Abstract:
A high trip rate drilling rig has first handling equipment to transport stands in/out of setback, second handling equipment to deliver stands to/from well center, and a hand-off position to set down stands for exchange between first/second equipment. Second equipment can include a top drive and a delivery arm translatable along the mast past each other, and a clasp on the arm slidable on the stand for constraint below the upper end, which can allow the top drive to engage/disengage the constrained stand above the arm. A high trip rate method transports stands in/out of setback, delivers stands to/from well center, and sets down and hands off stands at hand-off position between the setback transportation and well center delivery. The delivery can include engaging/dis-engaging the top drive and a stand constrained by the clasp.

Claim (Index 124):
The method of  claim 98  to remove tubulars from the drill string, comprising:\n (1) engaging a clasp [ 550 ] of an extended tubular delivery arm [ 500 ] with an upper portion of one of the tubular stands connected to the drill string engaged in a rotary table [ 810 ]; \n (2) disconnecting the one tubular stand from the drill string; \n (3) retracting the tubular delivery arm to move the one tubular stand away from the well center position; \n (4) translating the tubular delivery arm along the mast to lower the one tubular stand; \n (5) rotating the tubular delivery arm to face the stand hand-off position; \n (6) extending the tubular delivery arm to move the one tubular stand into the stand hand-off position; \n (7) securing the one tubular stand in the stand hand-off position; \n (8) releasing the one tubular stand from the tubular clasp and retracting, rotating, extending, and translating the tubular delivery arm along the mast to return the clasp to the upper portion of a next one of the tubular stands connected to the drill string engaged in the rotary table; and \n (9) repeating (1) to (8) for the next one tubular stand.
