    • Assessment of expected production of a deep-sea mining system: An integrated model-based systems engineering and discrete event simulation approach 

      Solheim, Astrid Vamråk; Rauzy, Antoine Bertrand; Brett, Per Olaf; Ellefmo, Steinar Løve; Hatling, Tonje; Helmons, Rudolfus Lambertus Jacobus; Asbjørnslett, Bjørn Egil (Peer reviewed; Journal article, 2023)
      In this paper, model-based systems engineering (MBSE) and discrete event simulation (DES) are combined to assess the performance of an offshore production system at an early stage. Various systems engineering tools are ...

    • Concept study of slurry lifting from deep sea mining in an arctic environment 

      Opstad, Pauline Sundvor (Master thesis, 2022)
      Ved store havdyp finnes det mineral- og metallrike avsetninger. Flere av disse metallene brukes i dagens teknologi for produksjon og lagring av fornybar energi. Videre er det forventet en økning i etterspørselen av metallene ...

    • Early Stage Decisions in Marine Systems Design for Deep-Sea Mining 

      Solheim, Astrid Vamråk; Pettersen, Sigurd Solheim; Agis, Jose Jorge Garcia; Brett, Per Olaf; Asbjørnslett, Bjørn Egil; Erikstad, Stein Ove; Ellefmo, Steinar Løve (Peer reviewed; Journal article, 2022)
      This article studies the prospects for deep seabed mining as a future viable maritime industry, and discuss the commercial, operational, and technical viability of deep seabed mining. By the use of a business development ...

    • Feasibility of Deep-Sea Mining Operation Within Norwegian Jurisdiction 

      Frimanslund, Erik Kristian Thon (Master thesis, 2016)
      Numerous hydrothermal vent sites are discovered along the Arctic Mid-Ocean Ridge (AMOR), stretching some 1,050 km from Jan Mayen to Svalbard, mostly within Norway s economically exclusive zone (EEZ). Associated with these ...

    • First hyperspectral imaging survey of the deep seafloor: High-resolution mapping of manganese nodules 

      Dumke, Ines; Nornes, Stein Melvær; Purser, Autun; Marcon, Yann; Ludvigsen, Martin; Ellefmo, Steinar Løve; Johnsen, Geir; Søreide, Fredrik (Journal article; Peer reviewed, 2018)
      Hyperspectral seafloor surveys using airborne or spaceborne sensors are generally limited to shallow coastal areas, due to the requirement for target illumination by sunlight. Deeper marine environments devoid of sunlight ...
