  2. 11. Offshore deployments of marine energy converters

    Author : Maria Angeliki Chatzigiannakou; Irina Temiz; Mats Leijon; Tony Lewis; Uppsala universitet; []
    Keywords : offshore deployments; risk assessment; wave energy converter installation; marine current energy converter installation; economic efficiency; time efficiency; offshore operations; point absorber; hydrodynamic analysis; slack sling criterion; hoisting system failure.;

    Abstract : The depletion warning of non-renewable resources, such as gas, coal and oil, and the imminent effects of climate change turned the attention to clean and fossil fuel-free generated electricity. University research groups worldwide are studying solar, wind, geothermal, biomass and ocean energy harvesting. READ MORE

  4. 12. Wave Loads on Offshore Wind Power Plants

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

    Abstract : 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. READ MORE

  5. 13. Offshore renewable energy systems : Quantification of extreme loads using computational methods

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

    Abstract : 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. READ MORE
