United States Patent 3,190,397 HOSE REEL AND HOSE SUPPQRT SYSTEM Douwe de Vries, Metairie, L11. assignor to Shell Oil (Zornpany, New York, N.Y., a corporation of Delaware Filed Dec. 3, I962, Ser. No. 241,693 8 Claims. (Ci. 13735'5.1'7)

This invention relates to a hose reel system and pertains more particularly to a hose reel adapted to reel simultaneously a plurality of hoses as well as means for suspending long lengths of hoses from a floating vessel positioned at the surface of a body of water.

During recent years, the continued search for oil has resulted in developing methods and apparatus for drilling underwater wells at locations where the water may range from 100 to 1500 feet or more in depth. In these locations it is customary to position a wellhead assembly at a considerable distance below the surface of the water, preferably on the ocean floor, so that it is not a hazard to the navigation of ships in the area. One method of drilling and completing underwater wells in this manner is described in copending patent application, Serial No. 830,538, filed July 30, 1959, and entitled Underwater Well Completion Method.

In well drilling operations wherein the wellhead assembly is positioned below the surface of a body of water, various pieces of equipment such as wellhead connectors, blowout preventers, etc., are lowered from a vessel on the surface of the water to the underwater wellhead assembly where they are remotely connected. One method of connecting various pieces of equipment together at an underwater wellhead assembly is to employ electrically or pressure-actuated components which may be sealed or locked together by applying power or fluid pressure to th components from the remotely-located vessel. For example, in the event that pressure-actuated connectible components are employed, the component would have one or two hydraulic hoses connected to it when it was lowered from the vessel to its position on the wellhead assembly with the pressure hoses extending to the vessel where they could be connected to the source of fluid pressure.

The use of pressure hoses or current-conducting cables between the drilling vessel at the surface of a body of water and an underwater wellhead assembly poses several problems. In deep-water locations extreme lengths of pressure hose could not be hung from the vessel as they would pull apart under their own weight unless reinforced with steel or in some other manner. Additionally, when a large number of components are used on the underwater wellhead assembly this results in numerous cables extending to the vessel on the surface. In one well drilling installation, 27 separate pressure hoses extend simultaneously between the wellhead assembly on the ocean Provision must be made to prevent these numerous pressure hoses from becoming entangled due to wave action and underwater currents. At the same time the pressure hoses have to be grouped together for ease of handling as certain components of the wellhead assembly are removed and pulled back to the drilling vessel. In one installation 27 pressure hoses were divided into three bundles of 9 hoses each. Each hose bundle was about 8 inches in diameter and very cumbersome to handle on the deck of the vessel when it was necessary to pull say, 300 feet, of the cable back to the vessel. In attempting to put a bundle of hoses on a hose reel it often happens that one or more of the hoses becomes crushed. Likewise, if the hose bundles are allowed to hang free in the water the currents often cause them to rub against underwater structures and wear out.

It is therefore an object of the present invention to provide a hose-reeling apparatus on which a plurality of hoses may be simultaneously reeled and/ or stored.

A further object of the present invention is to provide a hose-reeling apparatus adapted to store a plurality of hoses and providing simple means for establishing fluid communication with the ends of the hoses that are Wrapped close to the drum of the hose reel.

Another object of the present invention is to provide cans for supporting a plurality of pressure hoses or electrical conduits of considerable length as they depend from a drilling vessel positioned at the surface of a body of water.

Still another object of the present invention is to provide a hose-reeling apparatus including hose suspension means which may be readily connected or disconnected from a plurality of hoses as they are reeled in and stored on a hose drum.

A still further object of the present invention is to provide a hose-reeling apparatus and hose suspension means adapted to suspend a plurality of hoses in side-by-side arrangement in a manner such that all hoses are subjected to the same stresses in reeling and do not become entangled when subjected to wind, waves or ocean currents during the drilling of oil wells at offshore locations.

These and other objects of this invention will be understood from the following description taken with reference to the drawing, wherein:

FIGURE 7 is a detailed view taken in partial longitudinal cross section showing the connections between the hoses on a hose drum and the permanent conduits formed thereon.

