Investigation of wave-induced nonlinear load effects in open ships considering hull girder vibrations in bending and torsion
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:357, Doctoral thesis, 2012)For ships with open cross sections, such as container vessels, it is of primary importance to accurately estimate torsional moment (TM) and horizontal bending moment (HBM) as well as vertical load effects. In recent decades, ... -
Investigation of Wave-Induced ULS and ALS Characteristic Loads and Responses on a Pile Structure in the Ekofisk Area - Importance of Breaking Waves
(Master thesis, 2016)A set of metocean contour lines corresponding to annual exceedance probabilities of 10^(-2) and 10^(-4) describing the environmental conditions at the Ekofisk area are established based on hindcast data. These are divided ... -
investigation of which sea states yield the dominating contribution to fatigue accumulation in offshore structure
(Master thesis, 2015)In assessment of the fatigue damage, it has been assumed that the moderate sea states (significant wave height ranged between 4-8m) should have major influence on the offshore structures because they have relatively more ... -

Investigation on Different Shapes of Broad-crested Weirs by Means of CFD
(Master thesis, 2019)Weirs are a type of hydraulic structure used for flow measurement, to regulate the water level in hydropower plants, and for the diversion of water to a reservoir. In this study, the flow over various shapes of broad-crested ... -
Investigation on Flooding-Resistant Performance of Integral Abutment and Jointless Bridge
(Peer reviewed; Journal article, 2020)Bridge washouts connected to flood events are deemed one of the main reasons for structural collapse. Compared to traditional continuous jointed bridges, integral abutment and jointless bridges (IAJBs) have better lateral ... -
Investigation on heat recovery strategies from low temperature food processing plants: Energy analysis and system comparison
(Chapter, 2021)Industrial food processing plants often have significant thermal requirements at both low and high temperatures. These plants can produce a variety of products including frozen, chilled and grilled/steamed foodstuff, ... -
Investigation on methods for making detailed digital models of sculptures and other artefacts
(Master thesis, 2011)Sculptures and other artifacts are exposed on damages and it is hard to avoid them. For cultural heritage preservation new replicas of these objects should be done. For this purpose the best solution is to use non-touching ... -
An Investigation on Reduction of Calcium Added Bauxite Residue Pellets by Hydrogen and Iron Recovery through Physical Separation Methods
(Peer reviewed; Journal article, 2023)This study investigates the properties of H2-reduced calcium-added bauxite residue, self-hardened pellets, and the feasibility of iron recovery through electrostatic and magnetic separation methods. The oxide pellets are ... -
An Investigation on the Current Collection Quality of Railway Pantograph-catenary Systems with Contact Wire Wear Degradations
