Definitions

  • the stem S which extends upwardly from the top of the conical storage chamber C for supporting the drilling platform P above the surface of the water W is preferably a cylindrical structure formed in substantially the same manner as the laterally spaced multiwall construction of the cylindrical base B, including inner and outer skins and 111, which are provided with a lattice type network of supporting beams (not shown) similar to the diagonal supports 50 and 51 as well as transverse tension means, vertical, longitudinal and circumferential tension means for prestressing the stem structure prior to filling the area between the inner and outer skins 110 and 111, respectively, with concrete, grout or other suitable material.
  • Such drilling platform P is supported at the upper end of the stem S by a plurality of braces 120 which extend upwardly from a supporting ring 121 to the base 122 of such platform P.
  • the drilling ring D is shown positioned eccentrically of the stem S and the upper portion 125 of such platform P which rotatably supports the derrick D with regard to the base 122 so as to permit the drill pipe D that is supported in the derrick D to be aligned with each of the circumferentially arranged conductor guides 23 that are circumferentially spaced in the stern S.
