Abstract: A method for repairing a wind turbine is described. The method may include preparing the surface of the blade, removing a plurality of mounting bolts, and replacing the mounting bolts with rod members. The rod members may be bonded to the blade root thereby strengthening the blade root and/or repairing any damaged or weakened regions. This repair may be performed on blades and blade coupling regions of various characteristics as well in modular fashion using pre-molded sections attached together around the blade root. The method of repair may be performed while the blade is still attached to the turbine hub. Wind turbines repaired according to these methods are also described. The method may also be used for attaching and otherwise handling new turbine blades and new wind turbines.

Abstract: A fluid catchment system for a wind turbine is provided. The wind turbine has a nacelle mounted to a tower. The fluid catchment system includes at least one fluid accumulator in fluid communication with the interior of the nacelle and configured to receive fluid exiting from the nacelle. The fluid accumulator is configured to be positioned at least partially beneath the nacelle and to be attached to at least one of the tower and the nacelle. An oil absorbent material may be retained by the fluid accumulator. A fluid collector may be provided to collect fluid from the fluid accumulator. A fluid catchment system having a fluid accumulator located on a wind turbine blade is also provided. Further, a wind turbine including a fluid catchment system is provided.
