Definitions
- the disclosure relates to tender barges used in association with drill ship floating drilling platforms. More specifically, the disclosure relates to a tender barge that can store materials used during drilling operations on a drill ship and that can store waste products resulting from such drilling operations until the drilling operations are completed and the drill ship is moved from the drilling location.
- the tender barge may also act as the mooring facility for the drilling vessel.
- Drill ships are one type of floating drilling platform that may be used to drill wellbores through formations below the bottom of a body of water such as a lake or the ocean. Drill ships may be used in environmentally sensitive areas such as the Arctic. Regulations governing drilling activities in such environmentally sensitive areas may require that no formation cuttings or other waste products, e.g, produced water and/or oil from a formation, resulting from drilling a wellbore be discharged into the water. Further, air pollution regulations may require that only a limited number of additional fossil fuel powered vessels be permitted to operated within a predetermined distance from the drill ship.
- tender vessel that can store sufficient quantities of consumables for drilling operations at one or more selected well locations and that can store waste products generated as a result of the drilling operations.
- a tender barge for a drill ship includes a hull internally segmented into compartments.
- the compartments are for storing wellbore drilling consumables and wellbore drilling waste.
- the hull has an opening therein for positioning under a moon pool of a drill ship.
- the barge hull further includes a support structure for contacting a bottom of a hull of a drill ship when the drill ship is positioned over the barge hull.
- the barge has a mooring system having capacity to either hold the barge in position or hold both the barge and the drill ship when the drill ship is fully supported by the barge out of the water over a wellbore location.
- a method for drilling a wellbore using a drill ship and a tender barge includes moving the tender barge to a well drilling location.
- the tender barge is moored on location.
- the drill ship is moved so that a moon pool therein is positioned over a corresponding opening in a hull of the tender barge.
- the tender barge is deballasted until a support structure on the hull thereof contacts a corresponding structure on a bottom of the drill ship. Thereafter the tender barge is ballasted to maintain the drill ship in a trim condition for drilling operations.
- FIGS. 1 , 2 and 3 show end views of an example tender barge.
- FIG. 4 shows a plan view of the tender barge anchored to the water bottom.
- FIG. 5 shows an oblique view of the example barge of FIG. 4 .

- FIG. 21 shows a plan view of the drill ship and barge of FIG. 20 .
- FIG. 22 shows a side view of the drill ship and barge of FIG. 21 .
- FIGS. 1 , 2 and 3 show end views of an example tender barge 10 for use in connection with a drill ship.
- the barge 10 may include a plurality of anchor lines 12 to moor the tender barge 10 to the water bottom.
- the barge 10 may include a support platform 10 A with a center opening 10 B to correspond to the position of the moon pool on the drill ship when the drill ship is moved over the tender barge 10 , as will be further explained below.
- the interior of the hull of the tender barge 10 may include segregated compartments (not shown separately) for storage of fuel, fresh water cement and other consumables used during drilling operations.
- barge hull may be used, for example, to store drill cuttings, waste water from drilling/production testing and any unburned liquids from such testing.
- the barge 10 is moved to a well location, for example, by a towing vessel. Other examples of the barge 10 may be self propelled. Once the barge 10 is moved to the well location, mooring lines 12 may be deployed and tensioned.
- FIG. 4 shows the barge 10 in plan view with the mooring lines 12 deployed in a selected pattern.
- FIG. 5 shows the example barge 10 in oblique view so that more of the barge features may be observed.
- FIG. 6 shows a side view of the barge 10 , wherein may be observed the opening 10 B in the hull to be positioned beneath the moon pool of the drill ship.
- FIG. 7 shows a plan view of an example drill ship 14 to illustrate the position of the drilling unit 14 A thereon and the position of the moon pool 14 B.
- FIG. 8 shows a cut away end view or cross sectional view of the drill ship 14 to illustrate the portions of the drill ship hull, particularly the moon pool 14 B, that are to be disposed over the barge ( 10 in FIG. 1 ).
- a side view of the drill ship 14 showing the approximate position of the water line 16 may be observed in FIG. 9 .
- the drill ship hull may be fully supported by buoyancy provided by the barge ( 10 in FIG. 1 ).
