Mesure de subsidence dans le domaine marin

Abstract : Subsidence is a phenomenon that is increasingly encountered in the oil industry and elsewhere. In order to anticipate the consequences that this can cause both on the surface and on the seabed, it is necessary to measure it. This measure is most often made in the long term because it is a slow and progressive phenomenon. In this final work, we propose two subsidence monitoring methods : GNSS PPP on the surface and measurement by pressure sensors for deepwater. Both methods were evaluated using two case studies. At the end of our treatments, we are able to guarantee the accuracy of each method.
