Turbines
The Siemens 4.0 turbine has a generating capacity of four megawatts and a rotor diameter of 130 metres. On top of the turbine tower, the heart of each turbine is formed by the nacelle which transforms the energy captured by the rotor blades into electricity.
The nacelles
The nacelle is the box-like cover that houses all the components, such as the generator, the drive train, the yaw system, controller cabinets and the brake assembly.
In order to lower service costs and reduce working time, the nacelles have been specifically designed to make the moving parts of geared turbines easier to access. On top, there is room for dropping off a crew by helicopter. Service technicians can also access the turbine by CTV (crew transfer vessel) via the boatlanding or via a SOV (service operation vessel) with motion compensated gangway with access to the TP (transition piece).
The word nacelle is derived from the Old French nacele, which means a small boat or dinghy, which was in turn derived from the Latin navicella. The term is commonly used in aviation design to refer to a covered housing that holds engines.

The rotorblades
The rotor blades were manufactured using Siemens’ proven IntegralBlade process, cast as a single piece without the use of adhesive bonding. At the time of the development and installation, the B63 rotor blade, measuring 63 metres in length and weighing 18 tonnes, was the longest and technologically most advanced blade in the 4-megawatt class. The rotor, consisting of 3 blades which are connected by a hub sweeps an area equivalent almost to the size of two football fields.
Together with the other components for the turbines, the blades were shipped from Esbjerg harbour in Denmark and then installed, using huge cranes.
