There are no set requirements for the build of a GWO facility. However, each standard or module have specific requirements for equipment. Please review the appropriate standards you wish to provide in the future for further details.
For the Basic Safety Training (BST) (as an example), please see the requirements for the facilities below:
Theory training facilities
Facilities shall be designed to enable each course participant to see, hear and fully participate in the taught subject matter.
Practical training facilities
All facilities shall be maintained and where appropriate, inspected and tested in accordance with current national legislation and manufacturers’ recommendations. Risk assessments shall be conducted and documented for all training facilities. The Training Provider shall hold the required permits to operate the facilities. The learning process is facilitated by identical or comparable elements comparing the training environment and the course participant working environment. Identical or comparable elements enhances the application of what is learned. The practical training facilities and a training environment are expected to incorporate as many identical or comparable elements to a real wind turbine working environment as possible. The objective is that the practical training facility should enable each course participant to individually and/or as part of a team, see, hear and practice the taught subject matter in such a way, that it resembles the working practices in a real wind turbine environment. The facilities shall enable training to be executed by doing relevant work tasks end-to end under realistic simulated working procedures, and/or realistic simulated emergency situations (fire, first aid, evacuation or casualty rescue) end-to-end scenarios in a real or simulated wind turbine environment.
The required equipment for training shall be available and shall fulfill national legal requirements. The equipment shall be maintained, inspected and tested in accordance with current national legislation and manufacturers’ recommendations. Risk assessments shall be conducted and documented for all training equipment. The Training Provider shall hold the required permits to operate relevant equipment.
Example: Working at Height module states that “To ensure that for all fall protection equipment that may be used that there will be enough clearance below the anchor point, and to ensure that the course participants can experience a descent of sufficient duration for meaningful learning transfer, the GWO recommends that the anchor point is a minimum of 6.75 m (22.15’) above the ground or structure directly below the anchor point.”
Please note, in some of the standards there are some recommended dimensions for mock up (i.e., The ART module contains Hub and Nacelle mock ups).
Additional Facility and Equipment requirements can be found in the Requirements for Training,
In regards to the vendors, my best advice would be to contact a Training provider in your region that has already been GWO approved and arrange a facility visit to see what a good GWO facility looks like, a full list of training provider scan be found here: https://www.globalwindsafety.org/trainingproviders/findttraningprovider,
