Upon Request
All Exposed
In-Sea Metals
are Titanium.
Solid Seismic Cable Technologies, (SSCT) active sections are available
for both the SeaMUX and SeaTRAK systems. The SSCT Solid Streamer
is the first streamer to incorporate real time active flow noise
reduction by utilizing the properties of the PVDF Thin Film Technology
to create a multiple sensor configuration, where flow noise is sensed
independently from acoustic energy. SSCT’s patent pending
technology is combined with the acoustic output in such a way as
to significantly mitigate unwanted noise due to flow while preserving
acoustic amplitude and phase.
The Solid Streamer active section incorporates HTI’s Patent Pending
Active Flow Noise Cancelling hydrophones for significantly higher
overall signal to noise ratio. Low stretch HM center stress member,
torque balanced core cable design, and robust floatation all provide

Solid Seismic Cable
a uniquely stable and resilient
solid streamer design. Coupled
with Passive Flow Noise Cancelling
hydrophones, (Patent Pending
#61427775) HTI’s Solid Streamer
package provides unmatched
performance and durability in the
industry. All sections are equipped
with the SeaMUX connector tie off
adapter.
