DMT provides a range of flexible solutions to enhance the efficiency, life span and safety of wind farms, all from one single source!
DMT is, among other things, a provider of systems for technical engineering services and measurement and control technology for industrial plants. We have extensive know-how in the development, and manufacture of measuring systems for monitoring the condition of rotary drive elements in various industries, including a proven system for wind turbine monitoring applications which is marketed under the name WindSafe®. Our diagnostic experts also offer an individual monitoring and reporting service.
Furthermore, the sensor our experts designed for measuring tower vibrations is currently installed in thousands of wind turbines around the world. In addition, a range of testing and safety related services round off DMT's spectrum for wind farm operators, ensuring your business is in safe hands.
DMT has decades of experience in engineering. As a member of TÜV NORD GROUP, Germany's leading technology service provider, we are known today around the world for innovative solutions and individualised consulting and support tailored specifically to the needs of our clients. The TÜV NORD brand stands for the highest level of quality and safety. We are also manufacturer-independent and have our own test centres and expert bodies.
Repairs, replacement parts and plant downtimes are expensive. With the right condition monitoring you can avoid unnecessary costs and save money - often several hundred thousand Euros!
DMT has more than 25 years of experience in this field and to date our condition monitoring systems have been used to record data from over 15,000 dynamic measuring points in various industries.
With our comprehensive drive technology know-how, we have developed a perfectly coordinated online CM system especially for the wind energy sector, based on structure-borne noise for early damage detection in the drive train of wind turbines.
With accurate, reliable data we can detect emerging damage and potential issues before they become problematic and in most cases diagnose the exact cause. This enables our experts to give clear recommendations for action, saving you valuable time and money.
Characteristics monitored by structure-borne sound include
This online system offers remote monitoring of individual wind turbines and whole wind farms in scalable service levels and can also be integrated into existing control systems.
Professional Condition Monitoring of Wind Turbine Components:
In addition to the hardware, we offer an inexpensive monitoring service based on VDI 3834. With our "Advanced Monitoring" you also receive specific service notifications and operational alarms from us, including documentation and recommendations for action. Regular automated analysis reports provide fast and simple visualization of the plant status at all times, so you are always in control of the situation.
By choosing our monitoring service, you entrust DMT with monitoring your wind turbines on a daily basis. The measured values recorded are compared with parameterised limit values for the monitored properties. The degree to which these limits have been reached is then displayed in an easy to read condition monitoring index. For a quick overview of the current status of all monitored components, the values are divided into classes that are color-coded from green to orange.
The current condition of the drive train, assessed according to VDI 3834, is recorded in monthly reports and automatically sent to the customer as a pdf-file. The report has a modular structure and shows the relevant information at a glance. If desired, other/further measured values can also be included and taken into account in the report. The stored data are available later, e.g. for more detailed analyses or for expert opinions.
Another option is our annual status report: we prepare a diagnostic report including a signal plot analysis and a detailed signal pattern description, for a whole year of operation. In the event of anomalies, e.g. changes in trend, or if a damage pattern is determined, our engineers will define appropriate measures for you.
DMT offers various sensors for the continuous detection of vibrations of wind turbine towers during operation. Specially developed for this purpose and stringently tested by our monitoring experts, these sensors are compact, inexpensive and easy to install. More than 5,000 of our KS22 sensors have been sold worldwide.
Exact information about the actual vibrations occurring on site also offers a good basis to optimize calculation methods for the construction of towers with regard to the eigenfrequency and requirements thereof. Thus higher towers can be built more cheaply. Moreover, tower vibration monitoring is a requirement of policies such as the GL2010.
We can also customise our sensors to your requirements. All of our sensors are developed and manufactured at the DMT headquarters in Germany.
From foundation right through to further operation - Our individual services and professional advice help you make the right decisions at the right time to get the best out of your windpark.
Geotechnics is a focal point of the DMT group's portfolio.
We offer comprehensive geotechnical services within the design, construction and installation phases of wind turbines according to international standards. This includes, among other things, the inspection of:
All of our assessments are concluded in a certification or conformity report.
Our building specialists are also on hand to monitor the foundation work during the installation phase.
Have you considered the fire protection of your wind turbines?
For decades, the DMT Centre for Fire and Explosion Protection has been developing comprehensive safety concepts for all kinds of industrial buildings that serve to implement relevant fire protection guidelines cost-effectively, efficiently and according to individual needs.
Right from the planning and construction phase of your wind turbine, it pays to consider necessary fire protection equipment and regulations. We can advise you on that. Our fire protection experts will also ensure that all fire safety technology is properly installed and approved. In addition, we can check the operational safety of your fire protection equipment at any time:
For all enquiries related to fire protection, please contact our specialist department:

On our test rigs, we are able to test the drive characteristics of a wide variety of mechanical and hydraulic components for industrial manufacturers and plant operators. Our main focus in this area is the testing of gears and gearboxes. For example, we carry out tests on transmission prototypes and end-of-line tests for series gearboxes. We not only test components of the wind turbines - DMT was also contracted by Siemens to perform functional and life time tests on jack-up gears for the world’s largest crane vessel, used for the installation of new offshore wind farms.
DMT also offers professional metrological consulting and further services in this field, including the application of strain gages for measuring mechanical stresses in structures and components.
Our engineers are happy to support the manufacturers of wind turbines and their components as well as transmission service companies with the following:
