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 ... -
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 ... -
Heuristic solution methods for ship routing and scheduling problems
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:126, Doctoral thesis, 2009)Ship routing and scheduling is among the most important task for many shipping companies. Today, only few shipping companies use optimization-based decision support systems for routing and scheduling of their fleet. They ... -
A Numerical Study of a Damaged Ship in Beam Sea Waves
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:268, Doctoral thesis, 2009)An important objective of survivability criteria for passenger vessels is to ensure that there is sufficient time called Time To Capsizing (TTC) to evacuate passengers and crew members in case of emergency. This requires ... -

(SINTEF Rapport;, Research report, 2009)Prosjektet DECRIS er finansiert av Norges forskningsråd under SAMRISK-programmet. Det er et samarbeidsprosjekt mellom SINTEF, FFI og NTNU. Prosjektet har utviklet og tilpasset metoder for risikovurdering for kritisk ... -
Experimental investigation and numerical methods in analyzing the ocean current displacement phenomena of longlines
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:112, Doctoral thesis, 2009)As Norwegian fisheries deploy demersal longlines at greater water depths in steep continental slope areas, ocean current displacement—the horizontal movements of longlines from the position at which the anchors are dropped ... -
Two-Dimensional Numerical and Experimental Studies of Piston-mode Resonance
(Dr. ingeniøravhandling, 0809-103X; 2009:53, Doctoral thesis, 2009) -
Numerical investigation of turbulence in a skewed three dimensional channel flow
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:179, Doctoral thesis, 2009)The present doctoral thesis concerns fluid flow in three-dimensional turbulent boundary layers. In such flows, both the direction and the magnitude of the mean flow vary with wall distance. A statistically stationary ... -

Simplified Analysis and Design of Ships subjected to Collision and Grounding
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:15, Doctoral thesis, 2009)Ship collisions and grounding represent significant potential incidents which may result in very unfavorable consequences, such as economic loss, environmental damage and fatalities. In this context, continuous effort is ... -
Bond Graph Modelling of Fuel Cells for Marine Power Plants
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:161, Doctoral thesis, 2009)There is a constant search for alternative solutions improving the fuel efficiency and environmental impact of marine power plants. Fuel cells are regarded as a potential future candidate for significantly reducing pollution ... -
Vortex induced vibrations of free span pipelines
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:106, Doctoral thesis, 2009)Pipelines from offshore petroleum fields must frequently pass overareas with uneven seafloor. In such cases the pipeline may havefree spans when crossing depressions. Hence, if dynamic loads canoccur, the free span ... -
Wave induced effects on floaters of aquaculture plants
(Doctoral Theses at NTNU, 1503-8181; 2010:20, Doctoral thesis, 2010)The main objective of this work is to study wave loads on floaters of fish farms. Several incidents of major fish escapes due to structural collapse of fish farms in harsh weather have motivated this study, as a step towards ... -
