Abstract: A seismic data acquisition system includes at least one marine seismic streamer towed by a vessel. The at least one seismic streamer includes a seismic telemetry cable, extending along the at least one seismic streamer and adapted to communicate seismic data with the vessel, and connecting modules to which is connected an auxiliary equipment. Each connecting module is connected to the seismic telemetry cable, enabling the auxiliary equipment to communicate auxiliary data with the vessel, via the connecting module and the seismic telemetry cable.

Abstract: A method for estimating a tilt angle β(t) of at least one given particle motion sensor nearly collocated, in a multi-sensor streamer for seismic prospection, with a pressure sensor. The given particle motion sensor has two orthogonal sensing axes Y and Z in a plane orthogonal to a longitudinal axis of the streamer. The tilt angle is formed by the Z sensing axis and a reference vertical axis Z0. The method comprises, for the given particle motion sensor, a step of computing a first estimate β0 of the tilt angle, comprising, while the streamer is being towed: obtaining (41) first data measured by the pressure sensor nearly collocated with the given particle motion sensor; obtaining (42) second and third data measured by the given particle motion sensor along the sensing axes Y and Z respectively; for at least two values of a rotation angle θ, rotating (45) the second and third data by the rotation angle θ, to obtain rotated second and third data; and computing (46-410) a particular value θmax among the at least two values of the rotation angle, which maximizes, over at least one frequency, a coherence function between the first data and the rotated third data, or between the first data and velocity data resulting from an integration of the rotated third data, the particular value θmax being equal to said first estimate β0. Step of computing a first estimate β0 of said tilt angle is processed independently of any seismic signal.

Abstract: A method for calculating a tension (T) in a towed antenna. The method includes towing the antenna in water, wherein the antenna includes plural particle motion sensors distributed along the antenna; measuring with the plural particle motion sensors vibrations that propagate along the antenna; calculating a value of a phase velocity (vp) of the vibrations that propagate along the antenna based on (1) an offset between two particle motion sensors and (2) a time delay of the vibrations that propagate from one of the two particle motion sensors to another one of the two particle motion sensors; selecting a relation that links the phase velocity (vp) to the tension (T); and using the value of the phase velocity and the relation to determine the tension (T) at various locations of the plural particle motion sensors along the antenna.
