Abstract: A method of manufacturing a streamer section. The method includes coupling together a plurality of prefabricated harness modules. A harness module includes a plurality of geophysical sensors disposed along a length of the harness module and a sensor node communicatively coupled to the plurality of sensors. A first connector is disposed at a first end of the harness module and a second connector disposed at a second end of the harness module. The first connector is coupled to the sensor node and is configured to couple to a second harness module and receive data from a sensor node in the second harness module. The second connector is coupled to the sensor node and is configured to couple to a third harness module and forward data to a sensor node in the third harness module.

Abstract: A harness plug and methods of use. Example devices include an arcuate portion and a lateral portion disposed at an outer periphery of the arcuate portion. The arcuate portion is configured to engage with arcuate portion of a hole within a spacer. A method of using the harness plug includes molding a harness plug about a portion of a cable bundle and inserting the cable bundle into an arcuate portion of a hole in the spacer through a lateral portion of the first hole. The harness plug is pressed into the arcuate portion of a hole in the spacer. A streamer spacer for use with the harness plug includes a hole having a portion having an arcuate shape and a second portion lateral to and abutting the arcuate portion and extending to a periphery of an elongate body of the streamer spacer.

Abstract: A method for making a marine electromagnetic survey streamer includes affixing connectors to longitudinal ends of a strength member. At least one signal communication line is extended along the length of the strength member. The strength member, connectors, and at least one signal communication line form a mechanical harness. Electrodes are affixed to the mechanical harness at selected positions. The mechanical harness is drawn through a co-extruder. The co-extruder fills void spaces in the harness with a void fill material. The co-extruder applies a jacket to an exterior of the void filled harness.
