ABSTRACT:
A deep water platform, suitable for use as a hydrocarbon exploration or production facility in very deep offshore waters, and a method of constructing the same are shown. The platform is positioned on top of flexible, buoyant piles made of large diameter, high strength steel tubing. A watertight bulkhead is located within the pile and the portion of the pile below is filled with seawater, while the portion above the bulkhead is substantially empty and in communication with the atmosphere. The bulkhead is positioned to cause the pile to have a predetermined net buoyancy so that the portion below the bulkhead, which is anchored to the seabed, is in tension. Bending members (trusses) are joined to the top of the pile and are connected to a plurality of neutral buoyancy tendons anchored to the sea floor. The tendons may be driven into the sea floor using a pile driver located within the tendons.
