    • Ship collision analysis with a floating offshore fish farm 

      Yu, Zhaolong; Amdahl, Jørgen; Kristiansen, David (Chapter, 2019)
      Due to limited nearshore areas and great impact to local ecosystems, the aquaculture industry is moving the fish farms from nearshore to more exposed sea regions where waves and current are stronger. Like other offshore ...

    • Ship Collision and Earthquake Analysis of Monopile Offshore Wind Turbines 

      Fjellvikås Solvik, Kristoffer (Master thesis, 2020)
      Offshore vindindustri har opplevd en hurtig utvikling de siste årene. På bare to tiår har turbinene vokst fra å være relativt små til å bli enorme strukturer på flere hundre meter som genererer strøm til tusenvis av ...

    • Ship collisions with floating offshore wind turbines 

      Kvernmo, Andreas Bohinen (Master thesis, 2023)
      Offshore vind er en fornybar energikilde som får mye fokus. Blant fordelene med offshore vind-energi er for eksempel bedre vind-forhold og større muligheter til å øke turbinstørrelsen sammenlignet med landbaserte turbiner. ...

    • A simplified approach for fatigue life prediction of aquaculture nets under waves and currents 

      Slagstad, Martin; Yu, Zhaolong; Amdahl, Jørgen (Peer reviewed; Journal article, 2023)
      With increasing trends to move fish farms to more exposed locations engineers need quick and accurate tools for creating initial design proposals. In this paper, a simplified analytical model for estimating the axial force ...

    • SPAR Type Offshore Wind Turbine Subjected to Ship Impacts 

      Engevik, Anders (Master thesis, 2021)
      Et økende fokus på fornybar energi har ført til en rask utvikling av havvindindustrien de siste årene. For å takle det økende kraftbehovet økes størrelsen av vindturbinene og de flyttes lenger offshore. Det fører til at ...

    • Statistics of thickness and strength of first-year ice along the Northern Sea Route 

      Chai, Wei; Leira, Bernt Johan; Høyland, Knut Vilhelm; Sinsabvarodom, Chana; Yu, Zhaolong (Peer reviewed; Journal article, 2020)
      In this paper, statistics of ice thickness and ice strength of first-year sea ice along the Northern Sea Route (NSR) is studied to provide useful information for the design and operation of Arctic ships. Specifically, ice ...

      Chai, Wei; Leira, Bernt Johan; Høyland, Knut Vilhelm; Sinsabvarodom, Chana; Yu, Zhaolong (Peer reviewed; Journal article, 2020)
      In this paper, statistics of ice thickness and ice strength of first-year sea ice along the Northern Sea Route (NSR) is studied to provide useful information for the design and operation of Arctic ships. Specifically, ice ...

    • Tower design for very large floating wind turbines 

      Fredheim, Rikke Olsen (Master thesis, 2022)
      Flytende havvind kan utnytte vindpotensial på dypere vann og være en verdifull kilde til fornybar og ren energi. For at disse vindturbinene skal bli kostnadseffektive, er det nødvendig å oppskalere. Ved oppskalering kan ...

    • Ultimate and residual strength assessments of intact and collision damaged columns of the Bjørnafjorden floating bridge 

      Yu, Zhaolong; Wang, Xintong; Moan, Torgeir; Amdahl, Jørgen; Sha, Yanyan (Chapter, 2023)
      The Norwegian Public Road Administration (NPRA) has initiated an ambitious project to replace the current ferry crossing solutions with floating bridges over the wide and deep Norwegian fjords. This will substantially ...

    • Uncertainty quantification in the ice-induced local damage assessment of a hull section 

      Kim, Ekaterina; Yu, Zhaolong; Amdahl, Jørgen; Løset, Sveinung (Journal article; Peer reviewed, 2019)
      For the northernmost ocean regions, where the ice is occasionally present, one must design a robust structure that can withstand rare ice events (i.e., a glacial ice impact). Despite existing engineering practice is well ...
