Abstract
A multi-channel swivel with the wear capability of rigid hard seal means by providing a single mandrel and multiple outer bodies to allow each body to have one or more seals inserted into one or both ends of each body, thereby allowing for three or more seal paths in the swivel.
Description
- Patent application titled “FLUID SWIVEL WITH COOLING PORTING” filed on the same date.
- N/A
- N/A
- The field of this invention is that of multi-port hydraulic swivels for the purpose of communicating high pressure liquids or gasses from a non-rotating location to a rotating location. The most common application is on the central shaft of a hose reel in which the central shaft of the reel rotates with the drum. The drum will be rotating as the hose is rolled out to its intended service. The pressure fluid supply to the reel will characteristically not be rotating, and therefore a rotating union will be required between the non-rotating fluid supply and the rotating main shaft of a reel drum.
- The importance of this type swivel has greatly increased as the drilling of oil and gas wells has moved to deep offshore waters. Drilling contemporarily occurs in 8,000 to 10,000 feet of seawater. In lowering the drilling system to these depths and in lowering certain completion and testing equipment, continuous pressure contact is desired to be maintained between the surface and the subsea equipment being lowered and/or operated. In some cases operational pressure is required as the equipment is lowered. In other cases, maintaining pressure on the system is a safety consideration. If the operator releases the pressure, the hose will become disconnected from the heavy package being lowered and allow the hose to be recovered. This is especially important if the heavy package becomes stuck on lodged in deep water.
- As greater depths are encountered and higher pressures are desired to be maintained as the reel and swivel are rotated. This higher pressure and the inherently higher number of rotations associated with deeper water depth cause specific problems with the swivels.
- A first problem is that a high degree of wear tends to occur in soft seals which can be inserted into machined grooves in the inner or outer surface of the mating parts. If a harder seal can be utilized at the higher pressures, a better or more extended wear life can be provided. An opposing pair of seals can be installed in the end of the outer body to a stopping shoulder and followed by a threaded gland to act as the opposing shoulder. On the other end of the outer body a second set of seals can be inserted to the opposite side of the central shoulder and again followed by a gland. This configuration can be utilized for a single or dual channel swivel, but there are needs for triple and quadruple channel swivels which cannot be serviced in this manner as there are only two ends to the outer body.
- A second problem is that the higher pressure and higher number of rotations generates heat. Heat generated on the outside of the seals disperses into the outer body which has progressively greater area as the distance moves away from the seals, and has a relatively large outer surface to dissipate the heat to the environment. The heat generated at the I.D. of the seal moves toward the centerline of the mandrel portion of the swivel, and literally runs into the heat generated on the opposite of the mandrel. The heat has no place to go, so it builds up to higher temperatures. The higher temperatures characteristically increase the friction, generating more heat at an even faster rate. In some cases we have seen, the heat gets so high in contemporary applications that the seals are actually cooked and fail.
- The object of this invention is to provide a multi-channel swivel which will allow for three or more channels with seals of a material which must be inserted into the end of the bore rather than being bent to allow insertion into a groove in the bore of the Outer Body or into a groove on the Mandrel.
- FIG. 1 is a partial section thru a subsea blowout preventer stack and a view of a reel in which a swivel of this invention would be used.
- FIG. 2 is a schematic showing how a swivel of this invention is used.
- FIG. 3 is a half section of a swivel of this invention.
