Abstract

An articulated fluid delivery unit (FDU) is disposed to deliver fluid remotely to, for example, a mating fluid connection housing assembly provided on a wellhead. A stinger assembly on the FDU includes a fluid connection adapter configured to deliver fluid to the fluid connection housing assembly. The stinger assembly further includes a slew drive having a fixed portion and rotating portion. Rotation of the rotating portion enables presentation of the fluid connection adapter and a separate nightcap interchangeably to the fluid connection housing assembly.

Claims (32)

1. A fluid delivery unit, comprising:

a stinger assembly, the stinger assembly including a fluid connection adapter, the stinger assembly configured to deliver fluid to a separate fluid connection housing assembly via the fluid connection adapter;

the stinger assembly further including a slew drive, the slew drive having a fixed portion and rotating portion thereof, wherein the fluid connection adapter is connected to the rotating portion of the slew drive such that rotation of the rotating portion enables corresponding rotation of the fluid connection adapter;

a nightcap bracket, the nightcap bracket also connected to the rotating portion of the slew drive such that rotation of the rotating portion of the slew drive also enables corresponding rotation the nightcap bracket;

a nightcap, wherein the nightcap is selectably connectable to the nightcap bracket;

wherein, when the nightcap is connected to the nightcap bracket, rotation of the rotating portion of the slew drive enables presentation of the fluid connection adapter and the nightcap interchangeably to the fluid connection housing assembly.

2. The fluid delivery unit of claim 1 , in which the nightcap is selectably connectable to the nightcap bracket via a nightcap engage/release mechanism.

3. The fluid delivery unit of claim 2 , in which the nightcap includes a nightcap engagement pin, wherein the nightcap engagement/release mechanism is disposed to selectably engage and release the nightcap engagement pin, wherein release of the nightcap engagement pin enables the nightcap bracket to disconnect from the nightcap.

4. The fluid delivery unit of claim 3 , in which displacement of the nightcap engagement/release mechanism over the nightcap engagement pin enables the nightcap bracket to connect to the nightcap.

5. The fluid delivery unit of claim 2 , in which actuation of the nightcap engage/release mechanism is remotely controlled.

6. The fluid delivery unit of claim 1 , in which the nightcap is longitudinally opposed to the fluid connection adapter when the nightcap is connected to the nightcap bracket.

7. The fluid delivery unit of claim 1 , in which rotation of the rotating portion of the slew drive is remotely controlled.

8. A fluid delivery unit, comprising:

a stinger assembly, the stinger assembly including a fluid connection adapter, the stinger assembly configured to deliver fluid to a separate fluid connection housing assembly via the fluid connection adapter;

the stinger assembly further including a remotely-controlled slew drive, the slew drive having a fixed portion and rotating portion thereof, wherein the fluid connection adapter is connected to the rotating portion of the slew drive such that rotation of the rotating portion enables corresponding rotation of the fluid connection adapter;

a nightcap bracket, the nightcap bracket also connected to the rotating portion of the slew drive such that rotation of the rotating portion of the slew drive also enables corresponding rotation the nightcap bracket;

a nightcap, wherein the nightcap is selectably connectable to the nightcap bracket;

wherein, when the nightcap is connected to the nightcap bracket, rotation of the rotating portion of the slew drive enables presentation of the fluid connection adapter and the nightcap interchangeably to the fluid connection housing assembly.

9. The fluid delivery unit of claim 8 , in which the nightcap is selectably connectable to the nightcap bracket via a nightcap engage/release mechanism.

10. The fluid delivery unit of claim 9 , in which the nightcap includes a nightcap engagement pin, wherein the nightcap engagement/release mechanism is disposed to selectably engage and release the nightcap engagement pin, wherein release of the nightcap engagement pin enables the nightcap bracket to disconnect from the nightcap.

11. The fluid delivery unit of claim 10 , in which displacement of the nightcap engagement/release mechanism over the nightcap engagement pin enables the nightcap bracket to connect to the nightcap.

12. The fluid delivery unit of claim 9 , in which actuation of the nightcap engage/release mechanism is remotely controlled.

13. The fluid delivery unit of claim 8 , in which the nightcap is longitudinally opposed to the fluid connection adapter when the nightcap is connected to the nightcap bracket.

14. A fluid delivery unit, comprising:

a stinger assembly, the stinger assembly including a fluid connection adapter, the stinger assembly configured to deliver fluid to a separate fluid connection housing assembly via the fluid connection adapter;

the stinger assembly further including a slew drive, the slew drive having a fixed portion and rotating portion thereof, wherein the fluid connection adapter is connected to the rotating portion of the slew drive such that rotation of the rotating portion enables corresponding rotation of the fluid connection adapter;

a nightcap bracket, the nightcap bracket also connected to the rotating portion of the slew drive such that rotation of the rotating portion of the slew drive also enables corresponding rotation the nightcap bracket;

a nightcap, wherein the nightcap is selectably connectable to the nightcap bracket via a remotely-controlled nightcap engage/release mechanism, wherein the nightcap is longitudinally opposed to the fluid connection adapter when the nightcap is connected to the nightcap bracket;

wherein, when the nightcap is connected to the nightcap bracket, rotation of the rotating portion of the slew drive enables presentation of the fluid connection adapter and the nightcap interchangeably to the fluid connection housing assembly.

15. The fluid delivery unit of claim 14 , in which the nightcap includes a nightcap engagement pin, wherein the nightcap engagement/release mechanism is disposed to selectably engage and release the nightcap engagement pin, wherein release of the nightcap engagement pin enables the nightcap bracket to disconnect from the nightcap.

16. The fluid delivery unit of claim 15 , in which displacement of the nightcap engagement/release mechanism over the nightcap engagement pin enables the nightcap bracket to connect to the nightcap.

17. The fluid delivery unit of claim 14 , in which rotation of the rotating portion of the slew drive is remotely controlled.
