1. 16. Direct Calculation of Wave-Induced Loads and Fatigue Damage of Container Vessels

   Författare :Zhiyuan Li; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fatigue; stress concentration factor; direct calculation; Container ship; fatigue routing; wave-induced torsion.; extreme loading; nonlinear wave loads;

   Sammanfattning : Container ships and their rules for fatigue design are in several ways differentcompared with other types of commercial ships such as tankers and bulk carriers. Forexample, most modern container ships have a pronounced bow flare and an overhangstern. LÄS MER

3. 17. Ice and wind loads on guyed masts

   Författare :Claes Fahleson; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : Atmospheric icing is a large problem for many structures located in regions with cold climate. Structures as guyed masts and overhead transmission lines and towers are particularly exposed. A 323 meter high guyed TV and radio mast in Arvidsjaur in Northern Sweden was equipped with an extensive data collection system in the winter 1988-89. LÄS MER

4. 18. Offshore renewable energy systems : Quantification of extreme loads using computational methods

   Författare :Eirini Katsidoniotaki; Malin Göteman; Alison Raby; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; offshore systems; wave energy; CFD; extreme events; machine learning; Bayesian experimental design; active learning; surrogate modeling;

   Sammanfattning : This Ph.D. thesis investigates the dynamic response of offshore energy systems in extreme waves. The use of offshore energy technologies, such as wave energy systems and offshore wind turbines, is crucial for transitioning to clean energy and mitigating the effects of climate change. LÄS MER

5. 19. Wave Loads on Offshore Wind Power Plants

   Författare :Jenny Trumars; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ocean engineering; shallow water; fatigue; Non-linear waves; wave load; wind energy converter; perturbation theory;

   Sammanfattning : The thesis gives a short introduction to waves and discusses the problem with non-linear waves in shallow water and how they effect an offshore wind energy converter. The focus is on the realisation of non-linear waves in the time domain from short-term statistics in the form of a variance density spectrum of the wave elevation. LÄS MER
