Abstract: 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.

Abstract: A low-vibration collar system for vibration mitigation in a device towed in water. The low-vibration collar system includes a clamp attached to a streamer towed underwater by a seismic vessel, the streamer comprising a plurality of sensors to record seismic data; a collar configured to be attached to the clamp; a connecting mechanism located on the collar and configured to attach an ancillary device to the collar; and a vibration mitigation system configured to attenuate an amplitude of a vibration produced by the ancillary device. The vibration interferes with seismic data recorded by seismic sensors located on the streamer.

Abstract: A communication method is provided in a communication network, including a plurality of devices forming an ordered communication segment. At least one intermediate device of this segment is connected to at most two other devices called a previous device and a next device. The intermediate device receives data from the previous device and emits at least these data to the next device to propagate the data on the segment. A concentrator initializes transmission of a first frame of data through the segment to a terminal device ending the segment, which sends back a symbol initiating transmission of a second frame of data to the first concentrator through the segment. The method includes receiving a first symbol from the previous device, which triggers emitting a WAIT symbol to the previous device and emitting at least first symbol to the next device.

Abstract: A method and marine seismic processing system including an interface for receiving recorded data, wherein the recorded data includes seismic data and bio-acoustic data; a seismic data processor for estimating a source signature from the recorded data, wherein the source signature is associated with a seismic source that emits seismic waves in water during a seismic survey; and a bio-acoustic processor that estimates a presence of a mammal generating the bio-acoustic data, based on a processed signal obtained by removing the source signature from the recorded data.

Abstract: A method is provided for managing a master vessel change in a multi-vessel seismic system. The system includes a master vessel M and at least one slave vessel. The method includes, during at least a part of a multi-vessel operation: selecting a new master vessel M′ among the at least one slave vessel, triggered by at least one predetermined event; and transmitting, to the at least one slave vessel, at least one piece of information related to a master vessel change from the master vessel M, called old master vessel, to the new master vessel M′.

Abstract: 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.

Abstract: A torque relief system dissipates a torque in a marine cable section to be used for seismic data collection. The system includes a bench having a deadman unit; a tensioning element connected to the deadman unit; a swivel bearing unit connected to the tensioning element and configured to receive a first end of the marine cable section; and at least one bearing unit configured to support the marine cable section with reduced friction so that when the tensioning element tenses the marine cable section, the marine cable section and the first end rotate freely until the torque is dissipated.

Abstract: A stress relief device is provided for a connector. The connector is connected to a cable and configured for cooperating with a complementary connector along a longitudinal axis. The stress relief device includes: an anchor configured for being placed around a portion of the cable so as to allow a stress relief of the portion of the cable, the portion of the cable being adjacent to the connector; a shell configured for being connected to the anchor and for at least partially wrapping the connector; and a locking system configured for connecting and locking the shell to a similar shell of a similar stress relief device for the complementary connector. The stress relief device is detachably mountable on the connector and is configured such that its mounting/dismounting does not require any change in the connection/disconnection of the connectors to one another.
