High trip rate drilling rig

Abstract

A drilling rig system for obtaining high trip rates separates the transport of tubular stands in and out of their setback position into a first function, delivery and retrieval of tubular stands in well center position as a second function; and the functions intersect at a stand hand-off position where tubular stands are set down for exchange between tubular handling equipment. A drilling rig has a tubular delivery arm that vertically translates the mast in a non-conflicting path with a top drive. The tubular delivery arm is operable to deliver tubular stands between a catwalk, stand hand-off, mousehole, and/or well center positions. An upper racking arm moves tubular stands between a racked position in the racking module and a stand hand-off position between the mast and racking module. An upper support constraint stabilizes tubular stands at the stand hand-off position.
