4. SCOPE Global Wind Organisation is a non-profit body founded by the wind turbine manufacturers and owners. Our members strive for an injury free work environment in the wind turbine industry, setting common international standards for safety training and emergency procedures. This standard describes the requirements for Basic Technical Training modules that are recommended and endorsed by the members of GWO. The Standard comprises of five modules:

Mechanical

Electrical

Hydraulic

Bolt Tightening

Installation

This standard has been developed in response to the demand for recognisable basic technical training in the industry and has been prepared in co-operation between the members of GWO based on risk assessments and factual incident and accident statistics from G+ and the wind industry. GWO members agree that everyone working on one of their properties (wind turbine generators, sub stations, etc.) shall complete Basic Technical Training courses and subsequent company specific training relevant for their assignments. All work shall be done in teams of at least two competent persons. Exemptions from the above can be made based on internal company rules. General feedback on this document can be sent to info@globalwindsafety.org. See globalwindsafety.org on how to raise a complaint about a training provider or report a safety incident occurring during training. 5. GENERAL REQUIREMENTS FOR THE BASIC TECHNICAL TRAINING Upon completion of the Global Wind Organisation (GWO) Basic Technical Training (BTT), participants will possess an awareness of the hazards encountered when working on hydraulic, mechanical, electrical, and installation systems, and when working with energy powered bolt tightening and how to control and mitigate these hazards, preparing candidates for working both on and offshore in the wind power industry. These training modules can be delivered independently of one another or as stand-alone training. The bolt tightening and installation modules are not part of the mandatory BTT training, and it is up to the duty holder to decide if this should be mandatory training. 5.1 Overview The GWO Basic Technical Training is divided into the following 5 modules:

Module 1:

Mechanical

Global Wind Organisation www.globalwindsafety.org

10 / 262

Technical Training

Basic Technical Training Standard/ V8 2023-05-02

Module 2: Module 3: Module 4: Module 5:

Electrical Hydraulic

Bolt Tightening

Installation

5.2 Target Group The Basic Technical Training modules are targeted at candidates who have no previous experience of hydraulic, mechanical, electrical or installation systems, or working with energy powered bolt tightening, but may also be used to upskill candidates who have some knowledge but not of its application in wind turbines. 5.3 Aims and Objectives This BTT Training prepares participants for further company specific training by providing them with the necessary training to perform basic hydraulic, mechanical, electrical, bolt tightening and installation tasks. This course will not make the participant a trained person who is allowed to perform hydraulic, mechanical, electrical, bolt tightening or installation work without supervision. 5.4 Duration of the Basic Technical Training Standard Modules The total contact time for completing the Basic Technical Training Standard is between 35 and 36 hours. This is based on the times given in the module timetables and summarised in tables 5.4.1, 5.4.2 and 5.4.3 below.

The training provider must not exceed the time per day given in table 5.4.4 below.

Note

If a participant fails to meet the demands of a Basic Technical Training Module, they shall attend a new training in that module. 5.5 Validity Period The Basic Technical Training is an enduring qualification, so a validity period does not apply to this training. This is based on the expectation that the participant is actively working in a wind turbine environment. If there is an extended period of absence from applying the skills, retraining and recertification may be required according to national legislation and company policy. A maximum interval between successful completion of the BTT Hydraulic, Mechanical, Electrical, Bolt Tightening and Installation modules does not apply. This is based on the expectation that the participant is actively working in a wind turbine environment. If there is an extended period of absence from applying the skills, retraining and recertification may be required according to national legislation and company policy. 5.6 Course Codes

5.7 Participant Prerequisites All personnel participating must meet the participant prerequisites described in the GWO Requirements for Training.

There are additional prerequisites for both the Bolt Tightening and Installation modules:

a. Before attending the BTT Bolt Tightening Module participants must first complete the BBT Mechanical Module. b. Before attending the BTT Installation Module participants must first complete both the BTT Mechanical and BTT Bolt Tightening modules. Furthermore, personnel in the wind service industry must be able to read and write to a sufficient standard to be able to carry out instructions and complete the required documentation. It is an advantage if participants are able to read, speak and write English. 5.8 Instructor Qualification Prerequisites A competent GWO BTT instructor must adhere to the instructor requirements for GWO training.

