Stabilized streamer connection system

A connection system for connecting external devices to a streamer, the connection system comprising:

• a first inner collar having an axial bore receiving a streamer, wherein the first inner collar is coaxially affixed to the streamer at a first location along the length of the streamer;
• a second inner collar having an axial bore receiving the streamer, wherein the second inner collar is coaxially affixed to the streamer at a second location along the length of the streamer;
• a first outer collar having an outer periphery and an inner axial bore for rotatably receiving the first inner collar;
• a third outer collar having an outer periphery and an inner axial bore for rotatably receiving the second inner collar;
• a second outer collar disposed between the first and third outer collars and having an outer periphery and an inner axial bore for receiving the streamer;
• a length-adjustable stabilizing member connected to the first, second, and third outer collars to maintain the axial bores of the outer collars in alignment and to adjust the distance between the second and third outer collars.

A connection system for connecting an external device having two attachment points separated by a first distance to a streamer having two spacer blocks separated by a greater second distance, the connection system comprising:

• a first inner collar having an axial bore receiving a streamer, wherein the first inner collar is coaxially affixed to the streamer at a first location along the length of the streamer corresponding to the location of a spacer block in the streamer;
• a second inner collar having an axial bore receiving the streamer, wherein the second inner collar is coaxially affixed to the streamer at a second location along the length of the streamer corresponding to the location of another spacer block in the streamer and separated from the first location by a distance corresponding to the separation of the spacer blocks in the streamer;
• a first outer collar having an outer periphery and an inner axial bore for rotatably receiving the first inner collar;
• a third outer collar having an outer periphery and an inner axial bore for rotatably receiving the second inner collar;
• a second outer collar disposed between the first and third outer collars and having an outer periphery and an inner axial bore for accommodating the streamer and spaced from the first outer collar by a distance corresponding to the separation of the two attachments points of an external device attachable to the first and second outer collars at the attachment points;
• a stabilizing member connected to the first, second, and third outer collars to maintain the axial bores of the outer collars in alignment.
