  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. 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

  5. 4. Non-linear Wave Impact on Monopile Structures

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Philipp Schöpfer; [2016]
    Nyckelord :;

    Sammanfattning : This Master Thesis deals with non-linear wave impacts on monopile structures by introducing a potential flow solver named OceanWave3D (OCW3D) for simulating free surface waves and their kinematics under engineering consideration. A comparison to Rambøll’s analytical tool WAVGEN is conducted with the aim of providing distinct recommendations on the application and suitability of both programs for the monopile design. LÄS MER
