A deep water support platform, suitable for use as a hydrocarbon exploration
or
production facility in very deep waters of 10,000 ft or more is presented. The
platform is attached to the floor of the ocean with a buoyant pile that includes
buoyant members attached about the periphery of the pile. The buoyant pile and
buoyant members include tubular members that can be filled with water, oil, air
or other materials to produce a structure that has improved buoyancy and stability
over prior platforms. Embodiments include configurations of buoyant members that
have constant and equal diameter and spacing, and other configurations where the
diameter and/or spacing of the buoyant members changes along the pile. In addition,
the buoyant members are arranged about the pile to reduce vortex induced vibrations
on the platform by interfering with current flow about the support structure.
