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 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: 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.
