aeroMaster for offshore applications

The systematic further development of the proven aeroMaster technology for offshore use, even more reliable, more efficient.

Component cooling system
High-capacity water cooling system enables full-power operation up to 40°C
Helicopter hoist platform
Platform designed according to common standards for safe personal and material hoisting. Optionally, a helicopter landing platform can be implemented.
Transformer
A dry-type air/water cooled transformer with high safety and high efficiency
Converter system
Medium voltage IGCT or low voltage IGBT full converter depending on generator technology following the offshore turbine trend for greater reliability
Internal service crane
Single-girder bridge crane with electrical chain hoist and slewing jib hub crane for maximum crane access area offers in combination with our spacious nacelle cover and even platform design excellent conditions for offshore maintenance and repair jobs
Generator system
Highest flexibility with alternative generator systems (squirrel cage or permanent magnet) and different
voltage levels optimized for offshore applications with lowest possible maintenance effort
Nacelle cooling
Two redundant crossflow heat exchangers keep the nacelle temperature at an acceptable level and together with the nacelle sealing and dehumidification system ensure that components are protected from outside air impact
Hydraulic torque support
Elastomer bearing with hydraulic features reduces constraint forces on gearbox and main bearings
Yaw system
Proven technology with slewing ring, hydraulic calliper brakes and electrically driven planetary gearbox drives
Rotor bearing unit
Zero-play double rotor bearing system for increased gearbox and bearing reliability
Pitch system
State-of-the-art electric pitch system with modern drive and emergency power supply technology

The design of the aeroMaster 5.0 wind turbine typifies the know-how our engineers have accumulated from two successful development projects for 5 MW offshore wind turbines. This makes aerodyn the leading global player in the design and implementation of large offshore wind turbines.

Like with the onshore aeroMaster models, emphasis in this aeroMaster 5.0 was placed on reliability, cost effectiveness and high yields. The proven and reliable aeroMaster drive train technology has also been adapted for the aeroMaster 5.0 offshore turbine. The aeroMaster 5.0 is available in different versions comprising two alternative electrical systems (squirrel cage or permanent magnet generator) with different voltage levels (low voltage or medium voltage) and two different rotor diameters ranging from 130 m to 139 m for an optimum energy yield in sites with different wind conditions.

Optimization for sites with high and mean wind speeds flowed into the design as well and makes operation cost-effective in all wind conditions. As a result, this opens up a far greater number of potential installation sites, making the aeroMaster 5.0 optimally equipped also for future offshore markets.
