12.4 Participant Prerequisites for the BTT Bolt Tightening Module
Before attending the BTT Bolt Tightening Module participants must first complete the BBT Mechanical Module
12.5 Developing Training Scenarios for this Module
12.5.1 Structure of the Bolt Tightening Module During delivery of the GWO Bolt Tightening Module the instructor shall deliver the training in a practical format whenever possible, achieving a ratio of maximum 30% theoretical training to 70% practical training. The following structure should be followed when delivering the GWO Bolt Tightening Module:
a.
Theoretical section (lessons 1 and 2)
b.
Bolt torquing scenario (lessons 3, 4, 5 and 6)
c.
Bolt Tensioning scenario (lessons 7, 8, 9 and 10)
d. Mechanical handling aids and training review (lessons 11 and 12)
12.5.2 Designing the scenarios This module utilises scenario-based training to train bolt tightening based on the job performance requirements that participants can expect to find in the wind industry. The training provider is therefore required to develop two separate training scenarios: one for torquing and one for tensioning. Each scenario should be created around an example of a bolt tightening task that it typically found in a wind turbine, for example: bolting a tower flange between tower sections 8 and 9 in an onshore wind turbine. The specific torquing and tensioning activities required for each scenario are described in the work instructions provided in annexes 2 and 3. The participants shall use the work instructions and supporting documents to plan, complete and review the specified bolt tightening tasks. Therefore, participants should begin each scenario by reviewing the work instructions to determine what the task entails, what safety and quality considerations they must make, and why these are important. The PDR document is intended to guide the participants through this process. To ensure alignment between the scenario and tasks required by the work instructions, training providers should design each scenario around the work instructions aiming to frame the prescribed tasks within the scenario narrative. Where possible the scenario should require the participants to consider implications of their decisions in relation to safety and quality, for example, the implications of using non-calibrated tools, the safety considerations around reactions arms etc. It is recommended that the participants are grouped into teams and work through the tasks collectively, reflecting the teamwork situations they will encounter when working in the wind industry. However, it is important that the instructor ensure that each participant, individually complete the torquing and tensioning tasks. The purpose of these tasks is for participants to practice adjusting equipment settings and tightening
