A Hydro-Aerodynamic Analysis of a Floating Offshore Wind Turbine to Assist in Floater Selection
(Master thesis, 2022)Ulike typer fundamenter er foreslått til flytende vindturbiner. Hovedtyngden av markedsaktiviteten er "Semi-submersible" fundamenter, hvor hvert konsept har sine fordeler og ulemper med hensyn til designet. Denne oppgaven ... -
A Method for Detecting Near-Misses from AIS Data
(Master thesis, 2019)Konsekvensene av maritime ulykker kan være enorme med hensyn til tap av liv, økonomiske tap og miljøskader. Derfor har forbedring av sikkerheten til sjøs vært et fokus i mange år, og det har vært utført ulike maritime ... -
A Method for Determining the Mode Shapes from a Finite Element Model for Use in a Finite-Mode Vibration Simulation Model
(Master thesis, 2016)In this thesis, a methodology for retrieving mathematical expressions of the mode shapes of a crankshaft based on numerical data yielded by a finite element model is presented and tested. The mode functions should be used ... -
A method for evaluating the potential for retrofitting Wind Assisted Ship Propulsion from a ship owner perspective
(Master thesis, 2022)Skipsfart står for nesten 3% av de totale menneskeskapte utslippene av karbondioksid, og aktører innenfor den maritime næringen er under press for å finne løsninger for å redusere disse utslippene. Et lovende konsept for ... -
A Modular Design Methodology for OSV Accommodation Areas
(Master thesis, 2012)Offshore shipbuilding industry is known for its highly customized products, which are in most cases tailor-made for specific missions. Being a traditionally conservative industry, it follows conventional design practices. ... -
A multi-period fleet retrofit and renewal problem for strategic green corridor planning and emission control in maritime shipping
(Master thesis, 2023)I denne masteroppgaven har vi utviklet en flerperiodisk modell for oppgradering og fornyelse av den maritime flåten. Målet med modellen er å gi verdifull innsikt i strategisk planlegging av grønne korridorer og generelle ... -
A multi-period fleet retrofit and renewal problem for strategic green corridor planning and emission control in maritme shipping
(Master thesis, 2023)I denne masteroppgaven har vi utviklet en flerperiodisk modell for oppgradering og fornyelse av den maritime flåten. Målet med modellen er å gi verdifull innsikt i strategisk planlegging av grønne korridorer og generelle ... -
A New Small-Scale LNG Distribution and Bunkering Facility: - An Approach to Risk Based Design and Verification
(Master thesis, 2013)LNG is the preferred solution to meet environmental requirement and a great market growth is expected within few years. Lack of suitable infrastructure, regulation and bunkering practices poses challenges to the industry, ... -
A Numerical and Experimental Study of a Multi-torus Floating Solar Island Concept
(Master thesis, 2019)En flytedel som skal brukes til plattform for en flytende soløy er testet i modellskala både med og uten solcellepaneldekket. En realistisk skalert membran er brukt for å tilsvare dekket. Begge modellene ble testet både i ... -
A Numerical and Theoretical Study of a Multi-torus Solar Island Concept
(Master thesis, 2020)Teoretiske og numeriske studier er gjennomført for en flytende konstruksjon bestående av sirkulære flytere koblet sammen med elastiske bånd, en såkalt multiflyter. Stukturen er designet for å være et flytende fundament for ... -
A Numerical Study of a Multi-torus Floating Solar Island Concept, with the use of Computer Programming
(Master thesis, 2020)En halvt nedsenket fler-torus modell er implementert numerisk, med hensikt å undersøke responsen til en slik struktur. Den numeriske modellen, bestående av flere sirkulære flytere koblet sammen med elastiske bånd (strekkstag), ... -
A Real Option Approach to Value Flexibility in Ship Design
(Master thesis, 2020)This thesis evaluates whether implementation of flexibility in ship design is a suitable approach to handle an uncertain future. Flexibility exploits opportunities and reduces downside risk. However, a flexible design is ... -
A reliability study of a Deepwater Vertical Xmas Tree with attention to XT retrieval rate
(Master thesis, 2014)The focus of this thesis is towards the subsea Xmas Tree (XT) system. The XT is recognized by the industry as an overall reliable configuration, but as in all development projects, it is a constant battle to optimize the ... -
A Sensitivity Study of Ice Resistance Prediction Methods Using a Developed Bow Shape Modelling Tool
(Master thesis, 2015)The shipping in ice-covered waters increases the need of knowledge and understanding about physical effects of the icebreaking process during the ship-ice interaction. The shape of the ship bow will affect the ice resistance ... -
A Simulation Study of Installation Concepts for Floating Offshore Wind Farms
(Master thesis, 2020)Today, land based wind energy development projects are creating political controversy. An alternative for Norway could be floating offshore wind. We have the areas, and we have the technologies. A challenge is that this ... -
