An automated pipe tripping apparatus includes an outer frame and an inner frame. The inner frame includes a tripping slips and iron roughneck. The automated pipe tripping apparatus may, in concert with an elevator and drawworks, trip in a tubular string in a continuous motion. The tripping slips and iron roughneck, along with the inner frame, may travel vertically within the outer frame. The weight of the tubular string is transferred between the tripping slips and the elevator. The iron roughneck may make up or break out threaded connections between tubular segments, the upper tubular segment supported by the elevator and the lower by the tripping slips. An automated pipe handling apparatus may remove or supply sections of pipe from or to the elevator. A control system may control both the automated pipe tripping apparatus and the elevator and drawworks.

Techniques and devices to assist an offshore unit in going on location and coming off location. A device may include an interface configured to receive a signal indicative of motions of an offshore unit. The device may also include a memory configured to store a set of values corresponding to acceptable motions of the offshore unit, as well as a processor configured to determine if a measured motion of the offshore unit exceeds at least one value of the set of values and generate an indication that going on location by the offshore unit can be undertaken when the processor determines that the measured motion of the offshore unit is less than or equal to the at least one value.
