Operating data of the streamer DigiSTREAMER active section

Active section (receiver portion) of the streamer is a part of DigiSTREAMER system for marine seismic data collection. Differential characteristics:

. Gelling agent of the filling provides the control of internal sound level and advantages of positive buoyancy.

. In-line groups of sensors with optimized hydrophone scheme (development patent) for noise level control.

. Hydrophones Teledyne T2BX with noise reduction due to acceleration in groups of sensors.

. Titanium batteries provide the reduction in weight, durability and rust protection
