The availability of the high capacity crawler cranes at the project site during the construction phase of the wind farm may help the turbine assembly rate, which may significantly vary due to the terrain at the project site. Increasing the crane availability at the project site by optimizing the crane utilization rate will reduce the project duration. As a result, the number of turbines that generate electricity early in the construction phase will increase and the payback time will be reduced, although increasing the number of cranes will result in higher investment costs.
