Abstract: A method and system certifies a joint between a first threaded element having a first shoulder and a second threaded element having a second shoulder and the equipment used to tighten the connection. The method tightens to a first position at which the first shoulder abuts the second shoulder. Marks are made that are aligned across the first element and the second element corresponding to the first position. The connection is loosened and then tightened to a second position complying with a predetermined tightening specification. The distance beyond the marks for the first position is measured to verify that it is within acceptable tolerances. If acceptable the connection and/or the tightening equipment can be certified.

Abstract: A control system for a well site, the well site includes connectable elements configured for inserting down a well. An explosion hazard zone surrounds the well site. A first electronics enclosure is remote from the explosion hazard zone and houses a first electronics module. A remote electronics control module is spaced apart from the first electronics housing and a remote hydraulics module removed from the first electronics module and the hazard zone module. The control system includes a human machine interface including a display and input. A central communications module is in wireless communication with the first electronics control module, the remote electronics module, and a remote location. A processor is in one or more of the first electronics module, the communications module or the human machine interface.

Abstract: A pressure accumulator control system for a blowout preventer includes a programmed logic control, a plurality of remote valves and a pressure monitoring and recording system. The control system monitors: accumulator pressure; valve manifold regulated pressure; annular regulated pressure; individual bottle manifold pressure; air operation pressure; nitrogen back-up system pressure; or open or closed function lines.

Abstract: A renewable bearing is for a tong including a housing and an engagement assembly. The bearing has a monolithic upper bearing element having a substantially planar upper surface and a monolithic lower bearing element having a substantially planar lower surface. The upper and lower bearing elements are configured to mount inside the housing with a substantially same outer horizontal profile as the upper bearing element. The upper bearing element and the lower bearing element define a central open area. The upper bearing element and the lower bearing element have an inner section define a radial recess opening to the central opening and for receiving the engagement assembly. The upper bearing element and the lower bearing element have outer sections that form a bearing portion radially intermediate the engagement assembly.

Abstract: A method and system certifies a joint between a first threaded element having a first shoulder and a second threaded element having a second shoulder and the equipment used to tighten the connection. The method tightens to a first position at which the first shoulder abuts the second shoulder. Marks are made that are aligned across the first element and the second element corresponding to the first position. The connection is loosened and then tightened to a second position complying with a predetermined tightening specification. The distance beyond the marks for the first position is measured to verify that it is within acceptable tolerances. If acceptable the connection and/or the tightening equipment can be certified.

Abstract: A system for monitoring loads at well drilling and service operations includes a digital user interface. The digital interface is in electronic communication with a first pressure transducer in fluid communication with a first pad type hydraulic load sensor, a second pressure transducer in fluid communication with a second pad type hydraulic load sensor, and a third pressure transducer in fluid communication with a hydraulic diaphragm type deadline load sensor. The digital user interface module functions to monitor the hydraulic pressures experienced at each pressure transducer and functions to calculate and display a corresponding weight load in numerical and graphical form for each pressure transducer. The digital user interface is also in electronic communication with a fourth transducer in fluid communication with a hydraulic power tong unit.

Abstract: A tong assembly includes a case assembly having an enclosure defining an interior. A bearing assembly is disposed in the interior of the enclosure. The bearing assembly includes a first bearing member defining a first cavity and a second bearing member defining a first cavity. A tong head assembly is disposed in the interior of the enclosure of the case assembly. The tong head assembly includes a tong head engaged with an outer ring gear.
