Abstract
The present invention generally provides methods and apparatus for connecting threaded members while ensuring that a proper connection is made, particularly for premium grade connections. In one embodiment, a method of connecting threaded tubular members for use in a wellbore or a riser system is provided. The method includes the acts of operating a power drive unit, thereby rotating a first threaded tubular member relative to a second threaded tubular member; measuring the rotation of the first threaded tubular member; and compensating the rotation measurement by subtracting a deflection of at least one of: the power drive unit, and one of the tubular members.
