Abstract
Methods and systems for controlling a stand-building process of which the method includes engaging a first tubular using an elevator, hoisting the first tubular by raising the elevator, lowering the first tubular into a spider by lowering the elevator, engaging the first tubular using the spider, disengaging the first tubular from the elevator after engaging the first tubular using the spider, engaging a second tubular using the elevator, hoisting and lowering the second tubular into engagement with the first tubular, connecting together the first and second tubulars, and disengaging the spider from the first tubular after connecting together the first and second tubulars. At all times during the stand-building process, a sequential step control system locks an open/close control of the elevator control, or locks an open/close control of the spider control, or locks both, depending on a step of the stand-building process being performed.
