Gap Resonance Analyzed by a Domain-Decomposition Method
(Chapter, 2011) -
Gas cavity-body interactions: Efficient numerical solution
(Journal article; Peer reviewed, 2015)The paper investigates the interactions occurring between a gas cavity, the surrounding liquid and the nearby structures. In more detail, focus is in the characterization of the various dynamical phases (e.g. “acoustic ... -
Gaseous Fuel Injection Characterization Using an Experimental Rig
(Master thesis, 2024)Denne oppgaven presenterer en eksperimentell karakterisering av gassinnsprøyting ved bruk av en Bosch GDI-innsprøyter. Forskningen er basert på en eksperimentell magerbrennende gnisttenningsmotor med et forkammerkonsept ... -
Gear Contact Fatigue Reliability Analysis for Wind Turbines Under Stochastic Dynamic Conditions Considering Inspection and Repair
(Chapter; Peer reviewed, 2014)Reliability is one of the most important features of the wind turbine gearbox, especially in offshore wind turbines (OWTs). This paper describes a general way to perform gear contact fatigue reliability analysis for wind ... -
Generating Realistic Underwater Images Using Contrastive Learning
(Master thesis, 2023)Artificial intelligence (AI) has gained tremendous traction in the past decade, both due to improvements in computational power and the availability of a cornucopia of useful datasets. AI techniques have seen increased ... -
A generic approach to analysing failures in human – System interaction in autonomy
(Peer reviewed; Journal article, 2020)Autonomous systems operation will in the foreseeable future rely on the interaction between software, hardware and humans. Efficient interaction and communication between these agents are crucial for safe operation. ... -
Genset scheduling in a redundant electric power system for an offshore vessel using mixed integer linear programming
(Journal article, 2021)This paper proposes several schemes for optimal scheduling of power producers in a shipboard power system for a typical offshore supply vessel, having a multiple number of possibly varying capacity gensets. The proposed ... -
Glacial Ice and Offshore Structure Impacts under Wave and Current Excitation
(Journal article; Peer reviewed, 2019)Bergy bits and growlers (i.e., glacial ice features with a waterline diameter < 15 m) travelling with waves can pose great threats to offshore structure and ships operating in the high North. It is generally more difficult ... -
Glacial ice impacts: Part I: Wave-driven motion and small glacial ice feature impacts
(Peer reviewed; Journal article, 2021)Glacial ice features in the northern and central Barents Sea may threaten ships and offshore structures. Particularly, small glacial ice features, which are difficult to detect and manage by concurrent technologies, are ... -
Glacial ice impacts: Part II: Damage assessment and ice-structure interactions in accidental limit states (ALS)
(Peer reviewed; Journal article, 2021)Floating glacial ice features of various sizes pose a substantial threat to the structural integrity of offshore structures in ice-prone regions. Relatively small ice feathers, e.g., bergy bits and growlers, are a major ... -
Global Analysis of a Floating Bridge
(Master thesis, 2013)There is an ongoing political debate in Norway concerning how to improve the communication between communities on the western coastline. A proposed solution is to build floating bridges over some of the crossings that today ... -
Global Analysis of a Shipping Lane for a Floating Bridge
(Master thesis, 2015)The main objective of this thesis is to conduct a global analysis of a proposed shipping lane for a floating bridge that in future will operate in Halsafjorden. The model is simplified as only the shipping lane will be ... -
Global Asymptotic Position and Heading Tracking for Multirotors Using Tuning Function-Based Adaptive Hybrid Feedback
(Journal article; Peer reviewed, 2022) -
Global Asymptotic Tracking for Marine Surface Vehicles using Hybrid Feedback in the Presence of Parametric Uncertainties
(Chapter, 2021)In this paper, we propose a hybrid adaptive feedback control law for global asymptotic tracking control for marine surface vehicles in the presence of parametric uncertainties. The hybrid feedback is derived from a family ... -
Global buckling of pipelines - A study on different soil models
(Master thesis, 2016)Pipelines are essential units as a energy transportation method nowadays. Buckling behaviors have been recognized as majority because it can cause sudden disconnection of pipelines and this may lead the pipeline to ... -
Global force and moment in rectangular tanks through a modal method for wave sloshing
(Journal article, 2017)Basing on a modal description of the sloshing phenomenon, formulas for the global force and moment acting on two-dimensional rectangular tanks are proposed. These are extensively validated through comparison with experimental ... -
Global sensitivity analysis and repeated identification of a modular maneuvering model of a passenger ferry
(Journal article; Peer reviewed, 2018)In the paper a modular manoeuvring model of the passenger ferry “Landegode” is built, validated and studied. Global sensitivity analysis based on the variance decomposition is performed to assess the sensitivity of the ... -
Global Shipping Emissions from a Well-to-Wake Perspective: The MariTEAM Model
(Peer reviewed; Journal article, 2021)Improving the robustness of maritime emission inventories is important to ensure we fully understand the point of embarkment for transformation pathways of the sector toward the 1.5 and 2°C targets. A bottom-up assessment ... -
Global slamming forces on jacket structures for offshore wind applications
(Journal article; Peer reviewed, 2018)This study investigates the global slamming forces due to plunging breaking waves on a jacket structure, based on the statistical analysis of the experimental data from the WaveSlam project. Hammer tests and wave tests ... -
