[0001] Tubing hangers for subsea trees are deployed inside a marine riser and require hydraulic and/or electrical controls. In some cases, a subsea test tree or subsea safe tree is utilized above a tubing hanger running tool and also requires hydraulic and/or electrical controls.

Deploying the umbilical and clamping it to the drill pipe while the rig is deploying a subsea device such as a tubing hanger and/or subsea test tree is time consuming due to the speed of the reel, clamping efforts, and mitigating the risks of damaging the controls umbilical.

DESCRIPTION OF EXEMPLARY EMBODIMENTS
[0012] Referring generally to Fig. 1, riser tree controls adapter 1 generally comprises outer riser tree controls adapter 10 and inner riser tree controls adapter 60. Fig. 11 illustrates a general subsea installation including marine riser 100, tubular 101, marine riser joints 102, lower marine riser package 104, subsea test tree 105, blowout preventer ("BOP") 106, tubing hanger running tool 110, tubing hanger 112, and subsea tree 114.
[0013] Referring additionally to Fig. 2, outer riser tree controls adapter 10 typically comprises outer riser tree controls adapter housing 13, which is typically substantially tubular and which defines inner outer riser tree controls adapter housing annulus 16; orientation port 14 extending from an outer surface of outer riser tree controls adapter housing 13 into inner outer riser tree controls adapter housing annulus 16; orientation pin 20 configured to be slidingly received into orientation port 14 and to extend a predetermined length into inner outer riser tree
controls adapter housing annulus 16; one or more inner connection interfaces 12 disposed at predetermined locations within inner outer riser tree controls adapter housing annulus 16, each typically having a predetermined portion accessible from inner outer riser tree controls adapter housing annulus 16; and control umbilical junction plate 30 attached to the outer surface of substantially tubular outer riser tree controls adapter housing 13, typically opposite orientation port 14 but at a location that does not need to be opposite orientation port 14.
[0014] Orientation pin 20 may further comprise mechanical drive 80, e.g. a torque tool, attached to a distal end of orientation pin 20, where mechanical drive 80 is adapted to be maneuvered by a remotely operated vehicle ("ROV") when orientation pin 20 is inserted into or retrieved out from orientation port 14. Generally, mechanical drive 80 is not activated until equipment such as subsea test tree 105 (Fig. 1) has passed through outer riser tree controls adapter housing 13. Further, mechanical drive 80 typically inserts orientation pin 20 into outer riser tree controls adapter housing 13 to help properly align inner riser tree controls adapter 60. By way of example and not limitation, when activated orientation pin 20 can catch or otherwise engage inner riser tree controls adapter 60 and cause inner riser tree controls adapter 60 to rotate about tubular 101 (Fig. 1).
[0015] Control umbilical junction plate 30 typically further comprises junction plate housing 40, configured to removably receive controls umbilical 50, and junction plate control connection receiver 31, adapted to receive one or more controls umbilical connections 52 and provide a set of control signal pathways 15 between junction plate control connection receiver 31 and a corresponding set of inner connection interfaces 12.
[0016] Inner outer riser tree controls adapter housing annulus 16 is typically further configured to accept a piece of equipment therethrough, such as subsea test tree 105 (Fig. 1),
tubing hanger running tool 110 (Fig. 11), or the like. Conduit 74 (Fig. 4) is in communication with the piece of equipment.
[0017] In embodiments, outer riser tree controls adapter 10 further comprises shelf 17 disposed at a predetermined position within inner outer riser tree controls adapter housing annulus 16, where shelf 17 is configured to accept inner connection interfaces 12 therethrough.
[0018] Referring additionally to Figs. 3 and 4, inner riser tree controls adapter 60 typically comprises substantially tubular inner riser tree controls adapter housing 62 which, as illustrated in Fig. 3, may comprise a plurality of inner riser tree controls adapter housing portions such as 62a,62b. Substantially tubular inner riser tree controls adapter housing 62 is configured to be received into inner outer riser tree controls adapter housing annulus 16 and defines substantially tubular inner riser tree controls adapter inner annulus 69 configured to receive equipment such as tubular 101 (Fig. 1) therethrough.
[0019] Inner riser tree controls adapter 60 further comprises orientation pin guide 71 disposed about an outer surface of the substantially tubular inner riser tree controls adapter housing 62 and configured to slidingly receive orientation pin 20 (Fig. 2). Substantially tubular inner riser tree controls adapter housing 62 typically further comprises initial engagement section 73 comprising tapered insertion end 75 which is tapered at an angle, and configured to slidingly receive orientation pin 20 and guide orientation pin 20 into the orientation pin guide 71.
