From Teaching as Transmission to Constructive Alignment: A Case Study of Learning Design
(Peer reviewed; Journal article, 2021)This paper reports on an action research study on curriculum design in an optional module at the Norwegian University of Science and Technology. There were two professors teaching their respective parts, henceforth termed ... -
FSI Analysis of Abnormal Wave Slamming Events
(Master thesis, 2020)Slamming impact is a hazardous phenomenon to ships and offshore structures, which is characterised by a highly nonlinear coupling interaction between the structure and the fluid. To evaluate it correctly and accurately is ... -
Fuel Cells in Offshore Oil and Gas Production
(Master thesis, 2017)The petroleum industry is confronted with a two-faced challenge as global energy demand is set to increase simultaneously as greenhouse gas emissions must be reduced in order to combat global climate change. With the signing ... -
Fuel consumption and emission reduction of marine lean-burn gas engine employing a hybrid propulsion concept
(Peer reviewed; Journal article, 2021)As the emission legislation becomes further constraining, all manufacturers started to fulfill the future regulations about the prime movers in the market. Lean-burn gas engines operating under marine applications are also ... -
Fuel savings for a general cargo ship employing retractable bow foils
(Journal article, 2018)Route simulations were performed on a 100 m long (between perpendiculars) general cargo ship equipped with retractable bow-mounted foils, so-called wavefoils, for resistance reduction and motion damping in waves. Two ... -
Full long-term extreme response analysis of marine structures using inverse FORM
(Journal article; Peer reviewed, 2017)An exact and an approximate formulation for the long-term extreme response of marine structures are discussed and compared. It is well known that the approximate formulation can be evaluated in a simplified way by using ... -
Full-Scale Sea Trials of a Motion Control System for ROVs Based on a High-Gain State Observer
(Journal article, 2014)This paper reports selected results from full-scale sea trials, along with the description of the digital version implemented in practice, of a Motion Control System (MCS) previously proposed by the authors in the ... -
Fully-nonlinear wave-current-body interaction analysis by a harmonic polynomial cell method
(Journal article; Peer reviewed, 2014)A new numerical 2D cell method has been proposed by the authors, based on representing the velocity potential in each cell by harmonic polynomials. The method was named the harmonic polynomial cell (HPC) method. The method ... -
Future-Proofing Cruise Ships by Designing for Flexibility
(Master thesis, 2020)I denne masteroppgaven undersøker vi verdien av å fremtids forsikre cruise skip ved å designe for fleksibilitet. Utforske verden med cruise skip har vært populært i flere tiår, og i de senere årene har cruise industrien ... -
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 ... -
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 ... -
