Software-to-Software Comparison of End-Anchored Floating Bridge Global Analysis
(Peer reviewed; Journal article, 2020)Several computer programs exist to handle general multipurpose offshore structural analysis of slender structures subjected to wave loading, although they have not been developed with the specific purpose of floating bridge ... -
Some aspects of sea-air CO2 flux estimation from long-term mean wind speed statistics
(Journal article; Peer reviewed, 2018)This paper addresses the estimation of the sea-air CO2 flux based on a commonly used bulk formula in terms of the mean wind speed at the 10-meter (10-m) elevation above the sea surface. Results are exemplified by using ... -
Some probabilistic properties of deep water wave steepness
(Journal article; Peer reviewed, 2017)This paper provides some probabilistic properties of the deep water wave steepness and the spectral wave steepness by using distributions based on data from the Norwegian continental shelf. Here the average statistical ... -
Some relationships between build strategy and shipbuilding time in European shipbuilding
(Peer reviewed; Journal article, 2023)The build strategy of a ship specifies what is to be produced how, when, where and with what resources. Although it has been emphasised to play an important role in determining shipbuilding time and cost, scientific research ... -
Sonar EKF-SLAM and mapping in an structured underwater environment
(Master thesis, 2020)En av de store utfordringene for autonome undervans farkoster idag er navigering i lengre perioder uten og g˚a opp til overflaten for og korrige posisjons estimatione ved hjelp av GNSS. En ny teknikk som kan være i stand ... -
Sonar tracking and obstacle avoidance for navigation of ROV
(Master thesis, 2018)Remotely Operated Underwater Vehicles (ROVs) have represented a revolution by replacing divers. But now robotics can increase the efficiency of underwater operations in a new step of technology. This is mainly due to its ... -
Sonar-Based Monte Carlo Localization for Autonomous Underwater Vehicles
(Master thesis, 2019)Hovedmålet med denne masteroppgaven er å undersøke bruk av akustiske sensorer for å lokalisere et undervannsfartøy. Bruk av bildesonar er ønskelig på grunn av sensorens lave kostnader og vekt. Masteroppgaven begynner med ... -
Soot Investigation on Fish Oil Spray Combustion in a Constant Volume Cell
(Journal article; Peer reviewed, 2015)Maritime environmental regulations stipulate lower emissions from the shipping industry. To cope with these rules, improving the combustion processes, make use of cleaner alternative fuels and implement exhaust gas cleaning ... -
Spar floating wind turbine design optimization with concrete substructures
(Master thesis, 2023)Denne avhandlingen undersøker gjennomførbarheten av å inkorporere betongstrukturer i en optimaliseringsmodell, basert på to forenklede spar-strukturer utviklet av Oh et al. [55] for å støtte en 10 MW DTU vindturbin [2]. ... -
SPAR Type Offshore Wind Turbine Subjected to Ship Impacts
(Master thesis, 2021)Et økende fokus på fornybar energi har ført til en rask utvikling av havvindindustrien de siste årene. For å takle det økende kraftbehovet økes størrelsen av vindturbinene og de flyttes lenger offshore. Det fører til at ... -
Spar-type vertical-axis wind turbines in moderate water depth: A feasibility study
(Journal article; Peer reviewed, 2018)The applications of floating vertical-axis wind turbines (VAWTs) in deep water have been proposed and studied by several researchers recently. However, the feasibility of deploying a floating VAWT at a moderate water depth ... -
Spare Parts Evaluation in the Oil and Gas Industry
(Master thesis, 2015)The main objective of this master thesis is to develop a generic spare parts evaluation process flow based on NORSOK Z-008 and the daily practice in the Norwegian oil and gas industry. Additionally, a case study has been ... -
Spare Parts Management Methodology Development and Cost Evaluation - For offshore production facilities
(Master thesis, 2017)In the aftermath of the drop in oil price in 2014, the global energy industry has been in constant search for new business areas and more cost efficient solutions in order to stay competitive. The industry quickly recognized ... -
Spatial variations in wave conditions at aquaculture sites
(Master thesis, 2020)Målet med denne Masteroppgaven er å undersøke romlig variasjon av bølgeforhold på et havbruksanlegg, og å prøve å finne ut om romlig variasjon kan ha en effekt på påliteligheten til lokalitetsundersøkelser slik de gjøres ... -
Spatio-temporal variation in sea state parameters along virtual ship route paths
(Peer reviewed; Journal article, 2021)The article presents a study investigating the level of variation in sea state parameters encountered by sailing ships crossing the oceans. The sea state parameters have been obtained from a reanalysis, in this case the ... -
Species separation efficiency and effect of artificial lights with a horizonal grid in the Basque bottom trawl fishery
(Peer reviewed; Journal article, 2022)Achieving effective size selectivity for different species within a fishing gear is a major challenge in mixed fisheries. Fish behaviour may be exploited to separate species into separate codends where different selective ... -
Specifying performances for Best Available Technique (BAT) evaluations in offshore developments
(Master thesis, 2010)The Climate and Pollution Agency (Klif) consider target of national environmental policies when determining which abatement costs are cost-effective. They demand transparent cost/benefit evaluations from operators when ... -
Spectral wave modelling for determining wave exposure in Norwegian aquaculture
