摘要： An improved pipe wiping device is set forth which incorporates from an upper end fishing neck, a threaded connection for a central mandrel and multiple pipe wiping elements which are formed of flat resilient sheet material cut in circular fashion and having notches therein. The pipe wiping elements are alternately spaced so that the notches in the pipe wiping elements are overlapped above or below by protruding pipe wiping elements. Enlarged and elongated spacers are positioned between adjacent pipe wiping elements. The central mandrel terminates at a flexible coupling formed of resilient material or a spring. It then connects with a buoyant chamber there below to cause the device to float in the drill mud in the pipe string as the pipe string is pulled from the well borehole.

摘要： The rat hole assembly includes a rat hole comprised of a casing large enough to receive a kelly used in drilling of a well. The casing is perforated to permit passage of fluid when inserting or withdrawing the kelly, thus avoiding a piston effect. The rat hole is free at its upper end and includes a releasable pivot connection and support or anchor assembly at its lower end so that the upper portion of the rat hole can be swung adjacent to the rotary table used for drilling for insertion of the kelly into the rat hole and withdrawal of the kelly from the rat hole in normal drilling operations, and the rat hole, either with or without the kelly in it, can be swung over to an out of the way position when not in use.The releasable pivot connection and support or anchor assembly preferably includes a "J" slot assembly having a pair of protective outer plates connected to a structural member and includes inner "J" slot plates. A stabber of a size to move within the inner "J" slots plate is connected to the lower end of the rat hole and includes a pin extending transversely from each side which is movable in the "J" slots.The arrangement is such that the rat hole will not be inadvertently released from the support during normal drilling operations and storage; however, the rat hole can be released readily from the anchor when desired.

摘要： A releasable and retrievable mooring system for vessels is disclosed which includes anchors and anchor chains each having an explosive link arranged to separate the anchor upon detonation, a transponder operable from the vessel to send acoustic signals and receivers secured to the links to detonate them, a marker buoy having a line to either or both the anchor or anchor chain downstream but adjacent to the link, and a stopper upstream but adjacent to the link to prevent the link end of the anchor chain from falling into its locker when reeled in. The marker buoys either float on the water's surface or are submerged and releasable to the surface. Each includes retrieving lines extending to the anchor chain adjacent but downstream of the link or to the link. When using floating buoys, the retrieving lines are attached to strippers slidable on the anchor chains which includes stripper stoppers to limit travel of the strippers. Detonation of the link frees the vessel from the anchors for movement off of location and in repositioning the vessel on location, a workboat moves the previously retrieved portion of the anchor chain to the location of its anchor marker buoy, retrieves the submerged portion of the anchor chain by hoisting the line connected to it, and then reconnects the sections of the chain by reconnecting the explosive link. Other details, features and advantages are disclosed.

摘要： A system for testing and installing a blow out preventer on a floating vessel and offshore drilling rigs, although the system may be used on other rotary drilling rigs, is disclosed. Retractable rotary table supporting beams are disposed over the moon pool and the rotary table is releasably connected to them. Retractable sub-structure beams are provided below the rotary table so that means provided to move the assembled blow out preventer can move it through an opening in the derrick and over the moon pool when the rotary beams are retracted. Retractable moon pool skid beams are provided which support the blow out preventer when skidded through the moon pool opening in the sub-structure.In one aspect of the invention, the means connecting the rotary table to its support beams are self-aligning to that once the rotary table is aligned it can be removed and replaced without any further alignment. Also, support shoulders are provided on the main blow out preventer and lower riser section thereof which engage and are supported by the moon pool beams, so that the rotary support beams, rotary table and sub-structure support beams can be replaced and the blow out preventer hooked up to the riser, drill string or casing, the moon pool beams retracted and the blow out preventer lowered in the moon pool to the sea floor.

摘要： A mooring system is disclosed for maintaining a ship shape drilling vessel within alignment limits and for warping it into the sea while drilling a well from the vessel in the sub-surface ground below it. The mooring system absorbs all of the forces on the vessel, such as wind, current, wave, swell, roll, pitch, heave, surge and sway. These forces are measured by sensing load on a motor, electric, hydraulic, and the like, driving the anchor chain wildcat while hauling it in, by sensing load on the brake bands for the windlass wildcats, and by sensing load on the chain stopper, which sensed loads are transmitted to a display device which provides sufficient information to maintain the drilling vessel within the alignment limits and to warp it into the sea to minimize forces and motions of the vessel and to avoid beam sea forces. Preferably, a chain counter is provided on the power wildcat which counts the links, and hence the distance, the anchor chain is payed out or hauled in, which is transmitted to the display device. The anchor chains extend from each side both fore and aft of the vessel and each anchor chain has an electric motor driven wildcat, and extends through a chain stopper and fairlead. Vessel alignment is displayed on a cathode ray tube using an acoustic position resonance system.
