Numerical Methods for Flows with Evolving Interfaces
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:12, Doctoral thesis, 2004)
The present thesis addressed two important aspects of Computational Hydrodynamics: solution methods for following evolving interfaces, and stabilisation techniques for finite element method sin the context of convection-dominated, ...
Three-Dimensional Analysis of Slamming
(Dr. ingeniøravhandling, 0809-103X; 2003:85, Doctoral thesis, 2003)
Impact between the water and ship, i.e. slamming can cause important global and local effects. A numerical method has been applied to predict water entry loads on three-dimensional bodies. When the local angle between the ...
Efficient Prediction of Dynamic Response for Flexible and Multi- Body Marine Structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:262, Doctoral thesis, 2008)

A Numerical Study of Wave-in-Deck Impact using a Two-dimensional Constrained Interpolation Profile Method
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:153, Doctoral thesis, 2009)
A Constrained Interpolation Profile method following Hu and Kashiwagi (2004) is developed for wave impact applications. Two-dimensional, unsteady, viscous and incompressible flow is assumed. The numerical model is a finite ...
Numerical Simulation of Three-dimensional Viscous Flow around Marine Structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:170, Doctoral thesis, 2005)
The first part of the thesis covers the theoretical background for computational fluid dynamics; specifically, the incompressible Navier-Stokes equations. Some general solution methods are reviewed, as well as the most ...
Maneuvering and Seakeeping of a Single Ship and of Two Ships in Interaction
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:55, Doctoral thesis, 2008)
The main objective of this thesis has been to study the maneuvering and seakeeping of two interacting ships. A systematic approach is adopted. First, the maneuvering behaviour of a single ship in regular waves was considered. ...
Ultimate Strength and Reliability based Design of Ship Hulls with Emphasis on Combined Global and Local Loads
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:27, Doctoral thesis, 2009)
During the last few decades, the emphasis in structural design of ships has moved from the allowable stress design to the ultimate limit state design. The ultimate limit state represents the collapse of the structure due ...
Bond Graph Modeling of Marine Power Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:56, Doctoral thesis, 2009)
Mathematical models for an All Electric Ship component library is developed in this thesis. The main motivation for writing this thesis is to develop a model library that gives the opportunity to simulate both existing ...
Modelling of flexible slender systems for real-time simulation and control applications
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:222, Doctoral thesis, 2007)
The main contributions in the present thesis are the development of two mathematical models describing the motion and forces in slender mechanical systems like cables. The main advantage by the models proposed is the ...
