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.

Abstract: Methods and apparatus for running tubulars into and out of a wellbore. A gripping apparatus is activated with an actuator having a primary actuator and a redundant safety feature. The redundant safety feature may include one or more redundant fluid operated pistons. The gripping apparatus may include an integrated safety system adapted to prevent damage to the tubulars while making and breaking out connections between the tubulars and the tubular string.

Abstract: Aspects of the present invention provide a tubular handling system for handling wellbore tubulars. In one aspect, the present invention provides a tubular handling system adapted to retain a tubular without damaging the outer surface of the tubular. In another aspect, the present invention provides a method of connecting tubulars by remotely controlling the connection process, including joint compensation, alignment, make up, and interlock. In one embodiment, the tubular handling system comprises an elevator adapted to support a tubular utilizing a first portion of an upset of the tubular and a spider adapted to support the tubular utilizing a second portion of the upset. In another embodiment, at least one of the elevator and the spider is remotely controllable. In yet another embodiment, the tubular handling system comprising a joint compensator system adapted to provide fluid communication to the elevator during rotation of the tubular.
