Abstract

The invention relates to an apparatus and method for cable dynamic suppression, and relates to a 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; 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.

Description

technical field [0001] Embodiments of the subject matter disclosed herein generally relate to apparatus and methods for cable dynamic suppression. Background technique [0002] An electro-mechanical cable may be a cable such as a marine-seismiccable (also known as a marine-seismic streamer), which includes sensor components, data transmission cables, and , power transmission cables, and strength and buoyancy enhancement components. The marine seismic cable may be an electromechanical cable used to acquire data on the nature and composition of the land beneath the body of water using seismic imaging techniques. Marine seismic cables (or seismic streamers) can be designed such that flow noise caused by hydrodynamic forces is reduced. For example, marine seismic cables may be cylindrical. [0003] figure 1 An exemplary marine seismic cable system in use is depicted. Vessel 101 , which includes lead-intowing assembly 102 , may deploy and tow electromechanical cables 103 on ...
