Continued operation of wind turbines (WT)

At the present time, many older substructure achieve their proven service life of 20 years (design lifeWith a large number of wind turbines, re-powering (replacement by a new, larger system) is not possible due to new distance regulations. Therefore, further operation is the only option that prevents the wind turbine from being dismantled and allows further use. The BWE Study

Principles for the implementation of an evaluation and audit of the continued operation of wind turbines (BPW) on land from May 2017 takes up this topic in concrete terms and presents the basic procedure for the expert evaluation of the continued operation of a wind turbine by a recognized expert. This procedure is basically divided into

  • practical part
  • analytical part

The SKI Ingenieurges. mbH from Hanover is one of the experts listed with BWE and is also ö.b.u.v. SV for supporting structures of on- and offshore wind turbines. For this reason we are able to answer the question of a permissible further operation of a WEA by means of a expert opinion and to determine the further service life extending beyond the design life.
