Extreme weather, heavy loads and remote locations are some of the challenges for wind turbines, requiring the highest level of reliability for the equipment to ensure the future viability of the wind energy market.
Aiming to increase the safety and reliability in slewing bearings, DNV GL works with stakeholders from across the industries to cooperatively decrease the damages in the field. The knowledge generated from this joint industry project (JIP) is planned to be ultimately incorporated in a DNV GL recommended practice or standard.
Spurred by lack of calculation concept
The JIP initiative was spurred by the realisation that the wind industry lacked a strong life-time calculation concept in this field, which carries a potential risk for future developments and investments. By developing a reliable calculation concept for slewing bearings, energy stakeholders will be able to work towards realistic operational lifetime estimations, offering the possibility of an efficient design process and a reduction of the manufacturing costs.
Furthermore, the risk for damages in the field is reduced and substantial operation and maintenance costs can be avoided in the future, which is an essential factor in the wind business.
Value for partners involved
Incorporating the experience and objectives of stakeholders along the wind energy value chain will add significant value for all parties involved. They will be able to contribute and influence the development of the calculation criteria to ensure their concerns are covered, practices are acknowledged and the objectives of all stakeholders are met. The involvement provides early access and insight into the results, ensuring participants are best prepared for its implementation.
Eight partners on board – more welcome
The JIP has been launched in Spring 2017 with a kick-off meeting including all selected partners coming from Siemens, Nordex, IMO, Liebherr, Laulagun, Statoil and Innogy.
The JIP is still in the development phase and more partners are invited to join. The project is not limited to wind turbines and is beneficial to other industries as well. Slewing bearings are also used in cranes and turret ships for example.