- Referring now to FIG. 1, a blowout preventer (BOP)
stack 10 is landed on asubsea wellhead system 11, which is supported abovemudline 12. TheBOP stack 10 is comprised of awellhead connector 14 which is typically hydraulically locked to thesubsea wellhead system 11, multiple ramtype blowout preventers annular blowout preventer 17 and anupper mandrel 18. Ariser connector 19, and ariser 20 to the surface are attached for communicating drilling fluids to and from the surface. - Reel30 has a
frame 31,spool 32, and a swivel 33 mounted on the central shaft of the spool (not shown). Hose and/orcable reel 34 is shown going from thespool 32 of thereel 30 to acontrol box 35 on the subseablowout preventer stack 10. From thecontrol box 35, appropriate hoses 37 go to control various functions, such asram blowout preventer 16. - Referring now to FIG. 2, a reel schematic is shown. Spool32 is shown mounted on the
central shaft 50 which is supported by conventional bearings (not shown). On the left end of thecentral shaft 50 is mounted a swivel 51 having anouter body 52 and amandrel 53.connection 54 attaches the swivel 33 tocentral shaft 50. - Hydraulic lines60-63 are attached to the swivel
outer body 52 to deliver pressurized fluids to the swivel from the non-rotating hydraulic supply (not shown). Within the spool,line 70 connects withline 60 and exits themain shaft 50 and goes directly to thehose bundle 80 going to the ocean floor. This line is characteristic of the lines which need the pressure to be maintained during the rotating operations. Gage 81 is provided on this line to monitor the pressure in this line.Line 71 connects withline 61 and also goes directly to the hose bundle and is characteristic of a return line which would not require the high pressure during rotation.Line lines multi-valve panel 82 on theside 83 of thespool 32 for individual control of a multiplicity of lines to subsea equipment. - Stab
Plate 84 engagesreceptacle plate 85 to give individual hydraulic supply to various selected lines when the reel is not rotating.Control box 86 provides for operational control of thespool 32,failsafe brakes 87 provide stopping power for thespool 32,locking pin 88 provides positive position stopping for thespool 32, andmotor 89 provides operations power for thespool 32thru chain 90. - Referring now to FIG. 3, a half section of the swivel of this invention can be seen.
Inner mounting plate 100 is attached to themain shaft 50 bybolts 101.Outer mounting plate 102 is mounted to themandrel 103 bybolts 104.Outer mounting plate 102 is attached to theinner mounting plate 100 bybolts 105. - Mandrel103 is an cylindrical member with 8 seal surfaces 110-117 and locating
shoulders port 130,thru seal sub 131, drilledhole 132, and outport 133. Similar flow paths occur inports mandrel 103. -
Body 140 provides a central locatingshoulder 141, andend thread 143 which engaged by agland 144, and anend thread 145 which is engaged bygland 146. The space between the central locatingshoulder 141 and theglands seals - Similarly,
Body 160 provides acentral locating shoulder 161, and endthread 163 which is engaged by agland 164, and anend thread 165 which is engaged bygland 166. The space between thecentral locating shoulder 161 and theglands seals - The shoulder is indicated in the preferred embodiment to be a threaded gland. In practicality, lock rings, bolted flanges, and other style shoulder means can be used to achieve the goal of retaining the seals within the cavity. Literally, the end of the other body can provide the means to retain the seal within the cavity.
- In this way each of 2 bodies has provided a central shoulder and a gland on each end to trap 2 sets of seals each, for a total of 4 sealed ports. The
mandrel 103 has been made from a single piece of metal and provides a straight continuous flow path for the porting. The outer body is not continuous but is rather made of 2independent bodies bodies bolts 182 keep them attached together for rotary operation. In this way we can install four sets (pairs) of seals which are not amenable to deforming and insertion into grooves. This allows a single swivel to have 3, 4, or more channels of high pressure service. -
Port 190 is an air inlet port which can be used to flow air thruport 191 to allow for cooling of themandrel 103 of the swivel. Ports 200-204 provide for leak detection from the seals.Thread 210 provides for an anti-rotation means to stop the rotation of the bodies while the mandrel is being rotated. - In this way swivels with 3, 4, 5 or even more fluid channels can be provided.
- The foregoing disclosure and description of this invention are illustrative and explanatory thereof, and various changes in the size, shape, and materials as well as the details of the illustrated construction may be made without departing from the spirit of the invention.
