Apparatus and method for handling umbilical or control lines for tubing of a well
A sliding spider (10) for supporting tubing (T) through a rig floor includes a fixed gate (60) and a movable body (30). The fixed gate (60) is fixedly positioned on a base assembly (20) and is positioned adjacent one side of the tubing (T). The fixed gate (60) has a pair of locking ribs (66) for engaging the movable body (30) and has a roller (68) mounted atop the gate (60) for guiding a line (L) past the gate (60). The movable body (30) is positioned on the base assembly (20) adjacent another side of the tubing (T). The movable body (30) defines an open throat (32) for the tubing (T) and has first and second body portions (41a-b) connected together by a hinge pin (44). The movable body (30) slides on the base assembly (20) to an advanced position over an opening (24) in the base assembly (20) such that the tubing (T) is positioned through the open throat (32) of the body (30). When in the advanced position, a pair of ribs (46) on movable body (30) engages the pair of ribs (66) on the fixed gate (60) to lock the body portions (41a-b) around the tubing (T). Slips (54) are moved within the open throat (34) to engage the tubing (T) so that sections of tubing can be added or removed during well operations. An arm assembly (70) is pivotably attached to the fixed gate (60) for guiding one or more lines (L) and moving them nest to the tubing (T) for clamping.
The subject matter of the present disclosure generally relates to a spider for supporting a tubing string of a well and more particularly relates to a spider for supporting tubing of a well being slideable relative to a fixed gate, having an arm assembly for handling umbilical or control lines.
BACKGROUND OF THE INVENTIONSliding spiders are known in the art. One example of a sliding spider is the 350-ton Deepwater Sliding Spider by Bilco Tools, Inc. The sliding spider is used to support a tubing string of a well when sections of tubing are added or removed. For example, the spider is rigged up on a drilling rig by a series of steps beginning with placing the spider's base plate over the rotary table. The base plate contains a hole through which the tubing passes. The sliding assembly is placed on top of the base plate such that the slip assembly may slide over or away from the hole in the base plate as desired by the operator. Tubing is run through the hole in the base plate and the rotary table. When a section of tubing is to be added to a tubing string, the sliding spider is slid toward the tubing. A gate on the spider is left open so that the tubing fits within an open throat of the spider. An operator then closes the pivoting gate and locks the free end of the gate with a pin. Typically, sliding spiders are particularly useful when an umbilical or one or more control lines are run along the tubing to carry electrical or optical wiring or hydraulics to downhole equipment or sensors. Closing the gate on the sliding spider may be difficult when a large umbilical (e.g., an umbilical with a 4-inch diameter) is run adjacent the tubing. For example, operators may have to force the umbilical next to the tubing in order to close the gate.
After closing the gate, the operator lowers slips into a bowl of the spider, which engage the tubing. While the spider holds the tubing, a section of tubing is added to the end of the string using tongs and other devices. After the section has been added, an elevator holds the tubing string, and the slips on the spider are disengaged from the tubing. The string is then lowered through the opening in the rig floor. As the tubing is lowered, the umbilical or control lines are clamped to the tubing using protector clamps Because the sliding spider typically will not allow the clamps to pass through the open throat of the spider after applying the clamp, the spider is withdrawn, and the tubing and clamp can be lowered through the opening in the rig floor. When the elevator reaches a location near the sliding spider, the sliding spider is again engaged with the tubing to hold the tubing string so that the process can be repeated and a new section of tubing can be added.
Clamping an umbilical or control line to the tubing can require considerable effort by operators. For example, operators have to push an umbilical against the tubing and apply the protector clamp around the tubing and umbilical. When the umbilical has a large diameter (e.g., 4-inch diameter), pushing and holding the umbilical next to the tubing for attaching the clamp may be difficult. In other examples, more than one line may be used with the tubing. Operators must arrange the lines to match the spacing or arrangement on a protector clamp intended to clamp the lines to the tubing and then hold the multiple lines while they are clamped to the tubing. In addition, the operators must feed the multiple control lines down the hole as the tubing is lowered to prevent entangling the lines. For these reasons, clamping umbilical or control lines to the tubing can use valuable rig time to complete. Reducing the time required to clamp the lines to the tubing at each joint can create a significant reduction in running time and cost.
The subject matter of the present disclosure is directed to overcoming, or at least reducing the effects of, one or more of the problems set forth above.

