Data-driven condition analysisFewer failures in offshore wind farms
Condition monitoring technology is revolutionizing the maintenance of slewing bearings in hard-to-access systems. Two experts from thyssenkrupp rothe erde explain the benefits.
Many of our customers want to optimize the operation of their systems over the course of their life cycle. To do that, they need data - for example, to manage machine loads. It is entirely conceivable that the service life of a slewing bearing could be extended by one or two years simply by adjusting the machine load by a few percentage points. But there is little point in even starting unless I know what effect this will have on wear in the slewing bearing. The data from the condition monitoring system is extremely valuable for addressing questions like these.
Data analysis always involves data security
Collecting and analyzing data that reflects the operation of an entire system also raises questions about data security. The condition monitoring solutions from thyssenkrupp rothe erde ensure the highest level of data security. Data is captured in real time and can be analyzed directly on site. It can also be transmitted wirelessly or collected centrally via a cloud service, for example. Data security remains the highest priority throughout.
Data analysis can reveal patterns that provide valuable insights into the operation of a slewing bearing. These findings help optimize the system. “This benefits both manufacturers and end customers of systems in which our bearings are used,” says Dr. Elfert.
More reliable offshore installations with maximum productivity
In summary, the condition monitoring solutions from thyssenkrupp rothe erde make it easier for manufacturers of offshore wind turbines and similar systems to plan maintenance work on slewing bearings. Data analysis also provides precise insights into wear and other important operating factors within the machinery. Any measures taken on the basis of these findings help make customers’ systems more productive, more efficient and less prone to failure. Continuous condition monitoring and data analysis are therefore essential for identifying patterns and maintenance requirements within an installation.
These solutions digitalize offshore installations and ensure that they receive the attention and best possible service needed to maintain a long service life and high performance - regardless of where they are located. Our experts also continuously refine and further develop the condition monitoring technology.
Predictive maintenance for offshore wind turbines
Predictive condition monitoring technology is revolutionizing the maintenance of slewing bearings in hard-to-access installations such as offshore wind farms at sea. We spoke with experts from thyssenkrupp rothe erde about the benefits of condition monitoring for manufacturers and end customers.
Dr. Gunther Elfert, Technical Project Manager, and Gideon Eichner, Commercial Project Manager at thyssenkrupp rothe erde, help wind turbine manufacturers operate their systems efficiently with a digital maintenance solution. Condition monitoring continuously tracks the condition of the slewing bearings in wind turbines - 24 hours a day, seven days a week. The data collected provides valuable insights into the operation of offshore installations, allowing maintenance work to be anticipated and planned more effectively. This helps reduce or even prevent potential wind turbine failures.
The thyssenkrupp rothe erde condition monitoring portfolio is therefore a predictive digital solution that uses intelligent technology to significantly increase the productivity and service life of offshore installations.
How condition monitoring and digital twins extend the service life of wind turbines
Installing condition monitoring in wind turbines means bringing them into the digital age. For offshore turbines in particular, customers are increasingly requesting a digital twin - an exact digital representation of the system - to achieve the best possible performance and keep their installations operating for as long as possible. Condition monitoring integrated into the slewing bearing provides the essential foundation for creating such a digital twin.
Our condition monitoring solutions
The thyssenkrupp portfolio of condition monitoring solutions includes ECMS® (Eddy Current Measurement System). ECMS® is an electrical method that uses eddy currents for non-contact material testing. The ECMS® from thyssenkrupp rothe erde is a sensor-equipped element that moves passively within the slewing bearing during normal operation. When an inspection is required, a service technician supplies external power to activate the sensors and data transmission for one complete revolution.
Another component of the condition monitoring technology offered by thyssenkrupp rothe erde is the ICM® system. Using various sensors, ICM® can record data such as bearing wear, movement profiles and temperatures and analyze it locally in real time. The data can also be made available through a variety of interfaces, including Wi-Fi and Bluetooth. This allows customers to be notified in good time when bearing maintenance or inspection is due.
