ABSTRACT:
Tension leg platform system for use in drilling well bores into the floor of an offshore body of water. The system includes a buoyancy controlled vessel which is attached to anchors at the ocean floor by a series of pull down members. At the time of a well blowout, a detachably connected collar or anchor ring is guidably lowered from the vessel to the floor. Thereafter, a closure cap is drawn down to engage the anchor ring and thus permit escaping gas and crude oil to be directed through a conduit to the water's surface, where it can be collected.
