A modular offshore platform which can be used in a deep sea oil exploration is introduced here. A hybrid of guyed tower and tension leg platforms will be studied. A double-layer dodecahedrous float will be stabilized by a series of guyed cables and clump weights that are anchored to the ocean floor. The platform is built on a dodecahedrous float, which can be fabricated onshore and transported to the job site by direct towing. Buoyancy of the dodecahedrous float will counteract the tremendous weight exerted on this offshore structure. With the help of the guy cables and clump weights anchored to the ocean floor, the structure can be column stabilized to a designated location ready for needed drilling operation. Dodecahedron is one of the natural crystal forms which can be built up by modular space components. It is an ideal structure for easy assembly in a hostile, physically restrictive sea environment. In this article only the major factors affecting the analysis is considered. Much more detailed considerations will be required in the final design, reflecting environmental forces in action, stresses during erection, and the fabrication details.
