LONG BUOYANT FLEXIBLE PILE FRAMES FOR SUPPORT OF DEEPWATER OFFSHORE PLATFORMS

This paper is about Long Buoyant Flexible Pile Frames for support of deep-water offshore platforms. These Long Buoyant Flexible Pile Frame structures combine elements of bottom-founded and floating systems. They consist of one or more piles (legs) rigidly connected to bending members (trusses) at the sea floor, and also near their upper ends below or above the water surface. The piles are large-diameter steel cylinders. There is a watertight bulkhead in each pile with the pile open to water below the bulkhead and open to the atmosphere above the bulkhead. The buoyancy of the piles supports the structure plus the payload. Overturning moment caused by wind, wave and current is resisted by the buoyant force offset horizontally from the anchorage and from bending induced at the top and bottom of each pile by the bending members.
