This is NTNU

At NTNU, creating knowledge for a better world is the vision that unites our 7 000 employees and 40 000 students.

We are looking for dedicated employees to join us.

About the position

We have a vacancy for a 3-year PhD fellowship at the Department of Geoscience and Petroleum (IGP).

The PhD project is part of the SUBPRO center which is a large 8-year research-based innovation program in the field of subsea processing and production. Industrial partners in SUBPRO include Equinor, Lundin, AkerBP, Neptune Energy Norge, Aker Solutions, DNVGL and Kongsberg Digital. For more information about SUBPRO, visit our website:

The main objective of this project is to develop, evaluate and test methods to design optimal subsea systems that include processing equipment. The Norwegian oil and gas industry has the ambition to expand the use of subsea processing in existing and future fields, therefore this topic is important to enable smart and efficient design of such systems. 

This PhD project is an interdisciplinary initiative of the Department of Geoscience and Petroleum and the Department of Chemical Engineering of NTNU. The PhD student is assigned to the Department of Geoscience and Petroleum, but the PhD candidate will spend approximately 50% of the time at the Department of Chemical Engineering. The candidate is supervised by Associate Prof. Stanko from the Department of Geoscience and Petroleum Engineering, and Associate Prof. Jäschke from the Department of Chemical Engineering will act as co-supervisor.

The position reports to the Head of Department

Main duties and responsibilities

  • This PhD project will explore the use of numerical optimization tools to determine layouts of subsea production systems that maximize value (i.e. increase production, reduce expenses) while fulfilling operational and technical constraints.
  • This PhD is a continuation of a previous PostDoctoral project, and will build on and further develop the methods.
  • A particular focus of this project is the development of tools that enable us to find optimal field layouts at an early planning stage. That includes the integration and optimization of system models, and making decisions on whether to deploy decentralized or centralized units, while taking into account flow assurance, reliability and maintenance considerations.

Qualification requirements

The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in engineering or equivalent education with a grade of B or better in terms of NTNU’s grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates 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, postdoctor and research assistant

NTNU is committed to following evaluation criteria for research quality according to The San Francisco Declaration on Research Assessment - DORA.

Other qualifications

  • The candidate should have solid and relevant background in engineering one of the following engineering fields: Chemical, process, control, petroleum, or mechanical engineering.
  • The candidate should possess documented scientific programming skills to solve engineering problems that require modeling.
  • An interest in mathematics and programming is essential, and it is a significant advantage if the candidate has previous documented knowledge on using numerical optimization software.
  • Good written and oral English language skills are essential.

Personal characteristics

  • A high level of personal responsibility and initiative.
  • Work independently as well as part of a team in accordance with the project objectives.

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability, as well as motivation, in terms of the qualification requirements specified in the advertisement.
