Abstract: A compliant concrete structure which is supported by using a compliant pile system consisting of piles and pile sleeves so that the platform may yield to large oscillations when the structure is installed in a body of water. The invention comprises attaching the pile sleeve guides (6) and the pile sleeves (3) to a rotation symmetrical concrete shell which forms the basic structure. The pile sleeves are rigidly connected to the lower end portion (2) of the structure.

Abstract: 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.