BRIEF DESCRIPTION OF THE DRAWINGSThe foregoing summary, preferred embodiments, and other aspects of subject matter of the present disclosure will be best understood with reference to a detailed description of specific embodiments, which follows, when read in conjunction with the accompanying drawings, in which:
While the disclosed sliding spider is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. The figures and written description are not intended to limit the scope of the inventive concepts in any manner. Rather, the figures and written description are provided to illustrate the inventive concepts to a person skilled in the art by reference to particular embodiments, as required by 35 U.S.C. § 112.
DETAILED DESCRIPTIONA. Overview of the Sliding Spider
Referring to
In a preferred embodiment, the sliding spider 10 includes an arm assembly 70. The arm assembly 70 is pivotably attached to the gate assembly 60 by a pivotable connection 73, and an actuator 87 preferably moves or pivots the arm assembly 70 relative to the tubing T. The arm assembly 70 has a roller or guide assembly 74 for guiding umbilical or control lines L for the tubing T, as disclosed below.
The several components of the sliding spider 10 are preferably modular, allowing the spider 10 to be conveniently assembled/disassembled on a rig. For example, the base assembly 20 is a separate component that can be pre-slung and moved into position on the rig floor by a crane when assembling the spider 10. Likewise, the sliding assembly 30 is also a separate component that can be pre-slung and moved into position onto the base assembly 20. The fixed gate assembly 60 is also a separate component and attaches to the sliding assembly 30, as described below. Finally, the arm assembly 70 is a separate component that attaches to the gate assembly 60. It is believed that having the various modular components of the sliding spider 10 as discussed above may require only about one hour of assembly time to rig up.
B. Overview of the Operation of the Arm Assembly
During well operations, the tubing T as well as one or more lines L are raised or lowered through openings (not shown) in the base 20 and rig floor. As used herein and in the appended claims, “tubing” refers to production tubing, risers, or other tubulars used in well operations. As used herein and in the appended claims, “line” refers to a control line, an umbilical, a flat pack, smaller tubing, or other device used for carrying electronic or optical wiring, fluids, or hydraulics to downhole equipment and sensors. As is known, an umbilical is typically a bundle of several, smaller control lines and can be about 4-inches in diameter, for example. As is also known, a flat pack is typically a collection of several lines aligned together in a flat arrangement.
In
At certain points along the tubing T, the one or more lines L are clamped to the tubing T with a clamp (not shown). To attach the clamp, the one or more lines L are moved adjacent the tubing T with the arm assembly 70. If the one or more lines L are not already aligned on the roller assembly 74, an operator may simply gather the lines L and arrange them on roller assembly 74. For those instances where the lines pass on the roller assembly 74, the lines L may already have their preferred arrangement for clamping to the tubing. The actuator 87 pivots the arm assembly 70 about its hinged connection 73 with the gate assembly 60, and the one or more lines L are, therefore, brought adjacent or substantially parallel to the tubing T, as shown in
With the lines L held adjacent the tubing T with the arm assembly 70, operators can then place the clamp C shown in
As a further benefit, when the sliding assembly 30 is retracted, one or more hole covers can be positioned in a suitable rectangular area over the opening 24 in the base plate 26. The rectangular area is best visible from the side as area 29 in
C. Overview of the Operation of the Sliding Assembly
At certain points during well operations, the tubing string T handing through the opening in the rig floor must be supported while sections of tubing above the rig floor are added or removed using tongs and other well equipment. To support the tubing T, the sliding assembly 30 is moved to an advanced position to engage the tubing T and the fixed gate assembly 60. As best shown in
To support the tubing T, the slip assembly 50 is held in an elevated position, and the sliding assembly 30 is advanced towards the fixed gate assembly 60.
Once the sliding assembly 30 is engaged with the fixed gate assembly 60, the slip plate 50 is lowered by the actuators 85, and the slips 54 are positioned within the slip well 34 of the throat 32, as best shown in
Given the foregoing overview of the sliding spider 10, more detail descriptions of each of the assemblies 20, 30, 40, 50, 60, and 70 of the sliding spider 10 are discussed below.

