Anti-barnacle net and method

1. An array of streamers to be used for a seismic survey, the array comprising:

at least one streamer including first and second sections, each section including at least a receiver for recording seismic data; and

a net provided over the first section to prevent barnacles to attach to the at least one streamer,

wherein the net is made of a combination of a synthetic material and a metal and further includes a piece of another metal provided on the at least one streamer to prevent a corrosion of metallic parts of the streamer.

2. The array of claim 1 , wherein the net is made of at least one of a synthetic material, a natural material, or a metal.

3. The array of claim 1 , wherein the metal is selected to be disliked by the barnacles.

4. The array of claim 1 , wherein the net is covered with a low-adhesion material or with an anti-stick material.

5. The array of claim 1 , wherein the net includes one or more cells having a size smaller than an average size of a larva of an barnacle.

6. The array of claim 1 , further comprising:

plural reservoirs placed at various locations along the net for storing and releasing a chemical substance.

7. A method for providing a net over a streamer, the method comprising:

rolling out the streamer from a vessel;

providing over the streamer a net for preventing barnacles to attach to the streamer; and

releasing the streamer covered with the net into water for performing seismic survey,

wherein the net is made of a combination of a synthetic material and a metal and further includes a piece of another metal provided on the at least one streamer to prevent a corrosion of metallic parts of the streamer.

8. The method of claim 7 , further comprising:

attaching a first end of the net at a first end of a section of the streamer; and

attaching a second end of the net at a second end of the section of the streamer.

9. The method of claim 8 , further comprising:

cutting the net at the second end.

10. The method of claim 8 , further comprising:

impregnating the net with a chemical substance disliked by a marine animal.

11. The method of claim 8 , further comprising:

providing the net around the streamer such that the net is allowed to vibrate relative to the streamer.

12. The method of claim 7 , wherein the net includes plural portions, each portion covering a corresponding section of the streamer.

13. The method of claim 7 , further comprising:

covering the net with a low-adhesion material or with an anti-stick material.

14. The method of claim 7 , further comprising:

providing the net to include one or more cells having a size smaller than an average size of a larva of a barnacle.

15. The method of claim 7 , further comprising:

attaching plural reservoirs at various locations along the net for storing and releasing a chemical substance.

16. A method for removing a net from a streamer when the streamer is brought back on a vessel, the method comprising:

releasing a streamer, from the vessel, into water, wherein at least a section of the streamer is covered with a net;

recording seismic data with the streamer;

retrieving the streamer back on the vessel; and

removing the net from the at least a section of the streamer when the streamer is on the vessel,

wherein the net is made of a combination of a synthetic material and strands of at least two different metals that are configured to generate an electric current when placed underwater.

17. An array of streamers to be used for a seismic survey, the array comprising:

at least one streamer including first and second sections, each section including at least a receiver for recording seismic data; and

a net provided over the first section to prevent barnacles to attach to the at least one streamer,

wherein the net is made of a combination of a synthetic material and strands of at least two different metals that are configured to generate an electric current when placed underwater.
