About
In 2022 I started my PhD under the supervision of Ingrid Bouwer Utne and Børge Rokseth at the Department of Marine Technology. My work is part of the ZeroKyst project (https://zerokyst.no/en/) to facilitate decarbonization in the Norwegian coastal fisheries. My focus is on safety and sustainability evaluation of zero-emission fishing vessels.
I hold a Master’s degree from NTNU's Department of Marine Technology with specialization in Marine Systems Design (thesis title: Evaluating the Potential and Viability of Wind-Assisted Ship Propulsion (WASP) for Vessels in the Norwegian Aquaculture Industry) and a Bachelor’s degree in Naval Architecture and Maritime Technology from UAS Kiel in Germany (thesis title: Comparison of Power Management and Propulsion Systems for a 80-Meter Mega Yacht to increase Energy Efficiency).
In between my bachelor’s and master’s studies, I worked for one year as a project engineer in the R&D department at Nobiskrug shipyard in Germany with research topics in energy efficiency, alternative energy sources, and hybrid propulsion systems for super yachts.
As a passionate sailor, I am deeply connected to the Oceans and during two Atlantic crossings, I could experience the effects of humanity on the oceans and climate first-hand. This motivates me to further explore the opportunities and challenges for a green transition in shipping from an engineering and systems perspective.

Safety and Sustainability Evaluation of zero-emission Fishing Vessels
«Klimagassutslipp fra sjømatnæringen i Norge er ute av kontroll: Ingen vet hva de reelle utslippene er, men vi kan fastslå at de øker raskt …»[1] writes Erik Ianssen, project leader in the ZeroKyst project in his report about greenhouse gas emissions from the seafood industry. He makes it clear that everyone, industry, authorities, and science, must work together to achieve the set emission reduction targets. Ianssen concludes his report with «Det haster.»1
To contribute to solving the complex question of how emissions can be reduced, I have set up two main research questions:
How does the safety of a ship change as a result of zero-emission propulsion?
- The focus here is on identifying risks posed by the conversion to zero-emission using various technologies. The goal is to provide guidance on how to deal with these new risks in future projects.
Is the new system more sustainable?
- It is often discussed whether alternative propulsion methods really reduce emissions or whether these emissions are only shifted to other areas. The aim is to assess the environmental impact of different decarbonisation technologies from a system and life cycle perspective. The result should be sustainability indicators for several systems as decision support for future new build and refit projects.
With my work and the indicators that I intend to develop, I will provide guidance to the industry on how to evaluate new propulsion systems. The assessments can help to find the best solution for each individual use case
