Offshore

NCA offers a broad range of airgun packages for shallow and deep water applications, all of which reflect our design objectives:

  • Ease of Operation    
  • Minimal Maintenance
  • High Availability      

Offshore seismic exploration is the primary method of exploring for hydrocarbon deposits under the sea.

                                                                                                                         
It begins on the ocean surface with a fleet of seismic vessels. Air guns are used to shoot sound energy waves from the survey ship into the water and sea bottom. Different layers of sedimentary rock reflect unique parts of the sound waves back to shipboard receptors.

The data is analyzed by software to produce a 3-D image of the underground environment and to map structural traps that could potentially contain hydrocarbons. 


NCA compound compressors are installed on the survey ship to load the air guns which create the shock waves.
