Noise
Consider during blade shape design
Essential that design assessment takes this into consideration.
Electricity
Contact with overhead cables during lifting operations
Careful planning of each stage.
Electricity
• In offshore wind farms buried cables can get damaged from trawlers and anchors and the exposure of cables to hydrodynamic loading;
• Working with high voltage and low voltage currents;
• Contact with overhead cables during lifting operations and crane movements on site.
• Farming activities on site e.g. ploughing adjacent to underground cables
avoid live working. Trained personnel. Regular inspection and maintenance, PTW, Electrical Safety Rules.
Electricity
Contact with overhead cables during lifting operations. Fault-finding and crane movements on site
Electricity
Overhead cables, buried cables (i.e. contact during lifting operations, during excavation)
site survey, CAT scans, warnings and “goal posts” for passing places, lifting plans. Hand digging as required. Good lighting – but avoid erecting lighting towers in darkness.
Electricity
In designing electrical system consideration shall be made to the characteristics of the wind turbine generators and of the network to which the project is to be connected
And future access for maintenance?
Careful planning of each stage.
Component failure (mechanical, structural failure)
Early uncontrolled failure
Component failure (mechanical, structural failure)
Failure of:
gearbox, rotor blades, generator, controlling sensors, brakes,
Other components:
Coastal erosion; Atmospheric Area Corrosion: (Atmospheric Area = the area above the Splash Zone, which includes the turbine tower;
The Splash Zone (corrosion of equipment, including structural members, tower and equipment securing bolts, from waves and weather); The submerged area;
Constant functional check of the performance of the turbine. Upkeep of maintenance schedule
Component failure (mechanical, structural failure)
Component failure is entirely possible during the commissioning and testing phase in terms of similar failures in O&M. Failure may occur until functionality confirmed
Conduct pre-testing in a controlled environment. Commission to test schedule and assume that component or safeguard failure may occur until proved fully functional.
Component failure (mechanical, structural failure)
Component failure in lifting equipment assemblies, ground excavations and transportation equipment
Take care to ensure damage does not occur. Ensure all design criteria are met when assembling. Studies and clear guidance relating to connectivity of parts from different manufacturers should also be provided and strictly adhered to during the construction phase. Difficulties relating to plant compatibility arising during construction that is likely to affect integrity must be communicated to those undertaking commissioning and testing.
