ABSTRACT:

The Atlantis artificial seabed concept is a new concept for cost effective drilling and field developments in deep waters, that has been developed over the last 4-5 years. This involves the use of a submerged buoyant "steel tank" that is installed at 200-400 meters below the sea surface, regardless of the actual waterdepth and that replaces the functions of the real seabed on which no equipment remains. In November 2001, the Atlantis concept was included in the Norway's government backed Demo 2000 Research Program. The Demo project includes fabrication and marine trials of a full scale Atlantis prototype unit. The marine trials are schedulde to take place in sheltered waters in Stavanger, Norway, in March / April 2003. The unit under fabrication has been designed for a potential use in 2000 meters water depth in West Africa.
