Cross-Reference to Related Applications

[0001] This application claims priority to U.S. Provisional Patent Application No. 62/591,260, filed on November 28, 2017, which is hereby incorporated by reference in its entirety.

Background

[0002] Drilling operations may be conducted on a drilling rig that includes a drilling platform located above a drilling location. A blow-out preventer (BOP) may be positioned underneath the drilling platform on a wellhead. A BOP is a large valve at the top of a wellbore that may be closed if the drilling crew loses control of formation fluids. By closing this valve, the drilling crew may regain control of the reservoir. When more than one BOP is used, this may be referred to as a BOP stack. A BOP stack may include one or more annular BOPs and/or one or more ram BOPs.

[0003] An annular BOP may be or include a valve used to control wellbore fluids. In this type of valve, the sealing element resembles a large rubber doughnut that is mechanically squeezed inward to seal on either pipe (e.g., drill collar, drill pipe, casing, or tubing) or the open hole. A ram BOP is a type of BOP in which the pressure-control functions are achieved through the operation of hydraulically-operated ram sets. Each ram set is configured as an opposing pair that is designed to close within the bore of the preventer. In one example, a BOP stack may include an annular BOP, a single-ram BOP, and a double-ram BOP.

[0004] Various methods of transporting and handling BOP components (e.g., annular BOPs and/or ram BOPs) are currently utilized. For example, the BOP components may be transported in modules and assembled and pressure-tested under the drill floor. BOP components are of varying shapes and weights and involve precise alignment to assemble. In addition, access for maintenance operations is often difficult to achieve, and“jury-rigging” is often the solution for performing these maintenance operations. As such, assembly and maintenance of BOP components may present safety risks and potentially involve down-time for the drilling rig. Summary

[0023] Attention is now directed to processing procedures, methods, techniques, and workflows that are in accordance with some embodiments. Some operations in the processing procedures, methods, techniques, and workflows disclosed herein may be combined and/or the order of some operations may be changed. [0024] Figure 1 illustrates a front view of a blow-out preventer (BOP) handling apparatus 100, according to an embodiment. The BOP handling apparatus 100 may include a movement guide system, such as the illustrated rail system 102, as well as a hoist structure 104. The hoist structure 104 may be positioned on the rail system 102. The BOP handling apparatus 100 may also include a drive system 106. The drive system 106 may be configured to move the hoist structure 104 along the rail system 102 into and/or out of alignment with a wellbore and/or wellhead (i.e., well center). The drive system 106 may include one or more wheels that are configured to travel (i.e., roll) along the rail system 102. In another embodiment, the drive system 106 may include one or more cylinders that are configured to expand and retract to move the hoist structure 104. The drive system 106 may be powered electrically, pneumatically, and/or hydraulically.

[0025] The BOP handling apparatus 100 may also include a BOP hoist device 108 that is coupled to the hoist structure 104. For example, the hoist device 108 may be suspended (e.g., over well center) by the hoist structure 104. The hoist device 108 may be configured to hoist (i.e., raise) and/or lower one or more components coupled thereto using one or more cables 109. In at least one embodiment, the one or more components may make up a BOP stack. The hoist device 108 may be powered electrically, pneumatically, and/or hydraulically. In at least one embodiment, the hoist device 108 may include a rotation device (e.g., a turntable) 110 that is configured to rotate the one or more components that are coupled to the hoist device 108 before, during, or after assembly.

[0026] The BOP handling apparatus 100 may also include one or more maintenance assistance hoists 111. The BOP handling apparatus 100 may also include a BOP lift ring 112 (shown in Figures 6 and 8-10) configured to couple to the one or more components that make up the BOP stack. As discussed in greater detail below, the lift ring 112 may be configured to be raised and lowered by the hoist device 108 and the cables 109 and to support the weight of the BOP stack. The BOP handling apparatus 100 may also include a jib boom 114 configured to handle (e.g., move and/or lift) the BOP lift ring 112 and/or to provide assistance during maintenance tasks. In one example, the maintenance assistance hoists 111 and/or the jib booms 114 may be configured to handle replacement rams and may be configured to assist in other tasks such as positioning BOP lift ring 112 or connecting choke and kill hoses. One or more hoists 116 on the jib boom 114 may be electric, pneumatic, and/or hydraulic. [0027] The BOP handling apparatus 100 may also include one or more bales 118 (see Figure 7). The bales 118 may be configured to couple to the one or more components that make up the BOP stack. As discussed in greater detail below, the bales 118 may be configured to be raised and lowered by the hoist device 108 and the cables 109 and to support the weight of the BOP stack. For example, the bales 118 may be configured to help raise and/or lower the one or more components that make up the BOP stack. The bales 118 may be coupled to a bolt pattern of a first (e.g., upper) ram BOP. The bales 118 may be used instead of, the BOP lift ring 112.

