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, ... -
Conceptual Design of a Closing Device for the Moonpool on Construction Support Vessels
Opsahl, Jostein (Master thesis, 2015)This thesis is based on an initial investigation of the problem concerning running a vessel with an open moonpool in transit, and how the added resistance can be reduced by installing a closing device in the moonpool ... -
Conceptual Design of Ammonia-fueled Vessels for Deep-sea Shipping
Ness, Anne Sophie Sagbakken (Master thesis, 2021)Nødvendigheten for å redusere klimagassutslipp og behovet for nye reguleringer for karbon nøytral skipsfart øker, og temaet er stadig i fokus. Veien til dekarbonisering inkluderer alternative drivstoffteknologier som bruker ... -
Conceptual Design of Green Ammonia FPSO
Sekandar, Sohrab (Master thesis, 2021)Målet med denne masteravhandlingen er å foreslå et system som kan produsere, lagre og offloade hydrogen ved bruk av fornybar energi. Dette ble gjort ved å utvikle en konseptuell design for problemet basert på metodikk av ... -
Conceptual design of low-emission ships
Lagemann, Benjamin (Doctoral theses at NTNU;2023:186, Doctoral thesis, 2023)Human-induced climate change is one of the significant challenges of our time. In order to help limiting global warming, the International Maritime Organization has set out stepwise greenhouse gas emission reduction ambitions ... -
Conceptual Design of Offshore Energy Storage Systems
Jacobsen, Andreas Ruud (Master thesis, 2021)Mange fornybare energikilder som vind, sol og bølger er intermitterende energikilder. Dette fører ofte til en ubalanse mellom energibehov og produksjon. Den reduserte kommersielle kapasiteten til intermitterende produksjoner ... -
Configuration Based Design, Standardization and Modularization in Offshore Vessel Design
Nickelsen, Marcus Langseth (Master thesis, 2017)Recent low oil prices have caused a downturn of activities in several maritime industries, resulting in increased competition and pushing companies to simultaneously increase their position in the market and reduce cost ... -
Considering Alternative Strategies to Improve Synergies between Shipbroker and Ship Designer in Upstream Shipbuilding Activities
Sjåvåg, Ludvik (Master thesis, 2022)Denne masteroppgaven analyserer hvordan vi kan identifisere en mer effektiv interaksjon mellom skipsmeglere og skipsdesignere i oppstrøms skipsbyggingsaktiviteter. Vi foreslår fire forskningsspørsmål som legger til grunn ... -
Contractual and Economical Consequences of LNG Boil-Off Quality
Gedde, Steffen Tellugen (Master thesis, 2014)The gas evaporating from the Liquefied Natural Gas (LNG), usually called Boil-off Gas (BOG), has previously been out of focus regarding its composition and corresponding heating value. A concentration of the BOG has been ... -
Decision support for future proof ship fuel selection - Moving beyond cost-efficiency
Slotvik, Dorthe Alida Arntzen (Master thesis, 2022)Rundt 80% av verdenshandelen etter volum og over 70% av verdi fraktes til sjøs. Global skipsfart over dype hav sikrer den mest kostnadseffektive transporten av import og eksport av mat og produserte varer og har en betydelig ... -
Decision support for renewal and retrofitting of the fleet of offshore supply vessels to guide the transition towards zero-emission logistics
Olsen, Preben Kristen (Master thesis, 2023)Denne masteroppgaven introduserer en matematisk model som løser det maritime flåte fornyelse problemet med et fokus på utslippskutt av CO_2 for forsyningsskip. Modellens primære mål er å veilede skipsredere om optimal ... -