[0020] One or more adapter control connectors 68 are also present and configured to operatively mate with a corresponding set of inner connection interfaces 12 (Fig. 2) and provide communication between controls umbilical connections 52 (Fig. 1) and one or more conduits 74 (Fig. 4).
[0021] If shelf 17 (Fig. 2) is present, substantially tubular inner riser tree controls adapter housing 62 may further comprise shelf 63 configured to selectively engage shelf 17 and support adapter control connector 68.
[0022] As noted above, inner riser tree controls adapter 60 may comprise a plurality of inner riser tree controls adapter housings, e.g. housings 62a,62b, which are configured to cooperatively and securely engage each other and clamp to tubular 101 (Fig. 1) , e.g. a drill pipe, at a predetermined location about tubular 101. In certain embodiments, the plurality of inner riser tree controls adapter housings 62a,62b are configured to be bolted together such as with bolts 660.
[0023] In most configurations, orientation pin 20 (Fig. 2) is configured to slidingly engage inner riser tree controls adapter 60 at and/or within orientation pin guide 71, and typically configured to force inner riser tree controls adapter 60 to rotate about tubular 101 (Fig. 1) and properly align adapter control connector 68 and inner connection interface 12 (Fig. 2). Inner riser tree controls adapter 60 is typically configured to be able to rotate about tubular 101 without requiring tubular 101 to rotate.
[0024] In order to better control riser tree controls adapter 1 (Fig. 1), orientation pin guide 71 may comprise orientation pin travel limiter 402 which will stop or otherwise limit travel of orientation pin 20 within orientation pin guide 71. In embodiments, orientation pin guide 71 comprises initial engagement section 73 which is wider than orientation pin travel limiter 402 and progressively narrows from initial engagement section 73 to orientation pin travel limiter 402. In most operations adapter control connectors 68 should bottom out first.
[0025] Referring now to Figs. 5-10, clamp 70 (Fig. 8) may be present and disposed about a predetermined portion of tubular 101 (Fig. 8). Additionally, spring 72 (Fig. 8) may disposed
intermediate clamp 70 and inner riser tree controls adapter 60 at a predetermined location. Spring 72, if present, is typically configured to allow for a predetermined amount of vertical movement of inner riser tree controls adapter 60 with respect to a longitudinal axis of tubular 101, by way of example and not limitation allowing for between around one 1 foot to around ten 10 feet of vertical movement.
[0026] Referring back to Figs. 2 and 4, in certain embodiments first protective covering
400 (Fig. 2) is disposed about inner connection interface 12 and second protective covering 401 (Fig. 4) is disposed about adapter control connector 68, each protective covering 400,401 being configured to prevent damage when the inner riser tree controls adapter 60 is not in use.
[0027] In the operation of exemplary embodiments, referring generally to Fig. 1 and
Figs. 5-8, inside riser tree controls adapter 1 may be used to move connections from inside riser 102 (Fig. 1) to outside riser 102. Doing so may reduce the risk of a controls umbilical such as controls umbilical 50 being damaged, reduce rig down time, and increase rig efficiency by increasing the speed of deployment and retrieval.
[0028] Inner riser tree controls adapter 1 may be provided by deploying outer riser tree controls adapter 10 about a first predetermined portion of an outer surface of tubular 101. Outer riser tree controls adapter 10 is as described above.
[0029] In certain embodiments where housing 62 comprises a plurality of housing portions such as 62a,62b (Fig. 3), deploying inner riser tree controls adapter 60 about tubular 101 comprises positioning and placing each such portion about tubular 101 and then securing each such portion to each other portion, e.g. by clamping and/or bolting the portions together using one or more bolts 660. One or more bolt plates 64,65,66,67 may be provided to accommodate bolting or otherwise securing housing portions as 62a,62b together.
[0030] Inner riser tree controls adapter 60 is deployed about a second predetermined portion of tubular 101, where inner riser tree controls adapter 60 is as described herein, and maneuvered to where orientation pin guide 71 is proximate to orientation pin 20. Orientation pin 20 is then engaged via orientation port 14 into orientation pin guide 71 and inner riser tree controls adapter 60 mated into inner outer riser tree controls adapter housing annulus 16 until adapter control connector 68 operatively mates with inner connection interface 12.
