Post Doctor position on Design and optimization of Medium Voltage DC grids for supplying power to underwater vehicles” 

The Faculty of Information Technology and Electrical Engineering (IE), at the Norwegian University of Science and Technology (NTNU) has a vacancy for a 100% position (2 years) as a Post Doctor researcher at the Department of Electric Power Engineering (IEL), The described Post Doctor position is part of a research project on “High-Efficiency all-electric DC supply systems for subsea work-class remotely operated vehicles (HEROVs)”. HEROVs is a joint research collaboration between NTNU and two industrial partners: Ingeteam Power Technology S.A. based in Bilbao, Spain, and Argus Remote Systems A.S. based in Bergen, Norway.

Information about the Department

Currently there are 12 Professors, 7 Associate Professors and 4 Lecturers at the Department of Electric Power Engineering. In addition, there are 4 Adjunct Professors, 2 Adjunct Associate Professors, 9 Postdoctoral researchers, 3 Researchers, about 35 PhD students, and 15 technical/administrative staff. Research activities are organized under two research groups: Power Systems Group and Power Technology Group. The department has a good laboratory infrastructure for research and education, as well as a mechanical workshop, supported by a technical staff of 10 persons.

Work description

The increasing growth of offshore and subsea activities in deep and ultra-deep waters, underpinned by the steep increase in offshore wind farms deployments, oil and gas processes progressively moved to the seafloor and other niche applications such as deep sea mining, military and forensics, require high number of underwater vehicles. They have high power demands and must be capable of operating under extreme conditions. The focus of the HEROVs project is on work-class Remotely Operated Vehicles (WROVs), which have power ratings exceeding 200 kVA and operating in water depths up to 11000 m. The WROV industry is presently transitioning to all-electric solutions enabling higher reliability, reduced weight and improved efficiency and controllability, but this poses challenging requirements to their subsea power supply system.

The goal of the project is to design, analyze and experimentally verify high-efficiency all-electric DC power distribution systems for deep underwater vehicles based on medium-voltage DC (MVDC) technology. In particular, within HEROVs, a post doc researcher will investigate the design and optimization of the MVDC distribution grid, while a closely related PhD project will focus on the design and optimization of power electronic converters employed on WROVs.

Within this context, there is one vacant Post Doctor position available at NTNU within the field of Design and optimization of Medium Voltage DC grids for supplying power to underwater vehicles.

The successful Post Doctor candidate is expected to identify optimal configurations for the DC power distribution grid used to supply power to the underwater loads by applying multi-objective optimization techniques. This shall result in the development of a tool to identify the best configuration from multiple standpoints (e.g. in terms of losses, weight, cost, etc.) and given input conditions. The design criteria should take into account the technical choices (e.g. converter design) made for the WROVs and the support vessel. Hence, the Post Doctor candidate will need to work in close synergy with other researchers contributing to the project. The final result will be the small-scale laboratory testing of the selected grid system using Power Hardware-in-the-Loop techniques, in collaboration with the industrial partner, Ingeteam.

Formal requirements and qualifications

Applicants must hold a PhD degree within electrical engineering and experience with MVDC application and/or a good understanding of multi-objective optimization techniques applied to electrical grids. A strong background in stability and control of power electronic systems will be merited and experience with Hardware-in-the-Loop testing will be an advantage.

Excellent analytical and communication skills are required.

The candidates must have excellent collaboration skills as well as an ability to work independently.

Applicants currently enrolled in a PhD programme who expect to pursue the PhD degree before the date of appointment must forward documentation for the date of their final exam.

Applicants are required to submit a one-page research proposal within the proposed research area.

Language requirements

Applicants must provide evidence of good English language skills, written and spoken. The following tests can be used as such documentation: TOEFL, IELTS or Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE). Minimum scores are:

  • TOEFL: 600 (paper-based test), 92 (Internet-based test)
  • IELTS: 6.5, with no section lower than 5.5 (only Academic IELTS test accepted)
  • CAE/CPE: grade B or A.

Salary conditions:

The position is in code 1017 Research fellow, salary grade 50–62 in the Norwegian State salary scale, gross NOK 430 200 – 529 500 per year, depending on qualifications. A deduction of 2 % is made as a statutory contribution to the Norwegian Public Service Pension Fund.


We can offer:

  • an informal and friendly workplace with dedicated colleagues
