  1. 1. An assessment of circular economy measures in the construction value chain for offshore wind turbines

    University essay from Lunds universitet/Byggproduktion

    Author : Therése Svensson; [2023]
    Keywords : Circular economy; Construction value chain; Wind energy; Offshore wind turbine; Offshore wind farm; Design; Manufacturing; Construction; Operation and maintenance; End of life; Technology and Engineering;

    Abstract : The construction sector is responsible for high energy consumption and large emissions of carbon dioxide, which is strongly linked to building materials. Within the European Union, the construction sector generates more than a third of all waste and circular economy is considered as a suitable approach to tackle these challenges. READ MORE

  3. 2. Decarbonisation of service vessels in offshore wind power through power-to-X self-sufficiency

    University essay from Lunds universitet/Miljö- och energisystem

    Author : Clemens Kellander; Ludvig Fredriksson; [2023]
    Keywords : Alternative fuels; compressed hydrogen; battery; production; energy storage; operation and maintenance; O M; offshore; wind power; service vessel; crew transfer vessel; CTV; service operations vessel; SOV; decarbonisation; global warming potential; life cycle; Technology and Engineering;

    Abstract : This report examines the possibilities of decarbonising operation & maintenance vessels for a prospective floating offshore wind power park at the Utsira Nord site in Norway, through self-sufficient energy carrier production utilizing power-to-X-solutions. Possible alternative fuels are identified as compressed hydrogen, batteries, liquid hydrogen, ammonia, methanol, and biofuels, out of which the former two are the subject for thorough investigation in this report.

  4. 3. Short-term O&M Planning for Offshore Wind Energy

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Miguel de Matos e Sá; [2022]
    Keywords : Offshore wind energy; O M scheduling; optimization; wake effect; weather forecasts; risk analysis; Portugal; WindFloat Atlantic; Havsbaserad vindkraft; planering av drift och underhåll; optimering; wake effect; väderprognoser; riskanalys; Portugal; WindFloat Atlantic;

    Abstract : Significant breakthroughs are currently being achieved for Offshore Wind Energy (OWE), as offshore wind turbines are moving further away from the shore, benefitting from as vaster wind resource availability. On the other hand, the current trends of the OWE industry make new challenges arise. READ MORE

  5. 4. Lifetime extension of offshore wind farms

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Robert Eriksson; [2022]
    Keywords : Lifetime extension; offshore wind power; O M; reliability; ReliaSoft;

    Abstract : Renewable energy sources are in strong demand as the need for clean energy is increasing, driven by the need to reach the environmental targets. Offshore wind power is becoming an attractive source as the technology matures and cost decreases. With time all wind farms age and when the time comes one needs to consider end of life alternatives.

    Author : Lorenzo Cantoni; [2021]
    Keywords : Wind Turbine; Offshore; Blade; Rotor; Computational Fluid Dynamics; Airfoil; Aerodynamic; Aeroelasticity; Simulation; Fluid; Structure; Interaction; Loads; Control; Response; Harmonics; Vibration; Damping; Flutter; Trailing Edge; Flaps; Wind Gust; Lift; Drag; Unsteady; Pressure; Velocity; Vindkraftverk; offshore; blad; rotor; beräkningsvätske-dynamik; flygplatta; aerodynamisk; aeroelasticitet; simulering; vätska; struktur; interaktion; belastningar; kontroll; respons; övertoner; vibrationer; dämpning; fladdring; bakkant; klaffar; vindstöt; lyft; Drag; ostadig; tryck; hastighet;

    Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE
