<p>A deep water platform (100), 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 a plurality of flexible, buoyant piles (10) made of large diameter, high strength steel tubing. A watertight bulkhead (15) is located within the pile and the portion (20) of the pile below is filled with seawater, while the portion (30) above 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 (50) is in tension.</p> |
