The monopile is installed in a piling frame attached to the jack-up platform and driven down to the required depth by means of a hydrohammer.
2.
Installation of the transition piece
A transition piece between the foundation and the turbine tower allows for adjustment of the verticality of the monopile and compensates for eventual damage to the topmost part of the pile which has occured during driving.
Attachment of the intermediate section to the foundation is done by means of the grouting technique.
3.
Installation of the tower and nacelle
The tower is made up of two or three segments. The nacelle is assembled onshore. Its main components are the generator, gearbox, yaw and brake systems.
4.
Rotor Transportation
The rotor, which consists of the hub and the blades, is assembled onshore and transported to the offshore location on a second jack-up platform.
5.
Rotor Installation
The crane, which is placed on the first platform, lifts up the rotor and a second, smaller crane on the transport platform guides the lifting movement by holding one of the blades
