PhD in Industrial Asset Management: Predictive Maintenance for Wind Blade Erosion
The University of Stavanger invites applicants for a PhD Fellowship in Industrial Asset Management at the Faculty of Science and Technology, Department of Science and Technology. The position is vacant from August 2023.
This is a trainee position that will give promising researchers an opportunity for academic development through a PhD education leading to a doctoral degree.
The hired candidate will be admitted to the PhD program in Science and Technology. The education includes relevant courses amounting to about six months of study, a dissertation based on independent research, participation in national and international research environments, relevant academic communication, a trial lecture and public defence.

The appointment is for three years with research duties exclusively.Research topic
The PhD Fellow will be affiliated with the following project: Predictive Maintenance for Wind Turbine Blade Erosion .
The wind energy industry in and around the North Sea is rapidly evolving where bigger and more innovative wind turbine models are installed. Globally, blade failures are responsible for 10% to 24% of total failures, and around 131 to 556 downtime hours per wind turbine. Therefore, the maintenance expenses and production losses due to such high frequent failures and long downtime events, are significant issues for the industry. Leading-edge erosion on wind turbine blades is a major cause of these failure and maintenance events, besides the reduced power output (due to a reduction in lifting coefficient). Leading-edge erosion is caused by the repeated bombardment of the wind turbine blade, primarily by raindrops and particulate matter, such as snow, hail, salt, and Ultraviolet (UV) radiation. A general trend is observed where the blade erosion failure rate increases proportionally with the turbines rating, as the blade is larger and the tip speed is higher. Manual blade inspection (once a year) is a common practice to ensure the blade s health and plan for blade repair operations in good time, to avoid production performance losses, and keep the repair cost minimal. However, blade inspection operations are also challenging, costly, less informative (once a year), and enforce the development toward monitoring (especially online) or unmanned inspection operations (using drones). Blade erosion might generate several symptoms, e.g. vibration, acoustic, mass loss, and impact energy, which might help to diagnose the severity level and further to predict the remaining useful time.
Therefore, the purpose of this project is to study the vibration and acoustic behaviour of eroded blades at several severity levels in order to remotely monitor and build a predictive maintenance program.
This project aims to answer the following research questions: (1) How does blade erosion fault evolve over time and which symptoms can be measured over time? (2) What is the most effective experimental set-up to accelerate blade erosion naturally or artificially and capable to mimic real erosion evolution? (3) What are the most effective detection and diagnosis technique(s) to detect the blade erosion severity level? and (4) What is the most effective prognosis technique to estimate the remaining useful time based on real-time measurements?
The project requires a high level of project management skills as it will be strongly connected to three local industrial partners.Qualification requirements
We are looking for applicants with a strong academic background who have completed a five-year master degree (3+2) within maintenance engineering, mechanical engineering, material science, mechatronics engineering or industrial engineering, preferably acquired recently; or who possess corresponding qualifications that could provide a basis for successfully completing a doctorate.
It is an advantage if your have experience within mechanical modelling and condition monitoring. Monitoring is an important part of the project to discover symptoms in eroded blades at different levels. It is also an advantage if you have background within predictive analyses, used to classify faults and the level of severity, and to predict residual use time for the assets, will be preferred.
To be eligible for admission to the doctoral programmes at the University of Stavanger both the grade for your master s thesis and the weighted average grade of your master s degree must individually be equivalent to or better than a B grade. If you finish your education (masters degree) in the spring of 2023, you are also welcome to apply.
Applicants with an education from an institution with a different grade scale than A-F, and/or with other types of credits than sp/ECTS, must attach a confirmed conversion scale that shows how the grades can be compared with the Norwegian A-F scale and a Diploma Supplement or similar that explains the scope of the subjects that are included in the education. You can use these conversion scales to calculate your points for admission.
