Monitor investment and avoid expensive repair
If you, as wind turbine owner, investor or operations manager, wish to monitor your investment and structure offshore, the foundation and the rest of the wind turbine should be monitored for example for loads, fatigue stress and corrosion etc.
Thus, you ensure that the wind turbine maintains its functionality, and you avoid large costs in connection with repair and retrofit.
Preventive or planned maintenance is the most often applied maintenance strategy in the offshore industry. If you apply this strategy in your wind farm, you would expect that the wind turbines maintain their functionality in the prescribed design life.
However, the wind turbine industry has experienced that this is not always the case. While other parts of the wind turbine often reveal flaws by coincidence, it turns out that it is different in the foundation.
Advantages of monitoring systems:
- Early warning of flaws so that you can act and correct in time, thus avoiding possible serious flaws in the structure.
- Detecting the cause of flaws so that you prevent future flaws, and avoid flaws in other similar wind turbine foundations.
- Use of data for corrective actions and for optimisation of sub-components and design.
- Online measurements of functionality of the cathodic protection,”CP”.
Monitoring contributes to design optimisation
The damage in this part of the turbine is often caused by unforeseen loads on the structure or external factors, which, unfortunately in some cases, have entailed very large and costly repairs. A monitoring and warning system in the foundation could have given notice of these serious flaws in time.
Monitoring systems can e.g. measure the following:
- Dynamic changes
- Mechanical displacement
- Functionality of ”CP”, cathodic protection
- Erosion of the sea floor, ”Scour”.
By installing a monitoring system in a couple of the foundations in an offshore wind farm, you get the opportunity, to systematically evaluate and assess the gathered data, either by manual collection of measuring data or by online monitoring. Perhaps your maintenance plan needs correction to maintain optimal operation, or maybe you need to act more drastically to avoid further damage in the turbine structure.
Operations data for this often-inaccessible part of the turbine is invaluable for both design optimisation and for the learning process in the conditions, which are applicable on the sea floor and at these depths.
Customer-specific monitoring systems
Monitoring systems are all customer-specific and in cooperation with you, we design and optimise a monitoring solution that is adjusted to your needs and wishes for information, and simultaneously agrees with your budget.
Further to the fact that FORCE Technology can design, supply and install unique monitoring systems for wind turbine foundations, we can also be of assistance with the subsequent data processing, evaluation, assessment and consultancy to those of our customers who do not have their own staff of internal specialists.
With our unique monitoring systems and our comprehensive specialist knowhow of materials types, corrosion, fatigue stress and expected life calculations, we are able to give you the best possible advice.
