Abstract: The present invention relates to a wind turbine comprising a nacelle (1) installed on a tower (2) supported by a floating support. The nacelle is articulated with respect to the tower in a vertical plane, and it comprises means (12, 16) for correcting the nacelle tilt, means for automatically adjusting the correction means in accordance with sensors detecting the correction values, the adjustment means being synchronous with the movements of the floating support. Figure 4 to be published.

Abstract: A method of the invention provides improvement in the quality of coupled simulations between geomechanical and reservoir models by constructing a geomechanical model of an underground zone intended to be coupled with a reservoir model allowing simulation of fluid flows in the zone, from a geological model of the zone discretized by a fine grid. Geomechanical properties are associated with the various cells of the geological model on the basis of experimental data, the underground zone is discretized by a geomechanical grid with larger cells than the geological grid, and a scale change is applied to the geomechanical data included in the geological model in order to define equivalent geomechanical properties at the scale of the geomechanical grid of the zone.
