DESCRIPTION:Offshore wind is expected to play a major role in the future o
 f renewable energy. To meet its target that 15% energy be produced from re
 newables\, the UK government aims to construct 7\,000 turbines that will g
 enerate 33GW of energy. Offshore wind turbines often use large diameter mo
 nopiles as foundations. These monopiles must be designed both to support t
 he vertical and lateral loads of the turbine and to provide sufficient sti
 ffness to prevent system resonance. When these foundations are installed i
 nto clay\, there is a significant potential for the performance of these p
 iles to change over time due to the cyclic loading applied by the turbine.
  Centrifuge testing of scale model monopiles in overconsolidated speswhite
  kaolin was carried out to investigate the monopile's lateral behaviour an
 d asses the change of stiffness under cyclic loading. Based on the results
 \, recommendations were developed to optimise and improve foundation desig
 n for long-term performance.
