Abstract

A method and apparatus for deploying a plurality of seismic sensor units into a water column is provided. In one embodiment, a marine vessel is provided. The marine vessel includes a node storage and handling system disposed on a deck of the vessel. The node storage and handling system comprises a cable handler positioned adjacent a workstation proximate to a stern of the vessel, a node storage rack positioned between a bow and the stern of the vessel, the workstation being substantially parallel to a length of the node storage rack, and at least a first conveyor and a second conveyor positioned between the node storage rack and the workstation, wherein one of the first conveyor or the second conveyor is vertically movable relative to the node storage rack.

Claims (33)

1. A marine vessel, comprising:

a node storage and handling system disposed on a deck of the vessel, the node storage and handling system comprising:

a cable handler positioned adjacent a workstation proximate to a stern of the vessel;

a node storage rack positioned between a bow and the stern of the vessel, the workstation being substantially parallel to a length of the node storage rack; and

at least a first conveyor and a second conveyor positioned between the node storage rack and the workstation, wherein one of the first conveyor or the second conveyor is vertically movable relative to the node storage rack.

2. The vessel of claim 1 , wherein the cable handler comprises a first sheave and a second sheave.

3. The vessel of claim 2 , wherein the first sheave is coupled to a motor.

4. The vessel of claim 2 , wherein the cable handler further comprises:

one or more guide wheels providing compressive force to a peripheral surface of the first sheave or the second sheave.

5. The vessel of claim 1 , wherein the node storage rack comprises one or more conveyor sections.

6. The vessel of claim 5 , wherein the one or more conveyor sections are vertically stacked.

7. The vessel of claim 5 , wherein the one or more conveyor sections are positioned side by side.

8. The vessel of claim 5 , wherein the one or more conveyor sections are positioned end to end.

9. The vessel of claim 1 , wherein the first conveyor is substantially normal to the second conveyor.

10. A marine vessel, comprising:

a node storage and handling system disposed on a deck of the vessel, the node storage and handling system comprising:

a cable handler positioned adjacent a workstation disposed on the deck of the vessel, the cable handler comprising a powered sheave and an idler sheave positioned adjacent the powered sheave;

a node storage rack positioned between a bow and a stern of the vessel; and

at least a first conveyor and a second conveyor positioned between the node storage rack and the workstation, wherein one of the first conveyor or the second conveyor is vertically movable relative to the node storage rack.

11. The vessel of claim 10 , wherein the first conveyor is oriented substantially normal to the second conveyor.

12. The vessel of claim 10 , wherein the node storage rack comprises one or more conveyor sections.

13. The vessel of claim 12 , wherein the one or more conveyor sections are vertically stacked.

14. The vessel of claim 12 , wherein the one or more conveyor sections are positioned side by side.

15. The vessel of claim 12 , wherein the one or more conveyor sections are positioned end to end.

16. A marine vessel, comprising:

a node storage and handling system disposed on a deck of the vessel, the node storage and handling system comprising:

a cable handler positioned adjacent a workstation disposed on the deck of the vessel, the cable handler comprising a powered sheave and an idler sheave positioned adjacent the powered sheave;

a node storage rack positioned between a bow and a stern of the vessel; and

a first conveyor and a second conveyor positioned between the node storage rack and the workstation, the first conveyor being positioned substantially normal to the second conveyor, wherein one of the first conveyor or the second conveyor is vertically movable relative to the node storage rack.

17. The vessel of claim 16 , wherein the node storage rack comprises one or more conveyor sections.

18. The vessel of claim 17 , wherein the one or more conveyor sections are vertically stacked.

19. The vessel of claim 17 , wherein the one or more conveyor sections are positioned side by side.

20. The vessel of claim 17 , wherein the one or more conveyor sections are positioned end to end.
