    • 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 ...

    • Deep Sea Mining: Towards Conceptual Design for Underwater Transportation 

      Solheim, Astrid Vamråk; Lesage, Maxime; Asbjørnslett, Bjørn Egil; Erikstad, Stein Ove (Chapter, 2020)
      This paper presents the first steps towards conceptual design for the underwater transportation of minerals from seabed to shore for deep sea mining (DSM). The methodology is based on conceptual design using a systematic ...

    • 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 ...

    • Exploring the performance of conceptual offshore production systems for deep-sea mining 

      Solheim, Astrid Vamråk (Doctoral theses at NTNU;2023:176, Doctoral thesis, 2023)
      Offshore production systems are required to support the extraction, lifting, and shipment of deep-seabed minerals. Increasing the knowledge about such novel systems is important to identify constrained parameters and ...

    • Open Hatch Carriers - Future Vessel Designs & Operations 

      Lindstad, Elizabeth; Alterskjær, Sverre Anders; Sandaas, Inge; Solheim, Astrid Vamråk; Vigsnes, Joakim Tveiten (Journal article; Peer reviewed, 2022)
      The development of Open hatch carriers (OHC) dates back to the early 1960s linked to transport of newsprint from the paper mills along the coast of British Columbia (Canada) to the news-printers in San Francisco and Los ...

    • System-based ship design of a deep-sea mining vessel 

      Solheim, Astrid Vamråk; Groven, Brage R.; Røsbjørgen, Jan Magnus; Wigdahl, Aron; Aanondsen, Svein Aanond; Brett, Per Olaf; Asbjørnslett, Bjørn Egil (Peer reviewed; Journal article, 2024)
      This paper applies the system-based ship design (SBSD) method to the conceptual design of a deep-sea mining vessel. The anticipated mine site is situated on the Norwegian extended continental shelf, where three production ...

    • Technology Transfer in Novel Ship Design: A Deep Seabed Mining Study 

      Solheim, Astrid Vamråk; Brett, Per Olaf; Garcia Agis, Jose Jorge; Erikstad, Stein Ove; Asbjørnslett, Bjørn Egil (Journal article, 2022)
      Designing new ships for new purposes, in this case deep seabed mining, without using proper selected reference vessels, if available, is challenging. In this paper, we show that the vessel features of a future deep seabed ...

    • Transportation for deep sea mining using underwater vehicle: Conceptual design using a systematic approach 

      Solheim, Astrid Vamråk (Master thesis, 2019)
      Hensikten med denne oppgaven er å foreslå designløsning (er) på konseptuelt nivå for undervannstransport av malm fra havbunn til havn for gruvedrift. Essensen av dyphavs gruvedrift er å utvinne mineraler fra en marin ...

    • What is a ship design firm, really? 

      Lagemann, Benjamin; Lunnan, Randi; Brett, Per Olaf; Garcia Agis, Jose Jorge; Solheim, Astrid Vamråk; Erikstad, Stein Ove (Journal article; Peer reviewed, 2024)
      Ship design is a creative process serving a defined objective. This is normally an iterative process with the design being corrected and adjusted many times until it satisfies this objective. Ship design is taking place ...
