  Programme 
 
  Technical review for underwater infrastructure & underwater city of the future
  Presented By: Dr Tan Soon Keat
                             Director, NTU-MPA Maritime Research Centre
  To develop a new space creation approach – NEUSpace (New Underwater Space) to make use of the sea space to construct underwater infrastructure and at the same time use the top-side of the infrastructures as reclaimed land.
