A tension leg caisson is disclosed for supporting surface facilities on a deck for conducting hydrocarbon recovery operations in deepwater location applications. The tension leg caisson has an elongated, buoyant central vertical column or caisson with a plurality of outrigger pontoons. A plurality of tendons are connected on one end to the outrigger pontoons at a location which is spaced apart from the vertical. The other end is anchored to the ocean floor. Another aspect of the invention is a method of improving the dynamic response of a buoyant central caisson type platform.
