Abstract: Method and streamer connecting module for connecting streamer sections to each other. The streamer connecting module includes a housing extending along a longitudinal axis (L) so that first and second ends are opposite to each other; a first streamer connecting part fixedly attached at the first end of the housing; a second streamer connecting part fixedly attached at the second end of the housing; first plural balls located between the first streamer connecting part and the first end of the housing; and a first conduit formed at an interface between the first streamer connecting part and the first end of the housing for accommodating the first plural balls.

Abstract: Method and flush module for connecting streamer sections to an external device. The flush module includes a housing; a first end connector attached to the housing and configured to connect to a first element of the streamer spread; a second end connector attached to the housing and configured to connect to a second element of the streamer spread; and an external connector attached to the housing and configured to connect to a third element of the streamer spread. The external connector is configured to pivot between (a) a close position during which the external connector is entirely located within the housing, and (b) an open position during which a distal end of the external connector is located outside the housing.
