GE Renewable Energy and TÜV NORD have announced the first design conformity statement to cover a 40-year period. TÜV NORD issued the statement for GE Renewable Energy’s 2.7-116 turbine in accordance with the IEC 61400-22 standard.
The GE 2.7-116 onshore wind turbine from GE Wind Energy has a diameter of 116 meters, 56.9 meters long rotor blades and a hub height of 90 meters and generates an output of 2.7 megawatts. It is primarily designed for areas with strong winds. In issuing the Design Evaluation Conformity Statement, TÜV NORD conducts a thorough evaluation of the design of the wind turbine. This evaluation process includes, for example, the calculation of the turbine loads and the verification of the component design (rotor blade, mechanical components and structures, tower and internals). For the increased service life, the components are subjected to additional loads in line with the extended service life. In addition, ageing and wear as well as potential faults resulting from them are taken into account.
