Sloshing-induced motions of a spar inside a cylindrical dock with baffles in waves
(Peer reviewed; Journal article, 2023)The motions of a free floating offshore wind turbine’s (OWT) spar-type platform inside a bottom-less moored cylindrical dock are investigated for incident wave frequencies near the first lateral sloshing resonance, focusing ... -
Slug flow and waves induced motions in flexible riser
(Journal article; Peer reviewed, 2018)Flexible risers provide optimum solutions for deep water offshore fields. Reliable dynamic analysis of this kind of slender structure is crucial to ensure safety against long time fatigue failure. Beyond the effects from ... -
Small scale experimental validation of a numerical model of the HarshLab2.0 floating platform coupled with a non-linear lumped mass catenary mooring system
(Peer reviewed; Journal article, 2020)When focusing on mooring system numerical modelling, the efforts are focused on validating models that increase the accuracy and maintain the computation time under reasonable limits. In this paper an approach for modelling ... -
Small Water Plane Area Solutions for Access of Offshore Wind Turbines
(Master thesis, 2015)In 2014, 536 offshore wind turbines were installed on European shelf, connecting an average of 5.9 MW to the grid every day. About two thirds of this were installed in the North Sea. This new and emerging market represents ... -
Small-Scale Automation in Shipbuilding - An Investment Study for Automated Hull Production in High-cost Countries
(Master thesis, 2015)The globalized market enforces a great cost pressure on all the shipbuilding actors. Norwegian yards, representing countries with high local wages and prices, is under pressure to make changes if they want to keep up with ... -
Snaking Behavior of Umbilicals
(Master thesis, 2014)Umbilical is a hardware element that connects the subsea systems to the top side systems of a floating production unit. During its manufacture, storage and installation, sometimes it shows behaviour like snake as found in ... -
Soft Causes with Hard Consequences: The role of organisational factors in the creation of structural integrity
(Journal article; Peer reviewed, 2015)Structural integrity is usually seen as a result of design, calculations, the correct choice of materials and good engineering practice in general. In this paper, we will shed light on organisational aspects that can ... -
Software Development and Integration of a Hyperspectral Imaging Payload for HYPSO-1
(Peer reviewed; Journal article, 2022)This paper presents the software architecture, development, and integration of a Commercial Off-The-Shelf (COTS) based hyperspectral imaging payload onboard the HYPerspectral Smallsat for Ocean observation (HYPSO-1) CubeSat. ... -
Software-in-the-loop testing of a wave filter - with application to cyber-physical testing of a floating wind turbine
(Master thesis, 2023)Denne masteroppgaven utforsker anvendelsen og ytelsen til en tilstandsestimator i en “programvare-i-sløyfe” (SIL) konfigurasjon. “Programvare-i-sløyfe” er en metode som brukes i utvikling av modeller der kontrollsystemer ... -
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
