Abstract: A foundation element, preferably for subsea use. The element consists of a number of open-bottom cells which are closed at their top and which are delimited by cell walls and comprise a common roof. The element is arranged to penetrate down into the sea bottom soil until the cells are filled with soil. The width of the element corresponds to or is in excess of the length of the cell walls.The roof of the foundation element, when said element is installed in the bottom strata, is essentially level with the sea bottom surface, thus constituting a high-quality seabed floor suitable for various loads.The invention also comprises the use of the element for various applications.
