Abstract: Method and apparatus for mitigating vibrations in a device towed in water. The apparatus includes one or more tuned elastic sections having a complex spring rate and adapted to attenuate vibrations in a specified frequency range; and a head end coupler adapted to couple the apparatus for vibration mitigation to a component of an electro-mechanical cable or a tow assembly. One of the one or more tuned elastic sections is coupled to the head end coupler with a high impedance material interface.

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: Method and dynamic vibration absorber device for reducing a resonant frequency of a node to which the dynamic vibration absorber device is attached to. The dynamic vibration absorber device includes a housing configured to be attached to the node; an absorber mass located inside the housing; and first and second diaphragms attached to the housing and configured to suspend the absorber mass inside the housing. The dynamic vibration absorber device changes a resonant frequency of the node to two smaller vibration peaks.
