ABSTRACT:
A tension-restricted articulated platform tower for offshore oil and gas production. Two or more tower segments of increasing lateral dimension (proceeding toward the ocean floor) are stacked and articulated by means of a resilient joint. The platform tower behaves as a fixed tower under normal quiescent conditions with each of the segments above the base segment sitting thereabove in an at rest position. When forces sufficient to unseat the compressed resilient joint element are directed against the platform tower (e.g., from wind, waves, or water current), the tower behaves complaintly with tension elements secured to each corner post providing a restorative force proportional to the amount of tower movement.