6. GENERAL RESOURCES REQUIRED TO DELIVER THE BTT MODULES

The training provider shall ensure that staff, facilities, and equipment are in place to support the training of participants. 6.1 Practical Training Facilities A practical workshop is required that has enough space to accommodate 8 participants, with a respective work area each of approximately 3 square metres. 6.2 Handouts Handouts must be given to the participants containing, as a minimum:

Electrical symbols mentioned in the BTT Standard

Global Wind Organisation www.globalwindsafety.org

13 / 262

Technical Training

Basic Technical Training Standard/ V8 2023-05-02

Hydraulic symbols mentioned in the BTT Standard

Formulas used (Pascal’s Law, Ohm’s Law, Torque…)

These handouts could be used as reference for the participants during the entire course and also during the test at the end. For the Bolt Tightening Module handouts (work instructions, manuals, PDAs and checklists) are found in Annexes 2 and 3. In circumstances where the training is being held on behalf of an OEM or owner operator, equivalent company specific documents may be used instead. 7. USING THIS STANDARD TO DEVELOP TRAINING The training in this standard is designed around the GWO taxonomy described in the GWO Requirements for Training. Theoretical and practical activities must be delivered according to the defined taxonomic level in order to reach the described learning objectives. When teaching about equipment, a generic approach to shall be applied aiming to avoid additional potential product specific formal training after completion of this training. However, national or regional legislation, company gap analysis and location specific risk assessments may require additional product specific familiarisation which is the responsibility of the duty holder.

In addition to this, all training based on this standard including all related resources shall, as a minimum, meet the requirements described in the GWO Requirements for Training.

8. ADMINISTRATION AND CERTIFICATION OF MODULES 8.1 Participant Performance Assessment

The participants will be assessed separately on each module according to the learning objectives, by means of direct observation and supplementary oral questions where appropriate (formative evaluation). Furthermore, the participants will be subjected to a written phase test on the Hydraulic, Mechanical, Electrical and Installation modules according to the learning objectives (summative evaluation). The Bolt Tightening module does not require a written test, assessment of participant performance is conducted during practical exercises. The written tests can consist of multiple-choice or descriptive answer questions and shall be set at the same taxonomy level as the objective that they are testing.

The multiple-choice test must be conducted in accordance with the following criteria:

1. There shall be at least one question for each lesson in the module with a minimum of 10 questions for each stand-alone module.

There shall be a time limit of 1½ minutes per question.

The tests must be individual.

Global Wind Organisation www.globalwindsafety.org

14 / 262

Technical Training

Basic Technical Training Standard/ V8 2023-05-02

The participants shall not communicate with each other during the test

5. The participants shall not communicate with any persons via email, telephone, Skype (or similar) or social media during the test 6. Where a participant does not understand the meaning of a question or a multiple-choice option, the instructor shall be allowed to help the participant to understand the meaning of the question or the multiple-choice options. The instructor shall not give the participant the correct answers to any test questions.

Participants may use:

Training material

Handouts.

Own notes

Participants may not use:

Mobile phones (except for calculator)

Wearables (e.g. google glasses)

Tablets

Internet browsers

Any other devices similar to those listed above

The multiple-choice test questions cannot be used at any other time during the training in such a way that the participants could recognise that they will be test questions at the end. At least 70% of the questions in the written test must be answered correctly in order to pass the corresponding module. In the event that a participant fails the test, the instructor will have a discussion with the participant in order to find out the reason for this. If the reason was due to the misunderstanding of a question or due to language difficulties, the instructor can mark a question as correct, provided that the participant is able to demonstrate the right level of understanding. This must be properly documented by the instructor and kept together with the tests, control measures, evaluations, etc. Throughout each of the BTT modules, the instructor will use the participant performance assessment form (see annex 1 of the Requirements for Training) to evaluate the participant’s knowledge and skills, with a high focus on evaluating the participant’s safety awareness. The instructor shall keep a participant performance assessment form (or adaptation) for each participant until the completion/evaluation of each BTT training module.

Global Wind Organisation www.globalwindsafety.org

15 / 262

Technical Training

Basic Technical Training Standard/ V8 2023-05-02

The participant performance assessment form (or adaptation) is a final evaluation tool for the instructors to assess participants during practical elements. It allows measurement of the number of violations regarding safety, competency or attitude. The participant performance assessment form shall be used as a progressive evaluation tool to discuss the performance of a participant in guiding them to success. It also serves as supporting documentation if a participant passes or fails the module.

Training providers may adapt the participant performance assessment form to other media.

Training providers must have a documented procedure in place for dealing with participants not meeting the stated learning outcome
