    • Back to the Future: Rebirth of Pure Wind Propelled Ships 

      Haugbråten, Mathias Frøiland; Caspari, Håkon (Master thesis, 2023)
      For å møte målene presentert i Parisavtalen og begrense global oppvarming må den maritime sektoren gjennomføre store endinger for å redusere utslipp. Overgangen fra petroleumsbaserte drivstoff til nye løsninger er en måte ...

    • Back to the Future: Rebirth of Pure Wind Propelled Ships 

      Haugbråten, Mathias Frøiland; Caspari. Håkon (Master thesis, 2023)

    • Conceptual design of low-emission ships 

      Lagemann, Benjamin (Doctoral theses at NTNU;2023:186, Doctoral thesis, 2023)
      Human-induced climate change is one of the significant challenges of our time. In order to help limiting global warming, the International Maritime Organization has set out stepwise greenhouse gas emission reduction ambitions ...

    • Design methodology state-of-the-art report 

      Erikstad, Stein Ove; Lagemann, Benjamin (Research report, 2022)
      Marine systems design methodology is continuously evolving. On a strategic level, we have seen four major evolutionary tracks emerging from the sequential, iterative process captured in the classical design spiral. One is ...

    • Maritime fleet composition under future greenhouse gas emission restrictions and uncertain fuel prices 

      Loennechen, Olav; Fagerholt, Kjetil; Lagemann, Benjamin; Stålhane, Magnus (Peer reviewed; Journal article, 2024)
      This paper studies the maritime fleet composition problem with uncertain future fuel and carbon prices under the restriction of complying with future greenhouse gas (GHG) emission restrictions. We propose a two-stage ...

    • Modular Conceptual Synthesis of Low-Emission Ships 

      Lagemann, Benjamin; Erikstad, Stein Ove (Chapter, 2020)
      With the ambition of lowering emission from shipping, today’s ship designers face both the freedom and challenge to select from a large set of different ship system concepts during the conceptual design stage. In order to ...

    • Optimal maritime fleet composition under future greenhouse gas emissions restrictions and uncertain fuel prices 

      Loennechen, Olav (Master thesis, 2023)
      Shippingindustrien er en stor bidragsyter til globale klimagassutslipp. En viktig faktor for industrien sine store utslipp er dens avhengighet av tung fyringsolje med høyt karboninnhold. For å redusere utslippene, bør ...

    • Optimal Ship Fuel Selection under Life Cycle Uncertainty 

      Zwaginga, Jesper; Lagemann, Benjamin; Erikstad, Stein Ove; Pruyn, Jeroen (Journal article, 2024)
      Shipowners need to prepare for low-emission fuel alternatives to meet the IMO 2050 goals. This is a complex problem due to conflicting objectives and a high degree of uncertainty. To help navigate this problem, this paper ...

    • Optimal ship lifetime fuel and power system selection 

      Lagemann, Benjamin; Lindstad, Elizabeth; Fagerholt, Kjetil; Rialland, Agathe Isabelle; Erikstad, Stein Ove (Journal article; Peer reviewed, 2021)

    • Optimal ship lifetime fuel and power system selection under uncertainty 

      Lagemann, Benjamin; Lagouvardou, Sotiria; Lindstad, Elizabeth; Kjetil, Fagerholt; Psaraftis, Harilaos; Erikstad, Stein Ove (Peer reviewed; Journal article, 2023)
      Ship designers face increasing pressure to comply with global emission reduction ambitions. Alternative fuels, potentially derived from bio-feedstock or renewable electricity, provide promising solutions to this problem. ...

    • Reduction of maritime GHG emissions and the potential role of E-fuels 

      Lindstad, Elizabeth; Lagemann, Benjamin; Rialland, Agathe Isabelle; Gamlem, Gunnar Malm; Valland, Anders (Peer reviewed; Journal article, 2021)
      Maritime transport accounts for around 3% of global anthropogenic Greenhouse gas (GHG) emissions (Well-to-Wake) and these emissions must be reduced with at least 50% in absolute values by 2050, to contribute to the ambitions ...

    • System alternatives for modular, zero-emission high-speed ferries 

      Lagemann, Benjamin; Seidenberg, Tobias; Jürgenhake, Christoph; Erikstad, Stein Ove; Dumitrescu, Roman (SNAME International Conference on Fast Sea Transportation;, Chapter, 2021)
      Low emission requirements exert increasing influence upon ship design. The large variety of technological options makes selecting systems during the conceptual design phase a difficult endeavor. To compare different ...

    • Understanding Agility as a Parameter for Fuel-Flexible Ships 

      Lagemann, Benjamin; Erikstad, Stein Ove; Brett, Per Olaf; Garcia Agis, Jose Jorge (SNAME 14th International Marine Design Conference;, Research report, 2022)
      With the need for lower-emission maritime transport solutions, shipowners and designers face uncertainty when it comes to the selection of fuel today and in the future. The effects of this uncertainty can be mitigated to ...
