About the job

The Department of Marine Technology is looking for a PhD Candidate in probabilistic lifetime assessment of nylon mooring lines for offshore renewable energy. For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.

This position will focus on application of probabilistic methods and structural reliability analysis to nylon mooring lines for offshore renewable energy with main focus on floating wind turbines. The objective is to identify the lifetime probability of failure, also including studies of different mooring systems. This will also allow quantification of how different variables and design parameters will influence the system performance and how they interact with each other. One of the gaps preventing such analyses at present is the quantification of uncertainties in nylon material and rope properties and how they change during the lifetime. The probabilistic approach also requires application of load effect calculation tools which can correctly represent the creep and stiffness properties of nylon ropes.

The PhD work will accordingly need to address the following topics: (i) Quantification of uncertainties associated with nylon rope properties based on new test data, including time-varying degradation effects (ii) Identification of relevant failure modes for both single nylon mooring lines and for different mooring configurations. (iii) Statistical models of mooring line load effects both in relation to extreme values and stress cycle distributions (iv) Dedicated methods and tools for reliability assessment which can account for long-term behavior of nylon mooring lines.

A basic hypothesis is that long-term degradation effects can be estimated based on existing knowledge, new laboratory and field testing without accelerated test programs, also combined with theoretical/numerical modelling. Accordingly, the work of the PhD-candidate should strive to confirm the validity of this basic hypothesis.

Your immediate leaders are your Main Supervisor and the Head of the Department.


Duties of the position
  • conduct original, cutting-edge research, including critical literature review to identify the state-of-the-art and research gaps, designing research projects and methodologies, and generating, collecting, and analysing data
  • publish findings in top-tier journals and present at international conferences
  • collaborate actively within the project team and with external partners
  • engage in professional development through attending seminars, lectures, and workshops as well as networking (all supported financially and professionally)

Required selection criteria
  • professionally relevant background in Marine, Mechanical, Aerospace or Structural Engineering, or a related discipline
  • education must correspond to a five-year Norwegian degree program, where 120 credits are obtained at master's level
  • strong academic background from your previous studies and an average grade from the master's degree program, or equivalent education, which is equal to B or better compared with NTNU's grading scale . If you do not have letter grades from previous studies, you must have an equally good academic basis. If you have a weaker grade background, you may be assessed if you can document that you are particularly suitable for a PhD education
  • master's students can apply, but the master's degree must be obtained and documented by August 2024
  • meet the requirements for admission to the faculty's doctoral program (https://www.ntnu.edu/studies/phiv )
  • good skills in English both written and spoken
  • proficiency in finite element methods and probabilistic modelling
  • strong knowledge in continuum and damage mechanics

The appointment is to be made in accordance with Regulations on terms of employment for positions such as postdoctoral fellow, Phd candidate, research assistant and specialist candidate and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant 


Preferred selection criteria
  • experimental experience and in strain measurement
  • knowledge in composite materials
  • programming skills in MATLAB and Python
  • experience in statistical modelling and structural reliability analysis

Personal characteristics
  •     self-motivated with intellectual curiosity
  •     strong critical thinking and problem-solving skills
  •     attention to detail
  •     excellent communication, collaboration, and networking abilities
  •     ability to work independently and as part of a team
