Siemens has recently put a team of 8 maintenance engineers from its Energy ADGT (Aero Derivative Gas Turbine) division through a pilot training course at James Walker RotaBolt in the U.K. The 8 engineers are part of a 350 strong global team who are responsible for the maintenance of 200 Rolls-Royce Aero derivative Gas Turbine units that have RotaBolt fasteners fitted to the fuel systems that supply the turbines.
In time, Siemens-ADGT is planning to train its entire global workforce of maintenance engineers in the application of RotaBolt technology. “We have been using RotaBolt fasteners for the last ten years because we need to ensure correct levels of bolt tension through our interface pipe connections on our fuel delivery systems,” commented Tom Doyle, Training and Competency Manager with Siemens-ADGT, “this course is all about ensuring our engineers have a thorough understanding of how and why the technology works.”
As part of their programme of continuous improvement in training and competencies, Siemens has increased its requirement of practical experience alongside theoretical training. The visit to the RotaBolt production facility enabled the team to not only understand the theory of RotaBolt technology, but to also see how the fasteners are produced and gain first-hand experience of their assembly and testing.
Every RotaBolt fastener made is individually calibrated and then 100% load tested and the team were able to participate in the calibration process, as well as understanding correct tightening procedures.
Rod Corbett from James Walker RotaBolt added, “We still find that although many engineers understand that our technology works, there is often quite widespread misunderstanding as to why, and the basic principles behind it. We are delighted to support any initiatives that help spread understanding about the benefits of measuring bolt tension.”
The Rolls Royce turbines which have the fasteners fitted to their off-engine fuel systems are located in Chile, Australia, Russia, Middle East, United States and the U.K. and are used in both the Oil and Gas and Power generation industries.
