1- PROJECT REFERENCE LIST
20 Turbines Installed, 8 Offshore
2 - REpower 5M
• Rated Power 5 MW
• Increased power generation
- Foundation, installation, system & O&M
economies of scale
• Modular drive train
- Based on successful REpower MD/MM
onshore turbines, operational since 1998
• Conservative design
• Focus on long term reliability with
redundancies & extended safety factors
- Twin bearing main shaft protects gearbox
- Gearbox designed to REpower guidelines
- Electrical ‘fail-safe’ single blade pitch with
- Tilted cone & pre-bent rotor blades
- Power electronics in the nacelle
• Exceptionally service friendly
Designed Specifically for Offshore

Minimises loads on gearbox, which as a result only transfers torque
Hollow main shaft for additional stiffness
BenefitCARBTM Toroidal-roller bearing
Can cope with:
- tangential deviation
(permanent 0.5°, temporary max. 1°)
- axial displacement
(out of centre position up to 10% of the bearing width)
Best technical solution for a non locating bearing
Same concept for the generator
Easy disassembly due to flange connections
Load-free pivoting of rotor through:
- CARBTM bearing (non locating bearing)
- Spherical roller bearing (locating bearing)
BenefitTwo bearings on the main shaft
Double Bearing Main Shaft
Excellent yield & power
quality. Low losses
Variable speed avoids
surges & peak loads
Voltage and frequency
matched to grid
Double-fed synchronous,
6 pole continuous
Generous, conservative,
robust design
BenefitsGenerator
Direct lubrication of all
bearings and gears with
oil filtration down to 6µm
2-step helical planetary
gear with one spur
Extended safety factors
BenefitsGearbox
Major Components
Options for different
outputs
- 20 or 33 kV
Cast resin and dry
type transformers
- reduced weight &
fire risk
Cooled by dual fan air
/ air heat exchanger
BenefitsTransformer
Water cooled
4 modules in 2 groups
- Redundant system
- Continued operation
in case one module
fails
Limited to 20% of
output so low losses
and high efficiency
BenefitsConverter
Extended safety factors and redundant features with offshore in mind
Pre-bent to avoid tower
contact
Lightning protection
Glass-fibre reinforced
plastic (GRP) / polyester
with epoxy resin
- Mass - 17.8 tonnes
- Deformation to 17m
Hydraulic holding brakes
- Relieves drives while
idle and removes loads
from yaw gears
BenefitsBlades
Controlled by 8 electrical
yaw drives
External 4 point bearing
with multi disc brakes
BenefitsYaw System
Major Components
No hydraulic fluid
leakage
Individually adjustable
electrical pitch drives
for reliability
Failsafe pitch stop
through battery buffer
Service access from

Stiff but compact
design (transport)

external bearing ring
for ease of
maintenance

Extended safety factors and redundant features with offshore in mind
Service Friendly Design
• Spacious nacelle
• Survival room in tower
• Flange mounted drive train
- Easy disassembly / assembly
• Service crane, lifts up to 3.5
tonnes, designed for:
- Maintenance
- Pitch and yaw drives
- Converter
- Blade inspection
• Heli hoist
