About this position
The Norwegian University of Science and Technology (NTNU) is seeking a PhD candidate in the Department of Energy and Process Engineering to investigate the thermal cycling of compact steam cycles, with particular emphasis on once-through steam generators (OTSGs) used in offshore and other space- and weight-constrained applications.
The doctoral project, DUOP – Deeper Understanding of Once-through steam generator Operational Physics, combines advanced numerical modelling with controlled experimental work. The research will examine how transient operation—including start-ups, shutdowns and changing operating conditions—affects OTSG tubing. A central focus is the interaction of thermal stress, fatigue, creep and corrosion, and the mechanisms that can cause damage, reduced reliability and increased maintenance requirements.
The candidate will develop and simulate dynamic process models of compact steam cycles, analyse transient thermal behaviour, and create automated scripting workflows for processing, validating and interpreting measurements from a steam laboratory. The work will also contribute to identifying damage mechanisms and developing a framework for dynamic optimisation of OTSG operation.
The project is a collaboration between NTNU, SINTEF, Cracow University of Technology and industrial partners, supported by the Research Council of Norway and industry. The candidate will work with the Heat-to-Power Laboratory research group and collaborate with national and international researchers, research organisations and industry. The research addresses energy efficiency and emission reduction in offshore power production while also supporting applications in marine and other compact energy systems.
The PhD candidate will be supervised by Professor Lars O. Nord, whose expertise includes thermal power plants, process modelling and simulation. The role also includes doctoral coursework, publication of academic papers, dissemination, co-supervision of master’s students, and participation in conferences or research stays.

What's required
Applicants must meet the admission requirements for NTNU’s Faculty of Engineering Doctoral Programme and hold a relevant master’s degree in Mechanical Engineering, Energy Engineering, Industrial Engineering, Process Engineering or a related field, including a major independent project of at least 30 ECTS equivalent to a master’s thesis. Master’s students may apply, but the degree must be obtained and documented before starting and no later than 2027-08-01. Applicants should have a strong academic record with a master’s average equivalent to B or better on NTNU’s grading scale, or an equivalent foundation; candidates with weaker grades may be considered if they demonstrate exceptional suitability through relevant work experience or peer-reviewed publications. Good oral and written English communication skills, understanding of steam-based power plants and heat exchangers, and a sound foundation in engineering thermodynamics and heat transfer are required. Laboratory experience is required. Preferred qualifications include understanding of process dynamics, experience with design of experiments, and knowledge of thermal stresses and creep-fatigue damage in process equipment. Applicants should be able to work independently and collaboratively, plan and structure their work, handle pressure, show curiosity and motivation, and adapt project plans when needed. The application must include bachelor’s and master’s transcripts and diplomas, CV, master’s thesis or draft, a maximum two-page project outline, a maximum one-page motivation letter, relevant publications or academic works where applicable, certificates if relevant, and contact details for three referees.
How to apply
Submit the application and all required attachments electronically through the Jobbnorge application portal. Include transcripts, diplomas, CV, thesis, project outline, motivation letter, relevant works, certificates if applicable, and three referees’ contact details.
