   Sammanfattning : In the rapidly growing wind energy market, regions with cold climates are currently in the spotlight owing to their abundance of wind resources. However, the operation of wind turbines in cold climate conditions is challenged by serious icing problems. LÄS MER

3. 7. Major Component Replacement on Floating Wind Turbines

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Kilian Galle; [2023]
   Nyckelord :;

   Sammanfattning : Among the challenges that floating offshore wind (FOW) energy faces today, operation and maintenanc ecosts, and especially major component replacements (MCR), are an important cost reduction lever. MCRs are defined as any failure on a wind turbine requiring the change of an entire main component of the turbine, such as a gearbox, generator, blade, nacelle, etc. LÄS MER

4. 8. The Paradigm Shift for Substations Technology within Wind Power Applications from Onshore to Floating

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Ahmad Talaat Hifzy; [2023]
   Nyckelord :Floating; offshore; substation; transformer; GIS; equipment; high-voltage; fatigue; Flytande; havsbaserad; station; transformator; GIS; utrustning; högspänning; utmattning;

   Sammanfattning : Floating wind turbines are attracting more attention as more than three-quarters of the total offshore technical potential is located in deep water, leading to a growing trend in floating wind farm projects. Consequently, it becomes necessary to develop Floating Offshore Substation (FOSS) to step up voltage and efficiently transmit power to the shore with minimal losses. LÄS MER

5. 9. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

   Master-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Författare :Johannes Hall; Albin Larsson; [2023]
   Nyckelord :VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

   Sammanfattning : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. LÄS MER

7. 10. Developing a Cost Model For Combined Offshore Farms : The Advantages of Co-Located Wind and Wave Energy

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Eva Blech; [2023]
   Nyckelord :Wave Energy; Floating Offshore Wind; Co-located Wind-Wave Farm; Levelized Cost of Energy; Multi-Source Offshore Farm; Vågenergi; flytande havsbaserad vindkraft; samlokaliserad vind- och vågpark; nivellerad energikostnad; havsbaserad park med flera källor;

   Sammanfattning : Previous research has displayed that multi-source farms provide an opportunity to reduce the cost of energy and improve the energy output quality. This thesis assesses the cost competitiveness of co-located wind-wave farms, specifically floating offshore wind (FLOW) turbines and CorPower’s wave energy converters (WEC). LÄS MER