Referring to FIGURE 1 of the drawing, a drilling vessel, barge or platform 11 of any suitable floating or floatable type is illustrated as floating at the surface of a body of water 12 while being substantially fixedly positioned over a preselected well location by suitable vessel positioning means well known to the art or by being anchored to the ocean floor 13 by anchor lines 14 and 15 running to anchors (not shown), Equipment of this type may be used when carrying on well drilling operations or well Wonk-over operations in water varying from about feet to 1500 feet or more in depth. The drilling vessel is equipped with a suitable derrick 16 containing a fall line system 17 and other suitable auxiliary equipment needed during drilling operations. In addition, the vessel 11 is provided with one or more hose reels 18 from which a plurality of pressure hoses or electrical conduits '19 extend downwardly through the body of water. A suitable source of pneumatic, hydraulic or electric power 2.0 is also provided on the vessel 11. The derrick 16 is positioned over a drilling slot or well 22 which extends vertically through the barge in a conventional manner. When using the equipment of the present invention, the slot 22. in the vessel 11 may be either centrally located or extend in from one edge. Alternatively, drilling ope-rations may be carried out over the side of the vessel without the use of a slot. For'example, the drilling vessel may be provided with a deck portion which, overhangs the hull of the vessel.

One form of an underwater wellhead assembly is illustrated in FIGURE 1 as comprising a base plate 2 3 which is fixedly secured to a well casing 24 which in .turn is positioned in a'well drilled in the ocean floor 13- and preferably cemented therein. The base 'plate2'3 is provided with a plurality of upwardly-extending guide columns 25 and'26 which are adapted to receive and center on the well casing 24 various pieces of equipment such as a wellhead connector 27, a blowout preventer 28 and a landing head 29 at the lower end of marine conductor pipe 30 through which. drilling operations are conducted. The marine conductor pipe extends up-wardly through the slot 22 in the vessel 11. Each of the

wellhead components

27, 28 and 29 are provided with a pair of pressure hose-s which are bundled together to form the hose bundle 19 extending to the vessel at the surface.

One form of a hose reel is illustrated in FIGURE 2 which comprises a base member 31 adapted to be secured as by bolting to the deck of the vessel 11 (FIGURE 1). Welded to the top of the base plate 31 are a pair of side support members 32 on which a bearing 33 is mounted. An axle 34 rotates in the bearing 33 and serves as a mounting for the reel 18 which comprises a hose drum 35 with side plates 36 which extend radially therefrom a substantial distance to increase the capacity of the drum. The hose reel 18 is provided with any suitable type of prime mover means such for example as a motor 37 hav- :ing controls 38 for driving the drum 34 in one direction or the other. Extending laterally through the side wall 36 of the drum are a series of fittings 40 which in essence form one portion of a hose coupling so that hoses, for example hoses '41 and 42, can be connected to a pair of the couplings 40 outside the drum when the drum 35 is in a stationary position. Obviously, as in all hose reel systems, the drum 35, is provided with suitable brake means 35a, stop means or drum blockingtmeans for preventing movement of the drum 35 when the

hoses

41 and 42 are connected to the outside thereof. If; itis desired to move the. drum 35 to allow more hose to be reeled oif or reeled on, the hoses 41 and 42' would be disconnected temporarily. The hoses 41-and 42 would extend to a suitable sourceof fluid pressure onboard the vessel 11. In the event that the

conduits

41 and 42 were electrical conduits, a generator could be employed as a source of power.

As shown in FIGURE 4, a pair of

hose reels

18 and 18a are illustrated as being positioned in side-by-side arrangement on the deck of a vessel 11. It is to be understood that. in most cases when a pair of hose reels 18 and 1811 are employed for carrying multiple pressure hoses or electrical conduits, both reels 1 8 and 1811 would have substantially the same amount ofhose depending from them at the same time. [For ease of illustration, hose reel 18 is illustrated with allio f the hoses reeled off the drum" while hose reel 18a is shown with practically a drum full of hos-es. Hose reel 18 isshown as being provided with 7 seven flexible hoses 1-57. Although the hoses could be arranged on the drum 35 so that the couplings at the upper end thereof extend through the side plate 36 and be provided with a coupling portion 40,- it is preferred to anchorthe hoses to the drum in a manner such that the" suitable hose connector means 40. It is to be. understood that the hose connector 40 is only a portion of the hose coupling to which another hose with a mating coupling portion could be readily connected. Preferably, the couplings employed in this position are quick-disconnect couplings to facilitate the connecting or disconnecting of the pressure hoses 41-, 42 and 43. Although only three pressure hoses 41-43 are illustratedas coming into-the hose reel [18 it is to be understood that the number of pressure hoses employ-ed may be equal tothe number of flexible hoses 51-57 which are reeled on the drum The nipples 6167 and the connector bar '58 form one suitable means for normally securing the hoses 51-57 to the hose reel 1-8 in communication with the connector couplings positioned on the outside of the hose reel. In addition to the-nipples 61-67 curving from a direction normal to the axis of the drum 35 to" a direction parallel to the axis, the nipples are also preferably curved to lay along the surface of the drurn'35 and, if desired, may be recessed in the top surface of the drum. The connector bar or manifold-58 may be of any suitable form and as shown in FIGURE 7 comprises a bar member extending between the

side plates

36 and 36a of the hose reel and being provided with a series of flow passages 59 therethrough, The nipple-s, for example nipple 62, may be secured to the top of the barin any suitable manner, as

' ed portion 63 of thepassageway 59.

