Patent number: 8720128Abstract: A method to disassemble a mast assembly having a substructure including a first and second section, a first and a second cylinder, and a lower mast section. The method includes the steps of disengaging a pair of front mast legs of the lower mast section from a pair of front leg supports. The pair of front leg supports are moved from an operational to a transport position. The lower mast section is lowered from a vertical to a horizontal position by retracting the first cylinder and the second cylinder. A mast center spreader is thereafter removed from the lower mast section. A center drill floor section is removed from between the first substructure section and the second substructure section so that a combination of the first substructure section, the first cylinder and a portion of the lower mast and a combination of the second substructure section, the second cylinder and a portion of the lower mast may be transported.Type: GrantFiled: October 1, 2012Date of Patent: May 13, 2014Assignee: Woolslayer Companies, Inc.Inventor: Dewayne G.

Patent number: 8695286Abstract: There is disclosed a telescopic mast (2) including two or more cylindric telescoping sections (4) with parallel walls (6), where the distal one of two adjacent telescoping sections (4) is narrower than the proximal one of the two adjacent telescoping sections (4), so that the distal telescoping section (4) can be moved into and out of the proximal telescoping section (4), respectively. In the interspace (8) between two adjacent telescoping sections (4) there is provided at least one device (10) interacting with an actuator (16) and pressing the adjacent walls (6) away from each other. Hereby play is eliminated or minimized.Type: GrantFiled: September 7, 2007Date of Patent: April 15, 2014Assignee: Falck Schmidt Defence Systems A/SInventor: Jan Falck-Schmidt

Publication number: 20140059949Abstract: A telescopic multi-mast system includes a plurality of telescopic masts, each of the telescopic masts having a plurality of telescopic mast sections. The telescopic multi-mast system also includes a drive mechanism for extending and retracting the telescopic masts. The telescopic, multi-mast system further includes a plurality of stabilisers disposed over the telescopic masts and connected to the mast sections of the telescopic masts to cancel angular deflection of the telescopic masts.Type: ApplicationFiled: September 6, 2012Publication date: March 6, 2014Inventor: Said Lounis

Patent number: 8661744Abstract: The present invention concerns a telescopic mast which at least includes one or more telescoping joints, where a telescoping joint is formed of two telescoping sections dimensioned so that one section can be moved into another section, where between each of the two adjacent telescoping sections in a telescoping joint there is provided at least one actuator urging the adjacent telescoping sections away from each other, where these actuators are disposed internally of the telescoping joints and offset at the internal periphery. By disposing actuators offset at the inner periphery of the telescoping sections, several advantages are achieved. The actuators are provided at a protected location, and the actuators may be designed with lengths that overlap each other when the telescopic mast is collapsed.Type: GrantFiled: April 15, 2008Date of Patent: March 4, 2014Assignee: Falck Schmidt Defence Systems A/SInventor: Lars Keller

Patent number: 8640388Abstract: A support structure for a rostrum includes a first A-frame; and at least a second A-frame, nestable and retractable into the first A-frame. The support structure may have an open central area and the second A-frame may be substantially the same as, but smaller than, the open central area of the first A-frame. At least one support means is connected to each A-frame for supporting a load, wherein the support is connected to an upper portion of one A-frame. The support extends from the upper portion of the one A-frame and is co-operable with an upper portion of another A-frame. The support structure may be telescopic and configured to be expandable and retractable between a retracted, stored position, and an extended, in use position.Type: GrantFiled: June 3, 2008Date of Patent: February 4, 2014Assignee: Steeldeck Industries LimitedInventor: Giles Favell

Publication number: 20130269268Abstract: Disclosed herein is a telescoping substructure of a drilling rig that includes first and second telescoping substructure boxes. The first and second telescoping substructure boxes each include, among other things, a lower substructure box and an upper substructure box that is adapted to be telescopically raised and lowered relative to the lower substructure box. Furthermore, each telescoping substructure box also includes raising means for telescopically raising and lowering the upper substructure box relative to the lower substructure box between a collapsed configuration for transportation and a raised configuration for drilling operations, wherein each of the first and second telescoping substructure boxes are adapted to facilitate movement of the telescoping substructure in at least one of a lateral direction and a longitudinal direction over wellhead equipment positioned above a wellbore location when the upper substructure boxes are in the raised configuration.Type: ApplicationFiled: April 16, 2013Publication date: October 17, 2013Applicant: National Oilwell Varco, L.P.Inventors: Jay John Thiessen, Kameron Wayne Konduc, Donald Leonard Burlet

Patent number: 8549815Abstract: Methods for connection parts of a mast of a drilling rig without using a crane or other lifting machine are disclosed. In certain aspects, these methods include moving parts of a mast to be assembled with trucks and positioning the parts with the trucks to facilitate their connection. This Abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b).Type: GrantFiled: February 29, 2008Date of Patent: October 8, 2013Assignee: National Oilwell Varco L.P.Inventors: Robert Benjamin Donnally, Chunqiao Ren, Stuart Arthur Lyall McCurdy, Xi Lin Liu, Hui Chun Sheng, Yan Yu

Patent number: 8534004Abstract: A rapid deployment and retraction telescoping mast system for controlling the height of a mast. A retraction mechanism including a resilient member, a retraction reel, a reel shaft, and a motor disposed about a frame. The resilient member extends from the retraction reel and is rigidly attached to a top tube of the mast through a sealed passage. The reel shaft rotates the retraction reel and winds the resilient member creating a retraction force on the top tube causing controlled retraction of the mast. A deployment mechanism including a compressor, storage tank, exhaust valve and isolation valve arranged about the frame and in communication with the mast. The compressor generates pressurized air to be communicated to the mast when the isolation valve is in the open position. The increase of pressure generated by the deployment mechanism provides a force within the mast thereby controlling its deployment.Type: GrantFiled: November 5, 2010Date of Patent: September 17, 2013Assignee: The Will-Burt CompanyInventors: Andrew Paul Wasson, Michael James Kardohely
