Batteries for marine applications
(Master thesis, 2013)The significant reduction in environmental emissions stated by the new IMO legislation, which specifies an amount of sulphur in fuels below 5% for 2020 and a NOx limit with an 80% reduction respect to the actual IMO limit ... -
Planlegging av Arktiske operasjoner: Fiskeflåtens og Polarkodens påvirkning av Arktiske operasjoner
(Master thesis, 2013)Med krympingen av den Arktiske isen, utvides mulighetene for aktivitet i området. Fiskefartøy har vært i Arktis lenge, og ved at området er isfritt lengre, åpnes det for en lengre driftsperiode i nordområdene. Denne fordelen ... -
Stress influence of offshore wind farms on the reproduction of the viviparous eelpout (Zoarces viviparus)
(Master thesis, 2013)Okende behov for fornybar energi har skapt en økning av installasjoner for fornybar marin energi. Disse installasjonene varierer fra bølge- og tidevannskraft til offshore vindkraft. Påvirkning av offshore vindkraft på ... -
Strategies and measures for reducing maritime CO₂ emissions
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:201, Doctoral thesis, 2013)CO2 emissions from maritime transport represent 3.3% of global anthropogenic CO2 emissions. These emissions are forecasted to increase by 150% - 250% up to 2050, due to increased freight volumes (Buhaug et al., 2009). ... -
Simulation of viscous Flow around a circular Cylinder with STAR-CCM+
(Master thesis, 2013)In this thesis, three-dimensional modelling of the flow around a circular cylinder isaccomplished. Two cases are considered. The first (Case 1) is a cylinder in steady,uniform current subjected to Reynolds number 3900. The ... -
Experimental Study on the Hydrodynamic Forces acting on Objects in a Moonpool
(Master thesis, 2013)This master thesis describes and discusses an experimental study on the hydrodynamic forces acting on objects in a moonpool, carried out at MARINTEK in 2013. The experiments were done using a simplified 2-dimensional ... -
On a Decision-support System for Early Warning of the Risk of, and Growth-rate of, Icing on a Ship?s Superstructure
(Master thesis, 2013)Arctic regions represent a challenging environment for marine operations and icing of the superstructure on ships and rigs constitute one of these challenges. Icing on ships and structures can either be generated from ... -
Steel weight optimisation with respect to stiffener spacing and plate thickness of mid ship structure for cargo vessels
(Master thesis, 2013)When building a ship, the weight and cost are important factors. By reducing weight there will be more cargo capacity which ensures the income for the ship owner. On the other hand, creating light weight structure often ... -
Vortex Induced Fatigue Damage of a Steel Catenary Riser near the Touchdown Point
(Master thesis, 2013)In this thesis, the fatigue damage of a steel catenary riser was investigated, especially in the vicinity of the touchdown point.The steel catenary riser is a promising riser solution due to its simplicity and low cost. ... -
Reliability-Centered Maintenance Methodology: Case Study and Improvements
(Master thesis, 2013)CONCLUSIONThe RCM is learned by applying to specific system and during the work several difficulties are discovered. As a solution to these problems there are suggested to use methods such as Concurrent Design and project ... -