- the drill ship ( 14 in FIG. 7 ) is moved into position above the barge ( 10 in FIG. 1 ), and the barge may be deballasted (e.g., by pumping water out of ballast chambers therein) so that its buoyancy supports the weight of the drill ship ( 14 in FIG. 7 ).
- FIG. 10 shows an end view/cross sectional view of the drill ship 14 moved into position above the barge 10 , after the barge 10 has been moored as shown in FIG. 4 . Note that there is a gap between the base of the hull of the drill ship 14 and the support structure on the barge 10 . Thereafter the tender barge 10 is ballasted to maintain the drill ship 14 in a trim condition for drilling operations.
- FIG. 11 shows the barge 10 being deballasted.
- the support structure on the barge 10 is now in contact with the base of the drill ship 14 hull.
- FIG. 12 the barge 10 is fully deballasted and the drill ship 14 may be moved upwardly so that no part of the drill ship 14 hull is beneath the water surface.
- FIG. 13 shows the drill ship 14 disposed on the barge 10 , wherein the barge 10 is fully moored.
- FIG. 14 shows a side view of the drill ship 14 and barge 10 combination wherein the drill ship 14 is fully supported out of the water.
- the mooring system for the barge 10 and the amount of buoyancy provided by the barge 10 may be selected to maintain position of both the barge 10 and the drill ship 14 , and to fully support the weight in air of the drill ship 14 , including any downward force exerted by the drill ship 14 during drilling operations.
- Such downward force may be as much as is capable of being supported by the drilling unit, as a non-limiting example, two million pounds.
- FIG. 15 Another example of the barge 10 is shown in end view/cross section in FIG. 15 .
- the example shown in FIG. 15 may have buoyancy sufficient to hold the barge 10 in position when suitably moored, however, such example of the barge 10 may not be required to support the weight of the drill ship 14 .
- FIG. 16 Another end view/cross section of the present example barge 10 is shown in FIG. 16 .
- FIG. 17 shows the example barge 10 of FIGS. 15 and 16 in plan view, including a mooring system having been deployed.
- the number of mooring lines 12 may be fewer than the example shown in FIG. 13 because the barge mooring is not required to support the weight of the drill ship 14 .
- a side view of the present example barge 10 is shown in FIG. 18 .
- the barge 10 may be moved to a well drilling location and moored in place.
- the drill ship 14 may then be moved into position over the barge. This is shown in end view/cross section in FIG. 19 .
- the barge 10 may then be deballasted, as explained with reference to the previous example and shown in FIGS. 10 , 11 and 12 , however, as shown in FIG. 20 , the base of the drill ship 14 hull may just contact the support structure 10 A without transfer of any substantial amount of the weight of the drill ship 14 to the support structure 10 A.
- FIG. 21 shows a plan view of the barge and drill ship of the present example.
- FIG. 22 shows the barge 10 and drill ship 14 in side view.
- the drill ship 14 is immersed in the water, wherein the approximate position of the water line 16 on the drill ship 14 hull is shown.
- the drill ship 14 may be dynamically positioned, for example, using thrusters as known in the art.
- various lines may be rigid conduits having suitable swivel and other connections, or may be or may include flexible hose
- Pumps (not shown) to transfer the various materials stored in the barge to and from the drill ship may be located on the drill ship 14 , on the barge 10 or both.
- deballasting pump(s) may be disposed on the barge 10 .
- Such pumps may be powered by equipment on the barge 10 , or may be powered, for example by electric power communicated from the drill ship 14 .
- the barge 10 may be reballasted to come out of contact with the drill ship 14 (i.e., the drill ship 14 is in free flotation). The drill ship 14 may then move away from the wellbore location, e.g., to a next wellbore location. The barge 10 may then be unmoored, deballasted and moved to another location for emptying the compartments holding waste materials, and refilling the compartments storing the consumables to be used on a subsequent well drilling operation.
- a tender barge according to the various examples explained herein may provide wellbore drilling operators with means to eliminate discharge of drilling waste into the water, and may provide enough consumables to avoid the necessity of having any other self powered vessels approach the vicinity of the drill ship during drilling operations.
