Coming to Wind from Marine, Oil & Gas, Mining or the Military

The full list from GWO:

• Marine
• Mining
• Military
• Electrical substations
• Oil and gas
• Chemical, industrial and power plants

Here's what carries over from each, what's missing, and how to make the move.

What Every One of These Industries Has in Common

Employers like people from these backgrounds for the same reasons:

• You're used to strict safety systems. Permits to work, isolations, risk assessments and toolbox talks are nothing new to you.
• You follow procedures. In wind, you work from manuals and bulletins, every time.
• You know rotations. Weeks away from home, remote sites, shared accommodation, long shifts.
• You've worked in tough conditions. Bad weather, noise, tight spaces, heavy equipment.
• You've worked in a team where mistakes can hurt people.

These are often harder to teach than technical skills. That's your real advantage.

From Marine

What carries over:

• Engine room experience: diesel engines, pumps, hydraulics, lubrication systems, electrical systems
• Deck work: rigging, lifting, mooring, working with cranes
• Life at sea: vessel transfers, offshore routines, being away for weeks
• STCW basic safety training: personal survival, firefighting, first aid

What you'll still need: GWO BST. Your STCW certificates show you can handle yourself at sea, but they don't replace GWO Sea Survival or any other GWO module. Wind farms require GWO certificates in WINDA.

Where you fit best: offshore wind. Crew transfer vessels (CTVs), service operation vessels (SOVs) and installation vessels all need people who understand ships. Marine engineers and electricians often move into offshore service technician roles.

From Oil & Gas

What carries over:

• Offshore experience and the rotation lifestyle
• Work permit systems, isolations and lockout/tagout
• Mechanical, electrical, hydraulic and instrumentation skills
• Lifting operations, rigging and banksman work
• Rope access certificates (IRATA or SPRAT), which are also used in wind for blade inspection and repair

What you'll still need: GWO BST. OPITO certificates like BOSIET, FOET and HUET are respected, but they are a different system. They don't automatically count as GWO training. Expect to do GWO Sea Survival separately for offshore wind.

Where you fit best: offshore installation and service, and later supervisor and lifting roles. Many senior offshore wind people started in oil and gas.

From Mining

What carries over:

• Maintenance of heavy mobile and fixed plant: hydraulics, gearboxes, drivetrains, engines
• Electrical work on industrial equipment, often at higher voltages
• Strong isolation and lockout culture
• Confined spaces and harsh environments
• Remote sites and fly-in/fly-out style rotations

What you'll still need: GWO BST, and GWO BTT if you want a quick introduction to turbine systems. Your trade qualification (heavy-duty fitter, diesel mechanic, electrician) is the strongest thing on your CV.

Where you fit best: onshore service and maintenance, especially on large wind farms in remote areas. Fitters with gearbox and hydraulic experience are a good match for main component work.

From the Military

What carries over:

• Technical trades: vehicle mechanics, electricians, electronics and avionics technicians, engineers
• Discipline, procedure-following and a strong safety mindset
• Physical fitness, which GWO calls vital for wind technicians
• Teamwork under pressure, and being away from home for long periods
• Often first aid, rescue or working at height experience

What you'll still need: GWO BST, and GWO BTT if your military trade wasn't mechanical or electrical. Translate your military role into civilian language on your CV. A recruiter may not know what your job title meant, but they understand "maintained hydraulic and electrical systems on 40 heavy vehicles."

Where you fit best: any profile, depending on your trade. Technical trades go straight into service or installation. Leadership experience helps later when you move into lead technician or supervisor roles.

From Substations, Power Plants and Industry

Electricians and technicians from substations, power plants and chemical or industrial plants bring the skills that wind is short of most: electrical knowledge, high-voltage experience and isolation procedures. With GWO BST and some turbine familiarisation, you can move up quickly, and high-voltage roles are among the best paid in wind.

Will Your Old Certificates Count?

Short answer: not directly. Your STCW, OPITO, mining or military certificates won't turn into GWO certificates on their own, and you can't send them to GWO and ask for credit as an individual.

GWO does have a recognition system, often called merit. But it's built for training centres, colleges, schools and other education providers, not for individual people. It works like this:

1. The institution compares its existing programme with the matching GWO standard (a gap analysis).
2. It adds whatever is missing to the course.
3. It applies to GWO and gets the programme approved.

Once approved, the institution can offer courses where students finish with a real GWO certificate, recorded in WINDA.

What this means for you: look for colleges or training providers that run a GWO-recognised programme. Some technical schools and maritime or industry training providers include GWO certificates as part of a longer course. If you're choosing a course anyway, pick one that ends with GWO certificates in WINDA.

Otherwise, simply book GWO BST the normal way. It only takes a few days.

There are also a few short gap courses for very specific cases. For example, technicians who already hold certain turbine manufacturers' own basic technical certificates can take a short gap course to get GWO BTT instead of the full course. Ask a GWO training centre if this might apply to you.

How to Make the Move

1. Get GWO BST. Add Sea Survival if you're aiming offshore.
2. Consider GWO BTT if your background isn't mechanical or electrical.
3. Rewrite your CV for wind. Lead with transferable skills: systems you maintained, safety systems you worked under, lifting, isolations, rotations.
4. Don't undersell your experience. Many people from these industries start at a higher level than complete beginners, and some go straight in as experienced technicians.
