Abstract: A vibration isolation section (20) for use in a seismic streamer system, the section (20) including: a resilient sheath (30) arranged to be connected end-to-end in a seismic streamer (16) system and receive axial loads transmitted through the system, wherein the resilient sheath (30) is configured to stretch upon receiving an axial load and substantially convert the axial load into a radial stress; and a first support structure (42) housed within a first portion (31) of the resilient sheath(30), the first support structure (42) including one or more members having substantially constant diameter under load which provides a reaction to the radial stress, thereby reacting to the received axial load; and a second support structure housed at least in part within a second portion (33) of the resilient sheath(30), the second support structure including an enclosed fixed volume fluid filled flexible chamber (46) at least partially housed within the second portion (33) of the resilient sheath (30), the fluid filled f
Abstract: According to the present invention there is provided a vibration isolation section for use in a seismic streamer system, the section including: a resilient sheath arranged to be connected end-to-end in a seismic streamer system and receive axial loads transmitted through the system, wherein the resilient sheath is configured to stretch upon receiving an axial load and substantially convert the axial load into a radial stress; and a support structure housed within the resilient sheath, the support structure including one or more members having substantially constant diameter under load which provides a reaction to the radial stress, thereby providing attenuation to the received axial load.
