ABSTRACT:
A method of supporting a structure, such as a drilling structure used in offshore oil activities. The structure includes a caisson having at least one ballast cell and a plurality of skirts extending downwardly below the base of the caisson. The skirts define compartments which are open at their lower ends. The structure is floated to a location at sea and is then sunk. Ballast is then introduced into the ballast cell to cause the skirts to penetrate downwardly into deeper layers of sea bed soil. The skirts thus form closed compartments. Sea water trapped within the compartments is then removed and ballast is then removed from the ballast cell to reduce the vertical load on the sea bed to a load level such that the sea bed material does not fail. Movement of the structure is primarily restrained by adherence and friction between the sea bed and the skirts and by temporary pressure differentials within the closed compartments created by partial movement of the structure.