[0028] The BOP handling apparatus 100 may also include one or more maintenance walkways 120 configured to provide access for a user to multiple locations on the BOP handling apparatus 100 (e.g., for assembly and/or repair). The positioning (e.g., height) of the walkways 120 may be adjustable. The BOP handling apparatus 100 may also include a test stump 122 (see Figures 8-10) including a pump and a test recorder. The test stump 122 may be configured to test one or more components of the BOP stack before, during, or after assembly. For example, the test stump 122 may be configured to perform off-line pressure testing of one or more components that make up the BOP stack (before assembly), or the full BOP stack after it is assembled. Thus, the test stump 122 may be or include a pump, a pressure sensor, and a recorder.

[0029] The BOP handling apparatus 100 may also include one or more transport skids (also called a transport frame) 124 (see Figure 2) configured to move the one or more components that make up the BOP stack into alignment with (and under) the hoist device 108, as described below. The BOP handling apparatus 100 may also include a control system 126 configured to control operation of the hoist device 108 and/or the rotation device 110. The BOP handling apparatus 100 may also include a secondary BOP retention system 128 (see Figures 6 and 8-10). The secondary BOP retention system 128 may include attachment devices, link plates, slings, or the like. In at least one embodiment, the secondary BOP retention system 128 may work in conjunction with (e.g., be coupled to) the bales 118. The secondary BOP retention system 128 may be configured to support a total weight of the BOP stack when moving on and off well center or suspending the BOP stack while performing various functions. The secondary BOP retention system 128 improves operational safety by providing a secondary means to support the BOP stack in the case of hoist failure. [0030] Figure 2 illustrates a top (plan) view of the BOP handling apparatus 100, according to an embodiment. The BOP handling apparatus 100 may be positioned between two sub base boxes 202, 204. The rail system 102 may be coupled to and/or positioned on the sub base boxes 202, 204 or the ground to enable the BOP handling apparatus 100 to be moved (e.g., by the drive system 106) into alignment with the well center 206. As described below, the transport skid 124 may move/transport one or more components that make up the BOP stack into alignment with the BOP handling apparatus 100 and/or well center 206.

[0031] Figures 3A-3C illustrate a flowchart of a method 300 for assembling the BOP stack, according to an embodiment.

Incorporating the annular BOP 140 may include moving the transport skid 124 and/or the annular BOP 140 into alignment with the hoist device 108 and/or well center 206, as at 306. This is shown in Figure 1. Incorporating the annular BOP 140 may also include coupling the hoist device 108 to the annular BOP 140, as at 310. This may include, for example, lowering the cable(s) 109 from the hoist device 108, and coupling the cables 109 to coupling members (e.g., pad eyes 141) of the annular BOP 140. Incorporating the annular BOP 140 may also include lifting the annular BOP 140 off of the transport skid 124 using hoist device 108, as at 312. This is shown in Figure 4. Incorporating the annular BOP 140 may also include moving the transport skid 124 out from under the hoist device 108 and the annular BOP 140, as at 314.

[0032] The method 300 may also include incorporating a second component (e.g., a first ram BOP 142) into the BOP stack, as at 316. The first (e.g., upper) ram BOP 142 may be or include a single-ram-type BOP or a double-ram-type BOP (as shown). Incorporating the first ram BOP 142 may include moving the transport skid 124 and/or the first ram BOP 142 into alignment with (and under) the hoist device 108 and/or the annular BOP 140, as at 320. This is shown in Figure 5. Incorporating the first ram BOP 142 may also include lowering the annular BOP 140 onto the first ram BOP 142 using the hoist device 108, as at 322. Incorporating the first ram BOP 142 may also include coupling the annular BOP 140 to the first ram BOP 142, as at 324.

[0033] The pad eyes 141 on the annular BOP 140 may be rated or otherwise configured to support the weight of the annular BOP 140, but may not be rated or otherwise configured to support additional weight (e.g., the weight of the first ram BOP 142). Accordingly, in at least one embodiment, incorporating the first ram BOP 142 may also include coupling (e.g., using bolts) the BOP lift ring 112 to the annular BOP 140 and/or the first ram BOP 142, as at 326. The BOP lift ring 112 is rated to support (e.g., raise and/or lower) the weight of the annular BOP 140, the first ram BOP 142, and one or more other components that make up the BOP stack.

[0034] Incorporating the first ram BOP 142 may also include de-coupling the cables 109 of the hoist device 108 from the (e.g., pad eyes 141 of the) annular BOP 140, and coupling the cables 109 of the hoist device 108 to the BOP lift ring 112, as at 327. Incorporating the first ram BOP 142 may also include lifting the first ram BOP 142 off of the transport skid 124 using the hoist device 108 and the BOP lift ring 112, as at 328. This is shown in Figure 6. Incorporating the first ram BOP 142 may also include moving the transport skid 124 out from under the BOP lift ring 112, the annular BOP 140, and/or the first ram BOP 142, as at 330.

[0035] Figure 7 shows an alternative embodiment to Figure 6 where the bales 118 are coupled to the annular BOP 140 and/or the first ram BOP 142. More particularly, the cables 109 may be coupled to the bales 118, and the first ram BOP 142 may be lifted off of the transport skid 124 using the hoist device 108 and the bales 118. The bales 118 may be used instead of the BOP lift ring 112.

