Safe access to the nacelle is required for most maintenance activities. Though ladders are always required, larger turbines also have an elevator. To protect all nacelle components from corrosion, the nacelle is well sealed. The nacelle cover provides weatherproof protection to the nacelle components plus support and access to external components. Reliable and the highest quality lighting is required to facilitate safe personnel access and
exit from the nacelle and tower.
The design life of an offshore turbine is approx. 25 years. The trend for
longer design life on all turbines is due to the maturing of the industry –
asset owners now expect to operate wind farms for such periods without the
technology becoming obsolete or unsupported by suppliers. Extreme loads
due to storms, abnormal events and faults during operation can also be
critical. Typically, an offshore turbine will turn for over 90% of the time.
With long system life time and comprehensive experience from marine and
offshore environments Glamox luminaires will achieve the intended lifetime
of the turbines.
The floating or fixed foundations provide support for the wind turbine, transferring the loads from the turbine at the tower interface level to the sea bed where the loads react. The foundation also provides access for personnel from vessels. Unregulated vibrations result in excessive material wear, which in turn can (and does) cause component failure. Within the Glamox scope of vibration testing, three different types of test are performed: Sinusoidal vibration,various shock tests and random testing.
The substation is the most important structure in an offshore wind farm. This is where all the energy produced by the wind turbines is brought together and converted by transformers to a high voltage transmission. This is necessary to ensure that as little energy as possible is lost during transmission over long distances to the next grid node. If a technical fault occurs on the substation platform all wind turbines in the offshore wind farm will fail to function. This means that maintenance and repair services must meet extremely meticulous and high quality standards.
