20140150719 | DEVICE FOR CLEANING AND DOPING EQUIPMENT FOR THREADS - A device for cleaning and doping (lubrication) equipment for threads of the type used to join pipes to a pipe string, especially in connection with petroleum production, where cleaning fluid and dope (lubricant) are sprayed at the threads at relatively high pressure from at least one nozzle mounted in the rotatable make-up section of a power tong, and where at least one injection pump arranged to supply cleaning fluid or dope to the at least one nozzle is located in the rotatable make-up section. | 06-05-2014 |
20140166299 | ARRANGEMENT IN A HOSE CONNECTION BETWEEN A WELLHEAD AND A SURFACE INSTALLATION - Arrangement in a hose connector of a riser provided between a wellhead and a floating surface installation. One or more hoses form a flexible fluid communicating connection between an upper portion of the riser and the floating surface installation. The first end portion of at least one fluid conduit is fixed to the riser by an upwardly directed, first pipe muzzle and is provided with a rotatable connecting sleeve. Each of one or more flexible hoses is connected to a conduit spool of a connecting assembly provided with a second and pipe muzzle that is arranged for releasable mating with the first end portion of the fluid conduit. A lifting yoke is connected to the connecting assembly and forms an actuator which is able to effect rotary motion to the connecting sleeve to enable engagement. | 06-19-2014 |

20140174829 | DEVICE FOR A TOP DRIVE DRILLING MACHINE FOR CONTINUOUS CIRCULATION OF DRILLING MUD - A device for a top drive drilling machine, in which a drive shaft, which is arranged for releasable connection to a drive and to a first end portion of a drill pipe, is provided with a centre bore extending therethrough and arranged for fluid communication between the drilling mud plant and a fluid bore in the drill pipe. First and second releasable, drive-shaft-surrounding, respectively drill-string-surrounding, pressure seals and a valve which is arranged to provide, in an open position, a passage for the drill pipe or drive shaft, form a first and a second chamber. A drilling mud inlet is arranged for the second chamber and is arranged for fluid communication between the drilling mud plant and connection housing. A method for the continuous supply of drilling mud to a drill string by the use of the drilling machine. | 06-26-2014 |
20140216817 | SLIP DEVICE FOR SUSPENDING A DRILL OR CASING STRING - An apparatus for gripping a cylindrical member is provided. In one embodiment, an apparatus includes a clamping device having clamping dies that enable the clamping device to grip a tubular string. The clamping dies have clamping faces configured to adapt to curvature of the tubular string when the clamping dies engage the tubular string via the clamping faces to facilitate use of the clamping device with tubular strings of different external diameters. Additional devices, systems, and methods are also disclosed. | 08-07-2014 |