[0031] In certain embodiments, operatively mating adapter control connector 68 with inner connection interface 12 further comprises providing inner connection interface 12 with first protective covering 400 (Fig. 2) and adapter control connector 68 with second protective covering 401 (Fig. 4) used to help prevent damage when inner connection interface 12 and/or not adapter control connector 68 are not in use.. These protective coverings 400,401 may be removed once inner riser tree controls adapter 60 is properly aligned and, thereafter, adapter control connector 68 is interfaced with inner connection interface 12.
[0032] Typically, orientation pin 20 is allowed to guide travel of inner riser tree controls adapter 60 into inner outer riser tree controls adapter housing annulus 16 during the mating of inner riser tree controls adapter 60 into inner outer riser tree controls adapter housing annulus 16. If orientation pin travel limiter 402 is present, travel of inner riser tree controls adapter 60 into inner outer riser tree controls adapter housing annulus 16 to where adapter control connector 68 operatively mates with inner connection interface 12 further comprises using orientation pin travel limiter 402 to limit the procession of inner riser tree controls adapter 60 into inner outer riser tree controls adapter housing annulus 16 by if travel beyond orientation pin travel limiter 402 is attempted. However, as noted above, in most operations adapter control connectors 68 should bottom out first.
[0033] In these and other embodiments, travel of inner riser tree controls adapter 60 into inner outer riser tree controls adapter housing annulus 16 to where adapter control connector 68 operatively mates with inner connection interface 12 may comprise, or may additionally comprise, limiting travel of inner riser tree controls adapter 60 into inner outer riser tree controls adapter housing annulus 16 by providing outer riser tree controls adapter 10 with shelf 17 disposed at a predetermined position within inner outer riser tree controls adapter housing annulus 16, where shelf 17 is configured to accept inner connection interface 12 therethrough, and providing inner riser tree controls adapter housing 62 with shelf 63 configured to selectively engage shelf 17. Travel of inner riser tree controls adapter 60 into inner outer riser tree controls adapter housing annulus 16 is then substantially stopped when shelf 63 engages shelf 17. If inner riser tree controls adapter housing 62 comprises a plurality of housing portions, e.g. 62a,62b, one or more of the housing portions may comprise one or more shelves 63.
[0034] In various embodiments, inner riser tree controls adapter housing 62, whether a single housing 62 or multiple housing pieces such as 62a,62b, comprises initial engagement section 73 which is tapered at an angle to tapered insertion end 75. Tapered insertion end 75 is configured to slidingly receive orientation pin 20 and guide orientation pin 20 into orientation pin guide 71.
[0035] In embodiments with a progressively narrowing orientation pin guide 71 such as but not limited to that which is illustrated in Fig. 3, orientation pin 20 is allowed to engage with initial engagement section 73 and inner riser tree controls adapter 60 allowed to rotate about tubular 101 as inner riser tree controls adapter 60 progresses into inner outer riser tree controls adapter housing annulus 16 without requiring tubular 101 to rotate.
[0036] Travel of inner riser tree controls adapter 60 is allowed to progress into inner outer riser tree controls adapter housing annulus 16 to where adapter control connector 68 operatively mates with inner connection interface 12, as described above.
[0037] Typically, controls umbilical 50 (Fig. 1) is received into control umbilical junction plate 30, which is as described above, after adapter control connector 68 operatively mates with inner connection interface 12, but need not be, e.g. connecting controls umbilical 50 to junction plate housing 40 may occur prior to or after deployment of tubing hanger 112 (Fig. 11) and/or subsea test tree 105 (Fig. 1).
[0038] Once received into control umbilical junction plate 30, controls umbilical 50 is typically secured into control umbilical junction plate 30 and junction plate control connection receiver 31 mated with controls umbilical connection 52, providing one or more control signal pathways 15 between each junction plate control connection receiver 31 and each corresponding inner connection interface 12.
[0039] If clamp 70 is used, it is typically disposed about a predetermined portion of tubular 101 above inner riser tree controls adapter 60, e.g. towards the sea surface. Typically, spring 72 is also used if clamp 70 is used, where spring 72 is disposed intermediate clamp 70 and inner riser tree controls adapter 60 at a predetermined location. As described above, spring 72 is typically configured to allow for a predetermined amount of vertical movement of inner riser tree controls adapter 60 with respect to a longitudinal axis of tubular 101, by way of example and not limitation allowing for between around one 1 foot to around ten 10 feet of vertical movement [0040] The foregoing disclosure and description of the inventions are illustrative and explanatory. Various changes in the size, shape, and materials, as well as in the details of the
illustrative construction and/or an illustrative method may be made without departing from the spirit of the invention.
