Cost-effectivity of logistical strategies for the installation of offshore wind turbine substructures

The ever-increasing size of offshore wind turbine substructures and the development of wind farms at sites further offshore, with greater water depths and with extremer weather conditions, raise logistical challenges that have never been faced before. Additionally, the offshore wind industry has to deal with governments cutting subsidies, small...

The choice of feeder container ships for the North Sea and Baltic Sea region

Container ships are becoming larger and larger, but also more numerous. As a result, these large ships are pushing their smaller counterparts down the line, until these smaller ships are no longer efficient for trade routes. The focus area of this thesis is on the North Sea and Baltic Sea area, in particular the area between the West coast of...

An investigation of installation strategies to install next-generation offshore wind turbine generator components: Feedering vs. Shuttling, an efficient installation process for the future

Climate change is triggering among others a larger demand for offshore wind energy. This leads to new developments of which larger next-generation Wind Turbine Generators is the most relevant. These next-generation WTGs create problems for the carrying capacity of current-day installation jack-up vessels that work according to the conventional...
