Abstract
An apparatus for making a marine seismic streamer includes a conveyor for transporting assembled mechanical harness from a storage device therefor to a storage device for storing completed marine streamer. The apparatus includes a first extruder for filling the harness with a void fill material and a second extruder for depositing jacketing material onto the filled harness both extruders being intermediate the two storage devices. A means for changing state of the void filling material is disposed proximate an outlet of the first extruder. In one embodiment, the means for changing state includes a radiation source.
Claims22
An apparatus for making a marine seismic streamer, comprising:
- a conveyor for transporting assembled mechanical harness from a storage device therefor to a storage device for storing completed marine streamer, the assembled mechanical harness including at least one strength member, a plurality of seismic sensors positioned at spaced apart locations along the strength member, and a conductor harness having at least one conductor coupled to a respective signal output of each seismic sensor;
- a first extruder for filling the harness with a void fill material, the first extruder intermediate the storage device for the harness and the storage device for the completed streamer;
- means for causing a state change in the void fill material from liquid to gel disposed proximate an outlet of the first extruder;
- and
- a second extruder for depositing jacketing material onto the impregnated harness, the second extruder intermediate the storage device for the harness and the storage device for the completed streamer.
A method for making a marine seismic streamer, comprising:
- conveying assembled mechanical harness from a storage device therefor toward a storage device for completed streamer, the harness including at least one strength member, a plurality of seismic sensors disposed in spacers and positioned at spaced apart locations along the strength member, and a conductor harness having at least one conductor coupled to respective signal output of each seismic sensor;
- filling the harness with a void fill material intermediate the storage device for the harness and the storage device for completed streamer, the void fill material comprising a radiation curable gel;
- causing the void fill material to undergo a state change from liquid to gel proximate an end of a place at which the harness is filled with void material;
- extruding jacketing material onto the gel-filled harness;
- and
- conveying the gel-filled, extruded harness to the storage device therefor.
