Various systems engineering tools are ... -
Assessment of Service Vessel Operability In Exposed Aquaculture - An exploratory approach combining vessel response and discrete-event simulation
Stemland, Runar (Master thesis, 2017)The aquaculture industry in Norway is gradually moving towards more exposed locations due to lack of production area and improved production environment. However, large parts of the coast are unavailable to production ... -
Autonomous Low-Emission Kelp Farm Vessel
Myhre, Sigmund Nilsen (Master thesis, 2020)Målet med masteroppgaven er å få en større innsikt i en industri basert på dyrking av tang og tare, og foreslå et fartøydesign som passer inn i denne industrien slik den er i dag. Tare har blitt studert med fokus på ... -
Autonomous Systems Design - An Exploratory Research Study in the Context of Maritime Shipping
Fjelldal, Torgeir (Master thesis, 2018)The maritime shipping industry is experiencing a rapid development towards utilizing autonomous systems to a greater extent. These systems are capable of decision-making and executing actions on behalf of or in cooperation ... -
Blockchain Technology applied in Aquaculture Supply Chains
Rørvik, Odin Søreide (Master thesis, 2022)Blockchain-teknologi har fått gjennomslag i ulike bransjer i løpet av de siste årene, inkludert forsyningskjeder. Blockchain teknologi kan øke effektiviteten i forsyningskjeder ved å koble sammen forsyningskjedesystemer ... -
Blokkjedeteknologi og Potensialet for Implementering i Forskyvningskjeder relatert til Shipping med fokus på Vetting
Rivedal, Håvard Jarl Haugen (Master thesis, 2019)Sjøfartsnæringen står overfor en rask endring i retning av digitalisering der blokkjedeteknologi kan være en viktig del av fremtidige løsninger. Mange maritime forsyningskjeder har et stort forbedringspotensial – noe som ... -
Cargo Stowage Planning in RoRo Shipping: Optimisation Based Naval Architecture
Wathne, Eivind (Master thesis, 2012)Operations research has proven itself to be advantageous in several areas of the industry for many years, but is operations research a good approach to operational maritime planning? Expressions used to calculate the initial ... -
Change in risk picture by going from a conventional sea cage to a submersible cage concept in Norwegian fish farming
Nesje, Jørgen (Master thesis, 2022)Norsk oppdrettsnæring står i dag overfor bærekrafts- og produksjonsutfordringer knyttet til lakselus og arealutnyttelse. I denne forbindelse har ScaleAQ redesignet ei konvensjonell oppdrettsmerd til å kunne senke not posen ... -
Combining design and strategy in offshore shipping
Strøm, Morten Andreas; Rehn, Carl Fredrik; Pettersen, Sigurd Solheim; Erikstad, Stein Ove; Asbjørnslett, Bjørn Egil; Brett, Per Olaf (Chapter, 2018)This paper presents the design-strategy planning (DSP) procedure as a framework that integrates life cycle strategies of a ship into the early stages of the design process. We argue that understanding strategic, tactical, ... -
Competitiveness in construction of offshore fish farms - Assessment of cost and strategic aspects
