For a FOWT (Floating Offshore Wind Turbine) It’s so hard to install a blade offshore because of the motion of the FOWT and the crane vessel.
An installation Guide is needed.
CONVENTIONAL
It's hard to insert bolts on Blade into the bolt holes of the Bearing because the clearance between a bolt and a bolt hole is so small ( ex. few mm).
OUR PROPOSAL:
The diameter at the entrance side of the bolt hole is much larger than the bolt diameter and tapers toward the exit side.
