Tension monitoring method and system for towed antenna

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.. ...

System and method for parameter measurement in well

System and method for measuring a parameter within a well. The method includes connecting a gauge to a first end of a cable and connecting a vector network analyzer to a second end of the cable, lowering the gauge inside the well, generating a signal with the vector network analyzer and sending the signal along the cable to the gauge, sweeping a frequency of the signal within a given range while feeding the signal to the gauge, determining a resonance frequency of at least one sensor located within the gauge, and calculating the parameter from the resonance frequency of the at least one sensor.. ...

Method for localizing a marine mammal in an underwater environment implemented by a pam system, corresponding device, computer program product and non-transitory computer-readable carrier medium

. . A method for localizing a marine animal in an underwater environment implemented by a passive acoustic monitoring (pam) system. The passive acoustic monitoring system includes network of acoustic sensors adapted to carry out measurements of acoustic signals. ... Sercel

Average clock adjustment for data acquisition system and method

A system and method for adjusting a clock signal of a seismic data acquisition system. The system includes a data acquisition device having an oscillator that generates a clock signal; a clock adjustment module that receives a time reference signal and the clock signal and outputs an adjusted clock signal; and an analog-to-digital convertor configured to transform analog data into digital data having a sampling rate (fdata). ... Sercel

Method for managing a network, and node for implementing said method

There is provided a method for electing a master routing node of a given subnet of a network, comprising: determining (71) a first-type address associated with an interface of each node on the given subnet, and being the address given by a routing table of the next hop (router node or target node) on the path leading from the node to a target node; determining (72) a second-type address associated with the interface of each node on the given subnet, and being either the determined first-type address (if the latter is on the given subnet) or the address of the interface of the node on the given subnet (if the determined first-type address is on another subnet); sending (73) by each router node of the given subnet a message containing its determined second-type address; collecting (74) at the interface of each node on the given subnet the sent messages; selecting (75) for the interface of each node on the given subnet a third-type address among its determined second-type address and the second-type addresses contained in the collected messages, according to a selection rule known by all nodes of the subnet; electing (76) as master routing node of the given subnet the node having the selected third-type address.. . ... Sercel

Coupling device for seismic sensors

A coupling device is provided for a sensor unit having at least one sensor located within a housing. The coupling device includes at least one supporting portion, wherein the supporting portion is configured for maintaining the sensor unit in a stable position, with the coupling device either resting on or being buried into the ground, and at least one rod, arranged in a plane which is essentially perpendicular to a peripheral surface of the supporting portion and linked to the supporting portion. ...
