Publication number: 20100080670Abstract: An elevator usable on a drilling rig is modified by attaching a swing arm and related structure to at least one accessory mounting provision on the elevator. The swing arm is tiltable to allow a single section elevator, carried by the swing arm, to engage a pipe extending near the well centerline. While the pipe section is being lifted, the swing arm pivots to allow the section to assume a vertical position under the elevator. When the pipe section is being rotated to run threads to join the section to the string the swing arm can extend to accommodate thread-run dimension changes. An elevator equivalent, without pipe gripping features, may be used.Type: ApplicationFiled: September 29, 2008Publication date: April 1, 2010Applicant: PREMIERE, INC.Inventors: Kris Henderson, Lee M.

Patent number: 7510028Abstract: Lower pipe stand racking combs are arranged to fold down from a side of the derrick at selected locations above the rig floor. In each racking comb an array of parallel fingers extend in a spaced array from a pivotable spine. The spine rotates to raise the fingers to a near vertical position to clear the rig floor activity area. A suspended pipe stand can pass laterally from the well center line past the ends of the fingers. The fingers, each, have a retractable extension that, when extended, will prevent the suspended pipe stand from passing the extended finger. The stopped pipe stand can then move transversely into the selected space between two fingers. Each finger extension has independent fluid power supply and control lines, the collection of the lines may extend to a control and power source selectively positioned on the rig floor or derrick. Raising of each comb assembly is, preferably, done by a fluid power cylinder attached to the derrick structure and to each comb assembly.Type: GrantFiled: August 24, 2006Date of Patent: March 31, 2009Inventor: Walter Thomas Welsh

Patent number: 6766860Abstract: An offshore drilling rig contains a heavy-duty support cart that straddles the moonpool and rides on rails. A funnel-shaped hole extends through the support cart, and a cutout on one side of the cart provides lateral access to the hole. The cart can be moved to the region of the rotary assembly, where a length of tubulars can be suspended from the cart. For instance, when the BOP is pulled out for installation of the Xmas tree assembly, the BOP and attached riser can be pulled up above the seabed and hung from the support cart, then moved laterally out of the way while the Xmas tree assembly is installed. This lateral movement lowers the possibility of collision between the BOP and Xmas tree assembly. The BOP assembly can then be disassembled and at a later time, or hung until is needed for an adjacent borehole. In a preferred embodiment, the cart is included on multi-activity rigs with more than one load path, hoist, and rotary assembly.Type: GrantFiled: February 22, 2002Date of Patent: July 27, 2004Assignee: GlobalSantaFe CorporationInventors: William G.

Patent number: 6361262Abstract: The present invention relates to a drilling vessel with drilling tower or drilling mast for drilling in the earth's surface from said vessel, for example for oil or gas. The drilling vessel according to the present invention is characterized by an auxiliary tower or mast placed next to the drilling tower or drilling mast, and a clamp carriage which is fixed so that it is movable between a first position near the drilling tower or drilling mast and a second position near the auxiliary tower or auxiliary mast, said clamp carriage having at least one gripping clamp for clamping the drill string. The presence of an auxiliary tower or auxiliary mast next to the drilling tower or drilling mast means that a substantial time gain can be achieved during the construction and dismantling of the drilling string.Type: GrantFiled: March 2, 2000Date of Patent: March 26, 2002Assignee: Huisman Special Lifting Equipment B.V.Inventor: Joop Roodenburg
