Installation of offshore wind farms contributes approximately 15-20% to the life cycle costs of an offshore wind farm. Moreover, because of its high dependency on weather conditions, it is associated with high risk. The high installation costs of offshore wind can be reduced significantly by innovative installation methods. In this report, first an introduction to the offshore wind installation is given and then the installation effort for a reference wind farm is described. Later on, three innovative installation concepts are described. Additionally, using the “ECN Install” tool the installation of the reference wind farm and three innovation concepts are modelled. ECN Install is a planning and logistics tool developed by ECN for installation planning of offshore wind farms. As a result of the ECN Install calculations, the total installation time and all possible delays for the installation of the reference wind farm and three innovative concepts are presented. It is seen that as compared to baseline modelling, the innovations can save up to 1.5-2 days of time per turbine or foundation installation.