E. Base Assembly
Referring to
The base 22 and base platform 26 each define an opening 24 for passage of the tubing T. In one embodiment, the openings 24 can have a diameter of about 21-inches, which may accommodate most anchor assemblies and subsea test trees used on deepwater rigs. Preferably, the openings 24 are designed to permit passage of a tubing hanger assembly and running tools currently available. The diameter of the opening 24 in a preferred embodiment is approximately 21-inches because the largest assembly/tool structures currently in use have a diameter of about 19.50-inches. The openings 24 also have slots 23 that extend to the edges of the base 22 and base platform 26. The slots 23 accommodate the line L and also allow the base 22 and base platform 26 to be positioned on the rig floor when tubing T is present.
The sliding platform 36 of the sliding assembly has an opening 38 that is generally complementary to, but smaller than, the openings 24 of the base 22 and platform 26. The sliding platform 36 also has a slot 39 that is complementary to the slots 23 of the base 22 and base platform 26. As best shown in

When the lift actuators 85 are operated, the slip plate 52 can be raised or lowered to move the slips 54 out of and into the slip well 34 formed in the sliding assembly 30. As best shown in
H. Arm Assembly
In the disclosed embodiments, such as shown in
Referring to
As best shown in
As best shown in
In the present embodiment, the roller 75 rotates about a pin, which passes through the side turrets 76. Ends of the side turrets 76 are pivotably attach to one of the parallel arms 72 by the hinge connections 77. The adjustment knob 78 has a screw passing through a threaded opening in a plate connecting the turrets 76. The knob 78 can be rotated to change the pivot position of the roller 75. Adjusting the knob 78 allows an operator to adjust the position of the roller 75 to accommodate various diameters of lines when the arm assembly 70 is pivoted adjacent the tubing.
In the present embodiment, the arm assembly 70 uses the roller 75 to guide a line and reduce friction as the line passes the end of the arm assembly 70. Alternative embodiments of the roller assembly 70 can include devices other than a roller for guiding a line and/or reducing friction of the line past the end of the arm assembly 70. In one alternative embodiment, for example, a guide mounted on the distal end of the arm assembly 70 can be used instead of a roller. The guide can be generally concave or U-shaped and can have a friction-reducing surface, which can be composed of a brush material or the like. The cup or U-shape of the guide can substantially hold the line on the distal end of the arm assembly 70, and the friction-reducing surface can be used to reduce friction of the line as it is passed over the guide.
I. Alternative Roller Assemblies
Because more than one line may be used with tubing in a well operation, embodiments of the roller assembly 70 on the distal end of the pivotable arm assembly 70 are preferably capable of handling multiple lines. Moreover, the roller 68 on the fixed gate 60 can also be capable of handling multiple lines. Referring to
Rollers disclosed herein can be composed of a suitable material, such as metal, Teflon, or UHMW. Furthermore, bearings, spacers, and the like can be used to reduce friction of the rollers. In addition, the embodiments of the roller systems and rollers disclosed below can be used with the arm assembly 70 and/or the fixed gate 60 disclosed herein.
1. Embodiment of Roller with Multiple Slots
Referring to
The roller 100 includes a plurality of slots or guides 111, 112, and 113 formed circumferentially in the roller 100. The lines L1, L2, and L3 fit separately into the slots 111-113. In the present embodiment, three slots 111-113 are shown, but other embodiments of the disclosed roller 100 can have more or less slots depending on the number of lines to be used with the tubing. Moreover, the sizes, depths, and spacing of the slots can differ depending of the particular lines to be used and the arrangement of the protector clamp intended to clamp the lines to the tubing. As is known in the art, protector clamps are used to clamp the lines to the tubing at regular intervals, such as at every joint. Therefore, the positioning of the slots 111-113 in the roller 100 can be designed to best position or arrange the lines for the intended clamp. The present embodiment of roller 100, as well as the other embodiments of roller assemblies and rollers disclosed herein, enables operators to arrange and guide the lines according to the arrangement the lines are intended to be clamped to the tubing, which can save valuable rig time.
For example, the body T may represent the tubing of a well operation. Therefore, the concave contour of the roller 100 can be formed to the contour of the tubing, and the roller 100 can be designed with the number, sizes, depths, and spacing of the slots 111-113 that best suits the intended arrangement for clamping of the lines to the tubing body T. In another example, the body T may represent a “large” umbilical line, which can be 4-inches in diameter, for example, and the lines L1-L3 can be smaller control lines. Therefore, the concave contour of the roller 100 can be formed to the contour of the umbilical line B, and the roller 100 can be designed with the number, sizes, depths, and spacing of the slots 111-113 that best suits the intended arrangement for clamping of the lines L1-L3 to the umbilical line B and tubing.