[0036] The method 300 may also include incorporating a third component (e.g., a first drilling spool 144) into the BOP stack, as at 332. Incorporating the first (e.g., upper) drilling spool 144 may include moving the transport skid 124 and/or the first drilling spool 144 into alignment with (and under) the hoist device 108, the BOP lift ring 112, the annular BOP 140, and/or the first ram BOP 142, as at 336. This is shown in Figure 8. Incorporating the first drilling spool 144 may also include lowering the first ram BOP 142 onto the first drilling spool 144 using the hoist device 108 and the BOP lift ring 112 (or the bales 118), as at 338. Incorporating the first drilling spool 144 may also include coupling the first ram BOP 142 to the first drilling spool 144, as at 340. Incorporating the first drilling spool 144 may also include lifting the first drilling spool 144 off of the transport skid 124 using the hoist device 108 and the BOP lift ring 112 (or the bales 118), as at 342. This is shown in Figure 9. Incorporating the first drilling spool 144 may also include moving the transport skid 124 out from under the hoist device 108, the BOP lift ring 112, the annular BOP 140, the first ram BOP 142, and/or the first drilling spool 144, as at 344.

[0037] The method 300 may also include incorporating a fourth component (e.g., a second ram BOP 146) into the BOP stack, as at 346. The second (e.g., lower) ram BOP 146 may be or include a single-ram-type BOP or a double-ram-type BOP (as shown). Incorporating the second ram BOP 146 may include moving the transport skid 124 and/or the second ram BOP 146 into alignment with (and under) the hoist device 108, the BOP lift ring 112 (or bales 118), the annular BOP 140, the first ram BOP, and/or the first drilling spool 144, as at 350. This is also shown in Figure 9. Incorporating the second ram BOP 146 may also include lowering the first drilling spool 144 onto the second ram BOP 146 using the hoist device 108 and the BOP lift ring 112 (or the bales 118), as at 352.

This is also shown in Figure 10. Incorporating the second drilling spool 148 may also include lowering the second ram BOP 146 onto the second drilling spool 148 using the BOP lift ring 112 (or the bales 118), as at 366. Incorporating the second drilling spool 148 may also include coupling the second ram BOP 146 to the second drilling spool 148, as at 368. Incorporating the second drilling spool 148 may also include lifting the second drilling spool 148 off of the transport skid 124 using the hoist device 108 and the BOP lift ring 112 (or the bales 118), as at 370. Incorporating the second drilling spool 148 may also include moving the transport skid 124 out from under the BOP lift ring 112, the annular BOP 140, the first ram BOP 142, the first drilling spool 144, the second ram BOP 146, and the second drilling spool 148, as at 372.

[0039] The combination of the annular BOP 140, the first ram BOP 142, the first drilling spool 144, the second ram BOP 146, and/or the second drilling spool 148 may produce the BOP stack 150, as shown in Figure 10. As will be appreciated, one or more of the components (e.g., the annular BOP 140, the first ram BOP 142, the first drilling spool 144, the second ram BOP 146, and/or the second drilling spool 148) may be omitted from the BOP stack 150. In other embodiments, additional components (e.g., annular BOPs, ram BOPs, drilling spools, etc.) may be added to the BOP stack 150.

[0040] In at least one embodiment, the method 300 may also include rotating one or more components of the BOP stack 150 (e.g., before, during, and/or after assembly) using the rotation device 110, as at 374. This may facilitate connection of one or more lines (e.g., control lines, kill lines, choke lines, etc.) to the one or more components. The rotation device 110 may be positioned on a polymer slide pad or rollers and may be powered with a rack and pinion drive, a hydraulic cylinder arrangement, or another device providing torque.

[0041] The method 300 may also include testing the BOP stack 150, as at 376. This may include pressure testing one or more components of the BOP stack 150 (e.g., before, during, and/or after assembly) using the test stump 122. For example, the pump may be coupled to a flange on the one or more components that make up the BOP stack 150, and the pump may increase a pressure applied thereto. The pressure sensor may measure the pressure within the one or more components that make up the BOP stack 150 and determine if the one or more components are sealing properly or if a leak is present. The results may be stored in the recorder.

[0042] In at least one embodiment, the BOP stack 150 may be assembled at least partially by the BOP handling apparatus 100 at a position that is away from (i.e., not aligned with) well center 206. In this embodiment, once the BOP stack 150 is assembled, the drive system 106 may cause the BOP handling apparatus 100 and the BOP stack 150 to move along the rail system 102 into alignment with well center 206. In another embodiment, the BOP handling apparatus 100 may be aligned with well center 206 prior to and/or during the assembly of the BOP stack 150.

[0043] The BOP handling apparatus 100 may be configured to assemble BOP assemblies of various sizes and with various combinations of components. In addition, the BOP handling apparatus 100 may be configured to assemble and move multiple BOP assemblies sequentially or simultaneously.
