Contract Type
Full Time

About the position

We have a vacancy for a PhD candidate at the Department of Marine Technology. 

The Upscale project, led by IFE, is a collaboration among universities, research institutes, and industry partners, and will study the design of very large (20MW+) floating wind turbines.

The PhD project focuses on the design and analysis of the substructure, incorporating aspects such as hydroelasticity, the effects of control systems, and mooring design.

You will report to Supervising Professor.

Duties of the position

Very large (20MW+) floating wind turbines (FWTs) are expected to be complex, highly elastic structures, and there are strong interactions between the aerodynamic loads, wind turbine controller, hydrodynamic loads, and structural responses. The PhD project focuses primarily on the substructure, but requires multidisciplinary knowledge across hydrodynamics, aerodynamics, control theory, and structural dynamics. The tasks will include, for example:

  • Concept choice for the FWT for a given location
  • Preliminary sizing of the hull, and identification of important natural frequencies
  • Development of linear and second order hydroelastic simulation tools in order to include hull flexibility within time domain models
  • Investigation of damping technologies for reducing fatigue loads in the substructure
  • Investigation of advanced mooring systems for very large FWTs.

Required selection criteria

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is that you have completed a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in marine technology, marine civil engineering, structural dynamics, or equivalent education with a grade of B or better in terms of NTNU’s grading scale. If you do not have letter grades from previous studies, you must have an equally good academic foundation. If you are unable to meet these criteria you may be considered only if you can document that you are particularly suitable for education leading to a PhD degree.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, post doctor and research assistant.

  • Strong theoretical background in structural dynamics
  • Programming skills in MATLAB, C, Python, or similar
  • Excellent command of the English language, including academic writing

Preferred selection criteria

  • Strong theoretical background in marine hydrodynamics
  • Experience with wind turbine simulations or design

Personal characteristics

  • Strong analytical skills
  • Enthusiastic, able to adapt and learn
  • Highly motivated and scientifically curious
  • Positive attitude and interested in teamwork
  • Ability to take initiative and to work independently

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability.
