Abstract
A clamping connector that can be remotely actuated and locked which is particularly useful in subsea applications for attaching subsea Christmas trees to marine wellheads. The clamping connector includes clamp halves linked by a locking stem. The locking stem is forced into a pre-stressed state by moving the locking stem from a first relaxed to a second pre-stressed position and retained in the second pre-stressed position by a locking collet. A locking collet through which the locking stem extends is moved from a first unlocked position to a second locked position wedged between the locking stem and one or the other of the clamp halves. When the locking collet is in the second locked position, it resists movement of the locking stem from the second pre-stressed position to the first relaxed position. The locking collet is then locked in the second locked position. The clamping connector of the present invention is characterized by a minimal height which is particularly advantageous over prior clamping connectors.
