Floating offshore wind is an expanding sector within renewable power generation, offering an opportunity to deliver green energy, in new areas offshore. The floating nature of the substructures permits wind turbine placement in deep water locations. This presentation investigates the installation challenges for the various substructure floating offshore wind types and suggests priority areas for future development to help reduce costs. Specifically tailored design for installation includes expanding the weather window in which these substructures can be transported to and from site and making mooring and electrical connection operations simpler. The simplification of installation methodology will reduce time spent offshore and minimise risks to personnel. The presentation will include the best practice for ease of towing for offshore installation and possible return to port for maintenance will be considered. The installation process for a floating wind turbine varies with substructure type and this will be developed in more detail in the presentation. Floating offshore wind structures require an international collaboration of shipyards, ports and installation vessels, though industry forums. The installation phases, in particular maximum draft of the substructure, are also affected by the construction materials i.e. steel or concrete. In order to facilitate the installation and to minimize costs, the main aspects have to be considered i.e., the required vessel types, the distance from fit out port to site and the weather restrictions. This presentation will be useful for researchers and stakeholders in the offshore wind and offshore engineering sector offering or considering technology solutions for floating wind installations.
