Parking device for blowout preventer
First Claim
1. A parking device for a blowout preventer mounted for movement aboard a floating drilling station, the device comprising:
- a parking frame adapted to hold the blowout preventer with the center of gravity of the blowout preventer lying above the points at which the blowout preventer is supported on said parking frame, said parking frame at its lower portion is equipped with a testing block upon which the blowout preventer can rest, thereby allowing functional testing of the blowout preventer in a non-installed position; and
control drive means for moving the blowout preventer as a unit back and forth between a parked position and an installed position for utilization on the drilling station, said control drive means including first drive means for raising and lowering said parking frame and second drive means for moving said parking frame sideways.

Abstract
A parking device for containing a blowout preventer aboard a floating drilling station. The parking device includes a parking frame which is capable of holding the blowout preventer with its center of gravity lying above the points at which the blowout preventer is supported on the parking frame. The blowout preventer can be moved as a unit back and forth between a parked position and an installed position for utilization on the drilling station. For enabling such movement a first drive mechanism is provided for raising and lowering the parking frame and additionally a second drive mechanism is provided for moving the parking frame sideways.
