Abstract

The present disclosure generally relates to an apparatus for storing, treating, and making up of various drilling fluids onboard a dynamically positioned vessel, such as a barge, boat, or shop. In particular, the present disclosure relates to a liquid mud plant (LMP) supporting any offshore drilling rig or platform from a vessel in closer proximity to that rig. Additionally, the present disclosure relates to the process by which the liquid mud plant is in closer proximity to the drilling, which is derived from the dynamical positioning capability of the liquid mud plant vessel.

Claims

1. A dynamically positioned liquid mud plant vessel, comprising:

a hull;

a deck on the hull;

a liquid mud plant positioned on the deck; and

a plurality of thrusters coupled with the hull, the thrusters rotatable and configured to stabilize the dynamically positioned liquid mud plant vessel.

2. The vessel of claim 1, wherein the liquid mud plant comprises at least one hopper, tank, pump, centrifuge, dryer, or treatment basin.

3. The vessel of claim 1, wherein the plurality of thrusters comprise a first thruster coupled to the bow, a second thruster coupled to the stern, and a third thruster coupled to the port or starboard side of the hull.

4. The vessel of claim 1, further comprising a controller coupled to the plurality of thrusters.

5. The vessel of claim 4, wherein the controller comprises a satellite positioning system, the controller configured to control the thrusters to maintain the vessel at a desired location.

6. A method of supplying a deep water platform, comprising:

positioning a dynamically positioned liquid mud plant vessel adjacent to a platform, the liquid mud plant vessel having a liquid mud plant thereon; and

providing supplies to the platform from the liquid mud plant vessel.

7. The method of claim 6, wherein the dynamically positioned mud plant vessel comprises a plurality of thrusters.

8. The method of claim 7, further comprising a controller, wherein the controller comprises a satellite positioning system, the controller configured to control the thrusters to maintain the vessel at a desired location.

9. The method of claim 6, wherein the dynamically positioned liquid mud plant comprises at least one hopper, tank, pump, centrifuge, dryer, or treatment basin.

10. The method of claim 6, wherein the dynamically positioned mud plant vessel is coupled to the platform by one or more pipes or hoses.

11. The method of claim 6, wherein the dynamically positioned liquid mud plant vessel treats one or more fluids used by the platform.

12. An offshore facility, comprising:

a vessel;

a platform, wherein the vessel is disposed adjacent to the platform; and

a controller, wherein the controller comprises a satellite positioning system coupled to a plurality of thrusters of the vessel, wherein the vessel is positioned adjacent to the platform by the operations of;

determining a desired coordinate position;

applying the coordinate position to the controller; and

controlling the plurality of thrusters in response to an output from the controller to position the vessel at a location corresponding to the desired coordinate position.

13. The offshore facility of claim 13, wherein the liquid mud plant vessel stores supplies for use by the platform.

14. The offshore facility of claim 13, wherein the vessel comprises a liquid mud plant.

15. The offshore facility of claim 14, wherein the liquid mud plant provides fluids for a drilling operation of the platform.
