Removal of old monopiles

At the end of a wind farm’s lifetime, everything has to be removed. Current practice is to cut the monopiles that support the wind turbines several meters below the seabed. In the second Hydraulic Pile Extraction Scale Tests (HyPE-ST 1.2) project, Anderson Peccin da Silva and Alba Rodríguez Piedrabuena, both from Deltares, are investigating a new hydraulic pile extraction technology. In ‘Under pressure’, they tell you more about this promising decommissioning technology.
