1. 1. CFD Analysis of Water Replenishment Holes in an Offshore Wind Turbine Foundation

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Shubham Arvind Tupkar; Swetha Sappe Narasimhamurthy; [2022]
   Nyckelord :CFD; Wave Dynamics; Implicit LES; GABC; OpenFOAM; Stokes V; Monopile Foundation; Replenishment Holes;

   Sammanfattning : The study presented in this thesis investigates the passive exchange of enclosed water with seawater in an offshore wind turbine foundation. This thesis was undertaken in collaboration with Vattenfall R&D, Älvkarleby, Sweden. The water exchange is studied by utilizing Computational Fluid Dynamics (CFD) simulations. LÄS MER

3. 2. CABLES DECOMMISSIONING IN OFFSHORE WIND FARMS: ENVIRONMENTAL AND ECONOMICAL PERSPECTIVE

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Omer Al-Sallami; [2021]
   Nyckelord :Offshore wind energy; subsea cables; decommissioning;

   Sammanfattning : Addressing the decommissioning issues is vital to ensure a sustainable and effective process of such an essential part of the project life cycle. While there is a set of good practices and regulations that govern most of the decommissioning activities, the cable decommissioning issue is still in a big debate and often left abandoned at the seabed due to environmental concerns, as justified by most developers.

4. 3. Critical perspectives: North Sea offshore wind farms. : Oral histories, aesthetics and selected legal frameworks relating to the North Sea.

   Master-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

   Författare :Joanne Moss; [2021]
   Nyckelord :Aesthetics; Coastal; Decay; Decommission; Development permission; European Landscape Convention; Fluid dynamics; Horizon; Industrial; Judicial review; Marine management; Maunsell; Monopile; NASA; North Sea; Offshore; Oral history; OSPAR; Scotland; Scour; Sealand; Sea plumes; Seascape; Sediment; SPM; Suspended particulate matter; Transience; Trawler; Turbine; United Kingdom; Wind farm.;

   Sammanfattning : The study is developed from five in-depth interviews with individuals from different walks of life who have interacted significantly with the North Sea. The study discusses change in the North Sea specifically in the development of fixed turbine wind farms and their physical and aesthetic effects. LÄS MER

5. 4. ASSESSMENT OF THE OFFSHORE WIND POTENTIAL IN THE CARIBBEAN SEA TO SATISFY THE DEMAND OF ELECTRICITY IN LATIN AMERICA AND THE CARIBBEAN REGION

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :JOSE ORLANDO GOMEZ SARA; [2019]
   Nyckelord :Offshore Wind Power; Electricity Demand; Infinite Wind Farm; Latin America and the Caribbean;

   Sammanfattning : The offshore wind potential of the Caribbean Sea has barely been exploited. Currently, the offshore wind power industry in Latin America and the Caribbean region is still at very early stages, leaving aside an important resource that otherwise could contribute to satisfy the growing energy demand of the zone.

7. 5. MEASUREMENT DRIVEN FATIGUE ASSESSMENT OF OFFSHORE WIND TURBINE FOUNDATIONS

   Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Frauke Wilberts; [2017]
   Nyckelord :offshore wind turbine; monopile foundation; wind power; fatigue assessment;

   Sammanfattning : The installed capacity of offshore wind turbines in Europe is increasing with the monopile being the most common type of foundation. During its lifetime an offshore wind turbine is exposed to high dynamic loads which eventually can result in the fatigue of the substructure. LÄS MER
