1453. Comparison of the ride performance of an integrated suspension model
(Journal article; Peer reviewed, 2014)Vehicle suspension is one of the important components to reduce vibration from the road. The vehicle seat suspension acts as another component to provide ride comfort, especially to reduce driver fatigues for long hour’s ... -
2D experimental and numerical study of moonpool with recess
(Master thesis, 2018)The background for this master's thesis is the complications that is faced in the industry with regards to operational time inside moonpools. This thesis focuses on moonpools with recess, and the fluid resonant phenomena ... -
2D Numerical Investigation of the Non-Linear Forces Acting on the Sevan SWACH OWT
(Master thesis, 2023)Flytende havvind har i senere år blitt identifisert som en viktig løsning på energi for å nå null-utslipps klima målet. Ved å ta i bruk de sterke og konsistente vindkastene ute på havet kan dette annses som en mulig ... -
2D Numerical Study on Wake Scenarios for a Flapping Foil
(Chapter, 2021)Fishes are talented swimmers. Depending on the propulsion mechanisms many fishes can use flapping tails and/or fins to generate thrust, which seems to be connected to the formation of a reverse von Kármán wake. In the ... -
A 2D+t approach for the transverse viscous loads in a modular maneuvering model
(Peer reviewed; Journal article, 2021)The importance of the transverse viscous loads, in a modular maneuvering model, is investigated. A method to estimate steady sectional drag coefficients is first presented. A 2D+t approach, which accounts for forward-speed ... -

3D Domain Decomposition for Violent Wave-Ship Interactions
(Journal article, 2013)A 3D Domain-Decomposition (DD) strategy has been developed to deal with violent wave-ship interactions involving water-on-deck and slamming occurrence. It couples a linear potential flow seakeeping solver with a Navier–Stokes ... -
A 3D fully-nonlinear potential-flow solver for efficient simulations of large-scale free-surface waves
(Journal article; Peer reviewed, 2022) -
3D motion dynamics of axisymmetric bodies falling through water
(Journal article; Peer reviewed, 2018)A new simplified method for analysis of 3D motion dynamics of axisymmetric slender bodies falling from air through water is presented. Slender-body theory for potential flow of incompressible water is combined with 2D + t ... -
3D visualization of autonomous underwater robots
(Master thesis, 2014)This thesis has an objective aimed to develop a functional real-time visualization of an underwater robot manipulator, and present the relevant theory and steps related to this system. Then the system should be prepared ... -
A 2D Experimental and Numerical Study of Moonpools With Recess
(Chapter, 2018)Moonpool resonance is investigated in a two-dimensional setting in terms of regular, forced heave motions of a model with moonpool with different rectangular-shaped recess configurations. A recess is a reduced draft zone ... -
A 5MW direct-drive generator for floating spar-buoy wind turbine: Drive-train dynamics
(Journal article; Peer reviewed, 2017)This article proceeds with investigations on a 5 MW direct-drive floating wind turbine system (FWTDD) that was developed in a previous study. A fully integrated land-based direct-drive wind turbine system (WTDD) was created ... -
A Bayesian approach to risk modeling of autonomous subsea intervention operations
(Journal article; Peer reviewed, 2018)The introduction of autonomy in subsea operations may affect operational risk related to Inspection, Maintenance, and Repair (IMR). This article proposes a Bayesian Belief Network (BBN) to model the risk affecting autonomous ... -
A Bayesian network approach for analysing the failure of jackup rigs operations in West Africa.
(Master thesis, 2022)Den globale energietterspørselen vil øke de neste ti ̊arene p ̊a grunn av befolkningsvekst og økt forbruk. Samtidig som europeiske land øker investeringene sine i fornybar energi, som havvind, har de vist seg ̊a være ... -
A BBN Risk Analysis of Cruise Ship Groundings in Northern Norway during Winter
(Master thesis, 2020)Nord-Norge har oppnådd mer fokus som en destinasjon for cruiseskipturisme de seneste årene. Antall cruiseanløp har økt både for sommer- og vintersesongen. En grunnstøting for et cruiseskip i disse farvannene kan føre til ... -
A Benchmark Radar-Based Dataset from the Canal in Trondheim
(Master thesis, 2024)Den maritime industrien har sett økende interesse for autonome fartøy, noe som vil kreve robust situasjonsforståelse for å navigere trygt. Denne oppgaven tar for seg gapet i tilgjengelig maritime radar-baserte datasett ved ... -
A Bond Graph Approach for Modelling Systems of Rigid Bodies in Spatial Motion
(Master thesis, 2014)The research presented in this thesis seeks to improve the current state and technique for dynamic modelling of systems of rigid bodies in spatial motion. The research have been focused around modelling of underwater ... -
A Boundary Element Method Applied to Strongly Nonlinear Wave-Body Interaction Problems
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:141, Doctoral thesis, 2007)A two-dimensional Boundary Element Method (BEM) based on potential flow theory is developed to study wave-body interaction problems with strongly nonlinear effects. In particular, the following problems are studied. One ... -
A brute-force spectral approach for wave estimation using measured vessel motions
(Journal article; Peer reviewed, 2018)The article introduces a spectral procedure for sea state estimation based on measurements of motion responses of a ship in a short-crested seaway. The procedure relies fundamentally on the wave buoy analogy, but the wave ... -
