    • Monopile foundations - Effect of scour protection on eigenfrequency of offshore wind turbines 

      Sævdal, Kjell Inge (Master thesis, 2017)
      Monopile foundations is the most popular foundation type for offshore wind turbines, with over 80 % of the substructures being monopile foundations. When placed in a marine environment monopiles is prone to scour around ...
    • Mooring system design for floating wind turbines 

      Laks, Annika (Master thesis, 2014)
      Recently, there has been a lot of research on floating wind turbines. These structures have to be moored for a station keeping, which is relatively straightforward for deep waters. In transitional water depths (35-70 m) ...
    • Mortar Water Content Impact on Masonry Strength 

      Slapø, Fredrik; Kvande, Tore; Høiseth, Karl Vincent; Hisdal, Jorun-Marie; Lohne, Jardar (Journal article, 2018)
      Building without sufficient knowledge can entail risk concerning structural safety and resource efficiency. The authors of this paper share the view that mortar water content are subject to large variations, and that the ...
