has expired. Whether a visa is needed at all depends on nationality and on whether the work is inside territorial waters — within 12 nautical miles immigration control applies — or on the continental shelf.
Norway
Two regimes. Inshore commercial diving is regulated by Arbeidstilsynet, with Class A (to 30 m) and Class B (to 50 m) certificates; a foreign certificate holder must apply to Arbeidstilsynet for a permit before any inshore commercial dive. Offshore diving sits under Havtil's activities and technical regulations, with competence benchmarked to the EDTC/IMCA standards.
Australia
Offshore diving is regulated by NOPSEMA. Certification minimums are ADAS Part 3 for divers and Part 4 for closed bell, with ADAS Offshore Air as the supervisory minimum and ADAS Offshore Bell for closed bell supervision. DMTs need not hold ADAS, but every offshore dive team must carry a current one. Add BOSIET, an MSIC, a Construction White Card, a current occupational diving medical and legal work authorisation.
Middle East
We could not verify primary-source permit requirements for the UAE, Saudi Arabia or Qatar, and we would rather say so than guess. In practice, agency-sponsored placement is the live route — agencies advertising Middle East diving roles handle the sponsorship as part of the placement.
The market in 2026
Is there a shortage of saturation divers? The published evidence says yes, but it is thinner than the industry chatter suggests, and most of it comes from one source with a commercial interest.
- DEEP, March 2026: "There is a shortage emerging in the industry, because the average age of saturation divers keeps rising." DEEP is a training provider, so treat it as an interested party — but it is a dated, attributable statement.
- Training capacity as a signal: DEEP's HSE Closed Bell course is fully booked for every 2026 sitting and every advertised 2027 sitting, at £36,000 per seat, with only an interest register open. DEEP describes its new facility as the only closed bell saturation training system in the Northern Hemisphere — a claim that, if roughly right, tells you how narrow the pipeline is.
- OEUK, November 2025: flags "increasing competition for vessels, skilled people and specialist equipment as offshore wind activity expands."
- IMCA, April 2026: published updates to its assessment procedure for diving contractor membership, including new guidance on upgrading from surface supplied to saturation diving status. That is a standards development rather than a statement about shortage.
Decommissioning: the demand pipeline
The most concrete demand signal is not a diver shortage claim but the UK decommissioning programme, which is published and quantified. From OEUK's Decommissioning Report of November 2025:
| Metric | Figure |
|---|---|
| UK North Sea decommissioning spend, 2024 | £2bn — first time above that level |
| Forecast annual spend by end of the decade | ~£2.9–3bn |
| Crossover point | Decommissioning spend expected to surpass production investment as early as 2028 |
| Wells decommissioned in 2024 | 124 (78 platform, 40 subsea, 6 exploration and appraisal) |
| Subsea infrastructure removed in 2024 | 4,750 tonnes |
| Wells forecast for decommissioning to 2034 | ~2,000 |
| Subsea infrastructure to 2034 | over 95,000 tonnes |
| Pipelines to be removed to 2034 | 883 km |
The last two rows are the diver-relevant ones. Subsea infrastructure removal and pipeline work in the 50–200 metre band is exactly what saturation divers do, and 95,000 tonnes and 883 kilometres is a decade of it.
A concrete example of how that turns into jobs: Helix Well Ops holds a multi-year North Sea decommissioning contract starting Q2 2027, firm two years plus options, whose scope explicitly bundles saturation diving with the vessel, subsea intervention lubricator, ROVs and project management.
Questions
Which companies hire saturation divers?
Subsea7, TechnipFMC, Boskalis, Helix Well Ops (now part of Hornbeck), Oceaneering, DOF and Micoperi all run saturation spreads. Boskalis advertises saturation roles directly on its own careers site. Bibby Marine no longer does diving — that capability went to Boskalis via Rever Offshore.
Which agencies actually place divers?
Of the commonly cited names, WRS and Subnet Services demonstrably advertise diving roles. Several of the biggest maritime agencies — OSM Thome, Faststream, Navis — place marine crew rather than dive team. Applying direct to contractors is a primary channel, not a fallback.
What do I need on file to be placed?
An approved diving qualification from an IMCA-recognised authority, a current diving medical from an approved examiner, BOSIET with CA-EBS, MIST for UK waters, an IMCA logbook with verifiable entries, current first aid, and passport and visa status. For supervisory roles, add logged lockout hours and bell runs within the last twelve months, and IMCA CPD.
How many logged hours do supervisor roles want?
One current North Sea saturation diving supervisor vacancy specifies a minimum of 400 lockout hours in the IMCA logbook over the last twelve months, a bell diving supervisor qualification with at least 50 bell runs over 90+ days, an air diving supervisor qualification with at least 10 offshore commercial air dives, and two years of DSV supervisory experience.
Do I need a visa to work in the UK North Sea?
It depends on nationality and on where the work is. The Continental Shelf Worker visa covers work on the shelf; the Skilled Worker visa suits those rotating into territorial waters; EU citizens who started UK employment before 2021 may use a Frontier Worker Permit. Since April 2023 employers or workers must also notify the Home Office of offshore arrivals and departures.
Is the industry short of divers?
Training capacity says yes — every UK closed bell course sitting into 2027 is sold out, and the main provider says the average age of saturation divers keeps rising. But that provider sells the training, and IMCA has published no shortage statement. The firmer signal is the decommissioning pipeline: over 95,000 tonnes of subsea infrastructure and 883 km of pipeline to remove in the UK by 2034.
