Bachelor- / Master Thesis: Control strategies for optimal load distribution in an offshore crane winch with multiple drivetrains

Webseite Institute for Machine Elements and Systems Engineering

The Institute for Machine Elements and Systems Engineering researches the fundamental structural and tribological behaviour of machine elements and represents it in experimentally validated model descriptions. These models are used to organize and analyse the behaviour of technical systems in terms of functionality, losses, and noise emissions with a focus on drive technology. The developed models also serve as basis for the research and development of methods of Model Based Systems Engineering which are central elements of future industrial product development processes.
Drivetrain failures in the open seas are very costly and time-consuming to fix, and for various offshore systems there exists no models to predict the future state of the system. Therefore, it is important to determine the current state of such systems using simulation models with globally available data as input (motor torque, wave height, carried weight.. etc) in order to predict their lifetime. Models have been created in the institute which calculate the lifetime of AHC-activated offshore winches, however the models still need improvements.


  • Calculation and analysis of the load distribution in 20 drivetrains with different control strategies using already available models
  • Deciding on the best control strategy and optimizing it to produce the most equal distribution of load possible between the drivetrains


  • Independence and reliability in work
  • Interest in multi-body simulation and drivetrain technology
  • Prior knowledge in Simpack, Matlab and Simulink are an advantage

We offer:

  • Possibility to start immediately
  • Intensive mentoring
  • Supportive work climate
  • Research experience for a future career in academics or industry


We look forward to your application by email:
