Problems solved by technology

Three are longer and therefore more difficult to handle due to their length and weight and the natural wave shape they create when moving
Additionally, accelerating the desired tripping rate increases risk

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 standfor 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 standsto/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 driveand a stand constrained by the clasp.
