Abstract
A temporary abandonment cap includes a body, a pressure-retaining top portion extending across the body and a plurality of locking pins coupled to the body and a single moveable handle, the locking pins being adapted to be moved from an engaged position to a disengaged position by movement of the single handle. The temporary abandonment cap is lightweight, reusable, and can be placed on and retrieved from an open pipe of a subsea well.