' Inorderthat the hoses on the hose reel stay in sideby-si de relationship whether on or off the reel, suitable clamps or spacer elements are provided. For example, in FIGURE 4, the flexible hoses 51a-57a on the hose reel 18a are shown as being proivded with spacer elemerits 70 whichmay be in'the form of a splitbar element covered with hard rubber and provi ed with holes therein for containing the hoses in side-by-side relationship. The spacer elements 79 are preferably covered with hard rubber so that they do not injure the hoses when the hoses are stored'on the reel. The spacer elemerits 70 may be attached as needed along the lengths of hoses. I

Since it is often necessary to drill wells in deep water where lengths of pressure hose-could not support their own weight, hose supporting equipment is provided in accordance with the present invention. One or more winches 7-1 and 72 may be secured to the vessel 11 for suspending, over theside of the vessel, one or

more support cables

73 and 74. The winches 71- and 72 are preferably in the form of constant-tension Winches adapted'to reel in or out a portion of the

cables

73 and 74 as the vessel 11 rises and falls with the motion of the sea. While the installation of FIGURE 4 is illustrated with two winches 7-1 and 72 being provided for supportingthehoses from two hose reels 1'8 and1 8a, it is to be understood that a single winch could be used for one or more. hose reels or thattwo winches could be used for one or more hose reels in any combination desired.

tion at one end with the hoses 51-57 through the bar 58 a while the other ends of the nipples 61 67 extend through The flexible pressure :hoses 5l 57 are shown as being supported vatr-spaced intervals" alongttheir lengths by means of hose, clamps 75 .and76 which may be of any suitable type. A preferred form of hose clamp is illustrated in FlGUR-E3 as being'of the split-bar type with theend of one bar portion 80 being welded to a supporting frame 79 while the otherv portion 8-1- of the clamp is hinged by means of pin 82 to the'first portion 80 of the clamp or'to thesuppo'rt frame 79. Suitable connector means, :such as a bolt 83 with ahandle 84, may beemployed to secure flthemovable ends of thehose clamp sections 80. and81 together. The holes 85 through the clamp 80 "and 81: are preferably slightly larger than the outside diameter of the pressure hose to be positioned therein so. that the hose will not be compressed by the clamp. However, the hole 85, in the clamp is smaller than the coupling 86 at the end of a hose 87 so that the hose in being suspended from the clamp 84PM is supported by its upper coupling 86. In the event that each section of hose was 50 feet long, the hose clamps 75, 75a, 76 and 76a are spaced together with their sup port bars 78 and 79 at intervals along

support cable

73 and 74 of slightly less than 50 feet so that there is no tension in the hoses and so that each section of hose supports its own weight by means of its upper coupling in contact with a hose clamp 843-81.

The hoses on

hose reels

18 and 18a are reeled in s multaneously While the

winches

71 and 72 reel in the supporting

cables

73 and 74. In order to facilitate handling of this operation the hose clamps 75, 75a, 76 and 7611 are preferably of a quick-disconnect type. At the same time it is necessary to quickly disconnect the supporting

frames

78 and 79 from the supporting

cables

73 and 74 so that the rest of the cables can be reeled in. Any suitable connector means 90, 91, 92 and 93 may be employed. One suitable form is shown in FIGURE 5 as comprising a hollow

housing having portions

94 and 95 which may be connected together by means of pins, one of which is shown at 96.

Holes

97 and 98 are formed in the top and bottom of the

housing clamp sections

94 and 95 and are of a size slightly larger than the supporting cables 73. In addition, the recess 99 formed with the

clamp housing portions

94 and 95 is large enough to accommodate a button or stop member fixedly secured to the support cable (FIGURE 6), the button 100 being larger than the

holes

97 and 98 in the clamp housing so that it does not slip through. Thus, as the hoses from the

hose reels

18 and 18a are reeled in, at least one of the pins 96 would be taken out of the hinges of the

clamp housing sections

95 and 94 so that the clamp housings 90 and 91 could be open and pulled away from the supporting

cables

73 and 74 after the

hose clamp

75 and 75a had been disconnected from the hoses normally contained therein.
