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/disengaging the top drive and a stand constrained by the clasp.
