What is the difference between OPITO and GWO training?
If you work in the offshore oil and gas industry or the wind energy sector, chances are you have come across both OPITO and GWO certifications. These two training standards are often mentioned together, yet they serve different industries and have distinct requirements. Understanding the difference between OPITO training and GWO training helps you book the right course, stay compliant, and avoid delays on your next project.
What is OPITO training and who needs it?
OPITO training is a globally recognized safety certification standard designed for professionals working in the oil and gas industry, particularly in offshore environments. OPITO sets the benchmark for offshore safety competence and is mandatory for anyone working on oil and gas platforms, rigs, or related offshore installations.
The OPITO framework covers a wide range of courses, from initial entry-level certifications to refresher and advanced programs. Key OPITO courses include:
- BOSIET (Basic Offshore Safety Induction and Emergency Training) for first-time offshore workers
- FOET (Further Offshore Emergency Training) as a refresher for experienced offshore professionals
- HUET (Helicopter Underwater Escape Training) for those traveling to offshore installations by helicopter
- T-BOSIET and T-FOET for professionals working in tropical regions
- MIST and IMIST for workers in the oil and gas industry more broadly
OPITO certification is typically required by oil and gas operators, drilling contractors, and service companies as a condition of entry to offshore sites. Without a valid OPITO certificate, access to most offshore oil and gas installations is not permitted.
What is GWO training and who is it designed for?
GWO training, developed by the Global Wind Organisation, is a safety training standard specifically designed for professionals working in the wind energy sector. GWO sets minimum safety requirements for technicians and other personnel working on wind turbines, both onshore and offshore.
The GWO Basic Safety Training (BST) package is the foundation of GWO certification and covers five core modules:
- Manual Handling
- First Aid
- Fire Awareness
- Working at Heights
- Sea Survival (required for offshore wind roles)
GWO training is required by wind energy employers and project operators across Europe, the United States, and other major wind markets. As the offshore wind industry continues to grow rapidly in 2026, GWO certification has become an essential requirement for wind technicians seeking employment on turbine installation and maintenance projects.
What is the difference between OPITO and GWO training?
The key difference between OPITO and GWO training is the industry each standard serves. OPITO is the safety certification framework for the oil and gas industry, while GWO is the equivalent framework for the wind energy sector. Although both address offshore safety, they are separate accreditation systems with different course content, governing bodies, and certificate validity periods.
Here is how the two standards compare across the most important dimensions:
- Governing body: OPITO is managed by OPITO International; GWO is managed by the Global Wind Organisation
- Primary sector: OPITO covers oil and gas; GWO covers wind energy (onshore and offshore)
- Course content: OPITO focuses on oil and gas emergency response, helicopter safety, and offshore survival; GWO focuses on working at heights, manual handling, first aid, fire awareness, and sea survival
- Certificate validity: OPITO certificates such as BOSIET are typically valid for four years, with a refresher (FOET) required before expiry; GWO modules are generally valid for two years
- Recognition: OPITO is accepted globally by oil and gas operators; GWO is accepted globally by wind energy operators
Can OPITO and GWO certificates overlap or replace each other?
OPITO and GWO certificates cannot replace each other. They are issued by separate governing bodies for different industries and are not interchangeable. An OPITO BOSIET certificate does not satisfy a GWO requirement, and a GWO Sea Survival certificate does not replace an OPITO HUET qualification.
That said, some professionals working across both sectors may hold both types of certification simultaneously. For example, a technician who transitions from oil and gas to offshore wind will need to obtain GWO certification in addition to their existing OPITO credentials. There is no formal credit transfer or exemption process between the two frameworks.
Which training do you need for offshore wind projects?
For offshore wind projects, GWO certification is the standard requirement. Most offshore wind employers and project developers require the full GWO Basic Safety Training package as a minimum, including the Sea Survival module that applies specifically to offshore environments.
However, some offshore wind projects may also require OPITO certification depending on the nature of the work or the proximity to oil and gas infrastructure. This is more common in regions where oil and gas and wind operations overlap, such as the North Sea. Always check the specific requirements set by your employer or the project operator before booking your training.
If you are unsure which certifications apply to your role, reviewing the OPITO offshore courses available can help clarify which qualifications are relevant to your situation.
Where can you get OPITO and GWO certified training?
Both OPITO and GWO certified training must be completed at an accredited training center recognized by the respective governing body. Choosing an accredited provider ensures your certificate is valid and accepted by employers and project operators worldwide.
When selecting a training provider, look for:
- Official accreditation from OPITO International or the Global Wind Organisation

Frequently Asked Questions
How long does it take to complete OPITO or GWO training?
OPITO courses vary in duration depending on the certification level. A BOSIET course typically takes 2–3 days, while a FOET refresher can often be completed in 1–2 days. GWO Basic Safety Training (BST) covering all five modules usually takes 3–5 days in total, though individual modules can sometimes be taken separately over a shorter period. Always confirm the exact duration with your training provider when booking.
What happens if my OPITO or GWO certificate expires before I can complete a refresher?
If your certificate expires, you will generally need to retake the full course rather than a shorter refresher program. For OPITO, an expired BOSIET means you must complete a new BOSIET rather than a FOET. For GWO, expired modules must be individually retaken. To avoid this, set a reminder well in advance of your expiry date and book your refresher early, especially during peak periods when course availability may be limited.
Can I take OPITO and GWO training at the same time or back to back?
While the two certifications are independent, there is no rule preventing you from completing them in close succession. Many professionals transitioning between industries or working across both oil and gas and offshore wind choose to schedule their GWO and OPITO courses within the same week or trip to minimize travel and downtime. Check with your training provider to see if combined scheduling is possible at their location.
Are there any medical or fitness requirements before attending OPITO or GWO training?
Yes, both OPITO and GWO training involve physically demanding elements such as water survival exercises, working at heights, and emergency drills. OPITO courses typically require a valid offshore medical certificate (such as an OGUK or equivalent) before participation. GWO training also requires participants to meet certain fitness standards, particularly for the Sea Survival and Working at Heights modules. Check the specific pre-course medical requirements with your training provider before booking.
Is GWO training recognized globally, or only in certain countries?
GWO certification is globally recognized and accepted by wind energy operators and project developers across Europe, North America, Asia-Pacific, and beyond. As the wind energy industry has expanded internationally, GWO has become the de facto global standard for wind technician safety training. However, some regions or specific project operators may have additional local requirements on top of GWO, so it is always worth confirming with your employer or project manager before mobilizing.
What is the difference between GWO BST and GWO BST Enhanced, and do I need the Enhanced version?
GWO Basic Safety Training (BST) covers the five core modules: Manual Handling, First Aid, Fire Awareness, Working at Heights, and Sea Survival. GWO BST Enhanced adds more advanced content to certain modules, particularly Working at Heights and Sea Survival, and is required for roles involving more complex or high-risk tasks on offshore wind installations. Whether you need the Enhanced version depends on your specific job role and the requirements set by your employer or project operator.
Can my employer book and pay for OPITO or GWO training on my behalf?
Yes, most accredited training providers, including FMTC Safety, accommodate both individual and corporate bookings. Employers can arrange and pay for training for individual employees or entire teams, often with the option to receive consolidated invoicing and documentation. If you are coordinating training for a group, contacting the provider directly is the most efficient route, as they can help schedule courses around your project timelines and team availability.
