High durability
Offshore wind farms utilise the power of the sea wind to generate clean energy. Installed far from the coast, they minimise visual disturbance and offer higher wind speeds. These turbines make a significant contribution to reducing CO2 emissions and are an important part of the energy transition. Offshore wind farms promise long-term economic and ecological benefits. There are challenges in terms of technical implementation and environmental protection, but the potential is enormous. They are a step towards a sustainable energy future.
The electricity generated by the wind farms undergoes a process of gathering, transformation and rectification before being transmitted through a High Voltage Direct Current (HVDC) line to the coast. To facilitate this process, transformers and rectifiers are employed at an offshore substation, requiring adequate cooling, often achieved through the use of seawater. In addition, all instruments used in this installation must be designed to withstand the harsh offshore conditions and strong electromagnetic fields that prevail in such environments.
Challenges
Measurement technology on offshore wind HVDC substations faces considerable challenges due to the extreme environmental conditions and technical requirements. One of the biggest challenges is corrosion resistance, as the devices are continuously exposed to salty air and seawater, which requires high-quality sealing and the use of corrosion-resistant materials such as stainless steel or special coatings. In addition, the measuring devices must be able to withstand extreme weather conditions such as strong winds, violent waves, UV radiation and large temperature fluctuations without losing precision.
Furthermore, the measuring devices must be resistant to electromagnetic interference that may originate from the electrical infrastructure of the wind turbine or other sources. Vibrations and mechanical loads caused by the operation of the wind turbines and the movement of the platform require shock- and vibration-resistant designs to ensure constant functionality. Long-term stability also plays a decisive role, as offshore turbines are difficult to access and maintenance work is complex and expensive. The devices must therefore work reliably over long periods of time.
How can KROHNE provide support?
As a measurement technology manufacturer, we provide comprehensive support for the operation of wind farms by offering process instrumentation designed to withstand the extreme conditions of offshore environments. Offshore power plants are constantly exposed to challenging environmental factors such as strong waves, high wind speeds, and corrosion from salty seawater.
Corrosion resistant sensor and converter options (316L)
To address these challenges, our corrosion-resistant sensors and converters, made from high-quality 316L stainless steel, provide exceptional durability and protection against corrosion. DNV GL approved versions tested for electromagnetic interference, vibration and environmental influences, compliant with NORSOK standards.
Flowmeters suitable for strong electromagnetic fields
Our flowmeters are also designed to perform reliably in environments with strong electromagnetic fields, ensuring consistent and accurate readings even in the presence of electrical interference.
High durability
Additionally, our instruments are engineered for long-term resilience, delivering highly accurate measurements even in the face of continuous vibrations, temperature fluctuations, and other environmental stresses. By providing precise monitoring and control, we help optimise the performance and efficiency of your wind turbines, reducing maintenance needs and contributing to the overall reliability of your operations.
