ABSTRACT:
A tension leg platform for supporting an oil rig above a seabed includes a deck, a buoyant hull and a single tubular tether. The tether has a lower end penetrating into the seabed and an upper end that is secured to the hull to hold the hull down against its own buoyancy. The deck is secured to the hull and adapted to support an oil rig. Multiple casing strings extend through the tether from the deck to the seabed. Supplemental buoyancy, tanks can be provided between the hull and the tether or within the tether itself.
