Abstract
A marine sensor streamer includes a jacket covering an exterior of the streamer. At least one strength member extends the length of the jacket. At least one stiffener element extends inside the length of the jacket. The at least one stiffener element includes a gas filling the interior of a flexible, compressible tube and filler elements disposed in the gas. The filler elements have exterior shape and surface roughness such that upon compression of the gas, the filler elements are urged into contact with each other, causing the streamer to become substantially rigid.

A marine sensor streamer, comprising:
- a jacket covering an exterior of the streamer;
- at least one strength member extending the length of the jacket;
- at least one stiffener element extending inside the length of the jacket, the at least one stiffener including a gas filling the interior of a flexible, compressible tube and filler elements disposed in the gas, the filler elements having exterior shape and surface roughness such that upon compression of the gas, the filler elements are urged into contact with each other, causing the streamer to become substantially rigid.
