PhD candidate in the field of buckling and collapse mechanics of offshore wind turbines at NORWEGIAN UNIVERSITY OF SCIENCE & TECHNOLOGY – NTNU

About the job

We have a vacancy for a PhD position at the Department of Marine Technology in the field of mechanics of buckling and collapse of offshore wind turbines under accidental loads, e.g. collisions with ships, earthquakes, strong gusts of wind, extreme wave impacts, etc.

For a doctoral position, the objective is a complete doctoral training until obtaining a doctorate.

Offshore wind turbines are at the forefront of the green transition from conventional fossil fuel to clean, decarbonizing energy. The number of offshore wind turbine installations is expected to grow at record speed over the next few decades. Offshore wind turbines are susceptible to extreme conditions during their lifetime, such as accidental collisions with ships, earthquakes, strong gusts of wind, extreme wave impacts, etc. Such accidental loads can lead to undesirable consequences such as structural damage, flooding and, in the worst case, result in platform collapse, capsizing and death. It is therefore the objective of this project to study the mechanics of buckling and collapse of offshore wind turbines under accidental loads and to propose rational design procedures against such accidental loads.

The work of this PhD position focuses primarily on structural mechanics, but will also contain interdisciplinary work, including hydrodynamics and aerodynamics, where the candidate will be required to collaborate with colleagues from different disciplines.

You will report to the department chair and your supervising professor.

Job duties

  • Numerical modeling of fixed and floating offshore wind turbines under accidental actions using non-linear finite element methods with proper consideration of possible ground conditions, hydrodynamic loads and aerodynamic loads where applicable
  • Understand how the turbine tower vibrates under accidental actions and perform subsequence analysis and local buckling design of the tapered cylindrical shell.
  • Perform analytical work related to energy absorption during an impact event and tower vibration under impulsive disturbances.
  • Make recommendations for the design of offshore wind turbines against accidental loads.
  • Conduct academic essays and publish project results in recognized peer-reviewed journals and international conferences

Selection criteria required

  • You must have relevant professional experience in one or more of the following fields: marine engineering, civil engineering, structural engineering, mechanical engineering or equivalent.
  • Your education must correspond to a five-year Norwegian study program, where 120 credits are obtained at master’s level
  • You must have a strong academic background from your previous studies and an average grade from the Master’s program, or an equivalent background, equal to or better than B on the NTNU grading scale. If you don’t have letter grades from previous studies, you must have an equally good academic foundation. If you have a lower academic level, you can be assessed if you can document that you are particularly suitable for doctoral training.
  • You must meet the conditions for admission to the doctoral program of the faculty (
  • Good English skills (written and oral)
  • Good programming skills in Matlab, C, Python or similar

The appointment is to be made in accordance with the regulations in force concerning State Employees and Officials and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for the appointment as PhD, post doctor and research assistant

Preferred Selection Criteria

  • Good knowledge and skills in finite element modeling and performing nonlinear finite element analysis
  • Solid background in mathematics and mechanics, and well prepared to solve physical problems with analytical methods
  • Knowledge of fluid mechanics and wave hydrodynamics is considered an asset.

Personal characteristics

  • Motivated and driven by curiosity
  • Ability to work independently and in a team
  • Ability to carry out interdisciplinary work
  • Critical thinker both mathematically and physically
  • Good presentation skills
