    • Addressing the Coast Guard Fleet Mix Problem From a Value-Centric Perspective 

      Buland, Marius Oddmund (Master thesis, 2017)
      The decision to acquire a fleet of coast guard vessels is typically irreversible and of longterm impact. Once vessels are bought and built, they typically remain within the fleet for a few decades. This emphasizes the ...

    • Designing Resilience into Service Supply Chains: A Conceptual Methodology 

      Pettersen, Sigurd Solheim; Asbjørnslett, Bjørn Egil; Erikstad, Stein Ove (Chapter, 2018)
      This chapter presents a methodology for designing resilient service supply chains. The approach combines system design methods with methods from risk assessment. Service supply chains consist of multiple assets, cooperating ...

    • Designing resilient fleets for maritime emergency response operations 

      Pettersen, Sigurd Solheim; Asbjørnslett, Bjørn Egil (Chapter, 2016)
      In this paper, we investigate the problem of designing resilience into a fleet for maritime emergency response operations. A broad set of events can trigger emergency response, requiring that a fleet of vessels for this ...

    • 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 ...

    • Evaluating fleet effectiveness in tactical emergency response missions using a maximal covering formulation 

      Pettersen, Sigurd Solheim; Fagerholt, Kjetil; Asbjørnslett, Bjørn Egil (Peer reviewed; Journal article, 2019)
      This paper concerns the evaluation of alternative fleets of advanced special vessels, like coast guard or emergency response and rescue vessels. The paper proposes a mathematical programming formulation of the Fleet ...

    • Evaluation of new design concept of submerged fish farm 

      Glestad, Ingrid Elisabeth (Master thesis, 2019)
      Akvakulturen opplever en rask utvikling mot nye design av oppdrettsanlegg som kan plasseres i mer eksponerte farvann og tåle et tøffere klima. De nye designene for akvakulturen tar sikte på å løse problemene rundt lakselusen, ...

    • Exploiting latent functional capabilities for resilience in design of engineering systems 

      Pettersen, Sigurd Solheim; Erikstad, Stein Ove; Asbjørnslett, Bjørn Egil (Journal article; Peer reviewed, 2017)
      In this paper, we address latent functional capabilities, capabilities that were neither intended nor recognized in the design process. We propose that latent capabilities can improve the resilience of engineering systems, ...
