The towed seismic cable of a neutral buoyancy for marine high-resolution seismic exploration is made on the basis of molecular-electronic hydrophones.
Towed seismic cables based on hydrophones are used in the oil&gas industry for the seismic exploration of hydrocarbons as well as for risk assessment while constructing drilling platforms and infrastructure facilities in the sea such as bridges, underwater tunnels, ports, coastal power plants, oil&gas pipelines.
Research centers can use towed seismic cables to conduct research works.
The length of the cable is about 15 meters including 10 hydrophones inside with the distance between the hydrophones of 1.5±0.1 m.
The sensitivity of one hydrophone channel is 500 μV/Pa, the signal type is analog.
