ABSTRACT:
An escape system for delivering personnel on a drilling rig to a safe location in the event of a blow out or other dangerous situation. More specifically, a personnel capsule is releasably maintained in an unbalanced disposition by an A-frame structure adjacent the racking board level of the derrick of an oil drilling rig. In the event of a blow out the personnel can enter the capsule and activate the release mechanism which will allow the A-frame to pivot outwardly away from the derrick. A control system is integrated with the A-frame and capsule to control their movement and to lower the capsule to a predetermined safe location.
