Less is more.
OUR TURBINE COMBINES A NUMBER OF UNIQUE TECHNOLOGIES THAT MAKE A SUPERIOR OFFSHORE TURBINE
Fully sealed
The tower and nacelle of the turbine are fully sealed to keep out the salty and moist
sea air. This protects our valuable components, increases operational availability and
saves a great deal of maintenance.
Single main bearing & generator in one
The XEMC-Darwind turbine is based on the single main bearing concept. The bearing
has a large diameter that enables it to bear the enormous force of the rotor: there is
no central shaft. The bearing component is integrated into the generator and is
possible because the turbine uses direct-drive technology. This innovative design not
only creates a compact and lightweight permanent magnet direct-drive generator; it
also results in significant savings in logistics, foundation and support structure costs.
External air generator cooling
The exterior shell of the generator is covered with small surface extensions to transfer
the heat to the cool air. This avoids using a powerful, potentially unreliable cooling
system.
Light weight
Innovative design and new materials have resulted in a easy to instal, large, lightweight
turbine with a capacity of 5 MW.
Direct drive principle
Our turbines are based on the direct drive principle, thereby dispensing of the need for
gearboxes. Gearboxes pose a significant problem for offshore wind turbines because
the torque of multi-megawatt wind turbines is enormous.
In contrast, gearless turbines require less maintenance, are more reliable and therefore
boast higher operating availability.
Permanent magnets in the generator
As no additional electricity is required to magnetise the rotor coils, there is no need for
generator `brushes` to transfer this electricity. This increases both efficiency and
reliability because the rotating part of the generator contains no electrical systems.
Monitoring system
The highly sophisticated monitoring system for wind farms enables maximum
control and an efficient O&M system at a minimum of cost.
Offshore logistics
Logistics are the dominant cost drivers of the offshore world, which is why we partner
with experienced marine contractors to offer our customers an optimised package.
