A compliant pile system for supporting the vertical weight of a guyed tower structure installed in a body of water. The pile system is comprised of at least one pile element which in turn is comprised of a pile jacket and a pile member. The pile jacket extends from one point in the structure to a second point which lies above the first point and is attached at only one point to the structure. The pile member passes through the pile jacket and is forced into the marine bottom and is attached only at its upper end to the pile jacket. In one modification, the pile jacket is comprised of an odd number of concentrically positioned sleeves with the pile member being affixed to the top of the innermost sleeve and the outermost sleeve being affixed only at its bottom to the structure. The sleeves, if more than one, are attached to each other at their respective alternate ends. In another modification, the pile jacket is comprised of an even number of concentrically positioned sleeves with the pile member being affixed only at its upper end to the innermost sleeve and the outermost sleeve being affixed only at its upper end to the structure. The sleeves themselves are connected together only at alternating respective ends thereof. By constructing and affixing the pile jacket as described and affixing the pile member thereto only at its upper end, the effective length of the pile element is increased and its axial stiffness is reduced.
A compliant pile system for supporting the vertical weight of an offshore structure of the type which extends between the marine bottom and the surface of a body of water, said system comprising:
A compliant pile system for supporting the vertical weight of a guyed tower structure of the type having a main truss member which extends between a marine bottom and the surface of a body of water and a plurality of guylines extending between said main truss member and said marine bottom to maintain said truss member in a vertical position, said pile system comprising:
