DESCRIPTION:Offshore wind turbines offer promising alternative of harnessi
 ng the wind power in coastal regions where high population density and ass
 ociated economic and social factors obstruct use of suitable sites on land
 . High construction and grid connection costs of the offshore facilities a
 re offset by the higher quality of wind resources over sea and the install
 ation of large capacity turbines which\, consequently\, result with higher
  and cheaper energy production.\n\n \n\nDespite the advances and developme
 nts of quick and efficient offshore installation procedures market pressur
 es to reduce turbine cost and increase of long-term reliability continue u
 nabated. This particularly applies to the cost of supporting structure whi
 ch may account for up to 30% of the total cost of the offshore facility. W
 ith the rising price of steel in response to the construction boom around 
 the world there is a desire on the part of generation companies to diversi
 fy wind turbine construction market by improving massive concrete gravity 
 support structures.\n\n \n\nThis presentation discusses geotechnical chall
 enges associated with the construction and operation of concrete gravity s
 upport structures. Various aspects of the engineering design are discussed
 : scour protection\, seabed stability\, limit state based optimisation of 
 the support structure and the effect of supporting structure on the dynami
 c properties of a wind turbine. \n\n \n
