Seismic station Geometrics CNT-2

The Deck Unit serves as the main panel for connections to the GeoEel, and runs on 60 VDC
(supplied). It serves several functions, including:

  • Provides power to and communication with A/D modules.
  • Accepts trigger signal from external source (usually a source controller).
  • Optionally provides a trigger output to fire source.
  • Provides interface between bird control system and birds.
  • Provides auxiliary channels.
  • Provides streamer leakage, voltage, and current tests.

Air gun Seamap Sleeve Gun 40 Cubic Inch и 10 Cubic Inch

The Seamap Sleeve Gun offers several key benefits over traditional air guns.

  • Improved safety – Sleeve Guns can be retrieved and deployed without being pressurized.
  • Signature reliability and 4D repeatability – Traditional air guns use multiple ports, and the resulting discharge of air becomes rapidly disorganized. In a compact array, these disorganized bubbles can interfere with each other in an unpredictable and non-repeatable fashion. Seamap’s Sleeve Gun uses a single 360 degree port, resulting in a predictable, spherical bubble with a reliable and repeatable interaction with adjacent guns.

Depth Control

Maintaining cables at a constant depth can improve the image quality and safety of marine data acquisition but is challenging due to variability introduced by ocean currents. ION’s universally compatible streamer leveling technology is used by virtually every seismic contractor and is proven to deliver:

  • Increased positional accuracy and flexibility through integration with acoustics and heading sensors
  • Reduced HSE risk by enabling operator to surface or dive cables to avoid obstacles or tangles

Low maintenance and cost of ownership
