The Global Wind Organisation (GWO) does not itself require a medical examination. But you must declare yourself fit, and your employer may well require a certificate. Here is what GWO says.
GWO makes no requirements for a medical assessment to take GWO training. GWO says it is the employer's decision which certificates, training and medical examinations you need to work for them, and that it also depends on the type of work you will do.
You do, however, have to declare that you are physically and medically fit to take part. GWO's requirements for training providers include a template self-assessment form, in which you confirm you have read the list of risks and that nothing prevents you from taking part.
If there is any doubt about your medical fitness during the course, the training provider stops the training and seeks a physician's advice. The GWO template asks you to tell the training provider if you have, for example:
The form is an example. The training provider must adapt it to the legislation where the training centre is located, so your form may look slightly different.
GWO sets no weight limit for course participants. The training provider must, however, follow the equipment recommendations and national legislation.
According to GWO, it is the employer who decides. If your contract, mobilisation letter or course confirmation requires a medical or a fitness test, that is where the requirement comes from, and where you can see which certificate.
The Energy Institute has published guidance on medical fitness assessment of wind turbine workers, aimed at a consistent assessment across providers. At our clinic the wind industry certificate is called Wind Medical (EI 3583). If your employer asks for OEUK and a Chester Step Test, you can take both in one visit with the package GWO Wind OEUK m. Chester Step test.
Some GWO modules must be refreshed every two years for the certificate to stay valid. This applies to Basic Safety Training, Enhanced First Aid, Advanced Rescue Training and Control of Hazardous Energies.
You can renew up to two months before expiry and keep your original date. Renew earlier and the certificate gets the new date. Let it expire and you must take the full course instead of the refresher.

Not according to GWO. GWO makes no requirements for a medical assessment, but your employer may require one. You must complete a medical self-assessment in any case.
GWO sets no weight limit, but the training provider must follow the equipment recommendations and national legislation.
Basic Safety Training, Enhanced First Aid, Advanced Rescue Training and Control of Hazardous Energies must be refreshed every two years.
Yes. Up to two months before expiry you keep your original date. Renew earlier and the certificate gets the new date.
